HIV Life Cycle

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.

HIV replicates inside white blood cells called CD4+ T cells. Here, viral DNA integrates with...

Lymphatic Filariasis

Produced by the Wellcome Trust, this animation shows the complete life cycle of tiny parasitic worms as they move between human and mosquito hosts.

Lymphatic filariasis is a disabling disease found in low-income areas of many tropical and subtropical countries. Parasitic worms multiply in the lymphatic...

Malaria Life Cycle

From the Wellcome Trust, these animations show the life cycle of the malaria parasite. They illustrate how the parasite develops in the mosquito before being transmitted to a human host following a blood meal.

The protozoan then develops inside the host's liver and red blood cells, causing the symptoms of...

Schistosomiasis Life Cycle

This animation, from the Wellcome Trust, illustrates how several species of the Schistosoma parasitic worms exploit humans and fresh water snails. The parasites use rivers and streams to transfer between the two animals, using each for a specific phase of its life cycle.

The parasitic worms are able to...

Trypanosomiasis Life Cycle

Two animations, from the Wellcome Trust, illustrate the life cycle of the trypanosomiasis protozoan parasite. They illustrate the journey of these single celled parasites, which cause human African trypanosomiasis or sleeping sickness, from the gut of the tsetse fly into the human bloodstream. If left untreated,...

Tuberculosis - Infection and Transmission

From the Wellcome Trust, this animation shows how the human immune system attempts to contain a tuberculosis infection and how the bacteria are transmitted to new people.

Tuberculosis usually affects the respiratory system but it can develop in any part of the body. The human immune system commonly contains...

Zoom in on Your Genome

Produced by the Wellcome Trust, this animation helps to illustrate where and how the human genome is stored within our cells and bodies. It takes a journey which starts with the whole human body before looking into a liver cell and then the cell's nucleus. The animation shows the arrangements of chromosomes within...

Climate Change Activities

This interactive animation from BP Educational Service looks at the impact of global warming.
By moving the slider on the thermometer to increase the global mean temperature, students can see a different set of hot spots appear on the interactive map. Clicking on each hot spot reveals the possible impact of...

Interpreting Distance-Time Graphs with a Computer A5

In this DfE Standards Unit resource, students interpret linear and non-linear distance-time graphs using the computer programme Traffic. This program provides a simple yet powerful way of helping learners to visualise distance–time graphs from first principles. The program generates situations involving...

Performing Number Magic A9

In this resource from the DfE Standards Unit, students analyse simple number 'tricks', and explain how they work, using algebra. They then try to create their own variants of the trick, making it more impressive. Students will: develop an understanding of linear expressions and equations; make simple conjectures...
