Homework for tonight:
8th Grade -  Unit 2 Machines: Student Information - read and answer questions on the reverse side.
6th Grade -
period 2 - answer the problems on the "Reading Volume and Density" worksheet; and practice using  a triple beam balance for yourself using the simulation found at http://www.ohaus.com/input/tutorials/tbb/TBBread.html.
Period 3 - answer the problems on the "Density" worksheet (back of reading volume sheet done in class); and practice using  a triple beam balance for yourself using the simulation found at http://www.ohaus.com/input/tutorials/tbb/TBBread.html.
Density problems:
Homework for tonight included reading graduated cylinders (which I can't' duplicate here and the following density problems): Density = mass divided by volume. Units of measurement include grams for mass, cubic centimeters or cm3 for volume, and combination for density g/cm3.


1.The mass of a block is 275 grams and the volume of the block is 25 cm3. What is the block's density?

2. The volume of a rock is 5cm3 and the mass of the rock is 35 grams. What is the rock's density?



To find Volume of a regularly shaped object :

Length x width x height = L x W x H (no problem here; use this for problem 3)

3. A cardboard box has a length of 3 cm, a width of 2 cm, and a height of 2 cm. The mass of the cardboard box is 48 grams. What is the density of the cardboard box?
