PBP Phase 1: Class 3: Flywheel Car

Today we built a flywheel powered car that the students raced for distance. Most of the students did not have a problem building the model however some got confused between different models in the booklet. The kids very much enjoyed this model, with some modifying it extensively. Please help the kids organize the kits and disassemble all the parts

Communication ECA Phase III Class 5: Pneumatics: Principal Model 20180404

The class of today is the principal model of pneumatics system. It’s the first section of the following four pneumatics system study. The main purpose of the class is to learn the basic knowledge of the pneumatics parts. In this section, one model consisting all key important pneumatics parts was built. The model consists components of cylinders, pumps, the air valve, the air tank, and the manometer. With the help of the model they built, the students learned the design philosophy and working principles of all these parts, which built a solid ground for the next following advanced pneumatic application models.

The STEM information behind this section is the pneumatic systems including the cylinder, tubes, and the air pressure measurement instruments. All the students followed the tutor instructions and finished the designed model experiments.

Communication ECA Phase II Class 5: Tower Crane 20180404

The topic of today is the Tower Crane. A crane is generally equipped with ropes or chains that can be used both to lift or lower loads and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The device uses one or more pulleys to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials, and in the manufacturing industry for the assembling of heavy equipment.

Two students first built three models with different pulley systems, then they conducted loads lifting experiments by using the built models. The speed and capacity of three tower crane models were compared. It’s clear to the students the crane who could lift heavier load had a lower speed. The STEM information behind this section is the mechanical advantage of pulley mechanisms. All students finished the model and experiments, they enjoyed the class.

ECA Phase I Class 5: Fly Wheeler

I am more and more happy to see the children developing their enthusiasm and skill in the class every week. At this week’s class once again everyone was able to finish their work and took the time to play around with their project at the end of the class. Also, almost no one had any difficulty understanding and doing their in-class assignments. The Fly Wheeler was a small piece that gave the kids some practice on concepts such as velocity, momentum, and inertia. Aside from making the class more fun, having a hands-on approach is also more educational since it allows them to directly experiment with what they are learning. Overall, I am very satisfied with the conduct of the class and look forward to seeing everyone next week.
