A. Fill a bowl with crushed ice. B. Put a little coloured dye in the flask, and then fill it to the very top with cold water. Stand it in the bowl of crushed ice. C. After 15 minutes, carefully push the rubber bung into the top of the flask. You should see the coloured water in the glass tube. Mark the level of the water in the tube. D. Put the flask into a water bath and leave it for 15 minutes. E. After 15 minutes, mark the new level of the water in the glass tube. F. Divide the distance between your two marks into five equal divisions. Each division will represent 10 degrees. G. Leave your flask on the bench for 15 minutes (or until the next lesson). Mark the new level of the water. Keywords-Brownian motion, compress, contract, density, diffusion, evidence, expand, gas, liquid, mass, particle model, particle theory solid, state of matter, volume.

(ALL) Draw a picture of the arrangement of particles in each of the states of matter the write a description of the properties of that state of matter using the tick table to help (MOST) For each state of matter write a couple of sentences to describe the arrangement of particles in that state (SOME) For each state of matter explain the properties (in the ALL) using the term particles e. g. a gas is easy to compress because the particles are….
