Science worksheet for Grade 3 students focusing on batteries and their use in everyday devices.

Let’s solve this step by step.

Part 1: Drag and drop the words to the blanks.

We have these words to choose from:
- carry
- battery
- recharged
- replaced
- run down

Now, let’s look at each sentence:

1. A __________ is a device which gives power to devices.
→ This is defining what a “battery” is. So, answer = battery

2. We can __________ batteries with us.
→ We take batteries along — we “carry” them. Answer = carry

3. After using batteries for some time, they eventually __________.
→ When batteries lose power, we say they “run down”. Answer = run down

4. Old batteries should be __________ with new ones.
→ You take out old ones and put in new ones — that’s “replaced”. Answer = replaced

5. Some batteries can be __________.
→ Some batteries (like rechargeable ones) can be used again after charging — so “recharged”. Answer = recharged

✔ All words are used once. Perfect.

Part 2: Click on the devices that use batteries to work.

Look at each item:

- Remote control → ✔ Uses batteries
- Microwave → ✘ Plugs into wall outlet
- Iron → ✘ Plugs into wall outlet
- TV → ✘ Usually plugs in (unless portable, but standard TVs don’t use batteries)
- RC car + remote → ✔ Both usually use batteries
- Alarm clock → ✔ Many use batteries (especially if not plugged in)
- Flashlight → ✔ Definitely uses batteries
- Rice cooker → ✘ Plugs into wall
- Smartphone → ✔ Has built-in rechargeable battery

So, devices that use batteries:
→ Remote control
→ RC car and its remote
→ Alarm clock
→ Flashlight
→ Smartphone

*(Note: Some alarm clocks plug in, but many also have battery backup or run on batteries — since it’s shown as a classic twin-bell alarm clock, it likely uses batteries. Same with smartphone — definitely has a battery.)*

Final Answer:

Fill-in-the-blanks:
1. battery
2. carry
3. run down
4. replaced
5. recharged

Devices that use batteries:
- Remote control
- RC car and remote
- Alarm clock
- Flashlight
- Smartphone
