From Science & Plants for Schools (SAPS), these materials encourage students to use disc diffusion tests to investigate antibacterial or anti-yeast properties. A wide range of products, both synthetic and natural, claim to have microbicidal properties. Students can...

This activity, from the Institution of Engineering and Technology (IET), focuses on understanding that changing the composition of a material will affect its properties and characteristics.

It is intended that...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and reliable practical activity allowing students to compare factors affecting photosynthesis. Possible investigations could include the rate of photosynthesis in sun and shade plants,...

In this practical, students investigate the effects of different levels of minerals (nitrates, phosphates and potassium) on the growth of radishes. Students sow radish seed in ‘soil’ containing different levels of 3 minerals - nitrates, phosphates and potassium. These minerals are present inside N:P:K fertiliser...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An intriguing way to demonstrate gravitropism in action over the course of a lesson. Using black film canisters, a freshly cut seedling stalk (hypocotyl...

This activity helps children to understand the components of computer systems, with a focus on input devices. It links this to their everyday experience, by comparing games controllers, keyboards, microphones and other everyday peripheral devices. The practical part of the activity involves creating programs in...

This activity helps children learn about computer systems and output devices. It relates these systems to those they encounter everyday, from headphones to printers and washing machine motors. They understand that programs make these devices function, and attempt a programming activity using Scratch and Lego WeDo....

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical activity, students to investigate the role of light in starch production in leaves during the process of photosynthesis. By using leaf discs rather than whole leaves, a number of...

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,...

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...

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...
