Experiment, practical activity |
This is a simple and inexpensive practical activity that could be a useful
demonstration, or a whole class experiment.
It is designed to show that sun screens do
absorb UV. It also shows that other creams do
not, and that a very high SPF will absorb more
UV than a low SPF.
