From the Wellcome Trust Sanger Institute, this resource contains an animation that takes a journey which zooms in from the surface of the body into a cell. It illustrates the relationship between the nucleus, chromosomes, genes and DNA.

Each stage is at higher magnification to show where the genome is found...

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...

This group of interactive excel worksheets look at the series of identities of the form

aSin(x) ± bCos(x) and aCos(x) ± bSin(x),

where a=RCos(α), b = RSin(α), R=√(a...

This simulation allows students to test the pH of substances like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. It can be used to visualise the relative number of hydroxide ions and hydronium ions in solution, switch between logarithmic and linear scales, and investigate whether...

With this simulation students can test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. They can also investigate how adding more of a liquid or diluting with water affects pH. Sample learning outcomes include:

• Determine if a solution is...
