On Monday 2nd December, Sally from Watercare came to teach us about where water goes after we flushed it down the toilet, sink, bath and shower. At the end we did an experiment, where we mixed some salt into containers of water and add food colorings. Then we made a rainbow with the food colorings in a little tube by holding our thumbs at one end and the other end will not drip. Sally said that the more salt you put in, the more dense it is. It will sink if its dense. The water you used this morning might be drank by a dinosaur once!
