2. Comparing the acidity content of different brand of carbonated drinks
TOPIC
Comparing the acidity content of different brand of carbonated drinks

3. Investigation Value; Find out which is the best for us to drink.
Less acidity content can keep our teeth/body can make us less unhealthy and educates people who drinks carbonated drinks too much.

4. Scientific Knowledge;
Too much acid can cause diseases like heart failure,liver diseases and others.
The acid in carbonated drinks makes our bones weaker and more prone to breakage
Acid can weaken the enamel of our teeth,increasing the risk of tooth decay

5. Apparatus and Materials
Universal PH indicator solution
Dropper - 5x
Carbonated drinks (coke,sprite,fanta,+c,cream soda)
Watched glasses - 5x

6. Procedures
Fill the 5 watch glasses with 3 drops of universal PH indicator solution.
Then put 3 drops of one of the carbonated drink in one of the watch glass that contains the solution.
Observe the color change of the universal PH indicators.
Repeat for the other carbonated drinks.

10. Experimental Errors Analysis
Temperature of drinks
Amount of drops
Same result
Similarity of acidity regulator

11. Improvement for Errors
Use a measuring dropper for more accurate amount of drops.
Have a back up plan.
Keep them in the same environment to have the same temperature.

12. Research
“Acid in carbonated drinks makes our bone weaker and more prone to breakage”
“Acid can weaken the enamel of our teeth, increasing the risk of tooth decay”
= Acid in carbonated drinks adds flavor, it interferes with the absorption of calcium, resulting in the loss of calcium from bone.

13. Conclusion
The result of the experiment shows that coke has higher acidity than sprite,fanta,
+c, and cream soda.
The results doesn’t show any accurate result, it just shows that different brands of carbonated drink is bad for our health if we consume more.
The more we consume the more it will lead to an unhealthy diet.

14. Difficulties Faced Lack of meet ups Not much discussion among members
