Week 2 Biotic vs Abiotic Ecosystems & Ecosystem Interactions

Transcription

1 Week 2 Biotic vs Abiotic Ecosystems & Ecosystem Interactions Biotic vs. Abiotic Food webs, food chains, ecosystems, communities, populations, biodiversity

2 Monday Warm-up: Explain WHY the cats are living and the lego cat is NOT living. Give 3 reasons. Learning Target: I can explain the difference between biotic and abiotic factors of an ecosystem.

3 What s happening this week? Monday Abiotic versus Biotic factors in an ecosystem Tuesday SBAC in the morning with your PERIOD 1 teacher and periods 4-6 after lunch Wednesday Brain Games video (I will be here but not be HERE ) Thursday Parts of an Ecosystem Friday Food Chains!

4 Ecology 1. Look at the cards on your table 2. With your table partner, sort the cards (you BOTH get to decide how you want to sort them) 3. On your whiteboard record your rule for how you sorted the cards

5 Ecology Activity NOW re-sort the cards into: Living (BIOTIC) Non-living (ABIOTIC)

6 Ecology Vocabulary: You need 2 empty journal pages. Make a T-chart in your journal. Write these definitions. Below each word make an illustration that helps with the definition. (you will add 4 more words later) Word and Illustration Definition Abiotic Biotic Non-living chemical and physical factors in the environment Living things and the products of living things

7 Ecology vocabulary T-Chart: Word & Illustration Definition Non-living chemical and physical factors in the environment Living things and the products of living things

8 Abiotic ( A means not or without ) NOT alive - Abiotic factors can have a huge impact on an ecosystem - Discuss: What are some abiotic factors that are right outside our classroom? - Ex: water, wind, rocks, sunlight, etc.

9 Biotic ALIVE - All of the living, or once living, parts of an ecosystem - Discuss: what are some things that are biotic factors that are right outside our classroom? - Ex: students, grass, bugs, birds etc.

11 Flip to the next 2 empty pages of your journal: On the left page draw this. Ecosystem: a biological community of interacting organisms and their physical environment. Physical

12 In your journal, list all the ABIOTIC & BIOTIC factors in this ecosystem:

13 Abiotic & Biotic Factors w/s

14 Happy Tuesday! Warm Up: Is a wooden ruler biotic or abiotic? Why? Is a salad biotic or abiotic? Why? LT: I can identify abiotic and biotic factors in an environment. Biotic/abiotic factors w/s will correct Thursday

15 Crash-course video on ecology

16 Journal Entry: Ecosystem Stations Write down the station number and answer the following questions in your journal. 1. List 6 biotic factors shown in this ecosystem. 2. What ABIOTIC factors are part of this ecosystem? 3. What type of ecosystem would you say that this is? Use reference diagram on the whiteboard to help. 4. List 2 interactions that are taking place in this ecosystem (biotic-biotic OR biotic-abiotic).

17

18 CER: Is abiotic or biotic? In your journal, write a CER explaining why your chosen object below is abiotic or biotic. Remember to include THREE pieces of evidence and reasoning that ties in with EACH piece of evidence. Object options Table 1: Fire Table 2: Seaweed Table 3: A pinecone Table 4: A piece of gravel Table 5: A cell phone Table 6: A soccer ball Table 7: An earthworm Table 8: Sunlight

19 As a table group discuss your individual CERs and write 1 CER as a group on your whiteboard! Your CER should have the following: 1 sentence CLAIM 3 pieces of EVIDENCE you can directly observe 3 pieces of REASONING that explains how your evidence ties to your claim Be prepared to share with the class!

20 Wednesday Warm-up! Define abiotic and biotic. List 2 abiotic and 2 biotic factors in the room right now. We will grade the biotic and abiotic w/s tomorrow. Learning Target: I can describe how brain function changes with age and how the brain processes color.

21 Thursday Warm-up! Write down 2 things you learned from the Brain Games video yesterday. LT: I can define key vocabulary words related to an ecosystem. Please take out your biotic/abiotic factors w/s

22 Big Questions.discuss with your group and write notes on your whiteboard What is an ecosystem? What are the different parts of an ecosystem? Share out with the class.

23 Ecosystem card sort - Work with a partner - Sort cards into different piles: individuals, populations, communities, ecosystems, abiotic factors - Do your best! It doesn t have to be perfect!

24 Use this picture to resort your cards!

25 Ecology Card Sort Results! - As a class, make a chart on the board with the following columns: INDIVIDUAL, POPULATION, COMMUNITIES, ECOSYSTEM, ABIOTIC FACTORS - Each table group, pick 4 cards (of the 32 card) and write those 4 under the appropriate column - Record results in your individual chart - TAPE this worksheet into your journal

26 Add these to your Eco vocabulary T-Chart: Word & Illustration Definition Individual One single organism Population Community Ecosystem All of the individuals of one species in a specified area at one time All of the interacting populations in a specified area A system of interacting organisms and abiotic factors in a specified area

27 Ecology vocabulary T-Chart: Word & Illustration Definition One single organism All of the individuals of one species in a specified area at one time All of the interacting populations in a specified area A system of interacting organisms and abiotic factors in a specified area

29 Draw this in your journal. You can use different organisms than is shown below.

31 Ecosystem Parts ID W/S due tomorrow Desert Arctic

32 Ecosystem Parts ID WS River Jungle

33 Vocabulary Quiz next Tuesday! Warm Up: Give an example of an individual, population, community, and ecosystem in the picture. LT: I can build, and define key vocabulary of a food chain. No Friday reflection today! Please take out your ecosystem worksheet! (desert and arctic)

34

35 Big Questions: Discuss with your table partner. What factors help an ecosystem to succeed and survive? What factors cause an ecosystem to not survive? What is a food chain? Ecosystem Video (2 min)

36 Work with your group to create a definition for the following terms and write them on your whiteboard: Producer Consumer Decomposer

37 Food Chain

38 More Ecology Vocabulary! Flip to next 2 empty pages in your journal. On the left and right page make a T-Chart for definitions! Leave lots of space between each word. Underneath each word draw an example.

39 Word and Illustration Producer Consumer Decomposer Food Chain Definition An organism that makes its own energy (autotroph) An organism that eats another organism to get energy (heterotroph) An organism that breaks down another organism to get energy; recycle nutrients back into the ecosystem (phosphorus, nitrogen, carbon) A chain that shows how each living organism gets its food

40 Ecology vocabulary T-Chart: Word & Illustration Definition An organism that makes its own energy (autotroph) An organism that eats another organism to get energy (heterotroph) An organism that breaks down another organism to get energy A chain that shows how each living organism gets its food

42 Flip back to this diagram in your journal. Add in the 3 biotic factors to your diagram... Physical

43 Identify Producers, Consumers, and Decomposers in your ecosystem Work with your group to organize your ecosystem cards to show the relationships between organisms! What are some patterns you notice?

44 Discussion Questions: Talk through each question with your group 1. What are some patterns you notice within your ecosystem? 2. What would happen if one of your organisms went missing from your ecosystem? 3. Was this activity easy? Why or why not?
