II. This past week in class we learned about energy. We stared off doing an assortment of handouts to assess our prior knowledge on energy. Then on Friday we started doing a lab that helped explain the transfer of energy. We also finished hook’s law lab which used springs to explain the transfer of energy. We defined the equation for work as: Energy (work) = Force• ∆X. We also defined the energy of a spring to be: E (spring) = .5 K∆X². We also used energy flow diagrams to help explain how energy transferred from one object to another and how it dissipated out to the surroundings. These energy equations made me think about some of the calculations we are did in AP chemistry. All of the calculations we do in chemistry that involve energy use Joules to measure the energy.

III. Next week in class I would like to find out more about anti-matter.
