This week, we have been learning about forces. Having explored Egypt on Google Maps, we wondered how the Ancient Egyptians were able to drag huge stone blocks across the desert to build the pyramids.
We learnt that there would be lots of friction between the rocks and the ground when they were being dragged so we investigated which material would have made dragging these rocks easier. We used Newton Meters to measure the amount of force it takes to move big rocks across a range of different materials. We found out that smooth plastic caused the least resistance.
