This worksheet was designed for freshman level biology because I found their very old textbook was not written in a way that made photosynthesis easy to understand. Students read short text passages and then color images to help them relate the textual information with the graphic. They color an image of a leaf with outlines the reactants and products and then color a chloroplast which includes stacks of thylakoids where the reaction takes place. Text and coloring image are followed by specific questions that students can answer by carefully reading the passages and examining the image. (Their textbook is not needed for this exercise.) Students will need to have some knowledge of cellular respiration to answer a question about the relationship between photosynthesis and respiration. I also have a coloring / reading worksheet for cellular respiration.
If you are looking for a hands-on experience with photosynthesis, Carolina sells a kit to make algae beads that react to light. This does require some advance preparation. Students can also do a photosynthesis virtual lab which requires no set-up or materials.
This worksheet does not go into detail about the light dependent and light independent reactions, though I do have a coloring worksheet that covers these reactions that I use with the second year biology students.
Grade Level: 8-10
Time Required: 25-30 minutes
HS-LS1-5 Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.
HS-LS1-6 Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
