SCIENCE F1 C1: 1.5 DENSITY

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

Before reads 50 mL. After we drop in the object, the new water level goes up to 60 mL. What is the volume of the blocks?

• 8 mL

• 10 mL

• 60 mL

• 5 mL

What is the volume of the two red spheres?

• 4 mL

• 6 mL

• 2 mL

• 8 mL

1 cm³ = ........mL

• 1

• 10

• 100

• 1000

If an object has a density of 0.6 g/mL and you put it into water, will it sink or float?

Density of water at room temperature is 0.99 g/mL

• sink

• float

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Helium balloons rise on earth because

• helium is less dense than air
• helium is more dense than air
• helium is cooler than air
• helium is warmer than air

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle
