Last week we learnt about particles in the forms of solid liquid and gas. We know now that particles are made out of one hydrogen atom and two oxygen atoms. In a solid, the tiny molecules are packed tight together and vibrate when they move. In a liquid they are loosely packed and slide past each other. In gas form they are very loose and random and they bump into each other when they move. In these pictures when we are linking arms, we are a solid, when we are touching each other’s shoulders we are a liquid and when we are free we’re gas. Behaving like particles was so much fun!
