Belonging

– What groups do you belong to?

pivot city basketball club. Newtown football club. my family.

– Pick a group that you belong to discuss what the benefits are of being apart of it?

pivot city basketball club. meeting new friends. learning how to get better.

– How do the groups you belong to differ among you and your family members/ friends?

Pivot city is made up of different people from different schools but my sisters netball team is school kids only.

Term 3 Projects. Pinball Machine

In Term 3 we are doing projects. I am making a Pinball Machine with Jack and Hayder. Hayder is 3d printing some of the obstacles and Jack and I are measuring and building with the cardboard. We are using the hummingbird LEds on the backboard of our pinball machine. Here are some photos of so far.

I did some designs today of our obstacles. We going to try a rubber band slingshot to launch our ball into the course. Here is a photo of my design idea.

Today Jack brought screws and we started screwing our pinball machine. Last Lesson we made I obstacle for it. Here is all our equipment.

20 minutes later we screwed our first corner.

Here is the machine with one wall left to go.

2 hours later we have now screwed our whole pinball machine together.

 

Bloxels

This Term we are doing projects and I am doing Bloxels. Bloxels is a video game making program. In the Bloxels kit we have a board and a grid that we make our courses with. I have photos of some courses we were experimenting with. Here are some.

 

Here is a video.

This week I am doing scratch. Abhi and I made 3 games a basketball game, a monkey with bananas game and a chasey game. Here are videos of the games.

 

 

 

The Cartesian Plane / in microworlds

For the last two weeks in micro worlds, we have been experimenting with the Cartesian plane. Last Friday we had to use setpos (setpos is a command in microworlds) to draw different shapes in each corner of the screen. There is x and y. Here is a diagram explaining what I mean.

You always put x first in your command and y second. There is a positive half and a negative half of each line. The negative half is the line at the bottom and the line on the left. The positive half is on the right and on the top. If I wanted to get to where it says    -100 100, in my micro worlds I would have to type “setpos [ -100 100 ]”. In that box it is     -100 100 because it is where the negative line of the x line, and the positive line of the y line meet. The same goes for the other boxes.

 

Now I know about where on the Cartesian plane everything is, I just need to write a program using setpos and my other shape programs that I have already made. Here is a snip of my program and a picture of the task completed.

I have a trapezium in the top left corner, a square in the top right corner, a  parallelogram in the bottom left corner and a triangle in the bottom right corner.

Ev3 Block Lifting Challenge

Today we had to use the medium motor to lift a block. We had to program our robot to go forward until the ultrasonic sensor senses our block. Then our medium motor will grab the block and drive backwards until the colour sensor senses the red piece of paper. Here is my snip of the program for this task and my video of the robot completing the task.

 

Simple Machines

Simple machines teaches you about the natural forces and using them in creations. First we researched the 6 simple machines and what they do. Then we had to make them out of K’Nex. Here is a picture of my design book after I finished the task.

Then we had to use what we had learned and make a big machine using one of the simple machines. Here is a video of my pulley.

Here is a close up picture of the pulleys that is making the whole machine work. there is two pulleys because there is one on the tower and one on the box being lifted into the air.

After this the teacher let Tom and I start Lego Wedo 2.0.Then we had to do the programming for our Lego car. The teacher showed us how to Bluetooth our computer to our Lego control block. The program was easy because the Lego Wedo 2.0 software shows you how to do the program. The simple machine in this car is a wheel and axle. Here is a video of our Lego car working.

Then Tom and I decided to make our own car. We added some mods to our car like chains, a spoiler and more. Here is a video of it driving.

Now we are doing the wobble! The car wobbles around. The simple machine in this is a wheel and axle. Here is a video of our wobble car.

Then we did the sweep. The simple machine that is vital to making the sweep work is a pulley. It doesn’t really work because of the rubber band and it falls of because o the speed of the motor. Here is a video of it working.

 

After the wobble we did the revolve. It rotates a block around. The simple machines in it are wheel and axle and a pulley. Here is a video of it.

 

Now I am doing the walk. The simple machines in this are two cogs and a wheel and axle. Here is a video of the walk.

The Ultrasonic Sensor challenge

This was a tricky challenge to do because I wasn’t there at the time when the teacher explained how the ultrasonic sensor works and about it’s functions. It was hard to get my program right, so I asked my friend Tom and he helped me. The ultrasonic sensor senses objects and it senses them from a distance. We had to use the ultrasonic sensor to stay in a square of barriers with our program. The easy part was the turning of the robot in the program. I found that bit easy because I have done challenges before that require turning so I have already learnt how to do it. Here is my program and a video of my robot completing the course.
