Rube Goldberg-Support Tower

This is the Rube Goldberg support tower. it supports the tube (or magik portal of magik, as I like to call it) so the tube doesn’t fall off the table. the support tower doesn’t have a purpose exept for that.

I’m going to stop talking now so I don’t give away the surprise!😉

Rube Goldberg-Train

This is the rube Goldberg machine train. The whole machine depends on this one train and marble. The train pushes the marble into the tube. Then the marble rolls down the tube (magik portal of magik, as I like to call it). Then the marble falls into a pulley. I am not talking about this anymore because I don’t want to give away the surprise!

Well I’m going to end it there.  Goodbye!😉

Rube Goldberg-Tube

this is the tube part of our rube Goldberg machine. the marble is going too roll down the magik portal of magik ( that’s what I call the tube!) and fall into a pulley, which will disturb a marble. that’s all your going to get out of me! I’m keeping it a surprise!

anyway I’m just ending it there. don’t want to spill the beans! 😉

 

 

 

robotics

today we worked on our robot. I made it with ray. we worked on programming the robot today but the robot wouldn’t do anything. I don’t know why it didn’t do anything. I think it was because the USB wouldn’t insert properly. That was annoying because I spent 2 thirds of the lesson making a really cool command. But it didn’t work and my complaining won’t do anything now. But I was upset because  it was a really cool command and I wanted to see it happen and I wanted to see what it would do.

Ray and I were pretty upset that the robot wouldn’t work but anyway I hope it will work next time so I can see what the robot will do.

GOODBYE 🙂

 

 

Today we worked on our robot. This time the commands… WORKED 😀!! I felt very pleased with myself. I have no idea how Ray felt though. The robot would go forward and go backwards but it wouldn’t stop going backwards. The robot eventually fell off the table. Next  time we have robotics we will look at our commands, and try to fix it so the robot goes forward and backwards without falling off the table.

 

 

 

kite investigation

today we did an activity where we had to do an investigation on kites. this is what I found out:

in case your head turned into a pumpkin and you didn’t hear / see anything until the videos finished each kite has one right angle. one right angel is 90°. each kite is congruent ( the same ) and there are four kites. the way to find out the right angle is to arrange the kites into a ninja star shape. then if the points add up to 360° then they all have right angels.

simple machines workshops

SESSION 1

 

 

In the past few weeks we’ve been working on simple machines. First we worked on Lego chain reactions. Lochy P and I were making the board bouncer. Here is a picture of the board bouncer.

The board bouncer uses an axel with a board on it. When a domino falls on the axel, the axel will wobble causing the board to bounce down.

Lochy P and I found it hard to get the axel to wobble because the dominos were too small to fall on axel.

SESSION 2

 

 

This session we worked with knex. We were given an instruction booklet from the teacher and we had to choose a model to make out of the knex. Lochy P and I chose the steamboat because none of the other groups chose steamboat and we wanted an original. Here is what we made.

 

 

 

 

I enjoyed making the steamboat because it was a lot like Lego. Did I mention I like Lego? If not then I like Lego. Knex are pretty much the best material that we can use in design because the pieces can be used in lots of different places and they are unique.

 

 

 

 

SESSION 3

 

 

 

Today we worked on pulleys. I think that pulleys were the hardest simple machine workshop because we couldn’t get the pulleys to work.  Lochy P and I found it hard to make the pulleys because the string was hard to control, when we moved the basket the string would fall into the side of the reel and get stuck, so the pulley couldn’t move. The purpose of the lesson was to get a pulley to lift a yoghurt container filled with marbles. Here is a picture of a pulley that we made.

Here’s what happened:

#1.The teacher told us what to do.

#2.Lochy P and I got paired up.

#3. We made the first pulley. It was easy because we only had to use one cotton reel and it was very simple.

#4.We made the second pulley. It was a bit harder because the string was going everywhere.

#5.We half made the third pulley but then the bell went for lunch. Plus the string was moving everywhere.

 

robots questions

q1: WHAT IS A ROBOT?

A robot is a being that is controlled by a program and a programmer. Robots can do tasks such as cleaning up nuclear waste. Robots can be used for entertainment such as dancing. They can be controlled by remote controls.

q2: WHAT IS NEEDED TO MAKE A ROBOT WORK?

It depends… Some robots need different materials to work. For example if you were making a spider robot you would need 8 legs 1 torso and 1 head, but to make Iron Man you would need 2 legs 2 arms 1 torso and 1 head. They all need a power source and a program, meaning they need a human to program them.

q3: WHAT IS A PROGRAM?

A program is a series of instructions like fd 10 would be forward 10 steps and rt 90 would be right turn 90°.  Some people study at university to learn how to write programs.  Programs have a special language to work, not always like English.

q4: WHY DO YOU THINK PEOPLE INVENTED ROBOTS?

I think people invented robots because people were too lazy to do things for themselves. Robots can also save money and time. Robots also do things that are too dangerous for people.
