Extended Investigation Terrariums
Plants can grow in a sealed glass jar without needing to be watered if they are left in sunlight. Research terrariums and make your own. Write a report about your investigation. Reference the water and carbon cycles in your report.
39.3 Chemical reactions involving carbon dioxide
Carbon dioxide is involved in two very important biological reactions. Photosynthesis, which removes carbon dioxide from the atmosphere, and respiration, which releases carbon dioxide into the atmosphere.

Photosynthesis Photosynthesis is a chemical reaction that occurs in the cells of green plants. It is a process in which light energy from the sun is converted into chemical energy in the plant. The plant uses light energy, carbon dioxide and water and produces glucose and oxygen.
Photosynthesis Word equation Carbon dioxide + Water + Light energy
