Plants make their own food using energy from the sun. The food plants make (and eat) is called glucose. What particles do you see in glucose? (carbon, hydrogen, oxygen) Knowing that matter can neither be created or destroyed, where might the particles in glucose have come from? As a seed grows, where does the plant's matter come from? Grade 5 students make a claim: Plant matter comes from A) soil, B) water, C) air, or D) sunlight. Students investigate photosynthesis and explain how plants make the air we breathe. It's why we plant a tree to help the earth!
