Get ready for a rockin' adventure with Mini Me Geology's Mineral Observation, Hardness, and Streak Testing Kit! This kit will turn your kids into mineral experts in no time and make geology fun and exciting. Your little rockhounds will be able to test the hardness and streak of eight mineral samples from the Mohs Hardness Scale, and the included hand magnifier will let them see each sample up close.

With information brochures revealing the details of each mineral and teaching the kids how to test for hardness, streak, and focus the magnifier, this kit is perfect for scouts, schools, homeschooling, and young geology enthusiasts. Kids will have hours of fun learning about the fascinating world of minerals, and parents will love watching their little ones' minds expand and curiosity grow.

Each Kit Includes:

• Eight large mineral samples: Talc, Gypsum, Calcite, Fluorite, Apatite, Feldspar, Quartz and Corundum,
• Mini Me Geology Hand Lens with 3x and 6x magnification,
• White streak plate,
• Black streak plate, and
• Information brochures teach you about your samples and how to perform each test.

Mineral Observation
The hand lens with 3x and 6x magnification helps you see the samples closely while you explore the world of minerals. To examine the minerals, look through the larger, 3X, area of the hand lens first. This section magnifies the sample to a size three times larger than actual. If you want to see part of the sample even more closely, use the smaller, 6X, area which magnifies the sample to six times its actual size.

Mineral Hardness
Mineral hardness an important key in the identity of a sample. Friedrich Mohs, a German geologist, developed the Hardness Scale in 1812. The Mohs scale is a relative scale which lists the hardness of 10 common minerals. Talc, #1 on the scale is the softest and diamond, #10, is the hardest. Other common household item have also been assigned to the hardness scale such as glass, fingernail and penny. The information cards in the kit include a copy of the Mohs Hardness Scale and instructions on how to use the minerals and household items to determine the hardness of each sample. Hint: each sample has a different hardness.

Mineral Streak
Mineral streak is the color of the sample in powdered form. Usually, you use a white streak plate for dark minerals and a black streak plate for light-colored minerals. As you scratch the mineral across the plate, a small portion will break apart and form a powder on the surface of the plate. This powder color is the streak. Often, the streak is the same color as the mineral; however, sometimes the streak color is different than the outward appearance of the mineral which is a great clue to the mineral’s identity.
