  1. Biology 1b Environment

  2. C/WHabitats6-Jun-14 Aims:- 4 know what a habitat is 5 describe features of habitats 6 explain how organisms are adapted to their habitats

  3. Starter – 5 minutes • Write down as many differences between the arctic and a desert as you can think of

  4. Copy notes – 5 mins • A habitat is the place where an animal or plant lives • Habitats have different environments e.g. temperature, or light intensity • The organisms that live in a habitat have features that help them cope with the environment – these are called adaptations

  5. Activity – 20 mins • Choose an animal that lives in the desert or the arctic • Make a list of the adaptations that help it to live there • Now read about the mole on p29 • Describe an imaginary animal that lives underground in the arctic • Draw your animal

  6. Activity – 20 mins • Complete worksheet C1, Q1 only

  7. Plenary – 5 minutes • What is a habitat? • What does adaptation mean? • The sea is a habitat. How would you describe the environment in the sea?

  8. Homework • Do a poster on a habitat of your choice

  9. Are You On Target Today? Aims:- 4 know what a habitat is 5 describe features of habitats 6 explain how organisms are adapted to their habitats

  10. C/WAdapting6-Jun-14 Aims:- 4 know what adaptation is 5 link adaptations to the environment 6 explain how behaviour is adapted

  11. Starter – 5 minutes • List ways in which a fish is adapted to live in the sea • Streamlined shape • Lightweight • Gills instead of lungs • Eyes on both sides of the head • etc.

  12. Copy notes – 5 mins • Organisms can be adapted to: • Cope with heat or cold, light or dark, wet or dry conditions • Hide from predators or find prey • Move, breathe or reproduce more easily in their environment • Organisms change their behaviour during the day because the environment changes

  13. Activity – 30 mins • Read page 30-31 • Answer the questions a,b,c,d • Answer the questions 1-4 in the purple box

  14. Plenary – 15 mins • Make a full-page labelled diagram showing a choice chamber experiment to find out if woodlice prefer light or dark conditions • Read your answer to Q4 you did earlier. What would you do to make sure your experiment gave the right results?

  15. Homework • Describe how your behaviour changes in a day – what environmental and other conditions affect you (sunlight, wind, rain, noise, hunger …)

  16. Are You On Target Today? Aims:- 4 know what adaptation is 5 link adaptations to the environment 6 explain how behaviour is adapted

  17. C/WChoice Chambers6-Jun-14 Aims:- 4 set-up a fair test, and record results 5 make a conclusion from your results 6 say how the conclusion is limited

  18. Practical – 30 mins • Prepare a choice chamber that has four sections: • Wet and light • Wet and dark • Dry and light • Dry and dark • Add several woodlice • Draw your set-up then record the number of woodlice in each section in a table

  19. Conclusion – 20 mins • Look at your results • What do they tell you about what woodlice prefer? “Woodlice prefer … conditions. I know this because …” • How sure are you that you are right? Are all of the woodlice in one place? Why not? • What could you do to improve your test?

  20. Plenary – 10 mins • Draw a bar chart showing your results

  21. Are You On Target Today? Aims:- 4 set-up a fair test, and record results 5 make a conclusion from your results 6 say how the conclusion is limited

  22. C/WYearly Changes6-Jun-14 Aims:- 4 know how environments change in a year 5 link adaptations to the environment 6 explain how behaviour is adapted

  23. Starter – 5 minutes • Which is the odd one out in each row? Eagle Cat Fox Woodlice Butterfly Slug

  24. Copy notes – 5 mins • Organisms change their behaviour during the year because the environment changes • It is cold in winter; some animals migrate or hibernate, others grow thicker fur, and some plants grow tubers (such as potatoes)

  25. Activity – 20 mins • Read page 32-33 • Answer the questions 1-3 in the purple box

  26. Plenary – 20 mins • Start sheet C3

  27. Homework • Finish sheet C3

  28. Are You On Target Today? Aims:- 4 know environments change in a year 5 link adaptations to the environment 6 explain how behaviour is adapted

  29. C/WBirds as Predators6-Jun-14 Aims:- 4 know how birds are adapted to feed 5 link adaptations to the food type

  30. Starter – OR – 5 minutes • A mouse is seen running across a field. • It must have seen a predator OR …

  31. Notes – 5 mins • Copy: Birds’ beaks are adapted to help eat a certain kind of food • Answer p34 question (a)

  32. Practical – 30 mins • We are going to time how long it takes to pick up seeds and transfer them to a dish • Make a table with the three seed sizes along the top and three ‘beak’ sizes down the side • In each square write down the time it takes to transfer a certain number of that seed using that beak • If you have time, repeat each measurement to check your results are reliable

  33. Plenary – 10 mins • Write a conclusion for your experiment “I found out that …” • Explain how your results (numbers) show what you found out “I know this because …”

  34. Are You On Target Today? Aims:- 4 know how birds are adapted to feed 5 link adaptations to the food type

  35. C/WFood Chains6-Jun-14 Aims:- 4 know how to draw a food chain 5 use correct names for parts of the chain 6 draw and describe food webs

  36. Starter – 10 minutes Sparrow Lettuce gets eaten by Slug gets eaten by

  37. Worksheet – 10 minutes • Complete worksheet Food Chains in your books

  38. Notes – 5 mins • A producer is the first thing in a food chain – it is a green plant • A primary consumer is an animal that eats a producer – it is a herbivore – it is prey to … • A secondary consumer is an animal that eats primary consumers – it is a carnivore – it is the primary consumer’s predator

  39. primary consumer, predator, secondary consumer, prey, carnivore, producer, green plant and herbivore Activity – 10 mins • Copy your drawing without the labels • Now add the following words in the right places:-

  40. Plenary – 10 mins • Begin sheet C6 • Finish Q1-3 for homework • Clever cloggs:- • Attempt Q4

  41. Are You On Target Today? Aims:- 4 know how to draw a food chain 5 use names for parts of the chain 6 draw and describe food webs

  42. C/WRevision6-Jun-14 Aim:- revise the topic for the test using three games

  43. Game 1 – Question Quiz • Split into teams of 3 (4’s/2’s not allowed) • Each person makes a simple question from Cells and from Environment so you have 6 questions altogether • When ready, swap with another team – you have 3 minutes to write answers • Mark each other – explain where they went wrong • Decide which team won and come for a ‘star’ – if you can’t agree, neither team gets a star

  44. Game 2 – Taboo • In the same teams, choose a keyword each from Cells or Environment e.g. tissue, or primary consumer • Write it on a card with three other ‘taboo’ words • Swap one team member to be the ‘observer’ • The observer makes sure there is no cheating • Describe the word without using the taboo words • You have 1 minute for each word • Get it right before time is up or you use a taboo word • Agree and come for stars

  45. Game 3 – Buddy • In a pair, make two cards that go together e.g. “cell wall” and “not found in animal cell” • Hand in the cards and collect one at random • Now find your buddy IN SILENCE – you can mime to each other or draw in the air though!

  46. Poster • Make a revision poster

  47. Homework • Revise for test
