Final Answer:
1. Heat energy → Sun, lava or fire emit this type of energy.
Chemical energy → It is stored in food and fuels.
Nuclear energy → It is the energy inside the nucleus of an atom.
Light energy → Sun and lightnings emit this type of energy.
Mechanical energy → It is associated with the motion and position of an object.
Electrical energy → It is associated with the presence and motion of electrical charges.
2. Properties of energy: Conservation, Transfer, Transformation, Measurability
3.
- When riding your bike… → Mechanical energy
- When you eat to have energy for later… → Chemical energy
- When you plug your TV cable into the socket… → Electrical energy
- When you turn on your car and it uses the fuel to move… → Chemical energy → Mechanical energy (but the property used is *chemical energy* as the source)
Note: For question 3, the expected answer is the *form* of energy being used initially in each case, so:
Mechanical energy, Chemical energy, Electrical energy, Chemical energy
Parent Tip: Review the logic above to help your child master the concept of worksheet on energy.
