Mystery Powders Kit

Rental Fee: $50*

In this investigation, students gain experience with the evidence of chemical change – production of a gas, change in temperature, color change, and formation of a precipitate. Students observe that similar-looking powders can be differentiated by the way they react chemically with certain test liquids. Students then use their chemical tests and observations to identify an unknown powder. The teaching kit includes all necessary powders, most liquids, worksheets and other materials. Teachers will need to prepare red cabbage indicator solution prior to lesson (red cabbage (not pre-shredded) leaves not provided). Safety goggles are recommended and can be provided if necessary. Teachers are asked to replenish powders if used up during the lesson.
