Solution:

#### 1. When we do something, we are using ________.
- Answer: Energy
- Explanation: Any action or activity requires the use of energy. Energy is the ability to do work.

#### 2. Energy can be ________ from one form to another.
- Answer: Transformed
- Explanation: Energy can change from one form to another (e.g., chemical energy to kinetic energy).

#### 3. When energy is stored, we call it ________ energy.
- Answer: Potential
- Explanation: Potential energy is stored energy due to an object's position, state, or condition (e.g., a stretched rubber band or water at the top of a hill).

#### 4. When energy is moving, we call it ________ energy.
- Answer: Kinetic
- Explanation: Kinetic energy is the energy of motion (e.g., a moving car or a rolling ball).

#### 5. Lifting the tank of water gives it ________ energy.
- Answer: Potential
- Explanation: When you lift an object, you increase its potential energy because it has the potential to fall and convert that energy into kinetic energy.

#### 6. This energy was converted into ________ energy when the water flowed down the tube.
- Answer: Kinetic
- Explanation: As the water flows down, its potential energy is converted into kinetic energy due to its motion.

#### 7. Baking soda plus vinegar gives us a chemical ________.
- Answer: Reaction
- Explanation: When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), a chemical reaction occurs, producing carbon dioxide gas.

#### 8. The cork popped off the bottle because ________ energy was changed to ________ energy.
- Answer: Chemical → Mechanical
- Explanation: The chemical reaction between baking soda and vinegar releases energy, which causes the cork to pop off due to mechanical force.

#### 9. In the bowling ball demonstration, we pull the bowling ball back and give it ________ energy.
- Answer: Potential
- Explanation: Pulling the bowling ball back increases its potential energy because it has the potential to move forward when released.

#### 10. When we release the bowling ball, we give it ________ energy.
- Answer: Kinetic
- Explanation: When the bowling ball is released, its potential energy is converted into kinetic energy as it rolls forward.

#### 11. Three substances that can make electricity are:
1. Coal
2. Natural Gas
3. Solar Panels

- Explanation:
- Coal: Used in power plants to generate electricity through combustion.
- Natural Gas: Another fossil fuel used in power plants for electricity generation.
- Solar Panels: Convert sunlight directly into electrical energy using photovoltaic cells.
