Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms. Remember:
• Materials that mealworms use (arrows going in) are reactants in chemical changes
• Materials that mealworm produce (arrows going out) are products of chemical changes

When mealworms eat, chemical changes take place inside the mealworms. Chemical changes rearrange atoms. Bonds are broken in reactants. And new bonds are formed in the products.

Evidence of a chemical reaction includes a color or temperature change. Evidence of a chemical reaction can also be a gas or solid product made.

Level 4 responses should show potato/food arrows entering the mealworm, feces (and possibly urine) arrows leaving the mealworm and CO2 arrows leaving the mealworm.

Level 2 or 3 responses may show a variety of forms of matter without focusing specifically on molecules containing carbon atoms.

Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.

Level 4 responses should describe chemical energy moving from the potato into the mealworm and possibly chemical energy in the feces leaving the mealworm.

Level 2 or 3 responses may show a variety of forms of energy without focusing specifically on molecules containing high energy carbon bonds.
