Educational worksheet on forms of energy with diagrams illustrating energy transformations.

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: The person converts the chemical energy from the food they eat into Mechanical Energy to move 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 lamp converts the electrical energy into Light Energy.

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

Diagram 4: Drill → Car

- Drill: The drill uses Electrical Energy to operate.
- Car: The car typically runs on Chemical Energy (from gasoline or another fuel) to produce mechanical motion. However, if the drill is being used to charge a car battery, it would be converting electrical energy into chemical energy.

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

Diagram 5: Sun → Plant

- Sun: The sun emits Light Energy.
- Plant: The plant uses light energy in the process of photosynthesis to store Chemical Energy.

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 toaster converts the electrical energy into Heat Energy to toast bread.

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

Final Answer:

\[
\boxed{
\begin{array}{cc}
\text{Apple} \rightarrow \text{Chemical Energy} \rightarrow \text{Mechanical Energy} \\
\text{Battery} \rightarrow \text{Chemical Energy} \rightarrow \text{Electrical Energy} \rightarrow \text{Light Energy} \\
\text{Plug} \rightarrow \text{Electrical Energy} \rightarrow \text{Light Energy} \\
\text{Drill} \rightarrow \text{Electrical Energy} \rightarrow \text{Chemical Energy} \\
\text{Sun} \rightarrow \text{Light Energy} \rightarrow \text{Chemical Energy} \\
\text{Plug} \rightarrow \text{Electrical Energy} \rightarrow \text{Heat Energy}
\end{array}
}
