Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

Ecology is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and experimental ideas...

These activities allow students to model how environmental scientists compare diversity in different ecosystems by using ordinary playing cards as ‘species’ to generate data to calculate Simpson’s Diversity Index. This can be completed in a single lesson. Some students find the concept of species diversity quite...

Electronics and A.C. is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education. Each title brought together the best of the teaching notes and experimental ideas from members of the association...

Energy and Chemistry is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and...

Produced by Science & Plants for Schools (SAPS), these materials give a range of suggested activities that investigate enzyme activity in ripening fruit. These include:
• the changes in enzyme activity during ripening and storage
• the activity of the same...

In this activity, students are asked to make a bioreactor containing an immobilised enzyme and use it to produce lactose reduced milk. They then assess the effect that temperature has on the enzyme driven reaction within the bioreactor. 

These activities, from the Institute of Physics, look at electrical circuits. They provide a review of previous knowledge and introduce the language needed to cope with the greater depth of learning at post-16 level. Activities include: • a discussion about electrical circuits to reinforce knowledge and highlight...

From the Institute of Physics, these activities present a range of examples involving different types of charge carrier and links the measured current to rates of flow of charge. The activities consist of a series of demonstrations which could be set up before the lesson. These include: • considering different...

From the Institute of Physics, this learning episode shows that charge carriers in good conductors usually move very slowly. It illustrates the derivation and use of the equation I = nAvq.

A range of activities include:
• viewing the movement of permanganate ions in an electric field
•...

From the Institute of Physics, this learning episode provides a quantitative definition for resistance (R = V / I) which reinforces the qualitative notion that more resistance means less current. It looks at Ohm’s law, describing that this is not the same thing as the definition of resistance.

Activities...

Produced by the Institute of Physics, in this practical investigation students measure the current and voltage characteristics for several components and identify ohmic and non-ohmic behaviour. Students determine the V-I characteristics for: • a carbon resistor • semiconductor diode • a filament lamp In addition,...
