Wheels & Axels | Lever

 

LI: To build an understanding of what a wheel and axel is.

A wheel is a circular object that makes another object move and change direction. An axel is a mechanical object that holds the wheels in form. We made a slide presentation in pairs and my partner was Sulia. To do this we had to experience with a car which has both wheels and axels. We also had to push the car on its side for every surface. We had to push the car we had on different surfaces with the same amount of force to see the difference. Mr. Ogilvie had set up three ramps for us to try it with our car. The car went pretty fast on its wheels when we put it on the ramp and then when it came to the ground it went a long distance. When we put the car on its side the car did go fast when it was on the ramp but didn't go that far when it got to the ground. When we push the car on the floor the wheels reduce the friction there fore it goes smoothly, but when the car was on the ramp there was gravitational pull to the car so, it went fast.



LI: To build an understanding of what a lever is.

A lever is a long rigid body with falcrum along its length and it also rests on a pivot. We did an activity in our pairs from the wheel and axel but we also had to partner up with another pair. In our group there was: Fau, Charlize, Sulia & I. We first made a lever out of a long stick. Our objective was to make an object go up on the lever. We lifted a teddy bear with the stick. When we made the pushing point away from the teddy bear we had to use our full strength, but when we put the pushing point even we didn't have to put much force on the lever. After the first acivity we had to fill in the questions on a DLO. We also had to
