This half term, we have been working scientifically using roads and a scientist called John McAdam, who invented tarmac, as our focus.
The children have enjoyed all our investigations and have learnt lots of working scientifically skills too.
First of all, we carried out a comparative test to see how a car travelled along different surfaces around school.
Then, using four different materials, each one was tested to see which made the best road surface. Water was added to see which of the materials had the best drainage.
Finally, we recreated the layers that made up McAdam’s road.
