Ed Dancing raisins activities. Lots of fun experiments. I have done this experiment, and seen the entire class become silent out of curiosity. It is a great engagement piece for a lesson, and it can be hands on if you ask for volunteers!
Try the amazing classic science experiment: Magic Milk!
Make a rainbow paper craft that changes colors as the paper is tipped back and forth in sunlight! Create gorgeous rainbow patterns and designs while teaching children the basics of thin film interference. Add this rainbow paper experiment to your list of simple experiments for kids and creative art and STEAM projects!
