The students were given a STEM activity during this unit. The challenge was to create a "flinker" using a baggie of objects. A "flinker" is a silly name given to an object with neutral buoyancy- it doesn't float or sink...it "flinks"! The objects included paperclips, styrofoam, beads, string, bubble wrap, a sponge, and other items. During the activity, students kept a tracking sheet with the design and result. They then revised the design and tried again each time. Here are the students working and some of the creations:
