Bones and Coke Experiment
Transcript of Bones and Coke Experiment
200 mL of 3 carbonated sodas ( for this experiment we will use Coca Cola, Diet Coca Cola, and Sprite)
Pure Water ( as a control group)
8 Chicken bones ( similar bones)
Dumbbell(10lb and 15 lb)
4 Rubber bands
The purpose of this experiment was to see the effect that carbonated sodas can have on the rigidity (capability to break in half) of bones.
If the environment in which the chicken bone is put is more acidic, then its toughness will decrease more due to the interactions between acids and bases of both solutions
Sodas are solutions that have a very low pH and are therefore acidic. This acidity can have huge effects on the composition of bones since they are mainly composed of calcium (a base). The many reactions that would take place between the acidic and basic components would change the chemical structure of the bones making them less rigid and more likely to break in half.
Label each container with the appropriate liquid.
Fill each container with 200mL of the corresponding liquid.
Record the pH of each liquid using the pH meter.
Measure and record the weight of each chicken bone.
Place 2 bones on each container.
Cover each container with the self-adhesive film and put rubber band to secure the attachment
Record data on each bone’s weight and the pH of each liquid each day for a total of three days.
Remove the bones from their container and dry them.
Attach dumbbells together with tape.
Attach the string to the dumbbells.
Attach the other end of the string to the middle of the bone.
Grab each end of the bone with your hands and raise it slowly.
Record how long it takes for each bone to break in half.
The data supported the hypothesis. The lab proved that acidic environment does affect the toughness of bones. The bones that were placed in the more acidic environments (Coke and Diet Coke) were less resistant to the 25 pounds. Therefore, the lab shows that carbonated sodas can have huge effects on bones. So, next time you are drinking a coke... think about this experiment and the effects it will have on your teeth!
