4th class conducted an experiment on the effects of different heights and materials on the speed of toy cars. We watched a range of videos as a stimulus and get us thinking on different heights.

We then wanted to see if this was actually true. We wrote up our opinions as a class on what we thought would be the outcome. We used a variety of materials including toy cars (different types-large and small), ramps, school books and a metre stick.

At the end of the lesson we came to the conclusion in our results that the higher the ramp the further the car would go on the ramp and onto a flat surface. We had a wide range of lengths which we could calculate with our metre stick.

Secondly we then tested the effects of different surfaces on the car. We used carpet, sandpaper and felt like materials. We as a class felt the texture of the materials first and then decided our opinions on which surface would be the best one.
