1. Climate Change (Scotland only)

This experiment raises awareness of the issues associated with climate change and has a particular focus on reducing carbon dioxide emissions through renewable energy sources and energy efficiency. Students begin by investigating different sources of energy and how energy use is measured. Students then focus on wind turbines and PV cells before being introduced to the energy debate. Finally, students investigate energy efficiency.

This experiment has been developed with funding from the Scottish Government.

2. Coming soon - Camera Optics (Scotland only)

This experiment gives students a general introduction to optics and the application of lenses. Students begin by exploring the most basic of all cameras - the pin hole camera – before making their own to take a photograph with. Students are then introduced to digital cameras and investigate concepts such as resolution, file sizes and pixels.            

This experiment has been developed with funding from the Rank Prize Funds.

3. Resonance

Students start this experiment by investigating what sound is with slinkies, wine glasses, tuning forks, their voices and a loudspeaker. Having measured the resonant frequency of a wine glass, students make a wine glass resonate using just electromechanical energy from a loudspeaker matched to the natural frequency of the glass. The highlight of the experiment is seeing the glass flexing whilst illuminated with a strobe light.

4. Hele Shaw cell  

This experiment investigates oil extraction by challenging students to get as much “oil” (glycerine) out of the cell as efficiently as possible. Prior to being set this challenge, students learn about how oil is formed and why it is important by introducing them to fossil, rock and oil samples. Students also explore surface tension, density and viscosity. Overall, this experiment is a means of understanding and simulating how oil is extracted using sea water, and why a large reservoir of oil remains in the ground.  

5. Scattering

During this experiment students investigate why sunsets appear red and why the sky is blue. Adding Dettol to a tube of water, illuminated by a light source from below, illustrates Rayleigh scattering which is the cause of the sunset and sky colours. As an additional part of the experiment students explore polarization before creating a fructose solution in the tube. By passing polarized light through the solution and viewing the tube with polarized filters, students observe a spiral rainbow – a result of the fructose molecules scattering the light and changing the plane of polarization of light as it comes up the tube.
