I came across this Ted video on Squishy Circuits, presented by AnnMarie Thomas from the University of St Thomas and found it to be a suitable activity for kids. I shall attempt to make some when I am free with instructions from the following site:

As I was contemplating the potential of combining conductive and insulating dough to make fun toys with the help of electric motors and the learning that can come from it. Apart from the obvious learning related to electrical resistance and current, we can even learn about flotation and fluid dynamics by building floating boats of different hull shapes.

18 Must-Have Items for a Physics Teacher

Many a science teacher would have wanted to conduct a demonstration at the last minute but could not do so due to a lack of equipment or material. I have experienced that many times and even though I have many of these items hidden somewhere in some drawer, I can never seem to be able to find them.

So here is a list of items that I intend to pack into a toolbox for any teaching emergency.

Scissors
Adhesive tape
String
Copper wire (bare)
Copper wire (insulated)
Pair of wires with crocodile clips
3 Neodymium magnets
6 ball bearings
1 PVC tube
1 PVC track
Wool
3 pendulum bobs
Box of paper clips
3 balloons
2 candles
Lighter
Aluminium can
Plastic bottle
