Class 4 - Science - Electricity - Week 2

We were really looking forward to our second lesson studing electricity and circuits and started by familiarising ourselves with the component symbols we learnt last week.  We defined the scientific words used in investigations:  predict, independent variable, dependent variable, control variable, evaluate and conclusion.  Our first challenge was to make circuits using different numbers of bulbs, assessing how brightly they shone as more were added to the circuit.  Results were recorded in a table and conclusions drawn.  Following this, using shoe boxes, cellophane, black paper and the circuit components, we made sets of traffic lights.  The finished results were very impressive.
