2. Review: Matter • Everything is made of _________________. • ________________ is described as anything that has volume and mass. • Volume is ___________________________. • Volume can be measured in two ways • _____________________________________ • _____________________________________ Matter The amount of space an object takes up Direct measurement w/ ruler (cm3) Water displacement (mL)

3. Review: • You need the _________, _________, ________ of a solid regular object to find volume. • 1mL equals ______ cm3 . Length width Height 1

4. Look at the Sheet with the 3 lines • Using the cm or mm side of the ruler measure each line to the nearest mm. • Put the first line of the cm side at the end of the line on the paper. • Measure how long the line is • The line is 7.7 cm long • If you can convert your cm to mm like this • 7.7 cm = 77 mm

5. What is the length of each line?Measure in cm and mm 1. ____________cm ____________mm 2. ____________cm ____________mm 3. ____________cm ___________mm 154 15.4 6.1 61 19.2 192

18. Explain why you were able to order the blocks by density even though you only knew the mass. • You can use mass to organize the blocks because the volume is the same for all blocks. See an example… • Blocks 1,2,7,9 all have a volume of 17.6 g/cm3 so block two’s density is 128 / 17.6 = 7.28 and block nine’s density is 9.5 / 17.6 = .5 • Only the mass changes so you can organise the density by looking at only mass.
