This document discusses whether objects will sink or float based on their density. It explains that density is the amount of mass within a given volume, and that objects will float if they are less dense than water and sink if they are more dense than water. The document aims to determine why some objects floated and others sank through an experiment measuring objects' densities.

1. Sink or Float?

2. Which objects floated? Float: stayed on top of or at the surface of the water.

3. Which objects sank? Sink: fell to the bottom of the bucket of water.

4. Density How much mass is within a given volume? density = mass/volume *Volume and mass learned in previous science lessons.

5. Density Less Dense More Dense

6. Density Objects will sink if they are more dense than their surroundings. Objects will float is they are less dense than their surroundings.

7. Why did some objects float?

8. Why did some objects sink?
