The image appears to be a worksheet related to energy concepts, likely from a Bill Nye the Science Guy video. Below is the solution to each question, along with explanations:

---

1. When we do something, like open a door, we use _______ energy.

- Answer: Kinetic energy
- Explanation: Kinetic energy is the energy of motion. When you open a door, you are using your muscles to move, which involves kinetic energy.

---

2. Energy comes in all different ________, like sound, heat, and electricity.

- Answer: forms
- Explanation: Energy exists in various forms, such as sound energy, heat (thermal) energy, electrical energy, etc.

---

3. Energy can ________ from one form to another.

- Answer: change
- Explanation: Energy can transform from one form to another. For example, chemical energy in food can be converted into kinetic energy when you run.

---

4. When energy is stored, we call it ________ energy.

- Answer: potential
- Explanation: Potential energy is stored energy due to an object's position or state. For example, a stretched rubber band has potential energy.

---

5. When energy is moving, we call it ________ energy.

- Answer: kinetic
- Explanation: Kinetic energy is the energy of motion. When energy is actively moving (e.g., a rolling ball), it is kinetic energy.

---

6. Mixing baking soda and vinegar causes a cork to pop off because ________ energy is changed to moving energy.

- Answer: chemical
- Explanation: When baking soda and vinegar react, they release chemical energy, which can cause gases to expand and push the cork off, converting chemical energy into kinetic energy.

---

7. Energy makes things ________.

- Answer: move
- Explanation: Energy is what causes objects to move or change their state. Without energy, nothing would happen.

---

8. The kinetic energy of a swinging bowling ball will never be bigger than its ________ energy.

- Answer: potential
- Explanation: At the highest point of its swing, the bowling ball has maximum potential energy. As it swings downward, this potential energy is converted into kinetic energy. The total energy remains constant (conservation of energy), so the kinetic energy at any point cannot exceed the initial potential energy.

---

9. We can use the energy of falling water to make ________.

- Answer: electricity
- Explanation: Falling water (hydroelectric power) can be used to turn turbines, which generate electricity.

---

10. The ________ is beaming energy to the earth all day and night.

- Answer: sun
- Explanation: The sun continuously emits energy in the form of light and heat, which reaches Earth.

---

11. A ________ converts electrical energy into heat energy.

- Answer: resistor or heater
- Explanation: A resistor or heater converts electrical energy into heat energy when current flows through it.

---

12. One of the biggest sources of energy that we use is ________.

- Answer: fossil fuels (or oil, coal, natural gas)
- Explanation: Fossil fuels are a major source of energy for transportation, electricity generation, and industrial processes.

---

13. We get energy from the ________ we eat.

- Answer: food
- Explanation: Food provides chemical energy, which our bodies convert into usable energy for movement and other functions.

---

14. The energy we get from food began as ________ energy from the sun.

- Answer: light
- Explanation: Plants use sunlight (light energy) during photosynthesis to produce energy-rich molecules. This energy is then transferred up the food chain when animals eat plants or other animals.

---

15. Whenever energy is converted from one form to another, a little bit of it ends up as ________.

- Answer: heat
- Explanation: Due to the second law of thermodynamics, some energy is always lost as heat during energy conversions. This is why no energy conversion process is 100% efficient.
