Our kids’ science kit is filled with tools and necessary science equipment. Dollar store cookie sheets, ice cube trays and small ramekins are always used to contain mess, test liquids and sort items as well as freeze ice!

I usually always set out a magnifying glass and often a hand mirror. We use tweezers and eye droppers often as well. No kids science kit is complete without a pair of safety goggles too!
