Today in science

  • What method would I use to find the volume of a plastic toy “Agent P”? Why?

  • What kind of math problem is required to find displacement?

  • What metric units are used to represent mass?

  • What are 3 equivalent formulas for finding the volume of a regular shaped object?

  • What are 3 equivalent units for volume in the metric system?

  • If you have 15 cc’s of H2O2, how many milliliters is this?

  • What does dm stand for?

  • What form of matter can be made up of a crystal lattice?

  • Which form of matter is more energetic, plasma or gas?


Summary

Summary “Agent P”?

At the end of your Cornell Notes for Physical vs. Chemical:

1) Tell what the difference is between Physical & Chemical Changes…..or how can you determine whether a substance has gone through a physical or chemical change?

2) Why is density an effective way of identifying a specific type of matter?


Today in science

Intro to Density “Agent P”?

How tightly packed the particles are in a substance.

vs.

1. What is mass effected by?

A block of iron has very tightly packed compared to aluminum.

2. Will changing the volume change the density?

NO. Density is a RATIO between mass and volume….the particles remain packed the same way no matter what the size of the sample.

3. What are three ways to find volume? “Agent P”?

  • Use a G.C.

  • bxh

  • displacement

Yes. You will have more particles so mass will increase. BUT the density is the same.

vs.

4. Will changing the volume change the mass?


Finding volume
Finding Volume “Agent P”?

  • The length is 3 cm the width is 4 cm and the height is 5 cm.

  • The length is 4 dm, the width is 6 dm and height is 9 dm. The volume is?

  • The length is 10 m, the width is 4 meters the height is 7 meters. The volume is?
