PhET Density Lab

Dive into density with the PhET simulation! Calculate mass, volume, and density.

PhET Density Simulation Go to the Intro: Fill in the blanks using information from the simulation. For the wooden block put the mass at 2.00 and fill out the information belowMass = 2.00 kg Volume = 5.00LDensity = 0.40kg Is there a relationship between the volume of water displaced and the total volume of the block that has anything to do with density? If so, what is it? Manipulate blocks , use different materials, in the custom setting to find out the answer. When objects float , they displace an amount of water equal to their mass volume density When objects sink, they displace an amount of water equal to their mass volume density What is the density of water? Look it up online 1 g 2 kg 0.5 kg Go to Part 2: Compare Now with the button clicked for “Same mass” fill in the following table: Use two decimal places for each number. Color Mass (kg) Volume (L) Density (kg Volume of water displaced (L) Blue 5.00 5.00 1.00 5.00 Yellow 5.00 10.00 0.50 5.00 Green 5.00 2.50 2.00 2.50 Red 5.00 1.25 4.00 1.25 Now with the button clicked for “Same Volume” fill in the following table: (set it to 5 L) Use two decimal places for each number. Color Mass (kg) Volume (L) Density (kg Volume of water displaced (L) Blue 6.00 5.00 1.20 6.00 Yellow 8.00 5.00 1.60 8.00 Green 4.00 5.00 0.80 5.00 Red 2.00 5.00 0.40 5.00 Now with the button clicked for “Same Density” fill in the following table: Use 0.80 as your density Use two decimal places for each number. Color Mass (kg) Volume (L) Density (kg Volume of water displaced (L) Blue 3.00 3.75 0.80 3.00 Yellow 4.00 5.00 0.80 4.00 Green 2.00 2.50 0.80 2.00 Red 1.00 1.25 0.80 1.00 Is the relationship between mass and volume proportional? Explain your thinking.
