Today in our science lesson, we acted like scientists and investigated how the sun affects special beads that change colour when they meet UV light. We also tested if sun cream works. To do this, we used UV beads and put different factors of sun cream on them. Then we went outside to see how the beads reacted when the sun touched them. This showed us that the sun gives us energy, but it can also be bad for our skin if we don't protect ourselves. Too much sun can give you a sunburn. The beads without sunscreen changed color, the ones with lower factor sunscreen changed a bit, but the ones with factor 50 stayed the same color, showing that they were well protected.
