Long Scale Galvanometer

 My long scale Galvanometer arrived, so now it is considerably easier to see evens rather than trying to observe a needle flickering. So now we should be able to do some more interesting experiments

Investigating ECG

Investigating the students ECG using the @Pascoscientific sensor and Capstone to gather and analyse the data. This gave a clear view of what was going on in the heart of healthy A level Biology students
 

Chromatic Bells

 Looking at Chromatic bells. Why is a scale a scale? How do the black notes work? What are the frequencies? Is the gap the same? Having some fun with music and physics.

Melting Gallium

The students complained about the Heat. I agreed and said it was hot enough outside to melt metal. No they said, but we took the Gallium outside and sure enough it turned to liquid.

Distillation

 Separating and collecting a liquid from two or more liquids. After the students had fermented some orange juice we collected some nice smelling alcohol which burnt really well. Surprised a few students that it did burn.

Damped Harmonic Motion

Using the @Pascoscientific smartcart and Capstone to record the damped harmonic motion as the cart moves up and down the track. Adding to the mass of the cart can achieve almost complete damping
 

Ready for Microbiology

Getting ready to do some microbiology experiments. Agar plates prepared and bacteria happily growing in the broth. Now to find ways to kill them with plants from the garden.
