When you bend a glow stick, a small chamber inside breaks, releasing a substance that reacts with other substances inside the glow stick. The reaction that takes place causes the glow stick to glow. What energy transformation takes place when a glow stick is lit?
sound energy = light energy
chemical energy = light energy
thermal energy = light energy
electrical energy = light energy
B-lake rubs his hands together quickly on a winter evening. Why does rubbing your hands together help warm them?
heat is absorbed for the air by the hands
heat is generated by mechanical energy being converted to heat energy
heat is conducted between two hands when they are touching
heat is transferred back and forth between two hands when they are close together

Colin decided to investigate soil erosion by water. He measured rates of erosion on model hills made of soil, rock, and sand. What was the test (independent) variable?
the rate of erosion on the hills
the steepness of the model hillsides
the amount of water sprayed onto the hills
the type of material used to construct the model hills
What does water have to do in a cell to maintain homeostasis?
the cell is gaining more water than it loses
the cell is losing more water than it gains
the cell is losing the same volume of water that it gains
the cell is not allowing water to enter or leave the cell

A student is drawing a model of the carbon cycle. Which caption should she include to explain how herbivores contribute to the carbon cycle from the food they eat?
Herbivores eat plants, producing carbon dioxide during cellular respiration that is released into the atmosphere.
Herbivores eat plants, producing carbon dioxide during photosynthesis that is released into the atmosphere.
Herbivores use carbon dioxide from the atmosphere to produce oxygen during cellular respiration.
Herbivores use oxygen from the atmosphere to produce carbon dioxide during photosynthesis.
Which of the following correctly describes homeostasis?
using stored energy
creating copies of cells
making large complex molecules
maintaining a stable internal environment
Sara is learning about photosynthesis and cellular respiration in her science class. Which statement can Sara write that BEST explains the relationship between these two processes?
Plants that use photosynthesis to produce food while animals must consume their food.
The chemical reactions of photosynthesis and cellular respiration could not take place without each other.
When cells do not have enough energy for respiration they rely on fermentation.
Photosynthesis and cellular respiration are both chemical processes.
One living plant leaf, still attached to the plant, is placed into a cup and covered with water. A light source is placed so that it shines into the cup on the leaf. In moments, bubbles appear on the surface of the leaf. Which statement explains what causes the bubbles to appear?
Photosynthesis is occurring and the bubbles of carbon dioxide gas are being released by the plant.
Photosynthesis is occurring and bubbles of oxygen gas are being released by the surrounding area and absorbed into the plant.
Photosynthesis is occurring and bubble of oxygen gas are being released from the plant.
Photosynthesis is occurring and bubbles of air are entering the water from the area around the plant.
