Presentation Transcript

• 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

DO NOW

• 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

• 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

Liquid Density 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
