Music with Water- We lined six glasses up next to each other and filled them with different amounts of water. The first one had a little and the last one was full. Then, we took a pencil and hit each glass of water. We discovered that the glass with the least amount of water made a low sound and the glass with the most amount of water made a high sound. We talked about how when we hit the glasses with a pencil it creates sound waves, which travel through the water. More water means slower vibrations and a deeper tone.
Walking Water- We placed three glasses side by side, filled the two outside glasses with water and food coloring (yellow and blue) and left the middle glass empty. Then, we twisted two paper towels placing one end in the glasses with water and the other end in the empty glass. After about 30 minutes we noticed that the water started to climb the paper towels making its way to the empty middle glass. We learned that this process is called capillary action and is also how flowers and plants move water from the ground up through their stems and into their petals and leaves.
