Materials
Student Provides:
Distilled Water
2 Clean Sheets of Paper
1 Paper Towel
1 Pair of Scissors

LabPaq Provides:

1 Digital Scale
1 50 mL Plastic Graduated Cylinder
1 Pair of Safety Goggles
1 Spatula
6 Test Tubes, 13 x 100 mm in Bubble Bag
1 Test Tube Rack, 6 x 13 mm
1 Dual Magnifier
1 Rubber Stopper
1 Marking Pencil
1 Test Tube
Remove the ‘’The Scientific Method’’ experiment bag from the LabPaq box.

Actions Taken: I opened up my LabPaw box and sorted through the equipment to find the plastic bag labeled ‘’The Scientific Method.’’

2. Remove the vials containing the six unknown substances from the experiment bag.

Actions Taken: I removed the vials and placed them on my counter in order from 1-6. I then studied the substances visually to gather what I already know about them.

3. Identify the color of each of the six unknown samples, and record the results in Data Table 1, next to the row labeled ‘’Color’’ for each sample.

Actions Taken: I visually examined each sample’s color, and then recorded the results onto Data Table One.

#1
Use the graduated cylinder to measure and transfer 5 mL of distilled water into each of the six test tubes.

Stopper the test tube with a clean, dry rubber stopper and shake vigorously.
Actions Taken: I labeled six test tubes in accordance with their respective Sample number and placed them on the test tube rack. I then placed a pea-sized amount of each sample in their corresponding test tube. Following that, I utilized the graduated cylinder to measure and transfer 5 mL of distilled water into each of the six test tubes. I then placed a rubber stopper on Sample #1, and shook vigorously to determine its solubility. I repeated this with each sample, and then recorded my results in Data Table 1.
OBSERVATIONS:
Questions
A. Which of the six measures in the experiment yielded quantitative data? What specifically about the measure was quantitative?
Answer: Volume, Mass, and Density all yielded quantitative data. They are numerical measurements that define the sample, as opposed to qualitative, which describes.
B. Which unknowns are you confident that you correctly identified? What specific test was crucial in this
