ASK THE CHILDREN WHAT THEY FOUND OUT!

We spent a lesson creating simple series circuits.
Wires. bulbs and batteries.
Some children went on to add a switch into their circuit.
We spent a lesson talking about the risks of smoking and ordering them in severity.
We designed and carried out our own heart rate experiment.
We took our heart rate:
During a rest period (Lying down)
Once after two different quick moving activities.
After the mile a day.
We then compared all of the rates and we were able to say when our heart rate would be at the highest and why.
We made our own working circulatory system!
During the first half term's science lesson Maple class are looking at the circulatory system. During one of the lessons we made our own 'Blood'. Each ingredient represented a different component of blood.
