This report of the Central Advisory Council for Education (England) resulted from research into the state of secondary education, focusing on students aged 13 to 16 who were of average or below-average ability. The report was known as the Newsom Report, named after Mr J H Newsom, chairman of the advisory council....

In this STEM activity through practical activity pupils will develop their understanding of capacity, volume and fractions such as halves and quarters, as parts of a whole object. Pupils will have the opportunity to see fractions at work as they fill two half sized glasses to the top before pouring them into...

This is the classic investigation which demonstrates the idea of radioactive decay and half-life. There are lots of variations of this, but this one looks at using dice and removing those with a number 6. You then plot the graph to work out the ‘half-life’ of the blocks. This is a good investigation to make ...

In this video clip radioactive decay is modelled using the rolling of dice. The data are plotted on a graph and the half-life is determined.
