1. Law of conservation of Energyusing pb&j

   BY: Symian Jenkins, Maria Suarez, & Jonathan Briggs
2. One day in the winter I wanted a pb and j. Not just any pb and j a toasted pb and j . SO I told my sister to “Make me a sandwich.” She said “No I have no energy.” I told her that she did have energy her potential energy of being lazy . So she also had energy to make me a sandwich.
3. Then her being her she ask about all energy used to make a toasted pb&j. I then said,” There is potential , kinetic , chemical , thermal , mechanical , and , a little bit of radiant energy to make it just right.”
4. She said, “how will that work?” I said,” Well you need mechanical to open the peanut and jelly.” Also to turn on the toaster. You use thermal energy because you toast the bread. Chemical because when you digest it, it gives you energy. That is also where potential energy comes in because it has the potential to give you energy.
5. Kinetic energy because when you bring it towards your mouth its moving. Radiant because whenever you turn on the toaster and open the fridge and your pretty much not gonna make it in the dark. “I never thought about it that way, but how is the energy created,” she said.
6. In replay, “ I said it is stated In the law of conservation of energy, energy isn't created nor destroyed.” “Oh Wow, I never knew it took so much energy to make a sandwich, I'm still not gonna make you one.”
