Your student maps the full picture of photosynthesis by constructing a physical model that labels all three categories: inputs (light energy, carbon dioxide, water), the process (happening in the leaves), and outputs (oxygen and glucose). The sheet walks through a five-step procedure from research to presentation, and a Think and Reflect section asks four targeted questions about where photosynthesis happens, what plants need, and why it matters to living things. An extension idea invites your student to write a short paragraph or comic strip in their own words. Suited for grades 3-6 and a strong fit for a life science or botany unit study.

As a standalone activity this photosynthesis model lab sheet takes one session to complete, but it fits naturally into a broader plant biology sequence alongside lessons on cells, chlorophyll, or the carbon cycle. A student who finishes it can articulate the difference between inputs and outputs and demonstrate understanding of how plants produce food, which makes it a solid assessment point for your homeschool science portfolio.
