Communication ECA Phase 1 Class 4: Big Wheel Sweeper 20200122

Hello class! Hope you all enjoyed building the sweeper last week. You all did a great job with that build! We used gears to control and connect the sweeper module to the wheels so we would get movement as the vehicle moves. At the end I challenged and educated you all about how you can change your gears from 2 of the same size to a big and small gear to increase and decrease the speed of the sweeper. I’ll see you all soon!

Communication ECA Phase 2 Class 3: Simple Machines 20200122

Hey guys! Hope you’re all enjoying your week! As im sure you remember last class was abit different from what we’re all used to! Instead of building on set we all built 3-5 different machines all with different configurations and purposes. This class is very essential because it takes all the technical learning we learn with our big machines in the past and it simplifies it so we can really look at the key components. Some of the sets we built included: a crane/fishing rod, an angled weight lifter and a gear crank. 

Everyone did really awesome in this class with exploring and experimenting with these models. See you guys soon for more lego fun!

No Bricks No Problem

Sorry for arriving late.  This week we were introduced to Lego Digital Designer which we can build lego on our computer.  It is the same process as we follow the actual building steps.  Except finding the right brick is the challenge part, because we have access to all type of bricks on the computer.  We just need more time and be more patient.  On one hand, it will save parents a lot of money from buying all the bricks and instruction, the other hand is that kids can be more creative on free roam build without any instructions.  In the end, LDD is a helpful tool to save money and time and still have fun with Lego.  

Is that heavy?

Hello, it is I.  Welcom to another class of physics.  This time we used battery to power up the energy display, then use the Joules to pull a heavy block off the ground.  There are few formulas that need to remeber. F=ma=mg, W=FD(D=distance), Effiency=W/energy used*100%.  These will help the kids to do their hoemwork but I also told them in class.  It was fairly an easy project to build but needed some critical thinking to finished the expriments.  Hope they have learned somthing and had fun with it.

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 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!

Beam Balance

I appreciate everyone for coming-in in such extrem weather.  This week, we worded on a much simpler project than last time.  Almost everyone finished theirs and had been working on the expriment.  They tried to have only one object on the left side to balance with1, 2, 0r 3 on the right side.  They first predict the positions and then test it out.  It was really nice to see they were eager to learn this.  

Walker

Thank every one for coming in the cold weather.  This week we buld the walker which is powered by a battery motor; and it is the first time they work on their own to finish the project.  The whole class went really well.  The building, socializing, and learning.  The part that gets most students messed up was when they try to connect the legs to the body.  At this age, students don’t really have a good understanding of geometry.  They need to put the legs between the gaps not twisting the other way.  It would result in breaking down.  But overall, kids did a good jod on their own.

Bring Balance to the Class

First time in the North teaching and it felt great.  The classroom is unique but most importantly, I get a whole class full of future stars in it.  We built letter balance which needed group work.  Kids were showing fantastic work ethic.  What they need to improve is to follow the instruction step by step and be more patient.  After they finished, some were trying to weight heavier objects like my watch and phone which they need to rescale the levels.  It was fun to have this kind energy in my class and i hope they enjoied it as well.  Looking forward to the next class.

Communication ECA Phase 2 Class 1: Insect Wheel Walker 20200108

Last week we started our Phase 2 class. Everyone did really well! This was a very complicated build with lots of detail. The build used a rotating rod in the middle of the body to spin a small arm on either side around. This arm was connected to one front and back leg. With every rotation the legs would get pulled pushed allowing the build to walk forwards on its own. Lower down by the feet (which were wheels), we used gravity controlled locks to only allow the wheel to turn in one direction allowing for maximum grip and efficiency while walking. Like I said before, VERY complicated! Everyone did awesome! Looking forward to seeing you all next class for more fun!!!!
