1. Perceptions of Science Verity Ablett BTEC Extended Diploma in Applied Science

2. Lesson 1 The Nature of Science What is Science? In small groups, write 2 lists: 1. What can Science do? 2.What can’t Science do?

3. Science: A process by which we try to understand how the natural world works. Scientific Knowledge is what scientists draw from observations and data. There is no certainty in science, only degrees of probability (likelihood). Nothing is ever proven!

4. Science Knowledge Survey Fill in the survey, A = Agree B = Disagree

5. Astrology Do you know your star sign? Get into groups of 4. Read out the description of your star sign and decide if it matches with your personality.

6.  Aries (21 March-20 April)  Taurus (20 April-21 May)  Gemini (21 May-21 June)  Cancer (21 June-22 July)  Leo (22 July-22 August)  Virgo (22 August-22 September)  Libra (22 September-23 October)  Scorpio (23 October-22 November)  Sagittarius (22 November-22 December)  Capricorn (22 December-20 January)  Aquarius (20 January-19 February)  Pisces (19 February-21 March)

7. Astrology  Claims to be able to predict people’s personalities and life events based on the position of the stars / planets  Presented in a scientific way.  There is no scientific evidence to support it  There are more than 7billion people on the planet, meaning half a billion in each star sign  Any truths are correlation not causal.

8. Pseudo Science Something that is presented as science, but isn’t. Can be very believable and convincing. Can you think of any other examples?

15. Why should we trust / believe scientists? Question: ‘’Do you believe that climate change is real?’’ Why is this question flawed?

16. Belief is not relevant in science  Most scientists wouldn’t use the term ‘belief’ when talking about a scientific theory.  It is more a case of ‘accepting’ a theory based on the evidence.

17. Belief  Belief is linked to Faith  Which is linked to religion/spirituality  Scientists test Hypotheses by gathering evidence and using it to reach a conclusion.  This doesn’t mean science is ‘against’ or ‘anti’ faith, just that it is a separate thing.

19. Theories  Many people think that because scientists call them ‘Theories’ that it is just a guess or an idea.  It actually means that it is the accepted theory based upon the evidence.  http://www.youtube.com/watch?v=d80Lf 76Ht18 http://www.youtube.com/watch?v=d80Lf 76Ht18

20. ‘Rules’  There are certain rules (conventions) which need to be followed in order for a scientific theory to be accepted in the scientific community.  TED talk: Naomi Oreskes (Why should we trust Scientists?)

21. Lesson 2 – Scientific Questions

22. Scientific Questions:  Try to think of some questions that early scientists tried to answer.  Think about a time when very little was known about the world.  What were the first questions people attempted to answer?  Write one down then discuss with your partner to see how many you can think of.

23. Did you get these?  What’s up in the sky? (Sun, moon, planets)  What keeps us on the ground? (Gravity)  How does the body work? (Anatomy /Physiology)

24. Gravity  Aristotle, and Galileo made observations about motion.  Sir Isaac Newton

25. The Solar System  Early ideas about the Solar System included thinking the Earth was at the centre.  The ancient greeks were the first to study the stars and planets and come up with ideas.  There are still many, many unanswered questions about the universe…

26. Activity  Read ‘understanding the universe 1’  Make a timeline of early understanding  Now do the same for 2,3 &4.

28. Scientific Questions  Some questions have been answered by Scientists (to the highest degree of certainty anyway)  Some questions are currently trying to be answered by scientists  Some questions will never be answered using science.

31. Lesson 3 - Development of Scientific Theories Science is based on observations

32. Germ Theory  What are Germs?  How do we know they cause diseases?  For how long have we known that Germs cause disease?  Who was Ignaz Semmelweiss?  Who was Louis Pasteur?

33. 1. What are germs?  Brainstorm Germs (microbes)  Types,  Diseases they cause  Ways they are spread  Ways they can be killed

34. 2. How do we know germs cause disease? It seems obvious to us that germs cause disease, but we haven't always known this. What clues are there that germs cause disease?

35. 3. How long have we known?  How long do you think we’ve known that germs cause disease?

36. Who was Ignaz Semmelweiss?  Watch the video about Semmelweiss and how his ideas weren’t accepted for a long time:

37. Germ Theory  Read the factfiles on other scientists: Lister, Fleming, Pasteur, Jenner  Make a time line of understanding on Germ theory

46. Class Task  Make a list of all the things somebody who doesn’t believe Evolution might say.  You don’t have to agree with them, just think of all the reasons people may have for not accepting the theory of evolution.
