Grandparents and Special Friends Day was an exciting time in the science lab. When the students and their guests came into the lab, they found Dixie cups full to the brim with water. Everyone made a prediction as to how many more drops of water could be added to the almost overflowing cup. Guesses ranged from one drop to about 30 drops. After the prediction was made, students, and some of the special guests too, started adding water, drop by drop. It was simply amazing to see the dome of water grow to almost a quarter inch above the cup rim without overflowing. Most of the students were able to add at least 150 drops, if not more before spilling. There were many who even made it above 250 drops. This was a great way to demonstrate some of the properties of water, like surface tension, and cohesion.
The last part of the special lab had the students and their guests making paper cups by folding a square piece of paper. Many took the directions home to amaze their friends and families at the dinner table on Thanksgiving. It also saved a little on washing dishes.
I hope everyone had a wonderful Thanksgiving with family and friends!
