Hi everyone! Well done on all your hard work doing STEM activities so far. This week we are looking at density. Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density. This video will show you how it works! Try it out at home too see if you get the same results. Feel free to experiment with different liquids, good luck!
