Kinetic Theory, States of Matter, Change of State and Separating Mixtures Escape Room for Middle School

Finish and reinforce a  middle school module on states of matter, change of state, mixtures and separating mixtures or revisit it prior to exams with this innovative, enjoyable and challenging escape room lesson.

Students must work their way through the clues to find the code to a combination lock on the school storeroom where Chomper, the school guinea pig has been accidentally locked.

Prior Knowledge Required

> Three states of matter are solid, liquid and gas.

> Arrangement of particles in solids, liquids and gases.

> Properties of solids, liquids and gases in terms of the arrangement of their particles.

> Change of state including sublimation.

> Pressure in gases and the effect of increasing the number of particles and temperature and decreasing volume.

> Diffusion.

> Elements and compounds are pure substance and mixtures are not.

> Meaning of the terms solute, solvent,  solution, soluble and insoluble.

> Particle theory to explain why stirring, temperature and particle size affect the rate of dissolving.

> Particle theory to explain dissolving, suspensions and saturated solutions.

> Extracting information from solubility curves.

> The composition and physical properties of mixtures

> Evaporation to dryness and crystallisation

> Distillation

> Fractional distillation

> Filtration

> Chromatography

The pack contains:

> PowerPoint – scene setting and instructions (sound effects and built-in timer);

> crossword;

> word search;

> dominoes activity;

> worksheet;

> code breaker sheet;

> answers;

> lesson plan.

If time is limited just the crossword, word search and domino can be used. The worksheet is the most challenging clue to solve and this can be omitted completely for less able classes.

Both 3 and 4 number combination locks can be purchased very cheaply online or the teacher can pretend to phone the school office for the staff to attempt to release the guinea pig
