In this resource the head of a circular snowman rolls around its circular body to make one trip back to where it started. The ratio of the diameters of the circles is given. The challenge is to find how many times the head will revolve throughout the journey, and find a general rule.

The resource contains a...

This Science upd8 resource revolves around the concepts of evidence and validity. A chocolate manufacturer claims its new, high cocoa bar is good for your heart.

But is it? This is the context for teaching students how to evaluate evidence and the 'how science works' concept of validity. The activity is...

Students first evaluate existing alarm systems and learn about a burglar’s attitude towards them using a video featuring reformed criminals. They are then briefed to create a working door access and alarm system using a BBC micro:bit and selected input and output components such as LDRs, reed switches, buzzers and...

Reducing energy usage in the home saves money, increases energy security and reduces the need to burn unsustainable fossil fuels. The first step in doing this is monitoring how much energy is...

A section of a regular polygon is shown with diagonals drawn from a hidden vertex. The angle between two diagonals their corresponding sides are given. The challenge is to work out how many...

This extension activity, from the Institution of Engineering and Technology (IET), follows on from the How Much Waste?...

This activity, from the Institution of Engineering and Technology (IET), challenges students to calculate the dimensions of an underground tunnel system. Students are encouraged to move beyond an ‘out of sight, out of mind’ approach to sewage as they use and develop...

This activity focuses on the link between water usage at home and the number of people living in their household, as well as comparing the water usage within the UK to that of other countries.

Students estimate how...

This activity focuses on the link between the UK’s current water usage and the predicted increase expected in the future. Looking at a water board website, students think about how the website is set up and the formulae that are being used. They then work in groups to...

Using the presentation as stimulus material, this activity asks students to consider products in terms of their benefits to society and to justify their point of view. This activity allows students to explore social, ethical, economic and health issues relating to...
