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 cm 3. A cm 3 is a very small measurement, about the size of a drop of water.

Tools: Tape Measure or Graduated Cylinder Measuring: The unit of measurement is cubic centimeters. Cubic Centimeter is written cm 3. A cm 3 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

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

Tools: Tape Measure or Graduated Cylinder Measuring: The unit of measurement is cubic centimeters. Cubic Centimeter is written cm 3. A cm 3 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 = ____ cm 3 The Block of wood’s volume is ___

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 283.5cm 3 Water Displacement – tool? How much does the water rise? Graduated cylinders measure milliters(ml) 1ml of water = 1cm 3, so….. 35ml=35cm 3 & 158ml=158cm 3 & 3145ml=3145cm 3

PRACTICE – Water Displacement

Person closest to the American Flag the beaker with 150 ml of water Follow my directions.

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 -

1.Which item has the most mass? 2.Which item has the largest volume? 3.What are the 2 ways to measure volume? 4.Which tool is used to measure mass? 5.What unit of measurement is used to measure volume? 6.Explain how you would measure something larger than a graduated cylinder, like the cork ball.

Tools: Math, Calculator Measuring: How much matter is inside of something.Density affects float or sink. Measuring density: Mass(g) ÷ Volume(cm 3 )= Density(g/cm 3 ) or Mass(g)Volume(cm 3 ) Density(g/cm 3 ) or Mass(g) / Volume(cm 3 )=Density(g/cm 3 )

Tools: Volume, Mass, Math, Calculator, Measuring: How much matter is inside of something.Density affects float or sink. Measuring density: Mass(g) ÷ Volume(cm 3 )= Density (g/cm 3 ) Example: Mass=3.75g, Volume=5cm g ÷ 5cm 3 =.75g/cm 3 You need to know the mass and the volume to calculate density. PRACTICE -

1.What is the volume of a book with the following dimensions? Length = 12 cm, Width = 3 cm and Height = 20 cm 2.What is the density of the book if its mass is 175 grams. 3.What is the volume of a steel bar with the following dimensions? Length = 5 cm, Width = 2 cm Height = 30 cm 4.What is the density of a steel bar if its mass is 2.5 kg? (Hint: convert to grams first.) 5.A cork ball has a volume of 5.0 cm 3 and a mass of 120 grams. What is the density of the ball? 6.Water has a density of 1 g/cm 3. If you placed the cork ball and the steel bar in water, what would happen to each? 7.Explain your answer to question #6 using your knowledge of density.
