Glen and his friends Liam and London are going sledding at a local park. There are two hills to choose from, "The Bunny Slopes," which are small hills and lots of flat surfaces, and "The Dragon," which is a steep hill and not for beginners. Glen crashes a lot, and his friends are a little nervous. If Glen were to crash into Liam and London when they were sledding, how would the crash be different on "The Bunny Slopes" than "The Dragon"?

Glen crashes a lot, and his friends are a little nervous. If Glen were to crash into Liam and London when they were sledding, how would the crash be different on "The Bunny Slopes" than "The Dragon"?
When Glen sleds down both of these hills, he will be traveling at a speed relative to the slope of the hill and gravity's pull. "The Dragon" is a much steeper and longer decline, so Glen will have more time to gain speed, which means more energy behind the collision. If Liam and London are down at the end of the slope and Glen crashes into them, the force will drive both of their sleds forward and slow or stop Glen's sled. The faster Glen is going, the more energy he has behind the impact.

Peter sets up his toy train on the railroad tracks he has in a straight line. He has a tool to measure the speed the train is traveling in centimeters/second when he pushes it to go. He set a box at the end of the ramp for the train to crash into. He measures in centimeters how far the train pushes the box and records the data in a table.
What would happen to the distance the box moves if the train increases in speed?

What would happen to the distance the box moves if the train increases in speed?
Peter’s investigation was testing how the distance a box moved would change as the speed of a toy train increased or decreased. The pattern within the data table shows that the higher the rate of the train, the further the box moved. An inference can be made that the higher something’s speed is, the more energy it has. Higher amounts of energy will result in a more significant change of motion for the object it is acting on. When the speed decreases, the distance the box moves also decreases. There is a direct relationship between speed and energy. So if he were to increase the speed of the train, the box would move a longer distance.

Mihika and Craig are racing cars down different sloped ramps. Mihika's car traveled down Slope A and Craig's traveled down Slope B. Mihika's car traveled further than Craig's. Why did her car travel further than Craig's?
Mihika and Craig are racing cars down different sloped ramps. Mihika's car traveled down Slope A and Craig's traveled down Slope B. Mihika's car traveled further than Craig's. Why did her car travel further than Craig's?
Mihika's car traveled further than Craig's and the children are wondering why this happened. Mihika has a very steep slope to her ramp which allows her toy car to travel faster and further. The more speed that the car can generate the more energy it has, this will allow the car to move further.

Mihika's car traveled further than Craig's because her ramp was steeper. This allowed her car to gain more speed and gravity to have more of a pull on the vehicle. More energy and speed will enable the car to travel faster and further. If Craig makes his ramp steeper, he will have a chance of beating Mihika in the next trial. In theory, if his ramp is steeper than Mihika's, he should be able to gain more speed and more energy so the car will travel further.

Katie and Gordon were experimenting with two bowling balls. One of the bowling balls had a mass of 6 kilograms, and the other had a mass of 4 kilograms. They compared the force needed to roll each of the balls at the same speed. They also compared how much force it took to stop the balls when the balls were rolling at the same speed.
Which conclusion did the students MOST likely arrive at after experimenting with both bowling balls?

Which conclusion did the students MOST likely arrive at after experimenting with both bowling balls?
Gordon and Katie most likely concluded that the bowling ball with the smaller mass was easiest to roll and stop than the ball with more mass. The smaller bowling ball would require less force to move and stop because it has less mass. The greater the mass, the more force is needed to make a change in motion.

An inference can be made that the higher something’s speed is, the more energy it has. Higher amounts of energy will result in a more significant change of motion for the object it is acting on. When the speed decreases, the distance the object moves also decreases. There is a direct relationship between speed and energy. If the car is placed at the top of the ramp, it will have more force exerted on it from gravity pulling it towards the ground, more room to gather speed, and the steeper incline would allow for more force to be transferred to the plastic cup, therefore, moving it a further distance.

Shakira ordered two bowling balls of the same size and type. She bought one pink ball and one orange ball. Shakira rolled each ball down the same lane at the bowling alley one time while a friend used her phone timer to measure the time it took for the balls to travel to the end of the lane. After rolling both balls down the same lane one time, they noticed that the pink ball made it to the end of the lane faster than the orange ball.
Which is the most likely reason that the pink ball moved faster than the orange ball?

Vipers, pythons, and boas have a special adaptation that allows them to process information uniquely. These snakes can detect infrared radiation from warm bodies up to a meter away. The snakes then build an image of what is emitting this heat to help the snake decide if it should attack or flee. Snakes have poor eyesight, so these pits are vital.

Echolocation is a behavior in which animals emit calls and then listen to the echoes that bounce back off of stable things in the environment. This behavior can be used to navigate and to find food or mates. Orcas, dolphins, sperm whales, and pilot whales are all creatures that use this function to gather information. They release small bursts of air from air sacs in their heads and then through their mouths. This burst of air will make a click or ringing sound. The sound will bounce off an object and return to the whale or dolphin. That information is then transferred to a centralized place (the brain) where it is processed, and the organism responds in ways that will help it survive and reproduce.

Whales and dolphins are such unique animals with this extraordinary characteristic. Echolocation is beneficial to these animals because of the depths at which some of them live. It is dark and hard to see to locate prey, so this adaptation assists them with the task. The information that is collected when the sound returns are processed in the brain. The sounds are made from stored air in the sacs and released through the mouth, but this is for sending out chirps. These animals are mammals and do not have gills. The returning information is processed through the brain.

This is a true statement. When animals receive information, it is processed through the brain. Many times the brain will store this information as a memory to help with similar situations in the future. An example we may all experience is touching something hot. If I touch a hot stove and burn my hand, I will remember in the future not to touch the hot stove again. This is a way to help ensure survival and the furthering of a species or family group.

Platypus have a "sixth-sense" that allows them to hunt underwater: electroreception. To find meals in the mud, it uses its bill to detect movements and subtle electric fields produced by its prey. Receptors on the bill detect changes in pressure and motion. Two types of receptors track the electrical signals produced by small prey when they contract their muscles. The platypus moves its head side-to-side to determine the direction and distance of its next meal by collecting and processing this sensory information. The platypus has about 40,000 of these special receptors.
Based on the passage, which of the following sentences best describes how the platypus processes an electrical signal?
