    AP physics projects for a school greenhouse

    Hi there, I'm a high school physics teacher and my school has recently built a greenhouse! I am trying to find ways that I can have my AP level physics students participate in the greenhouse project, but I'm finding that anything I can think of seems to be well beyond the scope of the course...

    Graduate Why does proton-proton fusion release energy if the products are heavier?

    Okay, I see that. Except that if we did include them, we'd get a photon on the right because there would be a free electron and the positron. Yes? This was the original source of my confusion.

    Graduate Why does proton-proton fusion release energy if the products are heavier?

    So to clarify, we're assuming the atoms are not neutral. Thank you!

    Graduate Why does proton-proton fusion release energy if the products are heavier?

    Hey, I'm sorry, could someone please help me to understand the conservation of charge and leptons that happens in the first step of Proton-Proton fusion? H(1) + H(1) --> H(2) + positron + neutrino. I think I'm missing something to do with an electron? My nucleons balance, but I'm a charge...
