Communication ECA Phase 1 Class 5: Big Wheel Balance 20200205

Last week in our phase one class we all built a balance and learnt that if we position our weights in different positions we could make one weight balance two weights! After giving them a couple challenges they began experimenting on their own and adding weights of their own. This included wheels and bars of all shapes! See you all next class for some more building fun!

Communication ECA Phase 1 Class 5: SkyRise Crane 20200205

Hello class! Im sure you all remember our build from last week! Our crane!!! We build a huge structure of a crane and attached a motor to the top for powered control. This was a very long and complex build and you all did very well! We used diagonal braces to stabilise the body of the crane. As we should know by now, triangle shapes are stronger then squares.

Next class is finally the time for our computers! So make sure you bring your laptop and the predownloaded software so we can get right into the fun!! See you all soon!!

simple machines

Hello everybody!  This week we started a whole new challenge, Simple Machine.  It was easy to build but to understander simple physics in it, is challenging.  For example, we build a lever but put the pivot point at different place to test out which point can we lift the easiest.  It was the most successful class of all because it does not matter what step we were on, but to understand how it works.  At the end of the class today, most of the students finished book 1 or close to finish book 1.  We will try to finish book 2 in the next class.  Hope all of you had fun.  

simple machine book2

Hello everyone!  Welcome to the final day of simple machines.  This time, we got complex physics machines.  For example,  we use a simple triangle shaped pusher to lift heavy weight easier.  In real life, that is how we use tools to save our energy and time.  The main differences between human and animal is that we know how to use tools to make our life easier.  At the end of the class, we finished book2 and accomplished our goal.  Next week, we are going back to build complex lego toy.  Hope you guys have enjoyed.


Hello everybody!  We are going to fight coronavirus with today’s master machinery, the sweeper!!!  It was easy to build but hard to make our sweeper more efficient.  The main focus us the gear combinations.  If we put a large gear on the motor axle and small gear on the sweep axle, that is the most efficient way.  But if we want the slowest sweep, we are going to have the large gear on the sweep axle and small gear on the motor axle.  As soon as we understand the math in it, we can have the best sweeper too sweep away all the virus.  


Hello everyone!  welcome to a whole new challenge of Pneumatic!  First thing first, what actually is that?  It is a machine that containing or operated by air or gas under pressure.  This week, we test out some different way to use pneumatics.  Use it to read pressure in kpa as one of the units to measure it.  This week is not like last few weeks.  This is more concept related.  Student just need to understand it and it has really little calculations in it.  We will keep exploring pneumatics in the following weeks and more fun to come.

Communication ECA Phase 2 Class 6: LDD 20200212

Hello phase 2 class! I hope you enjoyed designing lego on the computers for a change! Last class was meant to open your minds to many possibilities of design. For homework (if possible) youre all supposed to design your own lego set of the LDD program. During the last class you will get an opportunity to build the set in real life. Make sure you use the selection of same pieces that we have in class.

The picture is an example of the set you build in class but I’ve expanded it for greater movement. Its up to you guys to do the same! Build a design and try and use your knowledge youve learnt in class! 

Communication ECA Phase 2 Class 4: Simple Machines part2 20200127

Last week in our Phase 2 class we continued on with our simple machines! We’ve been working out of 3 booklets learning an adapting different basic models to learn how we can build efficiently. This picture i attached shows a lever that we have build and how by changing some positions we can change the difficulty it is to lift. Everyone build alot of different models during these classes and at the end I challenged the ones who had finished to create their own simple machines. Some of their ideas were quite impressive.


This week’s class, we introduce the conservation of energy.  We build a windmill which will transfer wind energy to rotational energy and use rotational energy to lift heavy blocks.  It just gives them an idea of use renewable energy to save slow down climate changes.  It was not super challenging to build the windmill but to line up the fans properly and have the block system on the right side caught them off guard.  Once they realized it, the experiment went smoothly, and big thank shut out to Daniel who was a fantastic helper that day.
