In Science this week, Oaks planned and carried out an investigation to measure how restricted or blocked arteries affected blood flow.

We used 4 cups, each with a different sized hole to represent the size of a blood vessel. We measured how long it would take 100ml of liquid to empty in each cup. We recorded out work in small groups and did it 3 times with each cup so we could work out the average.

At the end of the session, we compared our results with our predictions and discussed what this showed us and proved.

The children had a great time working in small groups and work tremendously hard to involve everyone at each stage of the experiment.
