As mentioned in the previous post, we have been exploring two words: Â “level” and “balance.” To expand on our exploration of level and balance, the children tried their hand at balancing bubbles…
Each child filled up a clear plastic tube with water making sure that the water level was almost at the very top of the tube. Then they added a lid to the tube to keep the water sealed inside…
Because the tubes were not filled all the way to the very top, a small pocket of air was left in the tube which created a bubble in each child’s tube.  The more air that was left inside, the bigger the bubble (air pocket) but the goal was to have a little bubble so we needed to try leave the smallest amount of air inside  the tube as possible…
Once the children had filled their tubes with water and put the lid on tight, then each held their tube sideways and tried to  get the bubble that was inside the tube to balance in the middle by tilting the tube from side to side…
Getting the bubble to balance in the middle was a challenge for our students. The task required using gentle and slight tilting movements, a steady hand, and keeping a close eye on the bubble…
Not only was this an interesting exercise for the kids to explore, but the process gave us the opportunity to reinforce lots of scientific and engineering terms such as tilt, balance, level, middle, side, top, bottom, air, water, bubbles, air pocket, and steady. The process also promoted the use of eye-hand coordination and fine motor control in a rather unique way…
