hammer time?

Hello everyone, welcome to another day of LEGO challenge.  It is the third class of the semester and good to see everyone showed up.  This week, we build a hammer.  Yes, we are going to knock something hard.  The building process is not hard, most of the students finished right after half of the class time and go on knocking.  For the experiment, we are going to test the friction on different gears.  First we test it out by hands and give it a rating of how much force we use to push an axle through it from 1-4.  Then we use our hammer to count how many time it takes to knock the axle through.  At this point, we have an idea of how much friction it has on each gears.  The second part of the experiment is to test does the angles, which is how much the hammer lift, effect the force to knock? This would be their homework and I’m willing to discuss about it on the following week. 

Communication ECA Phase 1 Class 2: Hammer Machine 20200115

Last class we built a hammer machine! This machine used a crank and camshaft to move the hammer up and down allowing us to push out nail down with minimum effort! Everyone did great  with so many moving pieces! Its really important though to make sure we’re checking that we have the right size piece so the build works properly. See you all soon for our next project!

Communication ECA Phase 1 Class 3: Hammer Machine 20190925

Hello! Last class we built a hammer and attached it to a cam shaft. Using a crank we were able to move the hammer up and down hitting axles (nails) through different gears. As the experiment continued we noticed that different gears were tighter creating more friction around the axle (nail). Later we expanded and attempted to add more weight on to our hammer to increase its efficiency! I was very impressed with everyone’s understanding on the cam shaft and its different positions! I look forward to next week when we’ll be building a sweeper like the ones we see in calgary to pick up rocks!

PBP Phase 1 Week 3: Power Hammer

Today we built the Power hammer and learned precisely why it is called that, We also learned a bit about friction in joints. The kids really liked this project (for obvious reasons) and a few of the students did exceptionally. The topic for this friday is the Sweeper. Hopefully the kids will be able to learn to clean up a bit better.

ECA Phase I Week 3 201901: Hammer

We learn friction via experimenting on Hammer-Hit-Needle. This is an excellent experiment to watch different gears with axles have different friction.

Feeling the friction by pulling the axle out of the gear, ranking them by the force we used; then use the experiment Hammer-Hit-Needle to verify if what we felt is exactly same or not.

The class goes smoothly and kids cooperate with each other. Team spirit is always the key to win!

Hammer

Today we built a hammer. This build taught students about friction and force. Depending on the tightness of each gear the friction is different. The students discovered that larger gears had a higher friction than the smaller gears. The force of the hammer was able to push the axle into the gear as well. Next week I would really appreciate it if students would check if each piece was inside their kit to make sure no one will have trouble finding anything.

PBP Phase 1: Class 2: Power Hammer

Today we built the Power Hammer and learned about force and friction.  The students seemed to have enjoyed the activity with some making incredible modifications in order to give more impact force for their hammers. To all parents please make sure that all the students arrive on time and clean up thoroughly after.

Communication ECA Phase I Class 3: The Hammer

The kids were able to do really well in the last class and also enjoyed their time. Even though some of the children did notice that this project was a little more challenging than the ones they had worked on in the previous classes, they were able to keep up their pace and finish their projects. The concepts this class focused on were force, weight, and friction. The kids got to grasp these material and practice them with their in-class assignments. Next week there won’t be any classes as the kids will want to enjoy their spring break. I look forward to seeing everyone again on April 4.

PBP Phase 1: Class 3: Power Hammer

This week we built the Power Hammer in order to understand the principles of Friction as well as Potential Energy. The students seemed to have enjoyed the activity despite a few mix ups.  In the next class we will be building a car that’s powered by a flywheel. All the students are well behaved.

Communication ECA Phase I 20180124 The Hammer

The hammer turned out to be a fun project. Although this class was more difficult than the previous classes, everyone was able to finish their work and fully understand what they were working on. The kids also worked on their class assignments and did the experiments at the end of the class. We really do understand that the classes are extremely fun and entertaining, but we ask the children to make sure their work is done before 8 o’clock so they still have enough time for putting their pieces in their boxes before the class is finished. Next week the kids will be working on The Sweeper which is another interesting project.
