1. Match the definitions to the types of energy.
- sound energy: It's transmitted through waves when there is a vibration
- mechanical energy: It's the sum of potential and kinetic energy, and it's associated to movement and position
- chemical energy: It's stored inside matter and released by a chemical reaction
- luminous energy: It's produced by sources of light
- thermal energy: It's produced by the rise of temperature in an object
- nuclear energy: It comes from the nucleus of the atom
- electrical energy: It's produced by moving electric charges (electrons)
2. Choose the correct type of energy for each example.
- Baking a cake in the oven, when the heat of the oven is transferred to the cake so that it cooks. → thermal
- During photosynthesis, plants use the energy from the Sun to obtain their nutrients. → luminous
- Uranium is used to produce electrical energy in a power plant. → nuclear
- When we digest food, we transform their energy to obtain nutrients. → chemical
- Lightning happens when electricity is released into the atmosphere. → electrical
Parent Tip: Review the logic above to help your child master the concept of energy forms worksheet.
