 Trying to find a good aquatic plant for photosynthesis experiments in the laboratory. Hornwort (Ceratophyllum dermersum) does about the best. Being a native species, it grows well in my pond all year round, so it also has good availability.

Evidence for brain damage

​Should schoolchildren head the ball? In our ​ A Level Psychology class we dug into whether lighter balls are truly safer and if heading could lead to brain damage. Research reveals some surprising insights!

Benzene

 Looking at a structural model of the benzene bonds to see if we can understand why it reacts the way it does and how we arrived through history to this model.

Momentum

 Investigating Momentum with elastic and inelastic collisions using the @pascoscientific smartcarts. Using either the velcro or the magnets, simple collisions can be measured, and using multiple stacked carts, we can simulate changing the mass visually.

Two Protractors

 Two protractors, the one on the left makes it easy for the students to do bearings, and the one on the right is the one that students have in their pencil case, which makes doing bearings much more difficult.

Total Internal reflection

 Seeing what we can do with total internal reflection - communicating down fibres, lighting Christmas trees and using endoscopes.
