1. VERY IMPORTANT DENSITY FACT DENSITY IS A PROPERTY OF A GIVEN SUBSTANCE. NO MATTER HOW MUCH OR HOW LITTLE OF THAT SUBSTANCE YOU CONSIDER, THE DENSITY OF THE SUBSTANCE WILL ALWAYS BE THE SAME. ONCE THE MASS OR VOLUME IS CHANGED WHILE THE OTHER STAYS CONSTANT – THE DENSITY WILL CHANGE THUS CHANGING THE OBJECT!!!!!

2. What floats your boat? Water has a density of 1g/cm3 For something to FLOAT it must have a density less than that of water (< 1.0g/cm3) For something to SINK it must have a density greater than that of water (> 1.0g/cm3)

3. DENSITY AND FLOATATION Which object has the LEAST density? Which object has the MOST density?

4. High Density/Low Density Pizza

5. Which do you prefer?..This?

6. Or this?

7. The Great Debate: Diet vs Regular Cola

8. Lab Experiment Place each can on the triple beam balance. Record the mass (REMEMEBER TO USE GRAMS!!!) One the mass has been found of each can, PREDICT what will happen when the cans are placed within a bucket of water. (Will they both float, sink, each do their own?) AFTER you make your prediction, place cans within the water carefully and observe what happens! Record data. Repeat the same steps for a lemon and lime.
