Igneous Rock Science Kit
Learn how igneous rocks are formed from molten rock when it cools! Includes 15 rocks, educational guide, streak plate and magnifier.
These rock sets include the basics for each category. Specimens range in size from ¾" to 1" and each set includes a 1" plastic magnifier and guide. Each guide includes a key to specimens and an introductory statement about the contents of that particular kit. For the hardness kit an explanation is given along with the MOHS hardness scale; the mineral and rock kit guides give a brief explanation of their formation. If you want small, affordable kits to cover the basics, these are a great option. Specimens are large enough to see detail, and they come in a sturdy cardboard box with divided plastic tray. Storage isn't an issue in these compact kits. ~ Donna
