Educational worksheet on forms of energy featuring diagrams of energy transformations and a word bank for students to fill in the blanks.

To solve the problem, we need to identify the forms of energy involved in each transformation depicted in the diagrams. Let's analyze each diagram step by step:

Diagram 1: Apple → Person Riding a Bicycle

- Apple: The apple contains Chemical Energy (from the sugars and other chemicals it stores).
- Person Riding a Bicycle: When the person eats the apple, the chemical energy is converted into Mechanical Energy as they ride the bicycle.

So, the completed diagram is:
- Apple → Chemical Energy → Mechanical Energy

Diagram 2: Battery → Flashlight

- Battery: A battery stores Chemical Energy.
- Flashlight: When the battery is connected to the flashlight, the chemical energy is converted into Electrical Energy, which then produces Light Energy.

So, the completed diagram is:
- Battery → Chemical Energy → Electrical Energy → Light Energy

Diagram 3: Plug → Lamp

- Plug: The plug connects to an electrical outlet, providing Electrical Energy.
- Lamp: The electrical energy is converted into Light Energy when the lamp is turned on.

So, the completed diagram is:
- Plug → Electrical Energy → Light Energy

Diagram 4: Drill → Car

- Drill: The drill uses Electrical Energy from a power source or battery.
- Car: If the car is being charged or powered by an electric motor, the electrical energy is converted into Mechanical Energy to move the car.

So, the completed diagram is:
- Drill → Electrical Energy → Mechanical Energy

Diagram 5: Sun → Plant

- Sun: The sun emits Light Energy.
- Plant: Plants use light energy in the process of photosynthesis to produce Chemical Energy (stored in glucose).

So, the completed diagram is:
- Sun → Light Energy → Chemical Energy

Diagram 6: Plug → Toaster

- Plug: The plug connects to an electrical outlet, providing Electrical Energy.
- Toaster: The electrical energy is converted into Heat Energy when the toaster is used to toast bread.

So, the completed diagram is:
- Plug → Electrical Energy → Heat Energy

Final Answer:

\[
\boxed{
\begin{array}{ccc}
\text{Apple} & \rightarrow & \text{Chemical Energy} \rightarrow \text{Mechanical Energy} \\
