  1. Friday, January 3, 2020 Welcome to the Science Extravaganza with Mr. Drez

  2. Friday, January 3, 2020 Do The 2-Minute Drill Do The 2-Minute Drill Homework is written in Blue.

  3. Today's Warmup Complete the Warm-up by Yourself Always Write in Complete Sentences • Read Page 46 • What is volume? • What tool is used to measure the volume of a liquid? • How many milliliters are in 1 cubic centimeter? • How are milliliters related to cubic centimeters? You have 5 minutes.

  4. Announcements • 3rd period • Grading your science fair journal – • Mix-It-Up at Lunch

  5. Science Fair Outline

  6. Trebuchet Catapult The distance a trebuchet can launch a golf ball. How does the mass of the counterweight affect the distance a trebuchet can launch a projectile? The mass of the counterweight

  7. Trebuchet Catapult The distance a trebuchet can launch a golf ball. How does the mass of the counterweight affect the distance a trebuchet can launch a projectile? The mass of the counterweight • 2.5 lbs = • 5.0 lbs = • 7.5 lbs = • 10 lbs = • 12.5 lbs= 5.5 kilograms 11 kilograms 16.5 kilograms 22 kilograms 27.5 kilograms The distance a trebuchet can launch a projectile

  8. The distance a trebuchet can launch a golf ball. How does the mass of the counterweight affect the distance a trebuchet can launch a projectile? Trebuchet Catapult The mass of the counterweight • 2.5 lbs = • 5.0 lbs = • 7.5 lbs = • 10 lbs = • 12.5 lbs= 5.5 kilograms 11 kilograms 16.5 kilograms 22 kilograms 27.5 kilograms The distance a trebuchet can launch a projectile • If _______________________________, then ___ _________________________________________ _____, because _____________________________ _________________.

  9. Hypothesis If ________________________, then ____________________________, because _________________. the I.V. (increases or decreases) the D.V. will (increase or decreases) research information Example If ____________________________, then __________________________ ________________________, because ______________________________. mass of the counterweight is greater the distance the trebuchet will launch a projectile will be further

  10. The distance a trebuchet can launch a golf ball. How does the mass of the counterweight affect the distance a trebuchet can launch a projectile? Trebuchet Catapult The mass of the counterweight • 2.5 lbs = • 5.0 lbs = • 7.5 lbs = • 10 lbs = • 12.5 lbs= 5.5 kilograms 11 kilograms 16.5 kilograms 22 kilograms 27.5 kilograms The distance a trebuchet can launch a projectile • If _______________________________, then ___ _________________________________________ _____, because _____________________________ _________________. • If the mass of the counterweight is greater, then the distance the trebuchet will launch a projectile will be further, because the counterweight will create more force on the sling arm.

  11. Turn your science Fair Journal in. Get out your Science Log

  12. Measuring Mass Tool: Dual Pan Balance Parts:Pans, riders, beams, adjustment knob, base, pointer Measuring: The unit of measurement is grams. A gram is a very small measurement. People usually use kilograms (1000 grams). Block of wood - ______ grams Someone’s science log – Someone’s agenda – Someone’s pencil – Test Tube - Corked Ball – Rock – Tape Measure – Stopper – Marble –

  13. Measuring Volume 2 ways of measuring volume: Length X Width X Height – tool? Measure in centimeters 9cm X 9cm X 3.5cm = The Block of wood’s volume is 283.5cm3 Water Displacement – tool? How much does the water rise? Graduated cylinders measure milliters(ml) 1ml of water = 1cm3, so….. 35ml=35cm3 & 158ml=158cm3 & 3145ml=3145cm3

  14. Volume of objects that are larger than a graduated cylinder

  15. Volume of Objects that are Larger Write at least 8 procedures on how you figured out the volume of 12 oz. can of soda.

  16. Volume of Objects that are larger 1.Obtain all materials Write at least 8 procedures on how you figured out the volume of 12 oz. can of soda.

  17. You will be practicing 2 things. • Measuring Matter – Volume • Writing Procedures for Science Fair.

  18. Volume of Objects that are larger 1.What is the volume of the soda? 1.Obtain all materials

  19. Volume of Objects that are Larger Not all objects can fit into a graduated cylinder Supplies: Towel Tape 2-Liter bottle with top cut off, filled ½ way with water. Large Beaker with 600ml of water Goal: To find the volume of a soda pop.

  20. Clean Up!!!

  21. Mass Volume = Volume Measuring Density Tools: Math, Calculator Measuring: How much matter is inside of something.Density affects float or sink. Measuring density: Mass(g) ÷ Volume(cm3)= Density(g/cm3) or Density(g/cm3) Volume(cm3) Mass(g) or Mass(g)/Volume(cm3)=Density(g/cm3)

  22. Density Questions • What is the volume of a book with the following dimensions?Length = 12 cm, Width = 3 cm and Height = 20 cm • What is the density of the book in question #1, if its mass is 175 g? • What is the volume of a steel bar with the following dimensions?Length = 5 cm, Width = 2 cmHeight = 30 cm • What is the density of a steel bar if its mass is 2.5 kg? (Hint: convert to grams first.) • A cork ball has a volume of 5.0 cm3 and a mass of 120 grams. What is the density of the ball? • Water has a density of 1 g/cm3. If you placed the cork ball and the steel bar in water, which would float and which would sink? • Explain your answer to question #6 using your knowledge of density.

  23. Density Blocks

  24. Density Blocks - ________________

  25. Get Ready for Lab Rules 6, 7 & 33 You'll need your science logs

  26. Supplies: Calculator - Guitar Dual Pan Balance – Mickey Mouse Density Blocks – Wayne’s World Poster

  27. Density Blocks - ________________

  28. Reflection Questions (R.Q.) • How much did the mass change for each additional block? • How much did the volume change for each additional block? • How much did the density change for each additional block? • What would be the mass, volume and density of 12 blocks? • How is density a property of matter, but not mass or volume? • How does density help identify a substance?

  29. What is the volume of a book with the following dimensions?Length = 12 cm, Width = 3 cm and Height = 20 cm • What is the density of the book if its mass is 175 grams. • What is the volume of a steel bar with the following dimensions?Length = 5 cm, Width = 2 cmHeight = 30 cm • What is the density of a steel bar if its mass is 2.5 kg? (Hint: convert to grams first.) • A baseball has a volume of 5.0 cm3 and a mass of 120 grams. What is the density of the ball? • Water has a density of 1 g/cm3. If you placed the baseball and the steel bar in water, what would happen to each? • Explain your answer to question #6 using your knowledge of density.
