Physics Assignment 3 Task 2

Today we're going to be writing an article about Space for New Scientist. This is part of the second space assignment. Complete the following questions in an article format, like the ones in the shared area.

P10:

• You need to explain how telescopes are used to observe space. Explain where they can be found, and what they look at.
• You also need to mention some woprk that the Hubble telescope is doing.

M6, 7:

• You need to explain what Edwin Hubble discovered about the Universe.
• Outline two pieces of evidence (cosmic microwave background radiation and red shift) that support his theory. 
• Explain in detail how red shift occurs, also metioning the Doppler effect.  

D5:

• Describe the Big Bang theory.  
• Explain how Cosmic Microwave Background Radiation (CMBR) provides evidence for the Big Bang theory. Include the radiation mapping of the COBE satellite in your article. 
• Explain how Red Shift provides evidence for the Big Bang theory.
• Describe the Steady State theory of the origin of the Universe.
• Compare the Big Bang theory to the Steady State theory.

Remember, a magazine article should be interesting to read and should contain some photos and diagrams to help illustrate your points.

Space - Investigating the Universe

This half term we will be finishing the assignment tasks on space. There are two jobs for this morning:

• Firstly, make sure you have finished the poster assignment from before Easter. Check this on the spreadsheet on Mr. Cole's computer.
• Once you've got the poster done, complete the questions here which realte to the next assignment:

1. What are optical telescopes? What are two disadvantages associated with them?
2.  Who was Isaac Newton? What did he invent to help develop astronomy?
3. Who discovered that the Universe is expanding?
4. Use this link to find a galaxy. What is it called? What telescope did you use to see it?
5. While looking at your galaxy from question 4, change the type of telescope you use. What happens to the image?
6. Watch the video to explain what red shift is. How is it evidence for the big bang?
7. Who proposed the steady state theory? Is it accepted today or not?
8. What is the hubble telescope? Where is it and what is it used for?
9. Draw a diagram to explain how the hubble telescope uses mirrors to create images.
10. Extension - For the next assignment you will have to write a magazine article. Take a new Scientist from the front desk and find an article you like. What is good about it? What makes you want to read it? Is there anything you would change?
