This is a 4 (step-by-step) simple science experiment stations idea related to a Material Changes Unit.
Each of them has steps for the children to follow and the appropriate questions for the students to develop their scientific enquiry skills.
The necessary materials are:
Station 1: Clips and chickpeas
Station 2: Candles and matches
Station 3: Water and Sand
Station 4: Water and oil (and something to heat them up)
This experiments check the children's understanding of the material changes topic: irreversible and reversible changes, how to predict results, separation of solutions, solids dissolved in water, heating and cooling different liquids...
