This Photosynthesis & CO2-O2 lesson was created for my 5th grade students, but it can be adapted as an intro to 4th grade or a review for 6th.
The review lesson connects Photosynthesis and the Carbon Dioxide-Oxygen Cycle and includes:
• manipulatives used for both concepts
• student pages for both concepts
• teacher keys and diagrams
I used this lesson to review the two topics in the Life Science Unit, and most importantly to make the connection to both. It makes a great tutoring or small group lesson. Be sure to copy the manipulatives on card stock.
I hope you and your students enjoy! Happy teaching!
