All questions

Question 1

In fall, a bear eats berries and fish; how is that energy used?​

  1. walking, growing, staying warm, and building fat stores (correct answer)
  2. making food from sunlight, walking, and staying warm
  3. only storing energy, never using it, and not moving
  4. releasing energy into the air, growing, and staying warm
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When a bear eats berries and fish in fall, it uses that food energy for four important purposes: (1) Walking and all other movements including breathing, heartbeat, and foraging; (2) Growing new fur, building muscle, and general body maintenance; (3) Staying warm by maintaining body temperature around 37°C; (4) Building fat stores for winter hibernation when food will be scarce. Choice A is correct because it identifies walking (movement), growing (growth), staying warm (temperature regulation), and building fat stores (energy storage for future use) as key uses of food energy. Choice B fails because it suggests bears can make food from sunlight like plants do through photosynthesis, when only plants can convert sunlight to food - bears must eat berries, fish, and other foods for energy. To help students understand: Explain seasonal energy needs - 'In fall, bears eat extra food not just for today's activities but to store energy as fat for winter hibernation when they won't eat for months.' Show how stored fat is like a battery, saving energy for later use during hibernation.

Question 2

A penguin eats fish; how does it use the energy it gets from food?

  1. swimming and walking, growing, and staying warm (correct answer)
  2. photosynthesis to make food from sunlight
  3. only for movement, not for warmth or growth
  4. creating more energy instead of using food energy
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways. (1) Growth: Animals use energy to build new cells and tissues, to grow bigger and taller, to develop new body parts, to heal injuries, and to replace old cells. Growing requires energy because the body is building new living material. (2) Movement: All movement uses energy—not just obvious movement like running or flying, but also breathing (chest muscles moving), heartbeat (heart muscle pumping), digestion (stomach and intestines moving food), and even tiny movements like blinking. (3) Warmth: Mammals and birds are warm-blooded, meaning they maintain a constant body temperature even when the environment is cold. Keeping the body at 37-38°C requires energy—the body is constantly generating heat using energy from food. Even when an animal is resting and not moving much, it still uses energy for breathing, heartbeat, and staying warm. Choice A is correct because it accurately identifies multiple body activities that require energy, such as swimming and walking, growing, and staying warm. This demonstrates understanding that animals use energy from food for multiple purposes simultaneously—they're growing AND moving AND staying warm, all using energy from the food they ate. Choice B fails because it claims animals use energy for photosynthesis to make food from sunlight, when only plants can make food through photosynthesis. Animals cannot make food like plants do—they must eat food to get energy, and they use that energy for growth, movement, warmth, and all life processes. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth.' Have students brainstorm activities that fit each category. Growth: getting taller, building muscle, healing cuts, growing new hair, baby animals growing up. Movement: running, flying, walking, breathing, heartbeat, digesting food, talking. Warmth: keeping body at 37°C, staying warm on cold days, generating body heat. Emphasize that ALL of these require energy from food. Use personal examples: 'When you eat breakfast, your body uses that energy for growing (you get taller and stronger), moving (you walk to school, write in class, play at recess), and staying warm (your body stays at 37°C even when it's cold outside).' Demonstrate energy use even at rest: 'Even when you're sitting still, your heart is beating, you're breathing, your body is warm—all of this uses energy from your food.' Watch for: Students who think animals can make food like plants, or who think only movement requires energy (miss that growth and warmth also require energy). Reinforce: All animal activities use energy. Energy comes from food. Food energy originally came from sun through plants.

Question 3

A deer eats grass; which activities require energy from its food?

  1. breathing and heartbeat, walking, and staying warm (correct answer)
  2. making food from sunlight, air, and water
  3. storing all energy as fat and using none
  4. only growing antlers, not movement or warmth
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1).

Question 4

A hummingbird drinks nectar; energy from the food is used for what?

  1. rapid flying, staying warm, and growing new tissue (correct answer)
  2. photosynthesis to make food inside its body
  3. only resting quietly, not movement or warmth
  4. releasing energy into the air instead of using it
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways.

Question 5

A kitten drinks milk; the kitten uses energy from food for what?

  1. growing, playing and moving, and keeping warm (correct answer)
  2. making its own food from sunlight and air
  3. only for warmth, not for movement or growth
  4. sharing all its energy with other animals nearby
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1).

Question 6

A cheetah eats meat; which uses of energy from food are correct?

  1. running fast, growing and healing, and staying warm (correct answer)
  2. turning sunlight into food and storing it
  3. only for running, not for warmth or growth
  4. producing energy without eating any food
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways.

Question 7

A sloth eats leaves; what does the sloth's body use food energy for?

