The Hour of Code is a global movement reaching tens of millions of students in 180+ countries. Anyone, anywhere can organize an Hour of Code event. No experience needed. Ages 4 to 104.
On March 14, 2018, the first #hourofcode event was lead by Mr. Amir in Play2Learn Education Edgemont Community Classroom. There were over 30 kids involved in this one hour coding activities. We can see how kids love coding and learning programming.
The topic of today is the energy transformation study using the boat pulley model. The students first built a mimic boat pulley model, then they conducted the experiment to test the energy consumption for load lifting. The experiment also includes the energy efficiency calculations of load lifting for the boat pulley, which is derived using the useful energy divided by the total energy consumption. Energy efficiency is one of the most essential physical and engineering concepts. It’s the key to understand many modern industrial system designs.
The STEM behind this class is the energy transformation between the electrical and potential energy as well as the energy efficiency. The experiment involves some math that is beyond some students’ ability, thus we simplified based on their mathematical levels. All the students finished the model buildings. More importantly, they all finished the experiment section and conducted the energy efficiency calculations. They learned knowledge and enjoyed the class.
The model building of today is the Walker. The students built a big cricket (a legged robot) to learn the basic knowledge of mechanical balance and friction. The legged robot is comprised of four legs with a wheel at each end, it can walk with different leg lengths. The walk motions are power by one electrical motor. The motor axis kinetics are transferred by a worm gear, and then to the legs. The STEM information behind this section is the basic mechanical mechanism and concepts including a worm gear, static friction and geometrical balance of machines. All students finished the model and conducted tests by changing the legs’ length to compare the walking speed and balance.
The students had a lot of fun after finishing the model building and lab tests. They used their robot as battle robots to compete with each other. Even though we are still trying to teach the students more STEM, it works better if we can teach them with fun.
This class went extremely well. The kids understood the Balance and the concepts we were working with very quickly. The in-class assignments were also done with relative ease. The concepts included mass, simple dynamics, and weight shift. Next week we will be working on a new project that is going to be slightly more complex than the previous week, as the concepts are supposed to build on each other until the end of the semester.
Phase III is the highest level of class in Play2Learn Education Lego Challenge Program. In the next 8 weeks, different energy form transformations will be discussed including energy experiments between kinematic energy and potential energy, electrical energy and kinematic energy, heat (light) energy and electrical energy.
The class started with the explanation of the basic skills to use the power meter and motors. The class follows with building a hand generator that transfers kinematic energy to electrical energy. The kinematic energy is generated by the students’ hand. The generated energy was stored in the power meter. The class was intense because the students need to learn the principle model knowledge and finish the hand generator model building. However, after the first class, they gained a good understanding of the power meter and motors which laid a solid ground for the following classes.
Phase II is the middle-level class of Play2Learn Education Lego Challenge Program. In the next 8 weeks, the students will have good opportunities to learn and practice the basic mechanical mechanisms including lever, wheel and axle, pulley, wedge and screw.
We started the Phase II by the LEGO Digital Designer (LDD) class. The main reason is we would like to teach the student the skills to use the LDD so they can have more time to do their own Lego designs. The LDD program allows users to build models using virtual Lego bricks, in a computer-aided design like manner. We taught the students the basic skills to use LDD, such as how to pick parts, how to save the file, how to rotate part, etc. The students get familiar enough with it after some instructions and practice. They were then requested to build a screw model in LDD following a step by step booklet. The STEM information behind this section is the computer-aided designs, which is common in industry designs every day. All students got a good practice with LDD, and they were ready to design their customized models.

Today we had a mostly free build period as the class went wild with their ideas in Lego digital designer. The ideas and designs presented by the students were all excellent and they built some truly impressive creations. As for the free build what ended up happening is that most of the students attempted to build a massive wall across the room. The kids definitely seemed to have fun in phase 2 and we hope to see them again in phase 3!
Today was a free build period and most of the class built cars, all with different propulsion systems. The kids appeared to have had a lot of fun during the semester and clearly demonstrated their knowledge in the free build. Thank you all for the wonderful semester, hope to see you all in Phase 2!
The first class went according to plan. It was a great way for the kids to understand the conduct of the class and also get to know each other. Everyone was able to finish their project and enjoy competing against each other at the end. The kids also made sure to enjoy their time in class which is important as well, as it will encourage deeper learning. Next week we will be working with more projects in the class that are similar to what was worked on Wednesday, but slightly more complicated.
