1. The volume of the block of wood = 5.00 L.
How large is the volume of the block of wood in dm3.
2. Calculate the density of the block of wood.


At the top left, select Material: Ice.
3. Calculate the volume of the ice in dm3.
4. Show with a calculation that the mass of this ice block is 4.6 kg.


Select top left behind Material: Styrofoam.
5. Use a calculation to show that the polystyrene volume is 5 dm3. Use the density indicated in the applet in your calculation.


At the top right click on: Same mass.
The four blocks all have the same mass.
6. Why are the four blocks the same weight, but not the same size?
7. Which block do you think has the highest density: the yellow or the red block? Explain your answer.


At the top right click on: Same volume.
The four blocks drawn are the same size, but not the same weight.
8. What do you have to do to determine the density of the yellow block?
9. Calculate the volume of the yellow block.
10. Calculate the density of the yellow block.

11. Calculate the volume of the red block.
12. Calculate the density of the red block.


At the top right click on: Same density.
13. Calculate the density of the green block.


Click at the top right on: Mystery.
14. Calculate the density of the yellow block (A).
15. Calculate the density of the red block (D).
