This demonstration shows some differences between potable (drinkable) water and non-potable (non-drinkable) water. Variations in temperature, turbidity and pH level also determine the types of microorganisms that can thrive in each water sample. Continue reading
The Italian scientist, Galileo Galilei, created one of the first thermometers in the late 1500s. It was a rather simple apparatus involving a long thin tube, open at one end, and a pan of water. Students can replicate this experiment, demonstrating the principle that air expands when heated.
