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.

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

Cracking Hydrocarbons

In this classic experiment, from the Royal Society of Chemistry, students heat a large molecule with a catalyst and collect the gas produced. The gas produced is tested with bromine water for the presence of a double bond. The resource is set out as teachers' notes followed by the students' page which presents the...

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...

Electrical and Electronic Engineering

Produced for Future Morph, this resource includes a video in which a student talks about his course in electrical and electronic engineering. He describes how one project was to make and test a circuit that included a light-sensitive resistor. A second activity describes a class experiment...

Mystery of Gibraltar

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