This resource provides a set of videos of a practical investigation aimed at supporting working scientifically in the classroom and relating science to real world experiences. In the first video, Professor Brian Cox joins a teacher to find out how some...

This collection contains a range of resources produced by organisations such as the Royal Academy of Engineering and with the support of industrial partners including npower, Thales and Laing O'Rourke. Each of the resources helps to look at aspects of engineering in real-life contexts. Materials will be useful for...

National Moon day commemorates the day in 1969 when the astronaut Neil Armstrong was the first person to step on the Moon. This was a ground breaking moment for human-kind.

The resources in this list use the Moon to teach about various topics including:

• the phases of the Moon

The Science Museum in South Kensington welcomes over 2.8 million visitors each year and cares for our national collections in science, technology, industry and medicine – over 300,000 objects, some of which date back to prehistoric times, and including more world ‘firsts’ than any other single institution. Through...

In this Teachers TV programme, mathematics consultant Val Worcester joins Melanie Grant and Vanessa Clarke from Aston Tower, Birmingham as they reflect on the assessment activities used in their Key Stage One classes. The challenge for teachers in Key Stage One assessment is to design activities that will yield...

The initial activity in this resource asks students to start with x = 6 and write further equations where x = 6 is the solution. For example, subtracting two from both sides of the equation gives

x ­- 2 = 4

The next step is to use the equation given to build a more complicated one. An example is

A case study from the Engineering and Physical Sciences Research Council (EPSRC) which looks at the forensic evidence and intelligence that are left at crime scenes by footwear, gloves, tyres and fingers. New Latent Image Markup and Analysis (LIMA) software provides a fast, accurate way of transmitting and...

The materials in this resource are from the Secondary National Strategy ‘Progressing to Level 6 and beyond in science’ project. They were intended for science teachers who are focusing on developing writing in science – specifically explanations, arguments and descriptions.

These materials consist of general...

The first interactive sheet shows fractions where the numerator is 1. The fraction is converted into a decimal by long division and illustrated as the fraction of a circle. The denominator can be altered to be between 1 and 9. The next two sheets also show long division...

This article looks at epigenetics in plants.

Rooted to the spot, plants cannot run away from problems.  Instead,...

This lesson develops the concept of area of a circle. In particular students will:

• Sketch and construct loci involving arcs of circles
• Calculate the area of a circle, given its radius
• Calculate the radius of a circle, given its area

The opening question is about a goat...
