UV stands for Ultra Violet, and UV light is harmful to your skin if your skin is exposed for long enough. Sunscreen tends to block, absorb, or reflect UV rays, therefore protecting your skin. The strength of the sunscreen can differ, and that's why you see labels on sunscreen bottles saying "25 SPF" or "35 SPF", the higher numbers indicating stronger sunscreen for longer or more intense exposures.

How does this activity demonstrate the effectiveness and benefits of sunscreen in blocking ultraviolet light?
This activity can show how sunscreen blocks ultraviolet light by comparing protected areas with unprotected areas after exposure to UV light. If the protected areas show less or no color change compared to the unprotected areas, it demonstrates how sunscreen effectively blocks UV light. This highlights the benefit of sunscreen in preventing sunburn, skin damage, and reducing the risk of skin cancer.
If a UV ray gets into your skin then you put sunscreen what happens to the UV ray?
Nothing will happen. UV rays are reflected after putting sunscreen.
What can we use to put on our skin to protect us from the sun's harmful UV rays?
The easiest thing to do is to wear a suncream with a high SPF factor (30 or more). They contain chemicals that break down in UV light before your skin. Most of them are also white in colour in order to reflect the UV light and visible light of the sun away from your skin.
Is UV light a carcinogen?
UV light itself is not a carcinogen, but it can cause mutations in DNA that may lead to skin cancer. Prolonged exposure to UV light from the sun or tanning beds can increase the risk of developing skin cancer. It is important to protect your skin from UV light by wearing sunscreen and protective clothing.
Can UV light from stars reach through your atmosphere?
Yes, most of the UV radiation from stars is blocked by Earth's atmosphere. However, some UV light does reach the surface, which is why we still receive UV radiation from the Sun. This is why we need protection like sunscreen to prevent damage from UV radiation.

What does SPF 45 mean?
"The sun protection factor of a sunscreen is a laboratory measure of the effectiveness of sunscreen --- the higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn)."
Does water have a sunscreen in it?
When you are underwater, the UV light can only penetrate a short distance. But if you are swimming on the surface, the layer of water between you and the Sun generally isn't enough to protect you.