  1. moving slowly, growing, and keeping its body warm (correct answer)
  2. making food from sunlight like a plant does
  3. only for growing, not for movement or warmth
  4. creating new energy instead of using food energy
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways.

Question 8

A cheetah eats meat; what does its body use that food energy for?

  1. running fast, growing, and keeping a steady temperature (correct answer)
  2. creating new energy, running fast, and making more energy
  3. only for growth, not for movement or warmth
  4. sharing energy with plants, growing, and staying warm
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When a cheetah eats meat, it uses that food energy for three main purposes: (1) Running fast - cheetahs can reach 70 mph, requiring enormous energy for their powerful muscles, plus energy for breathing, heartbeat, and all other movements; (2) Growing new cells, building muscle, replacing worn tissues, and healing any injuries from hunting; (3) Keeping a steady temperature around 38°C regardless of whether it's hot midday or cool at night. Choice A is correct because it identifies running fast (movement), growing (growth), and keeping a steady temperature (temperature regulation) as key uses of food energy. Choice B fails because it claims cheetahs can create new energy, when animals can only transform energy from food, not create energy from nothing - this violates the law of conservation of energy. To help students understand: Use the cheetah as an example of high energy needs - 'The world's fastest land animal needs lots of energy from meat to power its incredible speed, grow strong muscles, and maintain body temperature in the African savanna.' Emphasize that energy is transformed, not created: meat energy → cheetah's movement, growth, and warmth.

Question 9

A cheetah eats meat; what does its body use that food energy for?​

  1. running fast, growing, and keeping a steady temperature (correct answer)
  2. creating new energy, running fast, and making more energy
  3. only for growth, not for movement or warmth
  4. sharing energy with plants, growing, and staying warm
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1).

To help students understand: Use the cheetah as an example of high energy needs - 'The world's fastest land animal needs lots of energy from meat to power its incredible speed, grow strong muscles, and maintain body temperature in the African savanna.' Emphasize that energy is transformed, not created: meat energy → cheetah's movement, growth, and warmth.

Question 10

A kitten eats fish; how does it use energy from that food?

  1. grow, play and move, and stay warm (correct answer)
  2. convert sunlight into food like a plant
  3. only grow, not for movement or warmth
  4. store all energy as fat and never use it
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth, such as building new cells and tissues to grow bigger, develop, heal, and replace old cells; (2) Movement, including playing, breathing, heartbeat, digestion, and blinking; (3) Warmth, maintaining constant body temperature in mammals by generating heat. Choice A is correct because it accurately identifies grow, play and move, and stay warm as multiple uses of food energy, showing the kitten uses fish energy for development, activity, and temperature simultaneously. Choice B fails because it claims animals convert sunlight into food like plants, when animals must eat for energy; this addresses the misconception of animals photosynthesizing. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth,' have students list like growing fur for growth, pouncing for movement, and cozy warmth; use pet examples; emphasize energy even at rest, countering storage-only or single-use ideas.

Question 11

A robin eats a worm; what does it use that food energy for?

  1. flying, growing new feathers, and staying warm (correct answer)
  2. making food from sunlight, flying, and building nests
  3. storing all energy forever, never using it, and sleeping
  4. creating more energy, releasing it, and producing new energy
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When a robin eats a worm, it digests the food to release energy for three main purposes: (1) Flying and all other movements including hopping, breathing, and heartbeat; (2) Growing new feathers to replace old ones, building muscle tissue, and general body growth; (3) Staying warm by maintaining a constant body temperature around 40°C, which is especially important for small birds that lose heat quickly. Choice A is correct because it accurately identifies flying (movement), growing new feathers (growth), and staying warm (temperature regulation) as key uses of food energy. Choice B fails because it claims robins can make food from sunlight, when only plants can perform photosynthesis - birds must eat food like worms, insects, or berries to get energy. To help students understand: Show how even small animals like robins need lots of energy - 'A robin's heart beats 400 times per minute, it must stay warm even on cold mornings, and it grows new feathers regularly - all requiring energy from the worms and insects it eats.' Watch for students who think only large movements like flying use energy, missing that growth and warmth also require energy.

Question 12

A deer eats grass; which activities require energy from its food?​

  1. running, growing antlers, and keeping warm in winter (correct answer)
  2. making its own food, growing antlers, and running fast
  3. only chewing, not warmth or growth, and no running
  4. getting energy from breathing, growing, and staying warm
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When a deer eats grass, it extracts energy through digestion to power three main activities: (1) Running and all movements including walking, chewing, breathing, and heartbeat; (2) Growing antlers (in males), building muscle, getting bigger, and replacing old cells; (3) Keeping warm in winter by maintaining body temperature around 38°C even when it's freezing outside. Choice A is correct because it identifies running (movement), growing antlers (growth), and keeping warm in winter (temperature regulation) as activities requiring food energy. Choice B fails because it suggests deer can make their own food like plants do, when only plants can convert sunlight to food through photosynthesis - deer must eat plants to get energy. To help students understand: Use seasonal examples - 'In spring, male deer use grass energy to grow new antlers; in summer, they use it for running from predators; in winter, they use extra energy to stay warm in the snow.' Emphasize that herbivores like deer get their energy from plants, which originally got energy from the sun, showing the energy flow: sun → grass → deer.

