This Catalyst article looks at how our knowledge of the human genome has increased greatly during the last 10 years, and genome sequencing techniques have become much faster. On 26th June 2000 it was announced that scientists had completed a first draft of the human genome, the DNA instructions for making a human...

The terminal velocities of cupcake cases are calculated in this video and a graph of mass versus terminal velocity is plotted to investigate the relationship. 

In this activity, students review their results from a previous investigation to form a hypothesis, consider the validity and size of the data set collected, and question if the data would be sufficient to confirm their claim.

A Catalyst article exploring the testing of new medicines to see if they are safe for people to take. The effects on cells of a potential new drug are investigated using tissue cultures of human or animal cells. Some tissue cultures use fresh tissue samples, but most come from well-established laboratory cell...

This resource provides an activity idea and a recording sheet for testing how sound travels away from a source. In the activity children learn to recognise that the sound heard from a source gets fainter as the distance from the source increases.

This resource has been provided by Sigma Science.

In this Triple Crossed activity, from the Centre for Science Education and supported by the Astra Zeneca Teaching Trust, students are provided with information about Charles Darwin and his work.

The Theory of Evolution by Natural Selection is discussed and students are asked to comment on the...

Several different treatments are used to autolyse yeast cells. The viability of the autolysed yeast is then tested by: plating out on agar; testing for dehydrogenase activity; microscopic examination with methylene blue.

In this...

An average of 39 million tonnes of untreated sewage overflows into the River Thames each year from London's Victorian sewerage system. This collection contains series of teaching and learning resources linking mathematics and science to the Thames Tideway Tunnel project, a major new sewer that will help protect the...

In this activity, students investigate the three main types of memory - sensory, short-term and long-term. An explanation is given for each one and linked to a memory experiment. Students are also given five memory tasks to complete which include looking at factors that affect peoples' memories and ways in which to...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the pupil in an eye as a hole that light can go through

• Explain how luminous objects can be seen when light from them enters the eye

• ...

This activity, from the Royal Observatory Greenwich, looks at Hubble’s law, whereby students use real data from the Sloan Digital Sky Survey to plot a graph from which they can obtain the Hubble constant. Students then look at the possible sources of error in their data and use this to calculate the uncertainty in...
