Pictures of CCD(interactive on buildiing a CCD)

CCD Lab

Using the CCD Lab, answer the following.

1.  You want to put together a space telescope.  To start with, you decide you need to check out the metal surface of your CCD.   What surface(s) could you use to detect the following  types of light at 100% intensity (make a table as shown below)?

Surface Metal      x-rays      purple        blue     green   yellow     orange      red
sodium
zinc
platinum
copper
calcium

2.  Now, decide which metal you will use for the primary CCD telescope.   Now, check the wavelength range at various intensities  (10%, 20%, 40%, 80%, 100%) using the table below?    How effective will this telescope be for bright objects?   Dim objects?

Intensity                     10%                20%                  40%                  80%                100%

Wavelength range


3.  Take a look at the values of current for a 75% intensity light on a platinum surfaceand write the current into the table below..

Wavelength vs. Current

100nm       200nm       300nm       400nm        500nm         600nm           700nm



What does the data in #3 tell you about the effectiveness of a CCD for ALL wavelengths of lights?   How would an alloy try to deal with this value?



4.  If you were to construct a space telescope, would you have more than one telescope available on a platform?   Explain your reasoning.


Turn in this sheet INDIVIDUALLY at the end of the hour.9

9/28 Should We?

This is due on 2/23/2012.   The paper (or digital artifact) must be shared individually.   Because of the number of people gone to, well....everything, I have made Friday a workday.


The James Webb Telescope is slated to be deployed in 2018, but......budget cuts may get in the way.

Your ASSESSMENT for this unit is to find out this telescope, compare it to one specific telescope located in space, a specific reflecting or refracting telescope and a specific radio telescope. Your goal is to decide if we need this telescope or not, based on what we already have.

This chart will be worth 20 points.

You will develop an opinion paper that is 5-7 paragraphs and supported with details, including whether or not the James Webb telescope should be built, how this will affect Sun research, how this affect our knowledge of neutrinos, and what we can potentially discover. This essay will be worth 20 points and will be graded as follows:

Thesis statement: 3 points
Supporting details: up to 10 points
Defined conclusion: 4 points
Grammar and Mechanics: 3 points

9/26Discussion of Telescopes

Read this article about the Hubble

Why is going back in distance really going back in time?

Shared space for discussion of telescopes.  Each telescope should include a

a) picture of the telescope
b) year deployed
c) description of wavelengths/spectra study
d) what we have discovered

9/24 Labs and Homework

Lab Assignment:  Complete 4 of the 6 labs on sun dynamics found here.  These are due on Friday.


TELESCOPES
In simplest terms, a telescope is a light bucket. That means it collects some sort of electromagnetic data to share. Today, we are going to look at some of the important telescopes that have been used in astronomy. In each, I would like you to describe the wave range of the telescope, where it is located, and famous people and discoveries spawned by the telescope. After you are done, try to rank the value from 1 (low) TO 12 (highest).

• Mount Wilson
• Very Large Array
• SOHO
• Hubble
• Spitzer
• Chandra   
• COBE
• Galileo's telescope
• Newton's telescope
• GOES-West
• Horn Antenna (Bell Labs)
• __________  your choice

9/18-19 Unit 3 and the Sun

Group Whiteboard questions:

1. Scan through the first 12 slides.   Then, discuss the statement  "Why is sunlight responsible for life on earth?"   List what evidence you have that supports the statement.
2. Focus on the radius and mass of the Sun and compare it to our Earth and Jupiter.   
3. Finally, look at the differences in temperature between the core and the convection zone, and try to explain it to me using a meaningful analogy.  (Example:  the difference between a tornado and a breeze is like a semi of rice grains compared to a dozen).

Day 2
Go to the link below. Try looking at a spectra that is 350 degrees, 1000 degrees, and 6000 degrees. What amount of visible radiation is shown in each of those? Why do we have blackbody spectra for stars?

 Investigate screen and experiment with the situations.  Predict what will happen under the following situations:

What will happen when the voltage is increased?
 With the voltage at a given amount, what will happen when the heater percentage is reduced?
If conditions are set so that light is being produced in multiple molecule mode, what will happen in single atom mode? Check your predictions.

 Questions: 1. What condition(s) must be met in order for light to be produced by a discharge lamp?

 2. What event(s) occurs to actually produce the light we see?

 3. Does the spectrophotometer indicate unique spectrums for each gas?

 4. What types of electromagnetic radiation are produced?

 5. How could this phenomenon be used by astronomers?

9/14 Take Home test

1.  Create an artifact that uses a Web 2.0 structure to contrast the following:

• a rocky planet
• a gas planet
• a moon
• an asteroid, Oort cloud object (comet), or Kuiper belt object (plutoid)

Include a table that lists at least 10 variables and any new resources you have found.

2.  Imagine that you are traveling to an uninhabitable part of the solar system.   Describe the protective structures necessary to:

• travel there safely (you can invent up to five things that do not currently exist)
• participate in some form of extreme sport while you are there
• communicate with the Earth (for this, tell me the time lag that would exist)

3.  Use the orrery Solar Space Scope and draw a scaled drawing from the sun for the 8 planets.    To do this, consider 1 AU to be 3 centimeters.

Now, discuss how this would affect the SIZE of the planets, which are not to scale.   If you wish, you can check out 'Scaling the Solar System'  or Exploratorium

4.   Check out the discussion about Pluto as a planet in your notes.

Link 1 (great video, but just reading the transcript will tell you most of this)

New Horizons mission

Pluto is a planet
Pluto is not 

Based on these resources, describe what New Horizons will tell us, whether you think Pluto should or should not be a planet, and 4 arguments to support your view.

9/12-9/13 Jovian moons

Read pp. 162-162, 167-168, 185-186, p. 206, 210-12, 230


Galileo became a heliocentrist largely due to his observations about Jupiter's 4 biggest moons:  Io, Europa, Ganymede, and Callisto.  Using his telescope, he observed these moons and their patterns around the planet.  He marked the motion of the moons in terms of Jupiter Diameters as viewed through his telescope.

Set up a Open Office Calc table with the names of the 4 moons at the top and the dates on the left side.

Gather data for at least 30 days using the Jupiter moon position applet a

Create a x-y scatter graph for each moon.
