One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This activity offers a simple way to investigate phototropism: the response of seedlings to different wavelengths of light. This technique will help students investigate this tropic response, using...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this activity, students investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator, giving opportunities to look at auxiliary bud development, root...

One of a series from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This practical introduces a simple method to grow radishes, for investigations into the effect of a range of factors on plant growth, including levels of pollutants,...

Investigating serious crimes such as murder, rape and terrorism requires forensic science experts. These people work alongside the police to find the evidence that will bring the culprit to court.

In this Catalyst article, Tony Hargreaves looks at criminal poisoning and shows how forensic science is used to...

A Catalyst article about road traffic accidents (RTAs). After the accident police and other investigators try to establish what went wrong. This may be with a view to prosecuting a motorist, or simply in an effort to improve road safety. An understanding of the physics of motion plays a large part in such...

This resource contains an activity in which children test the permeability of various rocks. It contains a brief summary of the background knowledge and a sheet in which observations may be recorded and conclusions drawn from the test.

This resource has been provided by Sigma Science.

These materials, from the Earth Science Teachers' Association, contain hands-on activities that will help students to understand processes such as the water cycle and phenomena like climate change and plate tectonics.

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology.

This activity allows students to investigate many factors that influence seed germination, including temperature, light, nutrient levels, pollutant effects, tropisms and so on.

It...

Produced by Teachers TV, this video illustrates how enthusiastic science co-ordinator Katrine Shears gives hints and tips about successful investigations using her experiments on sound as an example. Year Six children at Bobbing Village Primary School are conducting their own investigations to find the most...

The mathematical solution initially explains how to use calculus to find the stationary points of the curve y = x/(16+x²) by rewriting the equation as a product using index form and using the product rule to find the differential. The stationary points are found by equating the differential to zero and...

This activity will allow students a practical opportunity to apply the formula of speed to establish and consider why streamlined shapes are advantageous.

The activity gives students the opportunity to explain what...

In this activity, from the LSIS, students discover for themselves the importance of the perpendicular distance in moments. It is presented as a whole class discussion but can easily be adapted for small group work.

The activity uses a magnetic disc that takes about 15 minutes to construct. The activity will...

Vernalisation offers an interesting example of the way that plants have evolved to exploit the predictability of seasonal change and, in this case, to ensure that flowering occurs at an appropriate time. It also gives an example of how environmental factors control and...

Windmills and wind turbines are based upon the principle of trying to create a shape where air flow causes the maximum possible change in kinetic energy. Wind turbines are designed to convert the kinetic energy in wind into electrical energy to power millions of homes...
