Electrical circuits

We were making electrical circuits today.
We found it challenging to make a circuit with two wires, a bulb and a battery.

After a bit of trial and error, and a lot of team work, we got our bulbs lighting!

Then it got even trickier.  Teacher took one wire from each group and now we had only one wire, a battery and bulb per group.  We managed to get these lighting too.

We have a great Bright Sparks 4 Kids set which we started to try out.

It has batteries, bulbs, buzzers, a motor, switches and lots of wires.

We are looking forward to trying out all sorts of interesting circuits with this kit early next week.

We will also be learning about electrical safety. 

We also talked about static electricity and we showed this in action using a balloon.

When we rub the balloon off our hair, we can then use this balloon to pick up pieces of tissue.

This works using static electricity and works well with a biro too.

We also had a chat about lightning and the dangers of electricity.

We will be very careful with the lights on the Christmas tree.

We were able to get our bulb to light by connecting the two foil sings with a metal spring and then including the angel in our circuit.

We discovered that scissors, tinfoil and some other metals are good conductors while plastic, cardboard and candy sticks are insulators and won't let the bulb light if we put them into the circuit.

We looked at how a lighthouse might work, and also at how flashing bulbs work.

Flashing bulbs would work very well in a light house.

We had a look at how an electric quiz works, though we didn't have time to make our own quiz.
