Example Questions

Example Question #1 : Develop A Model Mimicking An Animal Pollinating Plants

What is pollination? Example: Pollination is an important part of the life cycle.

Possible Answers:

When a adult animal teaches a baby animal something

The transfer of pollen to create new plants

Littering or releasing chemicals into the environment

When caterpillars emerge from their cocoon

Correct answer:

The transfer of pollen to create new plants

Explanation:

Pollination is the transfer of pollen to new plants for fertilization. Bees, hummingbirds, and butterflies are just a few animals that help the pollination process. The animals go from plant to plant, spreading the pollen.

Example Question #32 : Life Science

Miranda's teacher asked them to draw a model of an animal pollinating plants. Which of the following should she draw?

Possible Answers:

Bat

All of the animals are pollinators

Bee

Butterfly

Correct answer:

All of the animals are pollinators

Explanation:

If Miranda is drawing an animal that pollinates plants, she could draw any from the list; they are all pollinators! Bats, bees, and butterflies all move from flower to flower, spreading pollen to help fertilize plants so new ones can grow.

Example Question #33 : Life Science

Hummingbirds pollinate tube-shaped flowers that have nectar and pollen. Their beak picks up pollen from one flower while they feed, and it is dropped into another flower when they move to the next plant to eat.

If humans wanted to use something that mimicked a hummingbird to pollinate their flowers, which item would be best?

Hummingbird, Flying, Feeding, Wildlife

Possible Answers:

A straw

Your hand

A spoon

A cup

Correct answer:

A straw

Explanation:

The best tool to use for mimicking a hummingbird's beak would be a straw. It is thin and can fit inside the tubular flowers to collect pollen or nectar. It could be moved easily from plant to plant for fertilization.

Example Question #34 : Life Science

Michael is creating a model of an animal that pollinates plants. He knows that while the animal stops at a flower to eat, it gets covered in pollen. The pollen sticks to the animal as it flies to the next flower. There the powder is rubbed into the flower, and new material is picked up to be spread.

Which material would be best for building his animal to transport pollen?

Possible Answers:

Paper

Felt

Tinfoil

Plastic wrap

Correct answer:

Felt

Explanation:

Michael should select felt as the material to make his animal. Felt is soft, textured, and made of cloth so the pollen dust would stick to the fabric. Plastic wrap, tinfoil, and paper are all flat and slippery, so the pollen would not stick so it can be carried around.

Example Question #35 : Life Science

Heidi is making a model of a bumblebee for her pollinator project. She knows the bee moves from plant to plant spreading pollen dust, so what it is made of is very important. The pollen has to stick to the body so it can be flown around.

Which item would be right to use to mimic the body of a bumblebee?

Possible Answers:

Cottonball

Magnet

Golf ball

Rock

Correct answer:

Cottonball

Explanation:

The body of a bumblebee gets covered in pollen as it moves from flower to flower. The dust sticks to their soft, fuzzy hair. A cotton ball would be the best choice for a material that mimics the body of a bee. It is also fuzzy and soft, so dust will stick to it. A golf ball, rock, and magnet are smooth, and pollen dust would be less likely to hold.

Example Question #36 : Life Science

What does the term mimic mean? Example: I can use a straw to mimic the beak of a hummingbird.

Possible Answers:

Extremely small or tiny

A type of plant used to season food

Imitate, copy, or impersonate

The theatrical technique of moving silently

Correct answer:

Imitate, copy, or impersonate

Explanation:

To mimic means to copy, impersonate, or imitate something or someone. If I want to mimic the behavior of a hummingbird and model a tool that is similar to its beak, the straw would be a good fit. It is a similar shape, size, and has the same function. I could copy or mimic a hummingbird's actions and collect liquid.

Example Question #41 : 2nd Grade Science

Andy's teacher asked them to draw a model of an animal pollinating plants. Which of the following should he draw?

Possible Answers:

Frog

Hummingbird

Squirrel

Sunflower

Correct answer:

Hummingbird

Explanation:

If Andy is drawing an animal that pollinates plants, he could model a hummingbird to represent the pollinator! Squirrels and frogs are not pollinators, and sunflowers are not an animal! Hummingbirds move from flower to flower, spreading pollen to help fertilize plants so new ones can grow.

Example Question #8 : Develop A Model Mimicking An Animal Pollinating Plants

Bumblebees pollinate flowers that have nectar and pollen. The pollen from one flower sticks to them while they feed, and it is dropped into another flower when they move to the next plant to eat.

If humans wanted to use something that mimicked a bumblebee to pollinate their flowers, which item would be best?

Possible Answers:

Velcro

Tape

Felt

All of the answers are correct

Correct answer:

All of the answers are correct

Explanation:

To build a model of a bumblebee, a human could select felt, velcro, or tape as the material to make the animal. Felt is soft, textured, and made of cloth so the pollen dust would stick to the fabric. Velcro is textured, and things stick to it. The tape is very sticky, and pollen would attach itself to the sticky side to be carried around. All of the answer choices are correct and could be used to model a bumblebee.

Example Question #51 : 2nd Grade Science

Hummingbirds pollinate tube-shaped flowers that have nectar and pollen. Their beak picks up pollen from one flower while they feed, and it is dropped into another flower when they move to the next plant to eat.

If humans wanted to use something that mimicked a hummingbird to pollinate their flowers, which item would be the worst?

Hummingbird, Flying, Feeding, Wildlife

Possible Answers:

Straw

Twig

Paintbrush

Sponge

Correct answer:

Sponge

Explanation:

The items that would best be used to mimic an animal pollinating a flower would be the paintbrush, twig, or the straw. They would be thin enough to fit into the flower and have the end transfer or pick up the pollen. The sponge would be too broad and would not have the right materials for the dust to stick.

 

Example Question #1 : Develop A Model Mimicking An Animal Pollinating Plants

Bats are a common pollinator of plants. Many people are afraid of bats and think they are dangerous or even attack people! Bats are very helpful to humans because they help spread pollen from plant to plant. What feature do bats have that help them get from plant to plant to spread pollen?

Possible Answers:

Wings

Ears

Stomach

Lungs

Correct answer:

Wings

Explanation:

Bats fly from plant to plant eatings fruit and picking up pollen as they move. When bats fly, they use their wings. When a bat lands on another plant, some of the powder falls off and is deposited into the stamen of the flower for reproduction. New plants are formed when this pollen is spread, and new seeds form.
