Boosting onto year 13

 Some down time in the holiday is an excellent time for getting ahead and with year 13 work and revising some of the old year 12 work keeping the hand in on the old C1 and C2 papers. 

Rates of Reaction

Studying rates of reaction is possibly one of the easiest and hardest things to study in chemistry. Looking at concentration, particle size and temperature and then at A level measuring the rate and determining what is going on.
 

Induction Apparatus

 

Trying out the Eisco Induction Apparatus to induce a current using a magnet or a coil within a coil or as a coil within a coil with an iron core to dramatically increase the effect

Investigating Friction

Trying out different frictional surfaces and different objects to see how different shapes and surfaces work. The students were surprised at the results which were not as obvious as they thought.

Carpet had a higher frictional co-efficient  than the glass-paper and in took quite of investigating to find out why.

 

Setting up a microscope

 Setting up and using a compound microscope. Although the students have used them many times, they forget how to focus away from the slide and struggle to set up the lighting properly 

Calculating the acceleration due to Gravity

 Calculating the acceleration due to Gravity online using the @Pascoscientific picket Fence and and the light gate in its stand. After 20 repeats we managed an average of 9.765, which I felt was quite good for doing this online - live in front of an audience telling me what to do.

Young-Laplace Law

Hookean showed a nice demo of differential pressure that I hadn't tried before. When I tried to reproduce it I got very different results in the experiment and had to look into the history books of what was going on
