1. Bellringer
Choose your groups wisely- there should be no more than 4 at a table (excluding 1st period)
Take out spiral or composition notebook dedicated to Science. Use the sharpie marker on the table to write your name and “Science” on the front
On the front page (Pg. 0), write the following:
Name: _________________
Teacher: Hilgefort
Period: _____
Interactive Science Notebook: Geology
If you have not turned in your safety contract, put it in your class’ paper bind

2. Interactive Notebook When you enter the classroom:
Copy down the daily learning log (front page)
Pg 1: Density Column & Notes
Copy down homework (agendas coming soon)

3. Assigned Seats/Group Jobs
Group Manager
Voice of the group; presents information to class and keeps group on task. Tells teacher if any group member is absent.
Supplies Manager (paper manager/supplies manager)
Collects papers, manages supplies
Gameboard Manager
Moves gameboard pieces
Secretary
Picks up and puts away board/marker, writes group responses

4. DENSITY COLUMN AND NOTES
Hypothesis: What do you think will happen when we pour syrup, dish soap, water, and oil together in a graduated cylinder?
Gather Data: Observations (what happened):

5. Volume The amount of space an object occupies Base Unit= Liter
Instrument= Graduated Cylinder, Beaker
Use lowest line (Meniscus)

6. DENSITY COLUMN Material Mass (g) Volume (v) Density (m/v) Syrup15
Dish Soap 20
Water 25
Oil 10

7. Mass Mass: Amount of matter in a substance Base Unit=grams
Instrument: Triple beam balance

8. Put the balance on a
level
surface.
Slide all the masses to
zero.
If the two white lines
don’t touch,
Rotate the screw under the pan until the white lines
do line up.

9. Move the masses one at a time,
starting with the biggest one.
If the pan goes up,
you need to move the slider backward one notch
and leave it there.
Once the big mass is on the correct notch,
don’t ever move it again.

10. If putting the medium mass on 70 makes the pan go up . . .
. . . slide it back to 60 and leave it there.
Repeat the procedure with the medium mass.

11. Notice that the large and medium masses have notches on their rails.
This reminds us that we should never leave the large mass or the medium mass between numbers.
We must “click” the large and medium masses right onto the numbers.

12. Finally, slide the little mass on the front rail until the two white lines match up.
Because there are no notches on the front rail, you can slide it to the exact position you want.

13. 521.2 grams

Pg. #2: Calculating Density Lab
No homework
Take out Density Column Notes & Lab (Pg. #1)

15. DENSITY COLUMN Material Mass (g) Volume (v) Density (m/v) Syrup15
Dish Soap 20

16. What is density?

17. Density Notes Mass: The amount of matter in an object
Volume: The amount of space an object takes up.
Density- A measure of how much matter is in a certain volume or space.
Density= Mass/Volume
Objects with a lower density will float.

18. SUMMARY
Draw Conclusion: Order the following materials in order from the most dense to the least dense.
Write your claim, evidence and reasoning.
Evidence: cylinder (#1), data (#2).

19. Calculating Density Lab
Measurement Checks:
What do we use to measure the volume of liquids?
Beaker, Graduated Cylinder
What do we use to measure the volume of a cube?
Ruler: Length X Width X Height
Measure in centimeters, not inches!
Round to the nearest tenth (6.4 cm)
Each small line between the centimeters represents a tenth

20. Calculating Density Lab:
Part #2,
Write hypothesis before completing lab.
Measure the mass of the cubes by using the electronic scales.
Check them using the beaker of water by placing cubes in the water.
Do not drop the heavy cubes. Try to place them in the bottom.
Part #1
Measure the mass of the soda using the triple beam balance. Check your measurements with the electronic scale.
Round to the nearest hundredth.
When diet coke/coke lab is complete (including draw conclusion), raise hand for Ms. Hilgefort to check part #1.

23. Calculating Density Lab:
Part #2,
Write hypothesis before completing lab.
Choose 3 objects
Measure the mass of the cubes by using the electronic scales.
Measure the volume by using a ruler.
Density= Mass/Volume
Round to the nearest hundredth when calculating density.
Check them using the beaker of water by placing cubes in the water.
Do not drop the heavy cubes. Place them in the bottom using your hands.
