In my middle school classroom, my students come to me with very little understanding of chemical reactions. I use this lab to help students understand the difference between molecules and atoms, and to simulate the process of breaking down substances to make others which occurs in photosynthesis.
Product includes detailed teacher instructions, answer key, and all file parts are fully editable. Please download the preview to see more!
If you're interested, I have also provided a sister lab for cellular respiration.
Or get it all for a discount in my Photosynthesis and Respiration Bundle.
