# How to Make Home Thermometers
When you are teaching young children about weather and climate, you can make the lesson more interesting and interactive by providing the kids with a hands-on activity to create. For example, show the children how to construct a home thermometer using basic household materials. This not only allows the children to better understand how thermometers work, but also helps the kids to feel more involved and excited when learning about meteorology and weather science.
