Explore crystal growth with this hands on investigation. Great for teaching variables. NGSS aligned for Structures and Properties of Matter. Students will use the scientific method to answer the question: Does the type of water affect the mass of borax crystals created?
Included in the 15 page download:
-Teacher background information
-NGSS Structure and Properties of Matter Alignment
-NGSS Science and Engineering Practices
-6 Page Student Investigation Journal
Students will test to see if different waters affect crystal growth. Students will create a supersaturated solution. They will discover that distilled water is a pure substance and other types of water may not be. In the investigation the students will create a hypothesis. They will record data, calculate the mean, and graph. Students will be guided on how to write a summary and conclusion.
Teachers will love the step by step directions and journal layout. Students will enjoy seeing the crystals form. This is a great activity for science fairs, classrooms, clubs, or science camps. I used this to help my students prepare for the You Be the Chemist Challenge
