This lab was probably the coolest lab i've ever did. I didn't know that it could be fun but at the same time a learning expirance. I learned that water is a physical combination. Also that the molecules join by polar covalent bonds. The oxygen end of the water has a negative charge and the hydrogen end has a postive charge. I also learned that water molecules are cohesive and adhesive which mean that they cling together.
string&water-I never knew that water could run down a string, i thought it was impossible. There was a little trick to getting it done, your finger would have to hold a part of the string in the breaker. After that simple thing i could get the water down the string like a pro. It was adhesive because the water was sticking the the string
water&penny-I was also suprised on the number of water droplets that could fit on a penny. The penny could hold more water droplets than alcohol.
The wax paper-the wax paper did not attract water,water drop is attracted to the other water molecules in the drop. It was cohesive because the water stuck together and wouldn't break into two.
