Science – Ramps – Autumn 2021
To investigate how well balls rolled on different surfaces, we first planned which variables we would keep the same and what we would change. We then made a ramp and rolled a ball on different surfaces, like the table top, grass, carpet and paving slabs. We measured how far the ball rolled and recorded it in a table. The next week, we used the iPads to enter the data on Purple Mash and created bar charts that show our results.
