SATURATION LABPurpose/Testable Question:

Which of the three chosen substances will saturate first when dissolved into water Gatorade (mix), Lemonade (mix), or Kool-Aide (mix)? Hypothesis:

We predict that the lemonade mix-solution will saturate first in the water.

Identification of Variables:

Independent Variable 100ml of water

Dependent Variable Gatorade, lemonade and Kool-aide mixtures

Controlled Variables adding .5 grams of any chosen substance into the water solution. Apparatus:

-3, 300 ml Beakers

-Gatorade powder mix

-Lemonade powder mix

-Kool-Aid powder mix

-400g Balance

-Stirring Rod

-Metal Scoop

Method:

1. Weigh each beaker in the Balance and record its weight

2. Fill each beaker with 100ml of water.

3. Then record the weight of the beaker with water using the Balance Scale, subtract the weight of the beaker from step 1, in order to obtain just the weight of the water (you will need to know the weight of both beaker-and-water for the final steps, so dont just press TARE).

4. Measure 1 gram of the chosen mixture (Gatorade, Lemonade, or Kool-Aide) with the Balance

5. Add one gram of the chosen mixture into one beaker.

6. Stir and mix the water solution until all of the mixture is dissolved; check if any saturation has occurred.

7. If no saturation has occurred, check and weight .5 grams of that same solution into the balance, then mix it into the water.

8. Stir the beaker until all of the mixtures has dissolved.

9. Repeat this process for each of the given mixtures (Gatorade, Lemonade, and Kool-Aid) until you observe saturation form in the bottom of the beaker.

10. After the recorded saturation has been observed, weigh the beaker one more time in the scale to record its weight before/after the saturation.

11. The weight will indicate to you the number of grams of each give solution that were needed to saturate the water

12. Take this weight and subtract it from the weight of the beaker with water before you started adding your mixture. This will indicate you the number of grams that each give solution took to saturate in the water

13. Repeat each trial 3 times to assure accuracy and clean and wash each beaker after each trial to ensure the substance inside the beaker stays pure; do not mix two different substances into one beaker.

14. Remember to do these steps for Gatorade, Lemonade, and Kool-Aid as well as do three trials for each.Safety Concerns:

There are no safety hazards in this experiment, nothing is hot enough to burn or scold, and nothing is acidic enough burn through skin tissue. GATORADELEMONADEKOOL-AID

Presentation of Results / Graphs:

Conclusion:

Based on our hypothesis, we had predicted that the Lemonade (mix) would saturate first in water. We can see from our graphs that lemonade saturated at an average of .90g/100ml of water. This was way faster than any of our other two solutions (Gatorade and Kool-Aid) who took an average of 1.90 up to 2.50 grams of the solution to saturate. We can conclude that Lemonade has the lowest saturation consistency and that Kool-Aid has the highest saturation consistency. Evaluation:

We followed our procedure carefully and made doubly sure of our measurements with each mL of water we used and each gram we weighed. We checked each data-result three times to assure precision, and accuracy. If we could do this lab experiment again it would be best to probably try different variables such as different substances to dilute into water or expand the number of trials in order to have a wider spectrum of results. _1366199063.xls
