BUOYANT FORCE AND ARCHIMEDES PRINCIPLE
PRE-LAB QUESTIONS
1. Draw a free body diagram of a hanging mass before it is
submerged in water. Make sure to label your forces.

3. Apply Newton’s second law to your free body diagram in
Pre-Lab Question 2 to solve for the magnitude of the
buoyant force.

EXPERIMENT 1: EFFECTS OF DENSITY
Data Sheet
Post-Lab Questions
, 1. Sketch and label what the arrangement of objects and
liquids in the beaker.
plastic
- Cork
washer
2. Rank the liquids and solids in order of least to most
dense and use your results to explain you reasoning.
Least dense >
->
Most dense
8) - > water - Syrup
-
Because the most dense liquid will sink down to the bottom .
3. Which of the solid materials used in this experiment
would make the best boat? Why?

4. Would it be easier to design a boat in a world with
oceans of maple syrup than oceans of saltwater? What
property of maple syrup might prevent boats from
traveling in it very effectively compared with in water?
