In today’s class Rhea and I completed our waterwheel after struggling with the ice lolly sticks and bottle caps for a while. However, we realised that the straw we had used was not the correct size so we had to take it out and replace it with a thicker straw to allow more water to flow through so that the wheel will be able to turn more effectively.

In today’s class Rhea and I drew out separate models for how our product will look.
In the next class, we will begin working on part 1 of. our waterwheel (the turning mechanism.) We will make it out of four ice lolly sticks, a rod, five bottle caps, and part of a 1 litre bottle where the turning device will be placed. To keep it all together we will be using a glue gun to keep materials together and in place.
The techniques used during the construction process of part 1 will be using the glue gun without burning ourselves and making sure materials are in their correct places.

Rhea and I will be designing a waterwheel. The intended audience would be someone interested in waterwheels or how we show the transfer of kinetic energy to mechanical movement. The purpose of building this is to demonstrate how the paddles that are being rotated by water is showing the conversion from kinetic energy to mechanical movement.
The product is relatively simple to create and construct and would be relatively environmentally friendly because we will be using the materials available in the design labs.

Here is a video that explains how to design a simple yet efficient waterwheel model:

We will be able to adjust the size and appearances and/or aesthetics of it if we please.
