  1. Get out your science Fair Journal and turn to page 11 Do the Warm-up Expectations

  2. Today's Warmup Complete the Warm-up by Yourself Always Write in Complete Sentences, Don’t use the Word “IT” • Page 40 of the Blue Science Book • What is a compound? • What is a chemical formula? • What is the chemical formula for sugar? • What elements are in sugar? You have 5 minutes.

  3. Announcements • Halloween Candy in the classroom (trash). • Halloween Candy – Bring some in for others. • Grade Sheet #3 – Tutoring today • Trebuchet Experiment – Research. After school. M-20 @ 4:15 • Homework • Firebird Friday this week

  4. Science Fair Journal • 3 Sections of Research • Research • Pictures • Vocabulary

  5. Research • Next 2 weeks of homework. • Fill in pages 9–23 of the Science Fair Journal. • Look in books, magazines and the world wide web. • Pages 9-23 will be due Nov. 8th. • Hypothesis due Nov. 8th.

  6. Safety Test Check!!! Open Your Science Logs to the page that says 100% on the Safety Test.

  7. 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 _______’s science log – ________’s agenda – ________’s pencil – Test Tube - Corked Ball – Rock – Tape Measure – Stopper – Marble –

  8. Measuring Volume • Page 46 in the Blue Science Book • Tools: Tape Measure or Graduated Cylinder • Measuring: • The unit of measurement is cubic centimeters. • Cubic Centimeter is written cm3. • A cm3 is a very small measurement, about the size of a drop of water.

  9. Measuring Volume • Tools: Tape Measure or Graduated Cylinder • Measuring: • The unit of measurement is cubic centimeters. • Cubic Centimeter is written cm3. • A cm3 is a very small measurement, about the size of a drop of water. 2 ways of measuring volume: Length X Width X Height – tool? Measure in centimeters

  10. Measuring Volume Get a tape measure and a block of wood. Write the wood’s length & width & height

  11. Measuring Volume • Tools: Tape Measure or Graduated Cylinder • Measuring: • The unit of measurement is cubic centimeters. • Cubic Centimeter is written cm3. • A cm3 is a very small measurement, about the size of a drop of water. 2 ways of measuring volume: Length X Width X Height – Tape Measure Measure in centimeters (cm) 9cm X 9cm X 3.5cm = ____ cm3 The Block of wood’s volume is ___

  12. 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

  13. Measuring Volume PRACTICE – Water Displacement

  14. Measuring Volume PRACTICE – Water Displacement Person closest to the American Flag the beaker with 150 ml of water Follow my directions.

  15. Measuring Volume PRACTICE – Water Displacement Write the volume of the following items. Rock - Marble – Stopper – Crayon – Marker – Candle - Test tube upside down – Test tube right side up – Someone’s pencil -

  16. Mass and Volume Reflection Questions • Which item has the most mass? • Which item has the largest volume? • What are the 2 ways to measure volume? • Which tool is used to measure mass? • What unit of measurement is used to measure volume? • Explain how you would measure something larger than a graduated cylinder, like the cork ball.

  17. 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)

  18. Measuring Density Tools: Volume, Mass, Math, Calculator, Measuring: How much matter is inside of something.Density affects float or sink. Measuring density: Mass(g) ÷ Volume(cm3)= Density (g/cm3) Example: Mass=3.75g, Volume=5cm3. 3.75g ÷ 5cm3 = .75g/cm3 You need to know the mass and the volume to calculate density. PRACTICE -

  19. Measuring Density

  20. Density of objects that are larger than a graduated cylinder

  21. Density of Objects that are Larger Not all objects can fit into a graduated cylinder Supplies: Towel,Tape and Calculator 2-Liter bottle with top cut off, filled ½ way with water. Large Beaker with exactly 600ml of water Dual Pan Balance with a 200g mass Goal: To find the density of a soda pop.

  22. Clean Up!!!

  23. 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 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, what would happen to each? • Explain your answer to question #6 using your knowledge of density.

  24. Please remain outside the M-building until Mr. Drez arrives.
