Complex Numbers: 10 Questions

MEI provides this interactive resource for complex numbers.

Random questions are generated for calculations using complex numbers and correct answers are provided where necessary. Students aim to answer ten questions correctly in a row.

It is a useful resource which enables students to reinforce their...


From the ABPI this interactive resource provides students with information on the cause, symptoms and treatment of diabetes. The resource is offered at two levels, for students aged 14-16 and an advanced version for post-16 students.

The Argand Diagram

This MEI interactive resource for complex numbers demonstrates the Argand diagram.

This flash file can be used to plot a point in the complex plane. In this plane on the horizontal axis are the real numbers and on the vertical axis are the imaginary numbers. The point can be picked up and moved into all four...

Chagas' Disease Life Cycle

From the Wellcome Trust, these animations illustrate the life cycle of the protozoan parasite that causes Chagas' Disease.

The parasites use a blood-sucking insect called a triatomine as an incubator and vector. The protozoan parasite mautures and reproduces in the insect before being deposited on humans in...

Dengue Virus Replication and Transmission

Produced by the Wellcome Trust, these animations take a detailed look at the molecular mechanisms that allow the dengue virus to subvert the cells of its mammalian host, allowing it to replicate and spread. Dengue is an example of an RNA virus.

Being bitten by a mosquito carrying the dengue virus can lead to...

DNA to Protein - Transcription and Translation

This animation, from the Wellcome Trust, illustrates how the DNA code is used to build protein molecules inside our cells.

It shows how, during the process of transcription, polymerase unzips the DNA and uses it as a template to produce a strand of messenger RNA (mRNA) . The animation then goes on to show...

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...
