Closed universe
Which of the words on the left have you heard before?
In the back of your book, jot down where you’ve heard them
Think, Pair, Share
Champagne Supernova

2. Homework We will have finished this unit by the end of today’s lesson.
For next week, you will create a fabulous mind map covering the whole unit.
Remember to use as many visual prompts as possible
Write it in your planner!

3. Red shift, the big bang and the Fate of the Universe

4. Objectives To be able to model the big bang (analysis)
To be able to explain the evidence for the big bang (comprehension)
To be able to Compare the different fates of the universe, and explain difference (comprehension & analysis)

5. The Doppler effect
Red shift
Doppler effect & Redshift

6. Blue shift
Moving towards
Red shift
Moving away

7. This red shift of galaxies shows that they’re moving away from us,
Suggesting they all started at the same point
THE BIG BANG!!

8. Construct - The Big Bang
Modelling the big bang
Get a balloon.... And a pen
Add some galaxies

9. Cosmic background radiation
Other Evidence
Cosmic Microwave Background Radiation
Cosmic background radiation
is radiation left over
from an early stage
in the development
of the universe,

10. Apply to demonstrate
If the universe started from one point, and is continuing to expand outwards, what could the future possibilities be for the universe?

11. What are the possibilities for the future of the universe
What are the possibilities for the future of the universe? Write down your ideas
Think! – 30s
Pair! – 30s
Share!

12. The Fate of our universe
Depends on amount of matter
Open – keeps expanding forever
Critical/flat – stops expanding and stays as it is
Closed – Stops expanding, Starts Contracting
BIG CRUNCH!!

13. Summary
Sketch a diagram of the three possible fates of the universe ( )
Add onto the diagram
Big Bang
Big Crunch

14. A helpful example 
Yellow hat - I met one of my objectives because I know how to model the big bang using a balloon
Review
Choose a hat
Write a paragraph summarising the lesson in terms of that hat only
(e.g. if you pick black you can only say what was negative)
