This video models the distance between the Earth and moon using a basketball and tennis ball. It shows that often diagrams we use are not to scale and so can be misleading.

This video discusses how data is coded and stored. It takes a look at the genetic code in humans and shows how it could be stored as 1.5Gb of data.

This lesson, linked to the Intergovernmental Panel on Climate Change (IPCC) report, aims to answer the question 'How often will a heatwave hit the UK?'

Students examine datasets to explore the frequency with which hot events occur and are required to interpret and draw box and whisker plots. Students are...

This video shows people’s misconceptions regarding the age of the Earth. It shows how imagining the difference between a million and billion is very difficult for people to do.

The video uses an arm span to model the age of the Earth and shows how recent in the Earth’s history the evolution of more complex...

This video shows how electromagnetism can be explained using either models of magnetism or of electric fields, induced by length contraction caused by special relativity. Length contraction (Lorentz contraction) occurs to anything that is moving – relative to something moving...

From the Wellcome Trust Sanger Institute, this resource introduces the Human Genome Project (HGP).

A short animation gives:

* an introduction to DNA and genomes;

* an overview of which countries were involved in the international Human Genome Project;

* a description of the processes,...

The animal kingdom contains an abundance of exquisite natural patterns from the stripes of an angelfish to the spots of a leopard. But how do these arise during early development? This Catalyst article looks at Turing mechanisms as a way of explaining how patterns develop as an animal grows.

In 1952, Alan...

Produced by the Industrial Trust, Business & Education South Yorkshire and JIVE (Joint Interventions), this leaflet identifies hints and tips to help organisers of visits to industry. Often organisations that are prepared to offer industrial visits to their sites are unaware of the action they can take to make...

This research was Published in 2014 and presented at the ESERO 2013 Conference.

The purpose of any teacher continuing professional development (CPD) is to ensure a positive change in pupils’ outcomes, yet the evaluative evidence to support this relationship is often weak or missing. Using the CPD programme...

This video explains that to compute the prime factors in a 2048 number would take a classical computer years, yet the ability of a quantum computer to use superposition, which reduces the number of steps to complete a computation, makes it possible in minutes.

The explanation

The...

Teaching Enquiry with Mysteries Incorporated (TEMI) intends to prepare students for enquiry-based learning by introducing them to challenging and fascinating phenomena. TEMI resources make use of unknown and uncommon observations as mysteries for students to solve.  This resource looks at what makes a good mystery...

A Catalyst article about the Hubble telescope exploring a barred spiral galaxy, known as NGC1672 in the astronomers’ New General Catalogue. The image was made by the Hubble Space Telescope (HST), and was released in April 2007. NGC 1672 is situated 60 million light years away, in the constellation of Dorado. The...

Produced by the Royal Observatory Greenwich, this collection introduces Hubble’s law and the expansion of the Universe. Included is an online video that discusses how big the Universe is. Material is differentiated for key stage four and key stage five students. The key stage five content links the recessional...
