YR 4 Light Sensor
In computing children were investigating which materials block light the best using a digital light sensor.
Children investigated a range of materials and predicted which ones were going to let a lot of light through and which would be best at blocking light.
Using a light sensor on a Data Logger connected to a computer, children tested the materials and noted down the data shown on the display. We learnt that light values are recorded in Lux (lx).
From our data collected, children then created a chart to display their findings visually. From this data we answered questions and compared it to our predictions.
