| What 2 variables does density represent? | mass and volume |
| 1 unit of meausrement for mass | grams |
| 1 unit of measurement for volume | mL |
| 1 unit of measurement for density | g/mL |
| In the presentations of density, why did the diet soda float | The diet soda floated because the diet soda is less dense than the water. It is less dense than the water because it has less sugar than regular soda which results in a lower mass |
| What is the formula for density | MASS divided by VOLUME |
| 1 other measurement for volume | cm squared |
| 1 other measurement for density | g/cm squared |
| What is the density of a piece of pine wood with a mass of 200g and a volume of 10cm squared? | 20g/cm squared |
| Why did the bubble float? | The bubble floated because the bubble was less dense than the carbon dioxide it was on and the carbon dioxide was there because of the baking soda and the vinegar |
| If aluminum has a density of 2.7g/mL, what is the mass of 5mL of aluminum? | 13.5g |
| What is the density of water? | 1.0g/mL |
| Why is sea water denser than regular water? | Sea water is denser than regular water because sea water has more mass than regular water |
| Which would occupy more volume 10 grams of tin(density =5.6g/cm squared) or 20 grams of aluminum (density= 2.7g/cm squared)? | 20 grams of aluminum |
| Which one has more mass, 10 grams of feathers or 10 grams of brick? | 10 grams of feathers and 10 grams of brick are the same |
| Which one has more volume, 10 grams of feathers or 10 grams of bricks | 10 grams of bricks |
| A person finds a gold looking rock in their backyard. It has a mass of 19.3 grams and a volume of 2 cm squared. Is this substance gold? | No because gold has a density of 19.3, not a mass of 19.3 |
| How many milliliters does 1 cm squared equal? | 1 mL= 1cm squared |
| Describe how volume can be measured using water displacement | Just like Archimede did, fill up a tub of water to the tippy top and then place the object in. Get the water that was taken out of the tub as a result of the object and put it in a graduated cylinder and measure it. That will give you the volume if the object. |
| How would you measure the volume of a rectangular block using a metric ruler? | Measure the length, height, and width and multiply them together to get the volume of the object. |
| On a mass-volume graph, what does density and slope have in common? | Density and slope are the same measurement on a mass-volume graph. |
