Equipment Demo of distillation Slide 2 printed if needed (helpsheet)

The water evaporates and forms steam. The solute does not evaporate. The mixture is heated. The water runs into the beaker. The cold water flowing around the outside of the condenser cools the steam. The water vapour passes into the condenser The steam condenses to form pure water The water evaporates and forms steam. The solute does not evaporate. The mixture is heated. The water runs into the beaker. The cold water flowing around the outside of the condenser cools the steam. The water vapour passes into the condenser The steam condenses to form pure water The water evaporates and forms steam. The solute does not evaporate. The mixture is heated.

Retrieval practice 1) List the properties of solids 2) What is the difference between chemical and physical changes 3) Describe the change of state ‘melting’ in terms of closeness, arrangement and motion of particles 4) Define solute, solution, solvent

What equipment can you name? TWWL: about distillation SO THAT I CAN… State names distillation equipment Describe how to use distillation equipment to separate mixtures Explain how distillation works with your own design 13/07/2017 What equipment can you name? Energy and direction

Distillation Watch the demonstration of distillation Make notes on your mini-white board as you will need to remember the steps later Helpsheet if needed

Annotate your diagram to show the steps 1-5 The water vapour passes into the condenser The steam condenses to form pure water. The water evaporates and forms steam. The solute does not evaporate. 5 3 2 1 4 The mixture is heated. The water runs into the beaker. 6 The cold water flowing around the outside of the condenser cools the steam.

Using Distillation In pairs on your mini white board Make a sketch of how you could use the following equipment to get clean water from dirty water on a desert island Plastic sheet Metal cup Plastic tube Matches Twigs/branches Plastic pipe Handkerchief
