Chameleon bubbles

Chameleon bubbles are formed when a sodium alginate solution is dropped into a calcium chloride solution.  The bubbles are filled by an acid‐base indicator solution; so, adding the beads to acids or bases leads to colour changes inside the bubbles by diffusion and pH change. Students can learn about acids, bases,...

Data-logging with BBC micro:bits and MakeCode for modelling with Excel and GeoGebra.

Recent developments in MakeCode now make data-capture from micro:bits very simple via the USB cable.  The data can be graphed in real time in MakeCode and exproted as CSV files.  Using tools such as Excel and GeoGebra's Spreadsheet View, the data can be manipulated, analysed and modelled.  With a pair of...

Satellite Telemetry Interpretation

As part of the FUNcube STEM satellite outreach programme we have developer a student and teachers pack showing how to interpret rea data from graphs.

These can be found at: https://funcube.org.uk/education-outreach/

Hypatia Toolkit

The toolkit is a ready-to-use digital collection of modules aimed at
teenagers to be used by teachers, informal learning organisations,
researchers and industry.
The aim is to engage young people and especially girls in STEM
and in the discovery of the variety of STEM related careers in a

Lesson 5: Melting Glaciers and Their Impacts

The glacier experiment sequence from the previous two lessons is repeated here, accompanied by the glacier vulnerability score chart. Two sets of student assessment tasks are given for levels three to seven. One of these allows teachers to print and distribute the questions most suitable to their class or to...

Lesson 3: Research a Glacier

In this resource, students investigate how glaciers respond to climate change by building a model of a glacier and observing how fast it melts. The class can be split into groups, each researching a different glacier so that comparisons can be made. Information sheets are provided for seven glaciers. This resource...

Lesson 4: Glacier Research

In this resource, students investigate how glaciers respond to climate change by building a model of a glacier and observing how fast it melts. The data is analysed further using the Glacier vulnerability matrix which ranks the glaciers risk of melting due to its area, thickness, altitude and latitude. This...

Mystery of Gibraltar

Students learn about the solutions of a particular substance which...

Eating nails

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.

Gelli baff

Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...
