Density HW

7H: complete all problems

8th grade: complete 1-4

SHOW THE SET UP OF EACH PROBLEM. USE A CALCULATOR TO SOLVE. ROUND TO THE NEAREST 10^th or 0.1

Density = Mass / Volume                                                    

FIND THE DENSITY:                                                  

1.  59.5 grams of wood with a volume of 85 cm³                  

2.  150 cm³ of plastic with a mass of 90 grams                          

3.  68 grams of mercury with a volume of 5cm³                              

4.  55cm³ of water with a mass of 66 grams                              


Mass = Density x Volume

 FIND THE MASS:
5.  900 cm3 of copper, which has a density of 8.8 g / cm³
6.  333 mL of corn oil, which has a density of 0.9g / cm³
7.  750 cm³ of rubber, which has a density of 1.3 g / cm³
8.  125 cm³ of tar, which has a density of 1.02 g / cm³

Extra Credit:

1.  The density of pine is generally about 0.5 g/cm³.  What is the mass of a 800 cm3 piece of pine? 

2.  What is the volume of 325 g of metal with a density of 9.0 g/cm³?

3.  Diamonds have a density of 3.5 g/cm³.  How big is a diamond that has a mass of 0.10 g? 

4.  A graduated cylinder is filled with water to a level of 40.0 cm³.  When a piece of copper is lowered into the cylinder, the water level rises to 63.4 cm³.  Find the volume of the copper sample.  If the density of the copper is 8.9 g/cm³, what is its mass?

HW for 3-day weekend for all classes.

1.Finish Crash landed on the moon

You've crash landed on the moon. Which of the following items will you bring? Which items will be useless to your survival?

Items you found:

•solar-powered heater

•three flash lights (with batteries)

•oxygen tank

•rain gear

•umbrella
•radio
•matches
•sunglasses
•scale
•food 

Remember: The Moon lacks (doesn’t have) an atmosphere. Also it has 1/6 the gravity then that of Earth. (so if you weigh 60lbs on Earth, you’d weigh 6lbs on the Moon)

1. Which items will be no use to you and why? 

2. Which will you take with you and why?

REQUIREMENTS:
MINIMUM of 2 paragraphs (in notebook, 15 pt classwork)

•-use all items

•-explain why they are necessary or not

•-make connections to science from your notes and knowledge!

2. FAMOUS QUOTE:

Neil Armstrong, one of the first people to land on the moon said, “That’s one small step for man, one giant leap for mankind”, when he landed on the moon.

What inspirational quote would you say if you landed on the Moon? 

Be creative and show that you put thought into your soon to be famous quote.

Data chart to graph

Use the following chart to graph Time of one orbit vs. Mass of planet 

Mass of planet is IV or on the x axis

Time of one orbit is DV or on y axis

Mass of Sun (body 1)	Mass of Planet    (body 2) X AXIS!	Time of One Orbit (planetary year) Y AXIS
*200	10	8.4
*200	1	9.2
*200	20	7.5
*200	50	6.3
*200	100	4.8
*200	200	3.5

HW Due 10/8

All classes must finish questions 1-3 on the orbit lab.
Questions if you lost your sheet

Q1. Is blue moon (body 3) circling the yellow sun (body 1) or the purple planet (body 2)?  Explain your answer.

Q2. How do the orbits of the planets change when the mass of the sun is increased or decreased?  Why?  Explain your answer with examples of what happened. Draw a diagram/model if needed.

Q3. Why does the sun (body 1) follow a circular path?  How does the path change as its mass changes?  Why? Explain your answer and/or use diagrams to describe.
