Question: What is it that determines whether an object will sink or float? Over the next several days we will investigate the properties that determine whether an object will sink or float. In the space below, describe what YOU THINK is the reason something will sink or float.

Day 1 1. Take necessary measurements of your objects BEFORE placing them in the water to test their floating/sinking behavior. Remember: To find the volume of a regular solid, multiply its length times width times height and the units are cm3. A=L x W x H When measuring with the metric ruler, round your measurements to the nearest 1 decimal place (0.1)

2. Look at your data table for a pattern in your data. What properties do all of these objects have in common? (Think carefully about the properties that might be important to each object’s ability to float.)

Graphing your results 5. Use the graph paper on the next page to plot mass vs. volume from your data table. Plot the points for things that sank in BLUE. Plot the points for objects that floated in RED.
