I really liked the building part of the innovation day. I came over to my friends house to build the project.
Trial and error
We almost gave up after seeing our fountain and water wheel fail, meaning we had nothing to our minds until one of our work partners came up with the idea to build a dam instead of a fountain.
One part that we could’ve fixed was creating the height of the water wheel. When we drilled a hole for our axel we drilled it too low which meant we had less capacity because if the water levels increased it would create resistance in the water wheel stopping it from moving.
Pros and Cons
One of our pros was probably how we managed to find a plunger like arrow for blocking the hole to the water flow if we needed to.
One of our cons was how unstable the cans were allowing them to topple over with the smallest amount of force.
Hypothesis
Our hypothesis is that our dam invention will work along with the can pillars and axel. We have a lot of expectations due to us thinking it was a smart idea to create a dam and use a toothpick for a axel. Me and my partner really thought that coin slots were going to work for the little buckets or pillars that are normally attached to the outside of the water wheel.
Materials
Eight soda cans, one wooden axel, one yellow bucket, one clear bucket, four medium sized coin slots, one plastic bowl, sand, water, one plunger like arrow, two 2.5 litre water jugs,
Procedure
Me and my two partners worked well to finish our project and overall I think we did an amazing job! The funnest part for me was creating the water wheel or making the outside.
