This week we continued to build on our understanding of the three states of matter: liquid, solid, and gas. Hands on activities helped to illustrate how one state of matter can change to another: melting, freezing, or boiling. Water is the perfect example of states of matter to children because it can exists in all three different states. Our first experiment introduced a solid (ice cube) to liquid (water) change. Why the change? The children will tell you that when matter gains or loses heat it can change from one state to another, ice to water, water to ice, water to gas. In our second experiment the children not only got to find out how butter is made, but also saw a liquid turn into a solid. The children took turns shaking (agitating) cream until its fat molecules became shaken out of position and clumped together to form butter. We all enjoyed sampling the fruits of our labor spread on fresh bread.
Never underestimate your children’s interest in science and their ability to understand. In fact, ask them to illustrate how molecules in each of the three states move. I know you will all be amazed!
Make your week ‘MATTER.’
