Is water sticky? - Surface tension SCience Lab

Here students practice the steps of the scientific method during this hands-on lab. Students formulate hypotheses about which coin will hold the most drops of water . Next, students tried to answer the following question: 
* So why does a dome form when you drop water on the coin?
•  And why does the dome eventually collapse? 
​• What allows those cool water bugs to walk on water?
Finally, students learn about surface tension and how water molecules  hold tightly to each other.
