What happens to matter when it is burned?
Lesson Objectives...
Construct an explanation using both qualitative and quantitative data and scientific reasoning (that burning food produces energy, in the form of heat and light, and products, such as carbon dioxide and water) to describe why the mass of oil burned in an open system changes, while it stays the same in a closed system.

What we figured out this lesson...
Food goes through a chemical reaction when it is burned. This reaction provides energy.
Foods require something from the air in order to make energy.
When food reacts with air to release energy, carbon dioxide gas and water vaport are its products.
