Bionics are things that are made to help people who have trouble with their own body parts. Imagine your body is a machine, like a bike. Just like a bike needs brakes that work, our bodies need working parts to work correctly. Sometimes those parts of our bodies don't work very well, or they don't work at all. That's where bionics come in. Bionics are like extra parts for our bodies, like brakes for our bike. They help us when our own body parts don't work by replacing them or helping them to do their job. For example, someone with a disability in their arms or legs may get a bionic arm or leg to help them move around. It's like having a robot part to help you do things that you can't do on your own.
