Simplify the Calvin Cycle and make learning fun, especially for kinesthetic learners! Students often become overwhelmed by the multiple steps and complex names of the Calvin Cycle. Help your students focus on the Cross Cutting Concept of matter and energy flow by deemphasizing names and demonstrating how the carbon atoms and high energy or “excited” electrons move through each step of the process. This activity was created to allow your students to explore the idea of the conservation of matter and energy as it flows through the process of photosynthesis. Powerpoint slides with pictures of each model will guide your students through the modeling process. While the Calvin Cycle can seem abstract and complex to the average biology student, this activity simplifies the process and helps the student trace where the atoms are moving and how energy is transferred in the process. By saying that this model is simplified, it only looks at how carbon atoms and energy, transferred by high energy electrons and hydrogen is moved through the cycle. Oxygen atoms are purposefully ignored to allow students to focus on the conservation of energy and matter. This will allow your students to meet NGSS-HS-LS1-5 “Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy” (NGSS Lead States, 2013), focusing in on the Cross Cutting Concept of matter and energy flow and the Science and Engineering Practice of developing and using models. You will need pastel colored marshmallows (yellow, pink, and blue are used in the pictures in the slides) and toothpicks for this activity. Powerpoint slides and a teacher’s guide are included.

The Calvin Cycle is such a challenging thing to teach because there are so many details. Some teachers simply skip over the details and just give students the net reaction to recite and regurgitate. I have taught it many times and I think the details are what make respiration (and biology in general) beautiful to understand. There are a few key learning goals I have for my students when they study the Calvin Cycle. This is an enzymatic process and the most important enzyme here is RuBisCO. This enzyme is super special because it can “fix” carbon from the air and very few other enzymes in nature can do this. I put a lot of focus on this enzyme and I don’t mention the other enzyme names involved, but I do tell students that all of the reactions use enzymes. The Calvin Cycle is broken down into several steps but the most important part when following the process is to watch how many carbons are in each step. Because of the way the Calvin Cycle works, I like to show “3 rotations” of the cycle at once, so students can see that 3 carbons go in (as carbon dioxide) and 3 carbons leave (in G3P). If you show only one ribulose bisphosphate at once, it is really hard for students to see that. With this activity, you can copy the cut-out sheets on different colored paper if you would like, to make their charts colorful. There are two question and reading pages. These works best if students read and answer the questions one section at a time. They may enjoy working in groups. I have included 2 versions of the activity: 1 version shows only the carbon atoms in each molecule. 1 version shows the carbon and oxygen atoms in each molecule. Carbons are shown as black circles and oxygens are shown as white circles. Included in a money-saving bundle!

RuBP oxygenase-carboxylase (rubisco), a key enzyme in photosynthesis, is the molecular equivalent of a good friend with a bad habit. In the process of carbon fixation, rubisco incorporates carbon dioxide (\text{CO}_2CO2) into an organic molecule during the first stage of the Calvin cycle. Rubisco is so important to plants that it makes up 30\\%%30%% or more of the soluble protein in a typical plant leaf^11. But rubisco also has a major flaw: instead of always using \text{CO}_2CO2 as a substrate, it sometimes picks up \text O_2O2 instead. This side reaction initiates a pathway called photorespiration, which, rather than fixing carbon, actually leads to the loss of already-fixed carbon as \text{CO}_2CO2. Photorespiration wastes energy and decreases sugar synthesis, so when rubisco initiates this pathway, it's committing a serious molecular faux pas.

This handout can be used with a lecture on photosynthesis, where students label the main features of the light-dependent reaction and the Calvin cycle.
This "BOGOnotes" handout is an excellent supplement to the BOGObiology video on Photosynthesis. This 16 page set of "BOGOnotes" features a note-taking template for Chloroplasts, the Light Dependent Reactions and the Calvin Cycle. Each diagram comes with a vocabulary word bank. It also includes 12 review questions ranging from basic facts to questions requiring in-depth analysis and critical thinking! Each activity has a corresponding answer key. The corresponding photosynthesis video tutorial is located here: https://www.youtube.com/watch?v=ZKC_aRrf1Rg I developed this method of guided note-taking for my own students when I discovered that they often needed some additional structure to guide their thinking. The Light Dependent Reactions and the Calvin Cycle of Photosynthesis are highly complex, and my students struggled to draw the reactions in a way that led to deeper understanding. Creating a structural framework was an excellent solution; students could choose to use all, some, or none of the templates and there was plenty of room in the margins for their own supplemental notes. This handout can be downloaded and filled in either as a digital file or printed as a traditional handout. Enjoy!

HS-LS2-4: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. HS-LS2-5: Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

In the last article we left photosynthesis at a point where ATP, reduced NADP, and oxygen had been produced in the light-dependent reaction. Oxygen is a waste product of photosynthesis, however the ATP and reduced NADP are used for the light-independent reaction. So although light energy isn't specifically needed for any reaction in this next
