About

A ventilation fan is a simple way to stay cool indoors. The fan blows air that evaporates the moisture on our skin to cool us down. Ventilation fans are popular around the world, especially when the weather gets hot.
 

Your task

Design a battery-operated ventilation fan for use at your home. Think about how a fan can give comfort to you and your family at home. Where should your fan be? How will it work? Work on this design topic in a small team with a group of your classmates.

Follow the design steps

To design something well, do it step-by-step and use the methods from the Design Thinking for Schools website. There are four design steps. The first step is LEARN. To design something, you must first learn about it. There is much to learn on any topic, and it is always interesting. Learning will help you to understand the thing that you are designing, so you can do a good job. The second step is DRAW. Try to think of as many different ideas as you can while you draw them with pencil on paper. Keep drawing until you have some ideas that you really like. Improve your ideas and combine them into a single excellent idea. Drawing is easy and fun. Enjoy it! The third step is MAKE. Make the thing that you are designing to show your teacher and classmates. You can only tell if your idea works by making it. Improve your idea while you are making it. Making something with your hands is fun too! The fourth step is TRY. Once you have made something, you should try it to see if it works or not. You can also let someone else try it to see what they think. When you try, you will often find ways to improve your design idea. That will make you a better designer.
