Rapid V/I Curves

 Using @pascoscientific voltage-current sensor with the wireless airlink to create a very fast V/I straightline for a resistor and a not so straight line for a bulb.

Goldleaf Electroscope

 I really hadn't appreciated how hard it would be to get a gold-leaf electroscope working. The first model I had used dutch metal and I couldn't get it to work, but this model with real gold leaf did work eventually with me leaning how to attached the gold leaf properly. Putting the gold-leaf on is really quite difficult until you know how.

Woolly Human Gut

A few years ago my wife knitted the entire human gut. It is popular with the students as it is fun to hold and it is life-size so they a sense of the scales and proportion of the gut. It also fits in an abdomen sized clear bag which shows more what if looks like in the body.

Specific Heat Capacity

 Managed 4 specific Heat capacity experiments, Copper, Brass, Aluminium and Iron in 1 hour using @pascoscientific wireless thermometer and Joulemeter from @SciChemEdu  #iteachphysics

Looking at Hydrides

Using @Snatoms to look at the hydrides comparing their properties and looking at hydrogen bonding.

Investigating Heating and cooling

Investigating Heating and cooling using a couple of @pascoscientific wireless thermometers and Capstone. The difference was very dramatic and was much better than using a Leslie cube and different coloured cans. #iteachphysics
