Science

Today in science class, we have been learning about conduction and convection. Period 5 we did an experiment using lighters, matches. scissors and teabags. 

Aim : To observe convection in real life.

Convection is when an object is being heated and then because it is hot it travels away from the source. 

1 : First we had to cut the top part of the teabag 

2: Then tip out the inside of the teabag

3: Then make sure the bag is standing up on the heat mat

4: Grab a lighter or matches ( Make sure to be careful when you are using them)

5: Carefully light the top of it with a lighter or matches

6 : Then after lighting it , make sure your not blowing your match out near the teabag 

7 :Then watch it increase in size and float up in the air

Distillation

Aim: To separate a solute from a solvent in a solution using Distillation.

Equipment: A solution of saltwater. conical flask, heatproof mat, a delivery tube and bung, Bunsen burner, tripod, gauze mat, retort stand, boss head and clamp, boiling tube.

Method:
         1 - Set up the equipment as shown in the diagram
         2 - Add approximately 50mL of saltwater to your conical flask
         3 - Light your Bunsen burner. Open the air hole and gently push the Bunsen under the tripod
         4 - Heat the solution until most of the solvent has been evaporated. Turn off your Bunsen burner

Hypothesis: I think that the color of the zero coke will change.

Results ( Observation) - After a while, I could see it bubbling, and the coke was turning into clear liquid and was going through the delivery tube.

Discussion : First we had a solution which was the coke, because of the heat it started bubbling, and we saw steam going up which meant it was evaporating, and the solution started going through the delivery tube, then it turned into clear liquid, which meant it was condensed.

Conclusion: The solution turned into a solvent, which was clear liquid, it changed to colorist, which means it the solution started off black and then the color changed to white.
