Produced by Science & Plants for Schools (SAPS), this investigation looks at stomatal opening and closing in Commelina communis (Asiatic dayflower). This is achieved by varying the turgor of the guard cells by bathing lower epidermal peels in solutions of different osmotic strengths. Changes in guard cell...

Stop the spread is a new STEM challenge for students aged 7 to 16. Highlighting the global issue of infectious disease students design, build and test a model of a hand washing device and produce educational materials for children in Kenya to encourage hand washing. It is accredited for the British Science...

From Science & Plants for Schools (SAPS), these practical activities allow students to investigate how woody and herbaceous plants support their shoots, branches, flowers and fruits and shed them at the appropriate time.

A number of investigations are suggested that can be adapted for students over a...

From Science & Plants for Schools (SAPS), this practical activity was developed for Scottish Highers specifications, but the protocol can equally well be used for other specifications.

Students sterilise seeds of...

Aimed at Key Stage Two, this resource looks at variation in the size of body parts and how this may affect performance in sport. Providing curriculum links to PE and the topic animals including humans, it also aims to develop enquiry skills. Follow the character Fizzy as she sets the children a series of questions...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the taste of different fruits and vegetables. Domesticated fruits and vegetables have all been selectively bred so that they contain a particularly attractive taste for humans.

In this activity, aimed at primary level children learn about micro-organisms and hygiene by looking at swine flu and its symptoms. Using data on the number of cases of spine flu in the UK children discuss how viruses are spread, consider how they can be contained and learn how scientists use current data to revise...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This reliable and enjoyable practical gives students the opportunity to observe the different pigments involved in photosynthesis using thin layer chromatography (TLC). A low-cost method to get the...

These activities, produced by The Centre for Industry Education Collaboration (CIEC), help students understand about the formulation and design of coating used for tablets taken as medicines. Designed originally as a unit of GNVQ teaching, the materials contain a range...

This set of demonstrations into the effects of tropisms on seedlings is both simple and extendable. Seeds sown on damp cotton wool in Petri dishes are grown either flat, or stuck vertically to a wall, showing the different effects of gravitropism. After a week, students...

This activity considers the probability of events happening and involves calculating simple probabilities and expressing them in terms of fractions and words. Children consider the probability of real events. They then work out the chance of choosing a certain sweet...

In this SATIS Revisited resource the activities take students through a comparison of the risks associated with different activities using data at personal, community, national and global levels.

There are three activities in this unit, which have been written to be followed sequentially. Students work...
