2. Bell Ringer Read p 65 Answer question #4 on page 67
What is the density of a 25-g sample of silver if a 5-g sample of silver has a density of 10.5g/cm³? Explain.

3. Classroom Greeters Automatically get up and shake visitor’s hand
Introduce yourself and the teacher/class
Quietly, “Hi, my name is ________. This is 6th grade science. Our teacher is Ms. Edmonds.”
Hand the visitor the lesson plan and worksheets or directions for the lesson
“We always have an agenda on the board that tells us the objective and activities. We begin with a bell ringer, watch videos, read, play games, or take notes during class, and write a DFA about what we learned at the end of class.”
Explain what the class is working on
Thank the visitor for coming and Go sit back down
“Thank you for visiting us.”

4. Density (Revisit) What two properties do we need to find density?
How do we measure those two properties?
Sometimes we’ll have to use another way….

5. Volume Can be found using a graduated cylinder
Can also be found by using the formula
V= l x w x h

6. Volume Examples

7. Mass and Volume Relationship
You need to know mass and volume to find density
Compare the density of objects to the density of water
If the mass is greater than the volume, the density will be _______ than 1 and the object will ________.
If the mass is less than the volume, the density will be _________ than 1 and the object will ________.
On the back of your homework….
