Water Lab
Part 1: Procedure
1. Rinse your beaker. Place 25 ml of water in your beaker (there should be only a small amount of water at
the bottom of the beaker.
2. Obtain a paper towel strip. Draw a dark dot one 3 cm from the end of the strip of paper.
3. Place that end of the paper down in the beaker – BUT DO NOT PUT THE DOT IN THE WATER!!!
The dot should be just above the water line.
4. Bend the end of the paper towel over the rim of the beaker so the paper doesn’t fall into the beaker.
Analysis:
a. What happens to the ink of your dot?
b. Why does this happen (use two properties of water to explain it).
c. Use your new knowledge and explain why watering the roots of a plant can carry water up to the top
leaves.
Part 2: Procedure:
5. Fill a beaker with 200mL of water.
6. Balance a paperclip across the bent paperclip.
7. Use the bent paper clip to gently lower the normal paperclip into the water.
8. Try to get the normal paperclip to float on the top of the water.
9. Each group member should take turns floating paperclips.
Analysis:
d. Is it difficult to get the paperclip to float on the water? (Explain)
e. What property of water makes it possible to float a paperclip on the surface of the water?
Procedure:
10. After having answered the above questions, gently place 1-2 small drops of soap into the water.
Analysis:
f. What happened? And what caused that to happen?
Part 3: Procedure
11. Place 7mL of water in your small graduated cylinder.
Graduated cylinder
12. Draw a detailed view of how the top of the water looks.
8 mL
Analysis:
g. What property of water causes the water to behave this way in the
graduated cylinder?
7 mL
6 mL
