The Environment

  1. 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. 2. Tropical Park Field Rivers Savannah Ocean Garden Coral Reefs Temperate Mangrove Desert Tundra Rainforest Ocean
  3. 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. 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. 5. • Temperature Abiotic • Air • Water (Physical) • Other living Biotic • Sunlight organisms • Soil (Living)
  6. 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. 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. 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. 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. 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. 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. 12. • Temperature Abiotic • Air • Water (Physical) • Other living Biotic • Sunlight organisms • Soil (Living)
  13. 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. 14. Data logger Activity • Please listen to my instructions • WB Ch. 4, pg 1-6
  15. 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. 16. Data logger Thermometer
  17. 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. 18. Exercise should take 15 minutes. LET’S GO!
  19. 19. Building our own freshwater habitat…
  20. 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)
