Presentation Transcript

  1. 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

  2. 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

  3. 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

  4. 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

  5. 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 Liquid Density Lab

  6. When finished, wash out your graduated cylinders and return all materials to their proper places • Wash your hands! Liquid Density Lab

  7. Why do you think the liquids made layers? • How is density related? Liquid Density Lab

  8. 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! Liquid Density

  9. Page 55 • On scratch paper, answer at least questions 1-16 Chapter Review

  10. 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 UIL Listening

  11. Have a great weekend! For Monday
