I found our inclined plane activity an in between because it wasn’t satisfying. I learnt that a vehicle went down a ramp faster than when the ramp was more flat.
|
I give the lever activity, an in between because it took me quite a while to understand properly how a catapult works . I learn’t that the further down I pushed the spoon the greater force I used and the distance the load travelled. Also the load is what you want to move or lift,the force is how much energy I used to lift the load up.The fulcrum was the part that held the spoon to the popsicle stick.
|
I give the pulley a 10 out of 10 because I had lots of fun making a flag pole for the pulley activity. I learn’t that you use a pulley to lift up a load.
