pHet Earth Science
Run Now.
Copy and paste this into a new post and answer the questions as you do the activity.
PhET: Plate Tectonics
Go to the PhET website
Select the Plate Tectonics Simulation
Spend a few minutes exploring the
simulation. Don’t worry, you can’t break
it.
Select
the “Crust” tab at the top of the simulation.
Under view select “Both”.
1) What are the 3 variables that can be changed in this simulation? (Scale or zoom is a nice feature, but not a
variable.)
1.
3.
2) Try to duplicate the continental crust as
accurately as possible. How did you set
temperature:
composition:
thickness:
3) Try to duplicate the oceanic crust as
accurately as possible. How did you set
temperature:
composition:
thickness:
4) In terms of the three variables you have
investigated, describe how continental crust differs from oceanic crust.
Select the “Plate Motion” tab at the top of the screen. Under view select “Both”.
8) Investigate convergent boundaries (green
arrows). Report your findings in the
following table:
Left Side Crust
|
Right Side Crust
|
Which Crust is
Denser?
|
Which Crust
Subducts?
|
Do non-volcanic
Mountains Form?
|
Does a Trench Form?
|
On Which Crust Do
Volcanoes Form?

9) Describe the relative motion of the
plates at ALL convergent plate boundaries.
10) Three
times you used the same two types of crust, but switched left and right
sides. What do you observe about the
results? Is the side the crust is placed
on important?
11)
Look
for patterns in density, subduction, and volcanoes in the table. When volcanoes form, on which plate do they
always form?
12)
Explore
how a continental-young oceanic crust collision differs from a continental-old
oceanic crust collision.
Describe the difference in the angle of
subduction between old and new plates.
How does the distance between the
volcanoes and the plate boundary differ between old and new plates?
13)
Investigate
divergent boundaries (red arrows). Click
show labels. Describe the relative motion
of ALL plates at divergent boundaries.
14)
What
is generated at ALL divergent plate boundaries?
15)
Investigate
transform fault boundaries (blue arrows).
Describe the relative motion of ALL plates at transform fault
boundaries

Why are the bads bad and What is good about the following Bads?
1. Bad:
We see the Space Shuttle in orbit ....and we hear the sonic booms from the Shuttle as it passes overhead. They wind up landing in the extensive LA drainage basins.

1. Bad:

2. Bad: Premise: The Earth's magnetic field is collapsing,
and the field is what's protecting us from deadly cosmic rays and microwave
radiation from space.
3. Bad Why is the Earth's magnetic field collapsing? Because the iron core
of the planet has stopped rotating.
4. Bad:
The ship slams into a giant geode, and snags itself on a giant crystal of amethyst. The crew put on suits, go outside, and free the ship.

5. Bad:A microwave beam from space breaks through the weakened magnetic field
of the Earth!

Water Webquest
Create an informational blog about your action project and the impact on the watershed. Make it as a public service announcement. Include a picture.
Evaluation:
Your project will be evaluated based on the following criteria:
- Is your blog clear and concise?
- Does your public service announcement hook your readers?
- Does your public service announcement educate your readers to the problems of water pollution?
- Does your public service announcement inform your readers on what they can do to prevent or treat water pollution?
- Did you include a photo, creative commons or public domain only, with a powerful title?
The Task:
Th blog should help to increase public awareness about water pollution and it will hopefully help to prevent its spread or keep the water and climate clean.
In your blog, include the following information (what types of pollutions can affect OUR river?):
- What is water pollution (describe the 7 types)?
- What is a point source of pollution? What is a non-point source of pollution?
- What are some of the sources of water pollution (describe 3 causes, tie to your action project)?
- What are three of the consequences of water pollution?
- What can be done to improve the quality of water after it has become polluted? What are some actions that can be taken to help prevent water from becoming polluted?

Solar Energy
go to http://www.erpsk12.org/
go to greyhound spotlight. go to solar panel array.
How much energy was produced in March? How many trees saved? How many batteries?
How much energy was produced in April? How many trees saved? How many batteries?
Find today. How much energy today?
What do you think about our solar panels? How do you think kids should learn about them in school?
