Chemistry, the particulate nature of matter: the properties of solids, liquids and gases in terms of the particle model, including gas pressure.
The National curriculum in England: science programmes of study, Key Stages 1–3 outcome for Years 7–9 says: “Chemistry, the particulate nature of matter: the properties of solids, liquids and gases in terms of the particle model, including gas pressure.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson.
Hot and Cold: Particles on the Move Grade 6
Why tires go soft in winter, why sidewalks have gaps, and how a thermometer knows. Five lessons on what heating and cooling do to the particles in everything around us.
- Why do bike tires go soft in winter? 45–60 min
Students stretch a balloon over a bottle, move it between warm and ice water, and find out what happens to air particles when they cool down. Then they explain a cyclist's 'flat' tire on the first cold morning.
