In this investigation, students extract iron from a breakfast cereal and consider how our bodies are able to digest iron by looking at its reactions with hydrochloric acid.

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...

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. 

Students compare the water quality at different points in a stream or river using the standard procedure for finding the Trent Biotic Index score for samples of freshwater invertebrates.  The test was developed by the Trent River authority to detect water pollution. It allows comparisons of water quality to be made...

Students observe what happens to blood added to salt solutions of different concentrations. This is done in test tubes, although it may also be possible to observe what happens under a microscope. The students record their observations and attempt to explain what has happened to the red blood cells. They then...

Explore, Engage, Extend includes twenty sets of highly engaging practical activities to support teachers with assessment for learning in science. The activities generate rich assessment data, enabling the teacher to plan the topic in response to the children's specific needs.

This worksheet looks at electrolysis, its use in the extraction of sodium and aluminum and in the purification of copper. Having completed it, students are then asked to set up a simple electrolytic cell to obtain pure copper and calculate and measure the amount of product deposited at an electrode during...

Practising teacher and mindset expert Katherine Muncaster has combined with best-...

One of the major challenges in protecting the health of people in a city is to be able to provide water that is fit to drink. With an increasing populations we are faced with difficult questions:

Would people be happy to drink water that has been recovered from sewage directly?

Do we know or care what...
