Grade 2 science worksheet matching energy sources to their uses and identifying electricity applications at home.

Problem Description:

The task involves matching energy sources to their corresponding uses and then listing three ways electricity is used at home. The energy sources provided are:

1. Sun
2. Oil
3. Water
4. Wind
5. Wood

The uses provided as images are:

1. A fireplace (wood burning)
2. A solar panel (solar energy)
3. A dam (hydroelectric power)
4. A car (petrol/diesel fuel)
5. Wind turbines (wind energy)

Additionally, the student is asked to write three ways electricity is used at home.

Solution:

#### Step 1: Match Energy Sources to Their Uses
We need to match each energy source with its corresponding use based on common knowledge of how these resources are utilized.

1. Sun → Solar panel (Solar energy is harnessed using solar panels.)
- Match: Sun → Solar panel

2. Oil → Car (Oil is refined into petrol or diesel, which powers cars.)
- Match: Oil → Car

3. Water → Dam (Water flowing through a dam generates hydroelectric power.)
- Match: Water → Dam

4. Wind → Wind turbines (Wind energy is captured by wind turbines.)
- Match: Wind → Wind turbines

5. Wood → Fireplace (Wood is burned in fireplaces for heat.)
- Match: Wood → Fireplace

#### Final Matches:
- Sun → Solar panel
- Oil → Car
- Water → Dam
- Wind → Wind turbines
- Wood → Fireplace

#### Step 2: Write Three Ways Electricity Is Used at Home
Electricity is a versatile form of energy used in numerous ways at home. Here are three common examples:

1. Lighting: Electric lights illuminate homes, providing visibility during the day and night.
2. Appliances: Devices like refrigerators, washing machines, and ovens rely on electricity to function.
3. Electronics: Televisions, computers, and smartphones require electricity to operate.

Final Answer:

#### Matched Pairs:
- Sun → Solar panel
- Oil → Car
- Water → Dam
- Wind → Wind turbines
- Wood → Fireplace

#### Three Ways Electricity Is Used at Home:
1. Lighting
2. Appliances
3. Electronics
