Grade 4 - Worksheets - Science - Free Printable

It looks like you've uploaded a Grade 4 Science worksheet from the Ministry of Education's Primary Engagement Programme, focusing on the topic: "Energy: Forms of Energy and Its Uses". The worksheet includes definitions, sources of energy, and images illustrating different types of energy.

Since no specific question is written on the worksheet (such as "Identify the energy source in each picture" or "Define energy"), I will assume that your task is to complete the worksheet based on the content provided — likely by filling in missing information or answering implied questions.

Let’s go through the worksheet and provide a completed version with explanations:

🔹 Definition:

> Energy is the ability to do work; another word for energy is power. Energy makes things move. It makes machines work. Energy also makes living things grow.

✔ This definition is already correct and complete.

🔹 Sources of Energy

Humans use energy from many different sources.

- They utilize the power of wind, water, and sunlight.
- Plants and animals provide energy in the form of food.
- People also burn oil and natural gas for energy.

✔ These bullet points are accurate and well-explained.

🔹 Images and Their Energy Sources (Labeling/Explanation)

Now, let's identify and explain each image shown in the worksheet:

1. Wind Energy
- 🌬️ Image: Wind turbines spinning in a field
- 🔍 Explanation: This shows wind energy, which uses moving air (wind) to turn turbine blades and generate electricity. It’s a clean, renewable energy source.

2. Hydropower (Water Energy)
- 💧 Image: Water flowing through a dam
- 🔍 Explanation: This is hydropower, where the movement of water (from rivers or dams) turns turbines to produce electricity. Also renewable.

3. Solar Energy (from the sun)
- ☀️ Image: Solar panels on a roof
- 🔍 Explanation: Solar energy captures sunlight using solar panels to generate electricity. It’s renewable and widely used in homes and industries.

4. Fossil Fuel (from oil)
- ⛽ Image: A person pumping fuel into a car
- 🔍 Explanation: This represents fossil fuels (like petrol or gasoline), derived from ancient plants and animals buried underground. They are non-renewable and release carbon dioxide when burned.

5. Cooking Gas (Natural Gas)
- 🔥 Image: Blue flame from a stove burner
- 🔍 Explanation: This is natural gas, often used for cooking and heating. It burns cleaner than coal but still comes from fossil fuels and is non-renewable.

6. Foods to Give You Energy!
- 🍎🥦🥩 Image: Fruits, vegetables, meat, bread, etc.
- 🔍 Explanation: Food provides chemical energy that our bodies use to grow, move, and function. This is biological energy from plants and animals.

✔ Summary Table (Optional – can be added to the worksheet)

| Energy Source | Type | Renewable? | Example Use |
|----------------------|------------------|------------|----------------------------------|
| Wind Energy | Renewable | Yes | Electricity generation |
| Hydropower | Renewable | Yes | Electricity from dams |
| Solar Energy | Renewable | Yes | Powering homes, solar calculators |
| Fossil Fuels (Oil) | Non-renewable | No | Fuel for cars, planes |
| Natural Gas | Non-renewable | No | Cooking, heating homes |
| Food (Chemical Energy)| Biological | Yes* | Body functions, movement |

> *Note: While food comes from renewable sources (plants/animals), it depends on sustainable farming practices.*

📝 Final Notes for Students:

- Renewable energy sources can be replenished naturally (sun, wind, water).
- Non-renewable energy sources take millions of years to form (oil, gas, coal).
- Using renewable energy helps protect the environment and reduce pollution.

✔ How to Use This Worksheet:

If this is a student activity, they should:
1. Write their name and date.
2. Read the definition and understand what energy means.
3. Match the pictures to the correct energy source.
4. Label or write short descriptions under each image.
5. Answer any additional questions if given (e.g., “Which energy sources are renewable?”).
