Science Project -Blog Entry 6

So far I have almost finished my experiment (Results will be posted in the next Blog entry).
I have just put the plastics into the cups and now I have to wait eight hours until i can see the results. I have almost completed my science report with only the discussion, results, and conclusion left to finish.

Here is a timeline of my SRP.
Week 1 : -Away-
Week 2 : After receiving the notification I started thinking of ideas though i was unsure.
Week 3 : I decided to do my SRP on testing out if normal coke was heavier or lighter than coke zero.
Week 4 : I did my research and decided to weigh the drink. But then I didn't really find anything interesting about that because all i had to do was measure two cans, and I was done.
Week 5 : I came up with another idea to measure the two drinks. I put both drinks in water and see which would float and sink and time that.
Week 6 : -Nothing-
Week 7(Holidays) : Decided to change the experiment, and so I restarted by blog and re-thought everything.
Week 8(Holidays) : Started to work on what to do and I chose testing the acidity of soft drinks and juices.
I was inspired to do this because I visited the dentist the past week and they told me soft drinks are really bad for teeth, so I wanted to see if juices were too but in an interesting way.
Week 9 (not yet passed) : I conducted the experiments. I will record the results publish them and then submit my report.

My report
Experiment!
Aim
To test the acidity of popular soft drinks such as coke, fanta, sprite, solo and compare them to other drinks such as fruit drinks and also see the if the high acidity drinks will break down solids.

Equipment : pH paper, pH reference chart, different drinks (ranging from soft drinks to fruit drinks), container, metal, plastic.

Method
1.Pour your drinks all marked in a separate beaker.
2.Remove one strip of the pH test paper.
3.Hold one end of the test strip between the index finger and thumb.
4.Dip the test strip into the solution to be tested for about 1-2 seconds.
5.Shake off excess liquid.
3.Compare the color of the results to a reference chart.
4.Record the results
5.Repeat the experiment for all the drinks.

Experiment 2
Method
1.Pour your drinks all marked in a separate beaker.
2.Place a piece of the thin metal into the solution.
3.Wait for eight hours.
4.Retrieve the metal from the drink.
5.Observe the effects and record these in a table from no effect, minimum effect, major effect, or completely gone.
6. Repeat the experiment for all the drinks.

Hypothesis
Soft drinks will be the most acidic.

Experiment 1

Equipment : pH paper, different drinks (ranging from soft drinks to fruit drinks),
Dependent Variable : Color change then compare it on the pH paper.
Independent Variable : Type of drink.

Experiment 2

Equipment 2 : Cups, different drinks (ranging from soft drinks to fruit drinks), plastic, paper, metal
Controlled Variable : Cup, amount of liquid and material.
Dependent Variable : Effect the liquid has on the material.
Independent Variable : Type of drink, type of material

Im unsure if I should do experiment 2 though because it does look more interesting but the way of collecting the results which is basically just looking at them is not that reliable.

Research
There actually have been alot of people who have done similar experiments like to investigate teeth decay.
I have also visited a few sites and read about people using these types of drinks to corrode metal though they have left the metal for a few days with the drink.

Acidity
pH is the measure of acidity which range from 0-14 (1 being the highest).
0-7 = Acidic.
7+ = Non Acidic (Neutral).

Drinks
Soft Drinks - Coke(this can also include different cokes such as diet coke) , Solo, Fanta, Sprite,
Fruit Juices - Orange, Apple, Lemon, Tropical Punch


Things To Do.
1. Get pH paper
2. Set up the experiment (this means getting the equipment, plan the method and aim).
3. Write the report.

Question From looking at this picture It looks like fruit juices such as lemon and orange will far more acidic than the other drinks.

My science assessment will be about conducting an experiment on soft drinks to investigate the acidity of them compared to other drinks. I will find this out by a few ways (unsure really)
1. Testing the pH level of each drink.
2. I can also have a cup of each drink and place plastic in each and see what happens in 1-8hours.
This is basically my ideas so far.
