The boys and girls in Primary 6 had lots of fun investigating the properties of water and sound during Science week.  We investigated the effects of detergent on water through the experiment Soapy Speed Boats.  Our next experiment was Screaming Straws and as you can imagine this a lot of fun for us, but not for our teachers ears.  We looked at how we can create vibrations with air flows and these then can be changed to alter pitch of a sound.  Our last experiment was Sticky Stringy Water, we used our knowledge from the first experiment to explain how adhesion and cohesion play a part in the movement of water.
