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.

Light reflects from the surface of the tree.
Light enters the student's eyes.
Light from the Sun reaches the tree.
The tree absorbs light.
The tree produces its own light.
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?