Question 13

A cheetah eats meat; what does food energy help the cheetah do?​

  1. run fast, grow, and keep a warm body (correct answer)
  2. turn sunlight into energy like a leaf
  3. only digest food, not move or stay warm
  4. produce brand-new energy inside its body
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth, such as building new cells and tissues to grow bigger, heal, and replace old cells; (2) Movement, including running fast, breathing, heartbeat, digestion, and blinking; (3) Warmth, maintaining constant body temperature in mammals by generating heat. Choice A is correct because it accurately identifies run fast, grow, and keep a warm body as the main uses of food energy, demonstrating the cheetah uses meat energy for speed, development, and temperature regulation simultaneously. Choice D fails because it states animals produce brand-new energy inside their body, when animals only transform food energy, not create it, addressing the misconception of energy creation. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth,' brainstorm like muscle building for growth, chasing prey for movement, and heat in savanna for warmth; use fast animal examples; reinforce resting energy for heartbeat and warmth, countering single-use or creation ideas.

Question 14

Sofia eats a sandwich and apple; how does her body use food energy?​

  1. growing, moving, and keeping a steady body temperature (correct answer)
  2. converting sunlight to energy, growing, and running
  3. only for movement, not for growth or warmth
  4. absorbing water, making vitamins, and changing food color
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When Sofia eats a sandwich and apple, her body breaks down the food to release energy that powers three main activities: (1) Growth - energy builds new cells for getting taller, developing muscles, healing injuries, and replacing old cells; (2) Movement - energy powers all movement from walking and writing to breathing and heartbeat; (3) Keeping a steady body temperature - humans maintain 37°C body temperature regardless of environmental temperature, which requires constant energy use. Choice A is correct because it accurately identifies growing, moving, and keeping a steady body temperature as the three main uses of food energy in animals. Choice B fails because it suggests humans can convert sunlight to energy like plants do through photosynthesis, when only plants can make food from sunlight - humans must eat food for energy. To help students understand: Use personal examples - 'When you eat lunch, that energy helps you grow taller (growth), play at recess and breathe (movement), and stay warm even in a cold classroom (warmth).' Emphasize that even sitting still uses energy for breathing, heartbeat, and maintaining body temperature.

Question 15

A penguin eats fish; what does it use food energy for each day?

  1. swimming, growing, and staying warm in cold weather (correct answer)
  2. turning sunlight into energy, swimming, and staying warm
  3. only for movement, not warmth or growth
  4. storing all energy forever, never using it, and floating
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. When a penguin eats fish, it uses that food energy for three critical daily activities: (1) Swimming through cold ocean water using powerful flippers, plus walking, breathing, and heartbeat; (2) Growing new feathers to replace old ones, building muscle, and general body growth; (3) Staying warm in extremely cold Antarctic conditions where air temperatures can reach -40°C and water is near freezing. Choice A is correct because it identifies swimming (movement), growing (growth), and staying warm in cold weather (temperature regulation) as essential uses of food energy. Choice B fails because it suggests penguins can turn sunlight into energy, when only plants can perform photosynthesis - penguins must eat fish and other sea animals to get energy. To help students understand: Emphasize extreme conditions - 'Penguins live in the coldest place on Earth and swim in freezing water, so they need lots of energy from fish to stay warm and active.' Explain how penguins huddle together to conserve energy for warmth, showing that staying warm in Antarctica requires constant energy use from food.

Question 16

A kitten eats fish; how does it use energy from that food?​

  1. grow, play and move, and stay warm (correct answer)
  2. convert sunlight into food like a plant
  3. only grow, not for movement or warmth
  4. store all energy as fat and never use it
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth, such as building new cells and tissues to grow bigger, develop, heal, and replace old cells; (2) Movement, including playing, breathing, heartbeat, digestion, and blinking; (3) Warmth, maintaining constant body temperature in mammals by generating heat. Choice A is correct because it accurately identifies grow, play and move, and stay warm as multiple uses of food energy, showing the kitten uses fish energy for development, activity, and temperature simultaneously. Choice B fails because it claims animals convert sunlight into food like plants, when animals must eat for energy; this addresses the misconception of animals photosynthesizing. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth,' have students list like growing fur for growth, pouncing for movement, and cozy warmth; use pet examples; emphasize energy even at rest, countering storage-only or single-use ideas.

