A level Math

 Students working out just what formulae are and are not in the exam sheet. Then, the panic can begin to memorise the formulae that are not given.

Fun with Electrostatics

 I'm having some fun with the students investigating Electrostatics. We are deflecting water, moving suspended rods, charging hair, fixing balloons to walls and ceilings, and fixing plastic and paper to windows with no glue, just some charge. Then, using amber to clean a PC fan of dust.

Elodea photosynthesis

 Finding out the best aquatic plant to demonstrate the effect of light intensity on the rate of photosynthesis using a few different plants. I have been getting the best results from Ceratophyllum demersum 

Online Maths Tuition

 Online Maths Tuition goes through some tricky bits that students find difficult - reading the question and asking themselves - what is this question about, and where do I start?

Vela

 Found my Vela when searching through the loft. 40 years ago, it was a great tool in the science lab, grabbing data from some experiments and squirting it into a BBC microcomputer. 

Orbitals

GCSE Chemistry: Trying to work out how those electrons are arranged in the orbitals and if any pattern can be seen. Working from a periodic table, it takes a while for a pattern to be seen, and the word spreads around.

online determination of acceleration due to gravity

 This is an online lesson that shows acceleration due to gravity using the @pascoscientific light gate and a picket fence. It works very accurately and is easy to demonstrate so that the students can see and understand what is happening.
