Today we will be looking at how plants and animals are adapted to survive in different conditions.  Answer the following questions in your books, using the links to help you:

1. What things do plants need to survive and reproduce successfully? 
2. How do animals take in energy from the environment? Think of one example of an animal being adapted to do this better:
3. Explain what 'heterotroph' means.
4. Watch this video, and give the main resource that the plants are competing for:
5. Outline the adaptations that antarctic fish have that help them survive. - What is an extremophile?
6. Name one extremophile organism and where it lives. 
7.  List three things that animals compete for:
8. Complete this activity and give the biological definition of a community.
9. What is competition between organisms? 
10. Do organisms like plants or animals always compete for the same resources? Explain why:
11. When does competition occur between organisms (what conditions need to happen?)?
12. When individuals are in competition, which ones are the most likely to survive? 
13. Try this game. What helps a population survive longer? 

E.M. spectrum

Today we're going to summarise the E.M. spectrum work we've been doing so we're ready for next term. Answer the following in your books:

1. What are fibre-optic cables? What are they made form and what energy do they transmit?
2. What dangers have been linked to mobile phones and the electromagnetic spectrum? What have scientistts found?
3. Use the diagram below to explain which visible colour has the longest wavelength:                              
4. What is the Doppler effect?
5. Use the video below to describe how sound and light are both influenced by the Doppler effect:


6. Who used evidence from other galaxies to come up with the Big Bang theory? Briefly describe what the theory states:
7. Use the information above to explain why some of the galaxies in this picture appear red. Why are some more red than others?                                                                     
8. If redshift is one piece of evidence for the big bang theory, what is the other main piece of evidence that supports the Big Bang theory?
9. Try this activity.
10. Extension - Read about the theories regarding a big crunch or big yawn (click on 'the big bang' in the index and then scroll down). Briefly describe what each one states.
