Flying Cake tins
A demonstration of Electrostatic charges repelling like charges caused by a Van de Graaff Generator. This causes the aluminium cake tins to fly away from each other and from the van de Graaff generator.
Ionic Bonds
Ionic bonds with dot and cross diagrams are hard to visualise. Using these card models made with a Scan n cut machine, the students seem to grasp the idea better. The real problem is to sort out a better Sulfate and Nitrate groups.

Lego EV3 to determine acceleration due to gravity
We have been using this Lego technics setup to determine the acceleration due to gravity and getting 9.8 m/s/s consistently. The students had to do the programming themselves from the formula which made it a bit harder.
Gas Stoves leak Methane when not in use
It’s
widely known that when methane is transported in pipes and it leaks the new
study has found that cookers leak methane even when they’re not being used. But
it is a worry because methane is 86 times more potent than carbon dioxide.
Methane makes up about 90% of natural gas which is used in our homes for
heating and cooking purposes. This recent study shows that even when heaters
and cookers are turned off methane leaks. Considering the amount of time a
cooker is used we can see that more than 75% of this leakage occurs when the
cooker is turned off. Ventilation can help the kitchen but it doesn’t help the
climate impacts of this Greenhouse gas and the results of burning methane. The only
way to do this is to cook on electric from a renewable source.
