Learning Intentions

• You can identify types of energy such as kinetic, potential and radiant and analyze factors that affect them by looking at their energy equations.

• You can describe exothermic and endothermic reactions and be able to identify them through word problems.

• You can describe the difference between a system and its surroundings.

Content Standards being covered:

Student can identify types of energy and explain energy changes.
179. Kinetic energy is the energy of substances in motion
180. Potential energy is the stored energy of a substance
181. Chemical energy is the potential energy stored in chemicals

HS-PS1-4. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
182. As bonds break, energy is absorbed and as bonds are formed, energy is released
183. In an exothermic reaction, the energy of the products of a reaction will be less than the energy of the reactants. Energy is released and the enthalpy is positive (increases)
184. In an endothermic reaction, the energy of the products is higher than that of the reactants. Energy was absorbed and enthalpy is a negative (decreased)
