An ecosystem contains grass, rabbits, snakes, and hawks. A drought causes much of the grass to die. Explain how this change could affect ALL the organisms in the food chain.
Rabbits would have less food, causing their population to decrease. Snake populations could decrease because they eat rabbits, and hawks may also decrease because there are fewer snakes and rabbits available as food.
A roller coaster car starts at the top of a steep hill, rolls downward very quickly, then slows as it climbs the next hill. Explain how potential energy, kinetic energy, and friction affect the motion of the roller coaster throughout the ride.
At the top of the hill, the roller coaster has high potential energy. As it rolls downward, potential energy changes into kinetic energy, causing the coaster to move faster. As the coaster climbs the next hill, kinetic energy decreases while potential energy increases again. Friction between the wheels and track slows the coaster down by changing some energy into heat.
