Communication ECA Phase I Class 4: Amir’s Sweeper 20171004

In class the kids worked on the sweeper which is a mechanical vehicle that clears the path in front of it. It was a good exercise to help them learn the concepts of motion, force, and friction while enjoying their time playing with legos. This project was a little more challenging than the previous weeks, but everybody was able to finish in time and understood the assignments well. Next week we will be working on an interesting project called The FlyWheel.

Communication ECA Phase I Class 4: Sweeper 20171004

The students first built a Lego Sweeper, which can be used to study the gear system. They conducted the experiment to observe the sweeper rotation speed under the different gear combinations. During the experiment, the students need to change the combination of gears, so the gear ratio is different, thus the rotation speed varies. The STEM information behind this section is the gear ratio of gear systems, which can be calculated by the gear teeth number of the passive driven gear divide by the active drive gear. All the students finished the model building part and did the experiment with different level. They enjoyed this section.

Communication AmbroseU Phase I Class 4: The Sweeper 20171003

The kids worked on The Sweeper, which is a vehicle with a mechanical fan-like object attached to its front. The Sweeper clears the path in front of it as it moves, which is where the name comes from. Although this was a bit more challenging than other projects, the kids enjoyed their time and finished their projects. The Sweeper allows the children to learn how mechanical objects can be combined and manipulated in order to serve a specific role, and is thus a good engineering practice.

Next week the kids will be working on fun project called The Skywheels.

Communication PBP Center Phase I Class 3: The Hammer 20170929

Today the students built the Power Hammer and explored friction. The students all completed the build on time and, particularly the boys, loved the build. Avery demonstrates excellent spacial cognition and completes the builds faster than expected, I may be encouraging him to help other students if the need arises. Clean up was done in a quick and efficient manner, thank you to the parents that helped out.

Communication AmbroseU Phase I Class 2: The Balance 20170919

The kids had an amazing time working on The Balance, and I was happy to see that almost all of them, including our new students, understood the material well and finished on time. The Balance helps the kids understand the concept of weight measurement. Also, their homework allows them to sharpen their math skills. Next week we will be working on The Hammer and will introduce new concepts.

Communication CCS Phase I Class 3: The Hammer 20170925

Build the Lego hammer, mimic the nail drive, make a presentation. Students conducted the experiment to observe how many times are needed to hit the axis into the anvil. During the experiment, the students need to change the cam wheel position, so the potential energy of the hammer varies thus the kinetics energy. The STEM information behind this section is the energy transformation between the potential and kinetics energy as well as friction forces. All the students finished the model building part and did the experiment with different level. Did you see some rolling hammer car before? here you go! Kevin build a very unique hammer car!

Communication AmbroseU Phase I Class 3: Hammer 20170926

We build a hammer today. The hammer is used to punch the nail into the gear, by which we can feel what the friction is and how different friction in different gear. Students first built a Lego hammer, which can be used to mimic the nail drive. They conducted the experiment to observe how many times are needed to hit the axis into the anvil. During the experiment, the students need to change the cam wheel position, so the potential energy of the hammer varies thus the kinetics energy. The STEM information behind this section is the energy transformation between the potential and kinetics energy as well as friction forces. All the students finished the model building part and did the experiment with different level. They enjoyed this section. After that, some of them change their hammer to a car or some hammer car or car hammer…. LOL what a great idea!

Communication ECA Phase I Class 3: The Hammer 20170920

The kids took their time to work on The Hammer. Even though the work was more challenging than before, they still enjoyed the process and were able to finish their project. The Hammer allows them to learn about the concept of force and to do measurements with different parts, and so it was a good practice for them to learn such physical concepts. Next week we will be working on The Sweeper, which is a mechanical vehicle that lets them sweep the surface.

Communication PBPCenter Phase I Class 2: The Balance 20170922

1) Had students build a Beam Balance as well as a weight set
2) The balance was used to to teach the principles of torque and forces on a lever.
3) Most students were very happy that they got to play with the balance though some did struggle
4) Next week we will be studying friction as well as building a hammer and anvil
5) Please ask the students to do cleanup and not to hesitate to ask for help in completing their builds
