Hoot Owls Grow Crystals


The Hoot Owls tried out a science experiment where they grew crystals on pipe cleaners with laundry detergent. They measured the detergent, just like “real scientists,” into plastic mason jars. Then, they twisted and bent pipe cleaners into interesting shapes that they taped to the inside of the lids. They watched as a grown up carefully added hot water to detergent and mixed it together. The Hoot Owls began creating hypotheses right away when the solution in one of the jars turned pink! They continued to hypothesize as the days went by.


They observed some pipe cleaners grew small crystals while others grew little to none. All the pipe cleaners were supposed to grow crystals…. so they might try this experiment again following a different recipe. Another teachable moment: Sometimes experiments go according to plan and sometimes they don’t, but scientists have to try and try again! #SaklanHandsOn
