For the next three days, students will learn about leaf structure, photosynthesis, and the connection between photosynthesis and cellular respiration. Students will work in pairs to complete two worksheet packets, and those who finish early will have the opportunity to complete one or more related labs.

For day 1, the entry task called for students to answer (through writing) the following:

- What is photosynthesis?
- Why is photosynthesis important?
- Write the equation for photosynthesis (bonus: include pictures!).

Student work is pictured below:

After the share-out, students watched the Crash Course: Plant Cells video (below) which served as a refresher to plant cells and as an introduction to photosynthesis. After the video, students worked in pairs on the Photosynthesis POGIL worksheet packet.

For Day 2, students reviewed the vocabulary terms of exothermic and endothermic within the context of photosynthesis, cellular respiration, and combustion. Notes from the entry task are pictured below.

After the entry task, we watched the video about photosynthesis by Bozeman Science. Students need to know the first 4.5 minutes of content, but the remaining content (which students wanted to watch) is beyond the scope of our class. After the video, students had the remainder of class time to work on the Photosynthesis POGIL Worksheet Packet from yesterday.

For Day 3, we connected the processes of photosynthesis and cellular respiration first through our entry task and then through a Photosynthesis and Cellular Respiration POGIL worksheet packet. The entry task and white board notes answering the response are pictured below:

For students looking to dig into cellular respiration at the molecular level, the Crash Course and Bozeman Science videos are provided below:
