Cellular Respiration and Photosynthesis Equations

Students will need to fill in the blanks to explain what photosynthesis is and what cellular respiration is, what the chemical equation is for each process, and how these two processes relate to each other. Eighth graders who have a better handle on cellular respiration should be able to complete the worksheet without any help. An answer key is provided.

Cellular Respiration Storyboard

A big part of science learning is the ability to thoroughly explain a specific topic or concept. In this open-ended activity, students will need to illustrate and explain the process of cellular respiration. Students will be challenged to draw things like plant cells and animal cells with correctly labeled parts and describe what happens at each stage of cellular respiration using important vocabulary words. If a student needs more than three storyboards, simply print out multiple pages of the worksheet for them to use.

Cellular Respiration Teaching Tips

You don't have to be a biologist to teach the concept of cellular respiration. Engaging middle schools can be challenging, but with a little creativity you can make science lessons fun and memorable.

  • Use clay or play dough to illustrate the cells and the process. Take it a step further and let kids make a stop motion claymation video of cellular respiration.
  • Start with photosynthesis since kids are familiar with that from a young age, then introduce cellular respiration as the opposite of photosynthesis.
  • Incorporate hands-on experiments like the one where kids blow into a liquid solution with an indicator that changes color in the presence of carbon dioxide.
  • Cover vocabulary words first so students understand the language you'll be using when you teach this process.
  • Let kids listen to a fun cellular respiration song regularly so the process gets ingrained in their brain.

Why Use Worksheets?

Worksheets help reinforce skills from any homeschool science curriculum the student learns during the school day. They can also be used to help review for an important test or to explore concepts on a student's own time that he might not have time to study during the school day.
