Students experimented with how many drops of water a penny could hold. Many of them were very surprised with their results! The discovered that water likes to "stick" to itself and can be "stickier" than other liquids, such as coffee.
Here students did an experiment to test how fast water was able to climb up different materials. The materials tested were cloth, newspaper and paper towel. They discovered that water traveled up the paper towel the fastest because the paper towel gave water the most room in which to travel.
Students also discovered that the solid form of water, ice, is actually lighter than the liquid form - which is not true for most other types of matter (a frozen cube of olive oil quickly sank to the bottom of liquid oil). They also discovered that water is heavier than oil because it sank to the bottom of the oil. Some students found this puzzling because they assumed the "thicker" substance would be heavier.
