Explanation

Inventors start with a problem. Then they think of ideas. They draw their best idea. They make it and try it. If it does not work well, they make it better. Farida has a problem. Her plants on the balcony get thirsty when her family is away. She has an idea: a bottle of water with a tiny hole that lets the water drip slowly into the pot. She draws it, tries it, and fixes it. Now her plants are happy.
