The first interactive sheet shows a table of pairs of integers for students to reveal the factors and sets of multiples. The HCF and LCM can be revealed. New pairs of digits can be shown, either easy or more challenging. Each number is shown as the product of its prime...

This animation, from the Wellcome Trust, shows how the human immunodeficiency virus (HIV) infects white blood cells and uses its RNA to produce a strand of DNA which becomes integrated in the host cell's genome.

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 resource is based on the Inventive podcast. The podcast mixes engineering fact with fiction. Each podcast features an interview with an engineer. In this activity, manufacturing engineer Greg Bowie is the inspiration for Emma Newman to write 'Healing the Fractured'.

Short audio clips about the...

This activity challenges students to design, and agree on an optimal route for, a village bypass, subject to the Highways Agency constraints for road design. Students use the provided software or physical resources and measure lengths of lines and curves, fine tune cost-benefit trade-offs, interpret data, convert...

This is a series of interactive excel sheets that look at histograms.

The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a...

This animation shows how bacteria exchange genes on small pieces of DNA called plasmids through a process called horizontal gene transfer. 

Bacteria are able to exchange genes quickly within a population on small circles of DNA called plasmids. This animation shows how bacteria exchange plasmids through a...

This resource from the ABPI introduces students to the major endocrine glands, and hormone function in puberty, the menstrual cycle, pregnancy and growth. Specific examples include insulin, adrenaline, ADH, and plant hormones.

In this activity, students explore the miss-match between real and perceived risk by exploring the risks of dying unexpectedly from various causes. Starting from known fears and comparing them with real-life data, students can recognise that these fears are often unfounded. Students have the opportunity to learn...

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,...

Human Torch is a 'learning adventure', sponsored by the Health and Safety Executive and provided by the Association for Science Education (ASE).

The resource combines computer-based activities with video and experiments. Human Torch begins with a short dramatic video scene showing a victim who burned to...

This resource is based on the Inventive podcast. The podcast mixes engineering fact with fiction. Each podcast features an interview with an engineer. In this activity, electronics design engineer Shrouk El-Attar is the inspiration for Tania Hershman to write 'Human Being as Circuit board, Human Being as Dictionary...

This program begins with graphs of the hyperbola in the form x²/a^...

This resource is based around the chemical composition of the human body and the origin of elements in the universe. Students can input a mass in the spreadsheet to see what proportion of their mass is from elements created in the Big Bang, in stars and in supernovae. Graphs are also shown for the relative...

In this activity students are asked to construct a simple mathematical model to help decide whether or not the umpire has made the correct decision. Students are required to revisit and test assumptions made in their initial model, make estimates of likely uncertainty and apply their model to similar situations....
