windmill

This week’s class, we introduce the conservation of energy. We build a windmill which will transfer wind energy to rotational energy and use rotational energy to lift heavy blocks. It just gives them an idea of use renewable energy to save slow down climate changes. It was not super challenging to build the windmill but to line up the fans properly and have the block system on the right side caught them off guard. Once they realized it, the experiment went smoothly, and big thank shut out to Daniel who was a fantastic helper that day.

Communication ECA Phase 2 Class 2: Fan Powered Windmill 20200115

In our last phase 2 class we all worked on a windmill! I brought a fan into the class to power them! At the back was a rope attached to a weight and because of our complex gears cluster in the middle, the windmill was able to raise and lower the weight using just the fan! Everyone had alot of fun but there were some struggles. Its important to make sure we all ask for help if we get stuck!

PBP Phase II Combined Class 2: Windmill

Today we built the Windmill and learned a little bit on how wind power was used. The kids had fun testing their windmills using using a fan that provided the wind with nearly all of them finishing on time. The topic for next week is the dragster. Please be prepared. Additionally ask the children to clean up a bit better as some parts were found on the floor.

Communication ECA Phase II Class 3: The Windmill 20180321

The topic of today is the windmill. The students built a windmill to learn the energy conversions between wild energy and rotational energy by the blade mechanism. Windmills were used to mill grain, pump water in the history, but the majority of modern windmills take the form of wind turbines used to generate electricity, or wind pumps used to pump water. In the class, we used a weight as water to mimic the pumping water process. The STEM information behind this section is the energy transformation as well as force and motion concepts.

All students finished the model and conducted tests with a different level, they enjoyed the class. The ability level of the students vary, thus it needs to arrange them wisely to make sure all of them can at least finish the model building part.

PBP Phase 2: Class 2: Windmill

I apologise for the late Classminutes as there were some technical difficulties on my end.

Last class the students built a Windmill in order to learn the principles of wind energy and the effect of surface area on the power output. The students were able to finish all the models on time, some did need help however, and help cleaning up was much appreciated. Avery is very adept at group work however some groups are a bit difficult to make work. Yuan appears to be very good with the kits and demonstrates an good understanding of the material. The students seemed to like the Windmill alot to the point where the fan providing the wind was overcrowded.

On friday the 26th we will be building the Walker.
Apologies for the late response.
