Go take a bath!

We are jumping right into science this week! We have been learning about what makes an object sink and float, but we have been learning really challenging vocabulary, like buoyancy (NOT girlancy, remember!), displacement, and cargo. Talk about some of those words tonight at bedtime. If you take a bath tonight, think about those words while you are trying to make yourself float. Why can't you make yourself float? To displace means to remove physically out of a position. How much water is being displaced when you get in the tub? That means, how much water has to "get out of the way" so that your body can fit in the space where the water previously was?

If the weight of your body was lighter than the water you displaced, you would float. It would be like the weight of the water has the strength enough to hold you up. Of course, as we will continue to learn - the SHAPE of an object affects how much water gets displaced, so SHAPE is just as important as the weight of an object!

NOW, if your body was heavier than the water that was displaced when you got in the bathtub, you would sink! Think of Archimedes, a Greek (meaning from Greece) mathematician, physicist, engineer, inventor, and astronomer....and TAKER OF BATHS! He is the one who came up with the idea of displacement and buoyancy - WHILE HE WAS IN THE BATHTUB!! Think of where the world would be if he never thought of this!
