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 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...

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...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical, student investigate how lead inhibits catechol oxidase, an enzyme which is easily extracted from a banana and which is responsible for turning fruit brown. Measuring the intensity...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A simple yet accurate protocol looking at the results of the enzyme catalase. Catalase is a widespread enzyme, protecting the cell from toxic effects of hydrogen peroxide by catalysing its...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A standard protocol which is used to extract phosphatase enzymes from plants, including a method to calculate the rate of reaction. Phosphatases are enzymes widespread in plants easily extracted from...

Understanding the osmotic potential of plant cells is a key part of understanding...

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 look at potato cyst nematodes, a serious pest of food crops. This is a good example of parasitism to study as...

This protocol allows students to investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator. The investigations give opportunities to look at auxiliary bud development, root development, and leaf abscission in Coleus. The method is suitable for independent investigations by...

All life forms on Earth are based on organic biochemistry. This activity requires students to analyse an unknown soil sample (just recovered from a space mission to another planet!) and look for signs of possible indicators for life. Curriculum areas covered: • Cell biology • Food tests, including starch, sugar,...

This protocol allows students to demonstrate and test Koch’s Postulates using apples infected with the fungus Penicillium expansum. The required experimental work extends over 3 to 4 weeks, but the essential steps can be demonstrated in a single practical session if students are provided with cultures and infected...

Could there be life on Mars? Perhaps so, although the high intensity of UV light means that it is unlikely to be found on the surface. The experiment demonstrates how bacteria grown on agar plates can be killed off by UV exposure. Curriculum areas covered: • Microbiology • Cell biology • Aseptic technique The video...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A reliable way to demonstrate photosynthesis in the classroom. When the pond-weed Cabomba is placed in a solution of sodium hydrogen carbonate in the presence of light of appropriate intensity, it...

The main aim of this resource is for students to understand the impacts of anthropogenic nitrogen pollution on heathland plant communities. The resource provides practical, scientific investigations without the need to organise a field trip.

The resource is divided into three separate activities:
*...
