Your task today is to make predictions
Your challenge is to make simple spinners using cardboard discs with a cocktail stick or pencil pushed through their centres. You will create 2 spinners, one with a blunt end, one with a pointed end. You will then explore different surfaces to improve the spinners rotations.
Once you've made your spinner, test it to see how well it will spin.
Are you happy with your design?
What surface do you think the spinner will spin best on?
I think that my spinner will spin the best on.............
Now we will try your spinner on different surfaces - predict if it will spin well or not, then time it to see how long it will spin for.
Which surface was the best for your spinner?
