Exothermic Reaction

Adding Magnesium turnings to copper sulfate gave a nice temperature rise recorded on @pascoscientific Capstone. Different groups doing different experiments meant that we could easily share the data.

 

Magnetic field

 Measuring the changes in magnetic field with distance, using @pascoscientific magnetic field sensor and the smartcard to provide the position information.

Lightbox and Graphs

 Comparing two graphs can be difficult. If they are on a computer, then it's simple, but paper graphs need a lightbox so that one can be seen through the other.

Particle accelerator

 Building a PingPong ball accelerator with the students from some sticky copper strips and a mixing bowl powered by a Van de Graaf generator. It's not exactly fast, but it does move.

Eye Lens

Modelling the eye lens from @Pascoscientific. Looking at ordinary lenses just does not give an idea of how the eye works, but this lens changes as water is added and removed much in the same way as the eye lens works.

 

Online teaching

 Online teaching. Using multiple screens, cameras, visualisers controlled by an atem and stream deck to make on line teaching a breeze.

Hard Disk

Exploring how a hard disk works. Looking into the formatting and why a disk loses so much space on formatting and how this is used to access all the data.
