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.  

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.

windmill

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.

Communication ECA Phase 2 Class 4: Charge and Drop Dragster 20200129

Hello class! I hope you all enjoyed last class! If you recall we build a dragster! We put our motor and battery pack on a tower mount for the dragster car. We were able to push a button, of our design, raising the car to connect to the motor. Then we would turn on the motor charging up the car so when we let go of the button the car would drop and shoot off!!! This build involved lots of knowledge with gears.

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!
