While it is getting warm, I start collecting ideas on activities we can do outside. I found a FREE app called Curiosity School. It has instructions on making a water wheel with egg carton. We did it over the weekend. It is very easy to make and we all had a good time making it. While running the water wheel, we had opportunity to talk about how energy can change its form, and how we can change the natural energy into a form that we can use.
To make the water wheel, all you need are 1 egg carton, 2 paper plates, a skewer, scissors, stapler, and something to hold the water wheel. In the instruction, they used spools. My son made one with LEGO.
Following the video instruction in the app, first, we cut out all the little cups from the egg carton, then stapled egg carton to the edge of the paper plate. Once the edge of one plate is full, we stapled the 2nd plate to the other side of the egg carton cups. Then we push the skewer through the center of the plates and rest both ends of the skewer on the holder built with LEGO. We had a water wheel! It is very easy to do.
One thing very nice about the app is it has questions for discussion. We discussed why do we have to have the egg cartons all around the plate, what causes the wheel to spin, what was the water wheel used for in the past. We also learned couple new words, such as hydropower and renewable energy.
As a free app, I found Curiosity School is a very good science app for kids. In addition to water wheel, it has several other science experiment activities. All the activities are easy to do like water wheel. I will definitely try some other activities in the app.
