Now describe your own invention.
Step 1

A smart backpack
Step 2
Write Write about your invention. You can also draw a picture of it.
My Invention — A Smart Backpack
My invention is a smart backpack. It’s really good, helpful and easy to use.
The backpack has a nice look. It has a big part to put things and some small pockets. It’s made of light and waterproof material. There’s a little screen on one side and a place to charge phones on the other.
It can sort your stuff. When you put books, notebooks and pens in it, it uses small tools to keep them tidy. It can tell you how heavy the backpack is. If it’s too heavy, it will send a message to your phone.
One possible version
There’s a solar panel on top. So, it can charge your phone when there’s sun. You can find your things easily. No more looking for things everywhere!
The weight-telling part helps you not carry too much. This is good for your back. With solar charging, you don’t need to worry about your phone dying when you’re out.
For students, it makes school life easier. They can carry books well and keep phones charged for study or fun. For travelers, it’s great. They can keep things tidy, know the weight to avoid back pain, and charge things when traveling.
It’s also good for the earth. Solar charging means we use less extra power.
