Our UFO Ball and How it Works

We have a UFO ball in our class.  When Mrs Chrystall gave it to us we were amazed and didn't know how it worked.  We asked lots of questions about it.

We really wanted to know what it looked like inside so Mrs Chrystall carefully cut away some of the plastic.  Before she did this we had to PREDICT what it would have inside.  We thought it would be a circuit with a battery, wires, a bulb and a buzzer. 

We can now see inside our UFO ball and it still works.  We were right about it having a circuit but we were surprised at how the circuit looked.  We learnt a new word too - soldering.  Soldering is when the metal is melted onto the circuit board to connect the wires.
