Crystal Growing Rock—
Student Laboratory Kit
By: The Flinn Staff
Amazing! When a limestone rock is placed in a solution of acetic acid, beautiful popcorn-like crystals actually grow out of the rock. In this activity, students place a limestone rock in a weighing dish with acetic acid and allow the contents to sit undisturbed for a week. The result is a delicate, coral-like covering of white calcium acetate crystals on the exposed rock surface. Use this fun crystal-growing activity to teach students about chemical reactions and the properties of acids and bases. Includes student procedure and Notes, acetic acid solution, reusable limestone rocks, and weighing dishes.
Complete for 30 students working in pairs.
Microscale Silicate Garden—
Super Value Kit
By: John Mauch
Southridge H.S., Kennewick, WA
Your students will love to grow their own silicate crystal garden in microscale test tubes! In this kit, the crystal growing ability of 11 different metal salts in sodium silicate solution will be contrasted and compared. Students will be amazed by the beautifully colored crys- tals that sprout from the bottom of their test tubes in only a matter of seconds. A great kit to introduce the scientific concepts of solubility and chemical reactions. Includes eleven metal salts, sodium silicate solution, detailed background information, and instructions.
Super Value Kit is complete for 5 classes of 30 students.

The Crystal Forest—
Student Laboratory Kit
By: The Flinn Staff
A new twist on crystal growing! In this activity, students cut out and assemble miniature paper trees. The trees are placed in a solution of Prussian blue, sodium chloride, and ammonia. Overnight the trees become “snow-covered” in a thick, delicate envelope of salt crystals. This beautiful white forest is sure to be a favorite. Includes detailed instructions and a reproducible student worksheet.
Complete for 30 students, each making one tree. Super Value Kit is complete for 5 classes of 30 students.