Question 17

A puppy eats dog food and uses that food energy for what activities?​

  1. making its own food from sunlight, growing, and running
  2. growing bigger, moving around, and staying warm (correct answer)
  3. storing all energy as fat, never using it, and resting
  4. creating new energy, sharing it, and making more energy
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth - puppies use energy to build new cells, grow bigger, develop muscles and bones, and replace old cells; (2) Movement - all movement uses energy including running, playing, breathing, heartbeat, and even tail wagging; (3) Warmth - dogs are warm-blooded mammals that maintain a constant body temperature around 38°C, which requires continuous energy use. Choice B is correct because it accurately identifies all three main uses of food energy: growing bigger (growth), moving around (movement), and staying warm (maintaining body temperature). Choice A fails because it claims puppies can make their own food from sunlight, when only plants can perform photosynthesis - animals must eat food to get energy. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth.' Have students brainstorm puppy activities for each category - Growth: getting bigger, growing new teeth, building muscles; Movement: running, jumping, playing, breathing, heartbeat; Warmth: keeping body at 38°C even on cold days.

Question 18

Even when a dog is sleeping, what does it use food energy for?​

  1. breathing, heartbeat, and staying warm while it rests (correct answer)
  2. making its own food, breathing, and heartbeat movements
  3. creating energy, breathing, and producing more energy
  4. no energy for warmth, only dreaming and tail wagging
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Even when a dog is sleeping and appears inactive, its body continuously uses energy from food for three vital functions: (1) Breathing - the chest muscles must contract and relax to move air in and out of the lungs about 10-30 times per minute; (2) Heartbeat - the heart muscle pumps blood throughout the body 70-120 times per minute, never stopping; (3) Staying warm - maintaining body temperature at 38°C requires constant energy use, even during sleep. Choice A is correct because it identifies breathing (movement of respiratory muscles), heartbeat (movement of heart muscle), and staying warm (temperature regulation) as continuous energy uses during rest. Choice B fails because it claims dogs can make their own food, when only plants can perform photosynthesis - dogs must eat food to get energy for all life processes. To help students understand: Have students feel their pulse and breathing while sitting still - 'Even when you think you're not moving, your heart and lungs never stop working, using energy every second.' Emphasize that being alive requires constant energy use: 'Your body is like a car with the engine always running, using fuel (food energy) even when parked (sleeping).'

Question 19

A tadpole eats algae; how does it use energy from that food?

  1. swim, grow bigger, and change into a frog (correct answer)
  2. make its own food from sunlight and water
  3. only move, not for growth or body changes
  4. store all energy and never use it
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth, such as building new cells and tissues to grow bigger, change into a frog, heal, and replace old cells; (2) Movement, including swimming, breathing, heartbeat, digestion, and blinking; (3) Warmth, maintaining body temperature even in amphibians during metamorphosis. Choice A is correct because it accurately identifies swim, grow bigger, and change into a frog as uses requiring food energy, showing the tadpole transforms algae energy for growth and movement (noting amphibians may not emphasize warmth as much but still use energy for body processes). Choice B fails because it suggests animals make their own food from sunlight and water, a plant process; animals eat for energy in growth, movement, and development. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth,' list tadpole examples like metamorphosis for growth, swimming for movement, and basic warmth; emphasize all life changes need food energy; watch for confusions like only movement or animals photosynthesizing.

Question 20

A robin eats a worm; how does the robin use energy from food?​

  1. fly, grow feathers, and stay warm (correct answer)
  2. turn sunlight into food by photosynthesis
  3. only sing songs, not for warmth or growth
  4. give its energy to plants in the forest
Explanation: This question tests understanding of how animals use energy from food for growth, movement, and warmth (NGSS 5-PS3-1). Students must recognize that all animal activities require energy that comes from the food they eat. Animals use the energy from food they eat in three main ways: (1) Growth, such as building new cells and tissues to grow bigger, develop body parts like feathers, heal, and replace old cells; (2) Movement, including flying, breathing, heartbeat, digestion, and blinking; (3) Warmth, maintaining constant body temperature in birds by generating heat. Choice A is correct because it accurately identifies fly, grow feathers, and stay warm as the main uses of food energy in animals, demonstrating the robin uses worm energy for multiple purposes at once. Choice B fails because it states animals turn sunlight into food by photosynthesis, when only plants do this; animals cannot make food and must eat to get energy for growth, movement, and warmth. To help students understand how animals use energy: Create three categories on the board labeled 'Growth,' 'Movement,' and 'Warmth,' brainstorm bird examples like growing feathers for growth, flying for movement, and heat generation for warmth; emphasize all use food energy, even at rest; watch for confusions like animals producing energy or only one activity needing it.
