1 Do Now 1)What is the formula for density? 2)What is the volume of the block? 3)An object has a mass of 30g and a volume of 10 cm 3. What is the density? D= m V V = length x width x height V = 5cm x 5cm x 5cm V = 125 cm 3 D= 30g 10cm 3 D = 3 g/cm 3

3 Title: Calculating Density – Mini Lab L.O. SWBAT determine the mass, volume, and density of an irregularly shaped object.

4 Review

5 Calculating the density of an irregularly shaped object. 1.Determine the mass 2.Determine the volume 3.Calculate the density

6 Mini-Lab Part 1 - Bolts 1.Use the digital scale to find the mass of the bolt. Mass of bolt= _________ 2.Carefully pour water into the beaker. 3.Record the volume of the water. V intial = ________ 4.Carefully place the bolt in the beaker. 5.Record the volume of the water. V final= ________ 6.Calculate the volume of the displaced water. V final - V intial = ________ 7.Calculate the density of the bolt. D = m ÷ V =

7 Mini-Lab Part 2 - nut 1.Use the digital scale to find the mass of the bolt. Mass of nut= _________ 2.Carefully pour water into the beaker. 3.Record the volume of the water. V intial = ________ 4.Carefully place the nut in the beaker. 5.Record the volume of the water. V final= ________ 6.Calculate the volume of the displaced water. V final - V intial = ________ 7.Calculate the density of the nut. D = m ÷ V =
