As the children work on their science fair projects, it was time to model the steps in a fun and engaging way. A generous colleague provided me with a few suplies and inspiration.
Day 1 - We practiced flipping , noticing and generally had some fun. The children noticed that the amount of water, where they expected it to land, force, type of flip etc. made a difference on the success of their bottle landing upright. But they were having to much fun to experiment in a systematic manner.
Day 2 - I posed the question-
How much water does it take to make it easier to flip a water bottle and have it land upright?
The experiment was to flip their bottles using two different amounts of water ( 125 ML or 1/4 full) or ( 250 ML or 1/2 full.) They were to tally the number of flips until their bottle stood upright on their desk. This data was then recorded onto a large GO chart for analysis.
I had the children record their hypothesis (smart guess ) on which amount of water would make it easier to flip & have their bottle land upright.
I then modeled the experiment step by step stopping at the class data collection & conclusion section. I recorded my data. The children were generally impressed that I could flip a bottle and have it land upright several times.
Now the fun began!
The children began filling bottles and putting their caps on TIGHTLY. ( I just couldn't stress that enough . ;-) They giggled as I exaggerated water everywhere and my stern drippy look.
I have included a few videos to show engagement, focus and shouts of excitement.
Flipping, recording and fun.
