do now

Calculate the density for the following objects:

  • A ball with a volume of 10cm³ and a mass of 30g
  • A backpack with a volume of 200cm³ and a mass of 400g
  • A soda with a volume of 100mL and a mass of 100g
  • A safe with a volume of 1m³ and a mass of 2kg

liquid density

To figure the density of liquid, you use the same formula

  • Mass/volume = Density
  • You first measure the mass of an empty graduated cylinder
  • Then, you pour in the liquid and measure its volume
  • Next, you find the mass of the graduated cylinder with the liquid inside
  • Subtract the mass of the graduated cylinder from the mass of both to find the mass of the liquid
Liquid Density

Each table needs:

  • 1 Small Graduated Cylinder (smallie)
  • 1 Large Graduated Cylinder (tallie)
  • 1 Triple Beam Balance
  • Goggles for each student
  • Paper and pencil to record results
Liquid Density Lab
liquid density lab1

Everyone must wear their goggles at ALL times!

  • Do not play with the liquids – no drinking spilling, tasting, etc.
  • Do not waste the liquids – only use the correct amount
  • Any student who is not following the rules will not participate and receive a 0 for the lab

Step 1 – Measure the mass of your small graduated cylinder

  • Step 2 – Pour 20mL of syrup into your small graduated cylinder
  • Step 3 – Measure the mass of the syrup
  • Step 4 – Subtract the mass of the graduated cylinder alone from the mass of the syrup – this gives you the mass of the syrup alone
  • Step 5 – Slowly pour the syrup into the large graduated cylinder
  • Repeat steps 2-5 with the dish soap, shampoo, water, and oil (in this order!)
  • Step 6 – Find the density of each liquid

When finished, wash out your graduated cylinders and return all materials to their proper places

  • Wash your hands!
Liquid Density Lab

Liquids that have a lower density will “float” on liquids that have a higher density

  • The same is true for solids – if the solid has a lower density than the liquid it’s in – it will float!

uil listening

For the listening competition, someone reads an essay

  • You take notes
  • Then you answer the questions about what you heard
  • Selection test will be Tuesday after school
  • Sign-up sheet will be on my door
