Separating a Mixture using Evaporation:

Aim: To separate the solid from the liquid.

Hypothesis: I think it will boil and evaporate.

Equipment: Copper sulphate solution, 250mL Beaker, heat proof mat, evaporating basin, element. 

Method: 

1. Set up element
2. Add 50mL of hot water to the beaker and place on the element.
3. Add copper sulphate to the evaporating basin until it is quarter full.
4. Carefully, place the the evaporating basin on top of the beaker. 
5. Turn on the element to 8
6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming. 
7. Turn off the element- careful not to touch as will be hot for a long time.

Observation: I heard the boiling water.

Conclusion: Its gonna evaporate.

Discussion: The mixture heated up and boiled then evaporated.

Evaluation: Use a bigger object to hold it.

Safety signs

Engineering Fails to watch this video click the link

	Unlike prohibitory signs, mandatory signs tell traffic what it must do, rather than must not do. Most mandatory road signs are circular, may use white symbols on a blue background with white border or black symbols on a white background with a red border, although the latter is also associated with prohibitory signs.
	Prohibited signs:No access for unauthorized persons - Prohibited signs are safety signs which give information about prohibited behavior through a combination of geometrical form and color as well as ambiguous symbols. ... Prohibited signs are indications which forbid dangerous behaviour.
	Hazard symbols or warning symbols are recognisable symbols designed to warn about hazardous or dangerous materials, locations, or objects, including electric currents, poisons, and radioactivity. The use of hazard symbols is often regulated by law and directed by standards organisations.
