This activity, created for use by teachers and/or Environment Agency STEM Ambassadors with the help of a teacher, provides the opportunity for pupils to learn about the water cycle. Pupils are introduced to the water cycle by asking them to...

In this set of activities, children will learn about the water cycle and, in particular, how water in the soil contributes to the cycle and responds to changes in it.

Activities are:

• learning about the story of a snowflake to illustrate the water cycle
• investigating evaporation and...

This video begins with the mnemonics Very furry lambs and Cute furry lambs.

Using a model of a railway carriage (its length, x and time taken to travel, t) the equation for velocity (v = ^x/_t) is derived.  Equating the length of the carriage to wavelength, λ and time to the period, T the...

This Catalyst article looks at X-ray free electron lasers that generate intense beams of X-rays and are used to reveal the structure of complex molecules.

Theory Into Practice, from the Nuffield Foundation, was published in the early 1970s when there were significant developments both in the style of science teaching in schools and in the arrangements for teaching education and professional development. The resource includes activities designed to help teachers to...

This activity introduces the idea that climate change is leading to a greater risk of flooding due to higher levels of rainfall in a short period of time. The main part of the activity is a design challenge for the pupils highlighting how...

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...

A pair of videos that studies the thermal insulation properties of bubble wrap. This first video allows students to see an experiment that investigates how increasing the number of layers of bubble wrap around a beaker affects the cooling of hot water. The second explains how to interpret the data, plot the graph...

This experiment allows you to investigate the boiling point of brine and the melting point of lead using a potentiometer arrangement. An alternative approach using digital voltmeters is also included at the bottom of the sheet.
