It's summer!

It's time for Squeaks and I to get out our swimsuits, our cool shades, and head outside for some fun in the sun!

But I need to make some smart choices before we go outside.

I need to wear sunscreen, because I don't want to end up getting a sunburn!

Squeaks doesn't need to worry about sunburns, since he's a robot.

But we humans can get a sunburn when we stay out in the sun too long and don't protect our skin.

Even though the rays of the sun feel nice and warm, and are important for all kinds of life on the Earth, some of the rays from the sun's light can harm our skin.

Now, our skin does have something in it that helps to protect it from these harmful rays.

But sometimes, like when you're outside all day, that's not enough.

If too many of these rays reach your skin, your skin can become damaged, or hurt.
