Develop and use a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
The South Carolina College- and Career-Ready Science Standards (2021) outcome 6-PS1-4 (Physical Sciences) for Grade 6 says: “Develop and use a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: South Carolina College- and Career-Ready Science Standards (2021).
Hot and Cold: Particles on the Move Grade 6 · partly supports this outcome
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.
- Why does food colouring spread faster in hot water? 45–60 min
Two cups, two drops, one race. Students drop food colouring into warm and ice-cold water at the same moment, then explain what the moving colour tells us about particles they can't see.
- How does a thermometer know? 50–60 min
Teams build a working thermometer from a bottle of coloured water and a clear straw, then calibrate it against a real thermometer. At the end, they explain how any liquid thermometer 'knows' the temperature.
