 8 Tips for water safety.

1. Try not to run near the pools.

2. Don't kill anyone.

3. Don't drown.

4. Don’t fall off the water slides.

5. dont be silly around the pools.

6. dont fight.

7. wear proper clothing.

8. have a lot of fun.

evaporation

 Aim: to separate the solute and solvent away form he liquid

Hypothesis: the solute and solvent won't have liquid and will turn into crystal

Equipment: Copper sulfate solution, 250mL Beaker, heatproof mat, evaporating basin, element. 

Method: 

1. Set up element

2. Add 100mL of hot water to the beaker and place on the element.

3. Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, place the evaporating basin on top of the beaker. 

5. Turn on the element to 3

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming. 

7. Turn off the element- be careful not to touch, as it will be hot for a long time.

observation I could hear hissing and see the liquid turning into crystal

conclusion Yes the liquid turned into a crystal

discussion there was subsolid and when removing the liquid the solids showed

evaluation No because the water took a very long time to start bubbleing

Science experment

 AIM:

to sperate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction)

METHOD:

1. Pour approximately 50mL of copper sulfate solution into a beaker.

2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form called copper carbonate.

 

3.fold filter paper to fit inside the funnel

4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask.

 

5. we Stirred the mixture in the beaker, then carefully pour it into the funnel. 

6. Observe what happened.

we stared with clear and light blue chemicals that were both see-through, then we mixed them and they went to a non-see-through solid in the water and then we filtered them and it made a clear liquid the non-see-through part was a solid, filtering it removed the solid.

that's how you make it and the result of it and we did that yester for a "pre-test"
