So I usually talk about ATP at the beginning of my Energy in a cell unit. The kids need a solid understanding of how ATP is used in order to fully understand the significance of cellular respiration and photosynthesis. The main point that really needs to be driven home is that when the 3rd phosphate bond is broken, energy is released, and when it reattached it is stored. This lesson does NOT go into detail on how exactly it is broken or reattached. You can address that when you discuss cellular respiration or photosynthesis. For my 9th graders, I don't go into that much detail. This is part of my remote learning series, which can be used in remote learning situations, hybrid learning, flipped classrooms, or if you want to just have a digital (paper free) learning session. This is a basic activity that will walk student through how ATP is structured and how it is used in the body. While I use it in an energy unit, it could also be used in a biochemistry unit or even with the digestive system or muscular system lesson in a body systems unit. One of the skills that lesson focuses is on the student's ability to describe diagrams, which is crucial in science. The diagrams also serve as a scaffold so that students who are struggling can use them as a jumping off point. Here's the breakdown of the lesson: Students meet Jason, who is on the track team. He is getting fatigued in the middle of his runs and he doesn't know why. It is the student's job to help him figure out a plan to fix it using Biology! Students first start with their prior knowledge on why they think we eat, and why organisms like plants don't (which would be a GREAT talking point to bring up once you start covering photosynthesis) Student then make the connection between food providing us with energy. They are then walked through the structure of ATP and where the energy is stored in ATP. They will even break the bond to release energy. Then, students make the connection that when Jason is running his muscles need energy, so ATP is being broken down. ADP is then introduced, and the structure is compared to that of ATP. Student are then given a basic diagram showing how food gives the energy the body needs to reattach the third phosphate to ADP, making it ATP again! They then go back to their original response , why do we eat? They adjust their answer using what they just learned. Finally student pretend they are Jason's coach and describe to him why he is getting fatigued and how he can remedy that. Interested in this lesson? Check out my TpT store!
