This is a practical activity from Virtual Maths where students collect information to be used in a data handling investigation. Students will need to have access to light meters, which are used to measure light readings in natural and artificial conditions at 1m2 intervals. These readings are repeated and students take the average measurement.
Readings are plotted onto a graph and the results compared against expected light levels. A table, which shows some general guidelines for lighting levels in different spaces, is available for further investigation or discussion.
There is also an example of how the light survey could be carried out. It is taken from a genuine investigation and includes a photograph and plan of the classroom being surveyed, as well as the results from the light readings which were taken and their graphs plotted in 3-D using Excel. It is a useful resource which will introduce students to the structure of the investigation they are to carry out.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
