Unearth the secrets of geology as you dig deep into the science of rocks and minerals and the crystals that form them. Through 18 hands-on experiments by Thames & Kosmos, kids ages eight and up will discover some pretty amazing things about geology, mineralogy, and crystal growing. Become a geologist-in-training as you mold your own crystal geode and grow three different types of crystals that vary in color and shape. Work with real mineral specimens to learn how to determine a mineral’s chemical properties — such as color, luster, streak color, hardness, density, magnetic properties, and carbon, sulfur, or iron content — and use your findings to identify unknown minerals. As you explore, you’ll get an overview of the geologic rock cycle and discover how the three main categories of rock — igneous, sedimentary, and metamorphic — are formed, altered, destroyed, and formed again. Whether you’re a geology enthusiast already, or just discovering this rocking science for the first time, Kids First: Crystals, Rocks and Minerals make for an unforgettable and fun educational experience.

Matte, weightless, mildly drying
Size: 3 Fl Oz (Pack of 1), Style: SPF 50, Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Very good sunscreen. It is very similar to the Neutrogena Ultra Sheer sunscreen but with less/minimal fragrance. It absorbs immediately and feels matte and invisible. The only slight downside is that the silica in the sunscreen is actually so good at absorbing oil that it is mildly drying. This is great for people with oily skin, but people with acne like myself often use retinoids that are already very drying, and this can magnify the dryness. I often follow this sunscreen with some moisturizer to counteract the drying effect.

No white cast.
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Doesn't leave a white cast on your face as long as you rub it in enough. It also doesn't break me out. Good product.

Great - effective sunscreen that isn't oily
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Works well, doesn't make your skin oily, almost disappears when you put it on. Made for faces but of course works anywhere else as well.

It is a good sunscreen, but if your skin is very oily, think again.
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have tried many, MANY sunscreens, and this one is in my top 10, but not at the very top. Why not? Well, what I like about it is that you get a good amount for an excellent price. It's lightweight, but not extremely so, and this size can easily last you 3 months without any problem. However, while it's made for oily skin, it's not that light. After just a few hours of application, it can leave your skin feeling greasy, especially if you sweat easily. It doesn't leave a white cast, but it does leave a slight, shiny finish. Reapplying isn't very comfortable. If you use it just once a day, it's fine, but if you apply it more often, your skin will feel a bit heavy and oily. I think this sunscreen is better for specific occasions rather than for daily use. If I had to choose a sunscreen for daily use, I would pick one with a lighter formula, like Fusion Water from Isdin.
