Transcript

  • 1. Class Discussion • What type of environment did you see? • How about the climate/temperatures? • Can food be found easily? • Where the animals/plants dependant on each other? • What were some of the concerns faced for survival?
  • 2. Tropical Park Field Rivers Savannah Ocean Garden Coral Reefs Temperate Mangrove Desert Tundra Rainforest Ocean
  • 3. Different types of Habitats/Biomes • Where can you find these habitats? • Explain the difference between these habitats. – Types of animals – Climate / Temperature – Plants / Trees • What are some of the concerns faced for animal survival? • Which do you think will support the greatest diversity of living things? Why?
  • 4. • Online reflection for the different types of biomes: • (refer to questions on the previous slide) • http://missliyanascience.blogspot.com/ • For more info on the different habitats and biomes visit here: • http://www.mbgnet.net/
  • 5. • Temperature Abiotic • Air • Water (Physical) • Other living Biotic • Sunlight organisms • Soil (Living)
  • 6. • The measure of how hot or cold is the environment • Affects the – Activities of organism • Active? Less active? – Types of organisms living there • Warm-blooded? Cold-blooded? • Most organisms cannot survive under extreme temperature
  • 7. • Needed by all livings things – Oxygen  Respiration by both animals and plants – Carbon Dioxide  Plants to carry out photosynthesis • Amount of air varies from place to place – Mountains – less O2 and CO2 in the air, less organisms are suited for survival there • Quality of air differs in different environment – City area  pollution, affects living things
  • 8. • Sun is Earth’s main source of light • Plants need light energy to make food – Photosynthesis • Influences growth changes in plants – Flowering and germination • Amount of light influences type of plants found in a particular habitat • Light influences animals too – Nocturnal / Diurnal animals
  • 9. • All living things need water for survival & carry out life process: – Source of food  fish – Reproduction  frogs, lay eggs in water. • Amount of water in the environment influenced by: – Amt of rainfall – Presence of lakes, rivers & streams • Determines the type of organisms that can live there • Environments with a lot of rain can support a greater diversity of living things.
  • 10. • Soil consists of: – organic materials like: • dead and decaying organisms – Inorganic materials • Minerals, water and trapped air • Composition of soil affects the type of organisms that can live there: – Some plants and burrowing animals may find it unfavourable to live in soil that is: • very wet • has few air spaces.
  • 11. • Every organism plays a role in the ecosystem • Organisms interact in many ways: – Use one another as food (Food Chain) – For shelter – Seed dispersal
  • 12. • Temperature Abiotic • Air • Water (Physical) • Other living Biotic • Sunlight organisms • Soil (Living)
  • 13. • Online crossword puzzle • http://www.armoredpenguin.com/crosswo rd/Data/2009.04/1905/19055236.047.html • Find out more about camels (this is useful for our future lesson on adaptations) • http://animals.howstuffworks.com/mamm als/camel-go-without-water.htm
  • 14. Data logger Activity • Please listen to my instructions • WB Ch. 4, pg 1-6
  • 15. Instructions 1. There should be 8 groups. 2. 4-5 members per group 3. Collect • a Datalogger OR a Thermometer according to group’s allocation. 4. Take note of where your group is suppose to go.
  • 16. Data logger Thermometer
  • 17. Groupings Group Activity Location Type of activity no. 1 Measuring A Open field 2 temperature 3 Measuring the B Open field 4 amount light 5 Measuring C Shade 6 temperature 7 Measuring the D Shade 8 amount light
  • 18. Exercise should take 15 minutes. LET’S GO!
  • 19. Building our own freshwater habitat…
  • 20. To do! • Online reflection: www.missliyanascience.blogspot.com • Crossword puzzle • Read –Today’s slides on class science blog – Camels (link on blog) – Habitats and biomes (link on blog)
