Contractions/Implosions

In Science we have been doing an experiment involving making a can crush itself.

Aim: To observe contractions in gases.

Hypothesis: The can will IMPLODE!

Equipment: Bunsen burner, Scissor tongs, Ice cream container, Used soda can, Gauze mat.

Method:

1. Set up your bunsen burner
2. pour apox 50-60 ml of water into the can. it should be no more than 1/4 full.
3. heat the can of water until steam is escaping from the top.
4. carefully grip the can with the tongs. be sure to have a strong grip on it before lifting it off.
5. Quickly but very carefully invert the can as you plunge it into the container of cold water.

Distillation Experiment

In Science we are doing an experiment involving boiling coke to see what is left behind.

Aim: Separate the solute from the solvent in stevia coke.

Hypothesis: That the coke will leave a strangely colored liquid and some crystals.

Equipment: Stevia coke, 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 equipment as shown in diagram.
2. Add approximately 50 mL of coke to your conical flask.
3. Light your bunsen burner. Open the air hole and gently push the bunsen burner under the tripod.
4. Heat the solution until most of the solvent has evaporated. Turn off your Bunsen burner.

Results/Observations: The coke boiled very quickly and not a lot of crystals were left. The liquid was clear.

Conclusion: My hypothesis was completely wrong for the results were the opposite to my hypothesis.

Discussion: The liquid was clear and there weren't a lot of crystals because stevia coke is made up of mainly liquid ingredients.

Evaluation: My experiment was a success, I was able to separate the solute from the solvent in stevia coke (even if there wasn't much solute). If I did it again I would use a different type of coke.
