Rube Goldberg Machine

LI: to make a working Rube Goldberg machine by using the 6 simple machines.
Over the past weeks, in groups LS1 had to make a Rube Goldberg machine, We used the 6 simple machines. Wheel and axle, Lever, Incline plane, Pulley, Screw & Wedge had to be included. The challenges were turning a Chromebook on, helping Mr Wong roll dice and hitting a putter. Our scenario was turning on the Chromebook.

On the last week our group had managed to get the machine finish. We used four different types of simple machines a wheel and axle, pulley, incline plane and a lever. For the wheel and axle we used a car. For the Pulley we used a string from a yo-yo and latches from the window. For the incline plane we used a marble roll down a ramp. And used the dominoes as the lever. 

The most challenging task was creating the machines and trying to apply the 6 simple machines and communicating with our group to know what is going on and how we could help. I'd change another way of putting dominoes up without it falling because we always had to keep putting it up and the amount of sellotape we used.   

Screw

 

LI: to learn about Incline Planes
A screw is devide made of a tube bent spirally around a cylinder and use to raise water. So its used to pick up from a low point to high point. We had to fill in a poster, write down the definition, some answers to a test we were doing, and examples of inclines planes in everyday life. We made our own screw to use our of a tube, a stick, and tape. We had to try to see if it worked if it didn't we had to see what was wrong.

Pulley

LI: to learn about pulley.
A rope that is around a wheel to pull up a heavy load, which is like a incline plane but pulls straight up. We had a little play with ropes and a stick to see how pulleys work. We first started with one person pulling the sticks in with people holding on. We then used a rope and put a loop on the sticks and pulled with the rope. We then progressively added loops on the stick. We then had a poster with a bunch of questions on and we had to answer questions.

Incline Plane

LI: to learn about Incline Planes
A plane is a surface, and incline is like a slope. So incline plane would be a surface that has one side higher then the other. We had to ill in a poster Write down the definition, some answers to a test we were doing, and examples of inclines planes in everyday life. We had toy cars we had to test them using different incline planes. We had two test to do. The first was to push the car on incline planes that were on different angles, and the second one was to try to make the car keep going when it goes on the ground. We did the second one because when it went down there was a big gap so the car would go out of control.

Wheel & Axle | Lever

LI: to learn about wheel and axles and lever
A wheel is a circle that rolls along the ground. A axle is a stick or rod that goes through the centre of the wheel. A lever is a bar that rests on a fulcrum to lift up a heavy load by applying pressure on one side. We had a poster for both simple machines and we had to answer the questions on the poster. We then had to make a wheel and axle. We then later in the week tried to use the lever to pick something up.

Rube Goldberg

                     

LI: to learn about STEAM

For the rest of the term we are doing STEAM for inquiry. Science, Technology, Engineering, Arts, and Mathematics. We first looked at who Rube Goldberg was, we had to find out the 5 W's and H about him. Rube Goldberg invented the Rube Goldberg machine, which does simple task in a over-complicated manner. 

We then made a Rube Goldberg machine using body's. We had to try to brainstorm on how we could do it. We had to try to include a lot of things. Like rolls, turns, and more. We had to try to do the human Rube Goldberg machine being blindfolded as well.

MOTAT (Museum of transport and technology)

LI: to learn about STEAM
We went to MOTAT which was a really big museum with interesting and amazing stuff. We first went looking around MOTAT viewing artefacts, and saw a bunch of cool things. We saw a firestation with a firetruck used back in the days. We even saw a telecommunication exhibit with dial phones, and stuff like Morse codes. We then saw a car exhibit and saw a supercar, a car that Queen Elizabeth 2nd used, and saw car engines. Next we saw a old village with a classroom, church, workshop.

When we finished looking around we firstly made an electric car! We first had to make the body of the car using cardboard. The he engine was a motor and a fan. The wheels were small wheels, and a skewer. We then had to connect the parts in some way.

Lastly we made a flashlight using some connecting blocks. We first had to use the motor again, and connect a LED light to the motor and span a cog to make the light flicker. We then had to use the connecting blocks, cogs, and more to try to keep the LED Light on instead of it just flickering.
