Which materials float and sink?
In this lesson, we will be investigating different materials and their properties. We will be exploring which materials float and which materials sink, then we will be making comparisons while looking at their properties. Do all hard materials sink? Do all soft materials float? You will need a piece of paper and a pencil. If you would like to take part in the experiment you will need a coin or small metal object, a cotton ball or pad, stones, a pencil and a bowl of water. Otherwise, you can watch me conduct the experiment while observing the outcomes.
