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 and create a graph. Students will be guided on how to write a summary and conclusion. Word boxes and labels provided to differentiate for this grade level.
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. All supplies can be found at the grocery store.
This investigation is also available for different grade levels. The 4th/5th Grade investigation tests different waters, but students perform two trials. The 6th-8th grade version expands to an if, then, because hypothesis, 4 waters to test, and 3 trials. You can purchase them individually or the bundle for a discount.
