Water Tension and other Water Experiments

We were investigating water in Discovery Time today as this week's sound of the week was "W".

 Water tension - how many drops can a cup really hold?



Water and air
">We tried to see if molecules of air could stop paper from getting wet.
What we needed:
Small Glass
A screwed up ball of paper
Glass bowl filled with water

What we did: Put the paper in the bottom of the glass then turned the glass upside down over the bowl and lowered it in to the water. We then lifted the cup straight up out of the bowl and took the paper out.

Water going up hill! (Absorption)


It was interesting to observe that clear water travelled up to paper towel first
