1. Protons, Neutrons, Nucleus, Electrons notes (page 5)

Periodic Square Comic Assignment.

Create a six square comic.

Square 1: Title is “Atoms”

1. Go to the photographic periodic table here.  It’s the coolest Periodic Table around.

Square 2: Pick an element and click on it.  Copy the periodic square.  In the bubble, state how many protons and neutrons are in the atom.  In a little text box, put something the atom is useful for or something special about it.

Square 3 and 4: To the same for two more atoms.

Build an atom squares:

Squares 5 and 6:

1. Use the following simulation to build 2 stable and neutral atoms.

2. Create a Helium atom, and one more of your choice.

3. For each atom you make, create a square in your comic.  The text should state the number of protons, neutrons, and electrons in the neutral atom and some fact about the element.

Print it and put it in your notes!

Create a 9 square comic about electric fields:

Note, to take a picture of a simulation or anything on the screen, press Command-shift-4 and drag a box around what you want.  The image will appear on your desktop.  Use the simulations from the past week: Balloon and Sweater, Electric Field Hockey, Field Lines and Field Strength, 2D Electric Field, 3D Electric Field, Orbits, or do a google search for the image.

Square 1 Comic title: “Electric Fields” real large with the image of an electric field behind it.

Square 2. The field from a positive charge, text explaining what direction the field lines point.

Square 3. The field from a negative charge, text explaining what direction the field lines point.

Square 4. The field from a dipole (one positive and one negative charge), text should explain what a dipole is.

Square 5. Likes repel (explain it with an image and text)

Square 6. Opposites attract (explain it with an image and text)

Square 7. Rubbing a balloon against a sweater, what happens?

Square 8. Bringing a charged balloon next to a wall, what happens? (use command-shift-4 to screenshot yesterday’s simulation).

Square 9. Show the highest level you can reach with Electric Field Hockey.  Show it with Trace on and Field on.

Print your comic to Mr. Farley’s Printer and put it in your notes.

Page 3 in your notes is all about the electric field.

1. Download the Electric Field  chapter of my book here: Electric Field by Tony Farley

2. Read the Electric Field section (Section 2)  and answer the questions at the end.  Put all questions, answers, and drawings in your notes.

1. Electrostatics demonstration.  Upward lightning, Toronto Lightning storm, slo mo lightning, Tesla coils at Coachella

2. Run this simulation to answer the following questions:

1. Click the Add button to add a charge.  Draw the field with the arrows an charge in your notes.  Is the charge positive or negative?  Click Properties to see if you are right.

2. Click Add to add another charge and explain what happens.  Do they attract or repel each other?  Is the new charge positive or negative?  How do you know?

3. Reset, then add a negative and a positive charge. Do the charges repel or attract each other?  Pause the simulation when the charges are far apart from each other and draw the charges and field in your notes.  Label which charge is positive and which is negative.

4. Reset, grab the External Field arrow and have the field point to the right.   Add  a negative charge.  Explain where the charge moves.   (in the direction of the field or opposite?).  Draw a picture and write this as a statement in your notes that will help you remember it on a quiz.

5. Reset and add a positive charge.  Make the external field point to the right and explain where the charge goes.

6. Answer the following question: ______ charges move in the same direction as an electric field and _________ charges move in the opposite direction a field is pointing.

3. Static Shock!

Run this simulation to see how static shocks work.

What happens when you rub John’s foot on the floor?

What happens to the charge when you bring John’s finger near the door handle?

4. Hockey

Play Electric Field Hockey and see what level you can reach.  Draw level one in your notes, with all the charges, the field arrows, and show the path of the puck.

1. Download and read the chapter on Charge in my book: charge-by-tony-farley

2. Answer the questions at the end of the chapter in your notes.

Run this simulation and answer the following questions in your notes.

1. Click on the “Charts” tab.  Give the man 5 m/s of velocity and run the simulation.  Draw the Position vs. time graph of his motion before he hits the wall in your notes.  Title your graph “Position vs. Time of a man moving at 5m/s constant velocity.

2. Draw the velocity vs. time graph and label it.

3. What is the acceleration of a flat velocity vs. time graph like the one in #2?

4. Reset all the settings by clicking “Reset All.”  Now give the man an acceleration of 2 m/s^2.  Draw the Position vs. Time graph and title it properly.

5. Draw the Velocity vs. time graph.  What does this graph tell you about how the velocity changes.

6. Use this simulation to fin the acceleration of a woman pushing a 20kg cart with 40N of force.  Draw the dots that show her position vs. time.

7. Use this simulation to find out how long it takes a 5 m high ball to fall to the ground.  Be sure to set g = 10.

8. Use this simulation to find the angle that makes the projectile reach the furthest from where it started and what angle makes it reach the highest.  Draw the two projectile paths in your notes.

9. Use this page to draw the free body diagram of a book on a table, a girl hanging by two ropes, and an egg free-falling.

1. Scientific Notation and Gravitation Equation Notes (Page6)

2. (Page 7)

Today’s lesson uses the Newton’s Law of Gravity Calculator.

Relationship between mass and gravitational force.

1. What is the gravitational force on an apple at the surface of the earth?

2. If you increase the mass of the apple by x2, what is the gravitational force?

3. If you increase the mass of the apple again by x2, what is the gravitational force?

4. Describe the relationship between the mass of the object and the gravitational force on it.

Relationship between radius and gravitational force.

1. What is the gravitational force between a 1 kg mass and the earth, at the radius of the earth?

2. If you increase the radius by x2, what is the gravitational force?

3. Reset the radius so it is back to 6.37 x10^6 meters.  Increase the radius x3.  What’s the gravitational force?

4. Explain the relationship between radius and gravitational force.

Different masses

1. What is the force of gravity between two people who are 1m away from each other?  Is this force strong or weak?

2. What’s the force of gravity between a person and the earth on the surface of the earth?

3. What is the force of gravity between the earth and the sun at the distance to the sun?

4. What is the force of gravity between the earth and moon at the distance to the moon?

5. What force is stronger, the force between the earth and sun or the earth and moon?

6. Answer the question here and list the items in order of increasing strength.  Write your explanation for why they are in that order.

7. Answer the question here, draw the planet and spacecraft, and list the order of increasing strength.  Include an explanation for why they are in that order.

8. Answer the question here, draw the masses in their correct order, and explain how you know they should be in that order.
