Last week we debated whether the craze for fidget spinner toys was a good thing and whether it really helped people focus and concentrate at school or not. We found out about different opinions from the USA and UK, from teachers and parents, and decided there were alternatives which could do the job just as well or even better. We will be selling our alternatives at the School Fair.
We attempted to make our own homemade spinners with cardboard and coins, and lego. Some of them worked quite well. We designed some amazing fidget toys that combined lots of different sensory elements.
This week we used another craze - bottle flipping - to think about probability and chance, what makes a fair test and the variables you can adjust to try to make good comparisons. We predicted and hypothesised what we thought the outcomes would be and explained why we thought as we did. We will go on to work out the fraction of the attempts that were successful under each set of variables, and convert this to decimals and percentages.
