CIS Review Guide

Circuits - Parallel series; compare the current flowing into the bulb as the same as the current flowing out of the bulb.   Does a given battery always give out the same amount of current (think of series versus parallel) ? (It really depends on the resistance.  Describe a independent and dependent branch.

Leps - go online like you are doing the homeworks and click on “unit study guides” instead of homeworks.  

POM   - balancing, how does a scale work, is it balanced, how to find uncertainty.  For example a graduated cylnder reading 3.2 and an uncertainty of .2 is displaced by adding an object and the final reading is 4.5 in a graduated cylinder with an uncertainly of .1.   Given numerous readings find the uncertainty. Explain your reasoning.

Nature of science, what does it take for a law to be proven.  What does it take for a law to be disproven.

Astronomy by sight - comparing sundials, finding the altitude, finding the circumference of the earth

Rough drafts due Monday April 23

Final Drafts are due Friday April 27

The purpose of this activity is to research and present a topic that has to do with nuclear power.  The discussions we will have will examine some of the technological applications as well as social implications of nuclear physics.  Much has been in the news lately about using nuclear power.  

Possible topics include but are not limited to 

Historic perspectives – Einstein’s pugwash statement

How did Marie Curie or Einstein contribute to nuclear technology?

Cold wars impact on science education

Nuclear power plants

How do they work?

Are they safe?

What should be done with nuclear waste?

Chernobyl, 3 mile island, Japan

Nuclear weapons

How was the atomic bomb created?

What all went into the Manhattan projects

Current new ideas about the nucleus and matter

What is being done at CERN and or Fermi lab

Nuclear technology

How is nuclear technology used in medicine?

What is cold fusion and is it possible?

Make sure you use the generator function.

Run these experiements and change varables.

What varables did you change.  What happened as a result of your experiments

Describe the relationship between electricity and magnetism? (site concrete examples if needed). 

You are given some amount of liquid A in a 100 mL graduated cylinder (with an uncertainty of 0.4 mL) and you read its volume as 46.3 mL. You are also given some amount of liquid B in a 50 mL graduated cylinder (with an uncertainty of 0.2 mL) and you read its volume as 25.9 mL. You then pour liquid B into the cylinder containing liquid A (assume that no liquid is lost when pouring).  Finally, you read the level of the combined liquids in the 100 mL graduated cylinder as 73.1 mL.  (4 points)

(a)  Based on the measurements, which of the following three statements is true?

1.   The total volume of the two liquids definitely stayed the same.

2.   The total volume of the two liquids could have changed or could have stayed the same.

3.   The total volume of the two liquids definitely changed.

Explain your answer.

  (b)      Could the total volume of the two liquids have increased?  If so, what is the maximum amount by which the total volume could have increased?  Explain your answer. 

(c)  Could the total volume of the two liquids have decreased?  If so, what is the maximum amount by which the total volume could have decreased?  No need to explain your answer on this one.

Curiosity has always been an innate characteristic of humans.  Every ancient culture has an explination of astrological events.

Here is the link you will need http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=9

Keplers law lab                                                                           Name ______________

Go to Mr. Hedlund’s home page on the Edison website.

Click on physics, click on keplers law. http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=9

Use the information on the site to answer the following questions.

Part one :

1.      What are  Keplers three laws?

2   Notice how your applet reads fixed Kinetic energy.   What happens when you drag the blue arrow?

Part two : Keeplers laws

First law.  What you are seeing is an ellipse

a. Where is one focus always located (large red dot, hint read the info below the applet)?

b. What do you notice about the length of the blue line?

c. What do you think l1 and l2 means in the upper left of the applet?

d. What are some characteristics of an ellipse?

Second law -  Change the upper left to represent the second law.

How does this demonstrate newtons second law?

Third law

Create a table of different orbital periods and orbital radi

The velocity vector   is represented by the red arrow

When is the velocity the greatest?

When is the velocity the least?

--------------------------------------------------------------------------------------

Data analysis

What law does the above table pertain to? __________________________________

Create a line graph with T²  on the y axis and R³ on the x axis

Discuss the relationship between the  potential energy and kinetic energy, when is each one the greatest?  How does this relate to energy conservation?
