The graph shows the speed of a bicycle over time.
Based on the graph, use the drop-down menus to make a claim about the energy of the bicycle.
The energy of the bicycle was greatest at time because the speed of the bicycle was .

Students conduct an investigation to learn about the transfer of energy from one material to another. The drawing shows their investigation setup.
On a hot day, the students place the cup with the rock in a sunny location for one hour. They then pour the room temperature water into the cup with the rock.
Use the drop-down menus to explain how the students can best observe the transfer of energy from the rock to the water.
the temperature of the water the water is poured into the cup with the rock.
A student wants to investigate the energies of two identical marbles before and after they collide. The student plans to roll the marbles toward each other across a flat surface. Changes to which two characteristics of the marbles would best show that the energy of each marble changed during and after the collision?
A solar shower is a device that people use to take showers outside. The device includes a bag and a hose with a spout. Two solar showers are filled with water and placed outside in direct sunlight. A student records the time needed for the temperature of the water in the two solar showers to increase.
Drag a form of energy into each box to show the energy change that happens in a solar shower.

Students have been asked to use Morse code to send a short message to one another. Each pair of students will stand facing away from each other at a distance of 20 feet. Which method would work best for each pair of students to send a message using Morse code?
A student looks at a tree. The student wants to model the path of light and how the tree can be seen.
Drag three statements into the list to model how the student sees the tree.

During the fall season, the belly of a male brook trout becomes bright orange. The orange belly provides some camouflage for the fish and helps attract females. Scientists have observed that males with pale-orange bellies do not attract as many females as males with bright-orange bellies.
How does the orange-belly trait most likely help brook trout?
The list describes actions that occur in the body when a person eats food.
Body Actions That Occur When a Person Eats Food
• Chewing begins to break down food in the mouth.
• Food moves into the stomach and then into the small intestine.
• Important nutrients leave the small intestine and enter the bloodstream
• The remaining materials move into the large intestine.
Which pair of body systems interact most in the processes described in the list?
A bat is observed in the night sky searching for food. The bat uses sound waves to help it find and catch flying insects.
