Where does the light and thermal energy given off when burns food come from?

• Light and thermal energy given off from burning food comes from the lighter used to light the food.

• Light and thermal energy given off from burning food is converted from the chemical energy stored in the food.

• Light and thermal energy given off from burning food comes from oxygen.

• Light and thermal energy given off from burning is created when food burns

How do children use food molecules to grow taller?

• Children grow taller when they use food molecules they eat to build large molecules that make up new cells.

• Children grow taller when they use the food molecules they eat to make up new cells without changing the food molecules.

• Children grow taller when they use the energy from the food molecules, but all of the molecules leave the body as waste.

• Children grow taller when they store food molecules as fat.

Tran investigated the question “How does red light affect plant growth?”

He grew one plant in white light. He grew one plant in red light. He kept everything else the same between the two plants (such as the amount of water and temperature). The plant in white light grew 3 cm in 2 weeks. The plant in red light died.

Tran made the claim that plants do not grow in red light.

Can Tran’s experiment support his claim?

Explain why his experiment can or cannot support his claim.
