Four children make statements about their relative ages but one child is lying. The challenge is to order the children from the youngest to the oldest.

A diagram is shown with horses arranged in fields around a rectangle. There are four challenges to move the horses to fulfill given criteria. A worksheet is also included for students to record their answers.

If a large force is needed, a simple machine can be used to convert a small force into a large force but requires that the small force move a larger distance and the large force a correspondingly smaller distance. The amount by which the small force is multiplied is known as the mechanical advantage. This principle...

A floor plan is shown from a museum. The challenge is to place two security guards so that they will be able to keep watch on the whole museum

This puzzle provides an introduction to simultaneous equations in three variables. Three combinations of coins are shown, together with the total value for each pair. The challenge is to calculate the value of each coin.

With just one fold of a square piece of paper, is it possible to make a triangle and a quadrilateral? Two quadrilaterals? A triangle and a pentagon? A further challenge asks students to explore the combination of shapes that can be made by using two folds of a square.

This puzzle provides a gentle introduction to simultaneous equations. Three pictures are given that show different combinations of three items from a menu, together with the total price for each meal. The challenge is to work out the cost of each item.

This problem looks at fencing chickens using pens. The challenge is to work out how many lengths are needed to create six separate pens for the roosters.

This combination problem builds up from combinations of three socks to six socks. Can students find a pattern and use it to work out how many socks would be needed to ensure a different pair was available each day for a month?

A sheet is shown containing six calculations that have been partially obscured by juice spilled on the sheet. The challenge is to work out what the calculations were, and their solutions.

This problem provides a gentle introduction to simultaneous equations. Three bags of shopping are shown: two have prices and one does not. The challenge is to find out the price of the final bag of shopping.

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the speed at which the temperature increases along a thermal conductor compared to a thermal insulator

• Identify materials that are good thermal conductors or...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify which of two objects or substances has the most energy in its thermal store when the only difference between them is temperature

• Identify which of two objects...

RAL Space is the UK’s national space laboratory where our thermal engineers and technicians help design and build spacecraft. They make sure that the components will work correctly and are protected in the extreme temperatures of space by using a special type of insulation. In this activity and presentation, pupils...

This resource supports students to understand the key properties of thermosetting and thermoforming polymers and provides examples of uses for these polymers. The resource contains a classroom presentation and student worksheet.
