1 21. Home Sweet Home 04/05/2017 EQ: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. Video Initial Thoughts: How do animals and plants get their food to survive?

2 20. Home Sweet Home 04/04/2017 By the end of Evidence I,I will be able to answer the following question: EQOD: Explain what does a food web model.

3 Evidence I: Do your chain hang with energy? Work with your partner to fill in the blanks in the food chain with the following abiotic and biotic factors: Grass, Cows, Humans, Sun, Earthworms Sun -> -> -> -> Earthworms Tell me your food chain, and if you re right you ll get 3 points!

4 Evidence I: Do your chain hang with energy? Work with your partner to fill in the blanks in the food chain with the following abiotic and biotic factors: Grass, Cows, Humans, Sun, Earthworms Sun -> Grass -> Cows -> Humans -> Earthworms

5 Evidence I: Do your chain hang with energy? So if cows give us energy with yummy burgers, and cows get their energy from eating grass, where is the source of this energy? Where does the chain START? Sun -> Grass -> Cows -> Humans -> Earthworms But when we eat, do we EAT rays of sunshine? Or do COWS eat rays of sunshine?

6 Evidence I: Do your chain hang with energy? So how are we able to get the energy of the sun into OUR bodies? Think about it

7 Evidence I: Do your chain hang with energy? Now, we re going to create a Food Web. A food web is made up of groups of food chains, modeling different interactions within an ecosystem. In your notebooks, use arrows to indicate how the following abiotic and biotic factors interact with one another. Grass Deer Sun Worms Mouse Bear Hawk, Fox.

8 Evidence I: Do your chain hang with energy? Now, we re going to create a Food Web. A food web is made up of groups of food chains creating different interactions within an ecosystem. Use arrows to indicate how the following abiotic and biotic factors interact with one another. Grass Deer Sun Worms Mouse Bear Hawk, Fox. Worms EAT EVERYTHING! Grass, Deer, Mouse, Bears, Foxes, hawks

9 Evidence I: Do your chain hang with energy? Food Chains and Food Webs are models of ecosystems. They represent different interactions between different organisms in an ecosystem.

10 Evidence I: Do your chain hang with energy? Think about it: In a normal day, who do you interact with? One person or many? How can you model (show) this as a picture?

11 Evidence I: Exit Ticket Please answer the following question in your exit ticket! Name and Date = +1, Evidence +1, Correct Answer = +1 and Sentence Frame = +1 USE YOUR NOTES! Question: Explain what does a food web model. A food web models the different between in an. According to Lesson 21, it says that (evidence)

12 Evidence II: Catch the (energy) flow :) By the end of Evidence II, I will be able to answer the following question: How does energy and matter flow within an ecosystem?

13 Evidence II: Catch the (energy) flow :) First, let s have play with some Play-Doh. Let s imagine the Play-Doh represents energy that s coming from the sun. One person in your table will begin by creating a shape with your Play-Doh :)

14 Evidence II: Catch the (energy) flow :) First, let s have play with some Play-Doh. Let s imagine the Play-Doh represents energy that s coming from the sun. Now, I want you to split it in half and pass it to your partner. Leave the original piece in front of you. We ll repeat this until it get really hard to split.

15 Evidence II: Catch the (energy) flow :) Let s think about it, what happened to the play-doh as it got smaller and smaller? Was there more to interact with or less? Now think about the shape of the Play-Doh, even though we changed its shape, did it ever STOP being Play-Doh?

16 Evidence II: Catch the (energy) flow :) Let s think about it, what happened to the play-doh as it got smaller and smaller? Was there more to interact with or less? Now think about the shape of the Play-Doh, even though we changed its shape, did it ever STOP being Play-Doh? Of course not! This is exactly how energy and matter work!

17 Evidence II: Catch the (energy) flow :) What we just did was model the cycle of matter and flow of energy within ecosystems. Matter is anything that takes up space. Like a book, water bottle, or you! Matter and Energy are neither created or destroyed. They just change shape! We saw this with the Play-Doh, as small as we made it, it still ended up being Play-Doh. It didn t just change out of nowhere!

18 Evidence II: Catch the (energy) flow :) Matter Cycles through the ecosystem as organisms interact with one another! Energy flows because some is lost as heat!

19 Evidence II: Catch the (energy) flow :) Now, let s talk about organisms. When looking at a food web/chain, what is usually at the very beginning and receives energy from the sun?

20 Evidence II: Catch the (energy) flow :) Now, let s talk about organisms. When looking at a food web/chain, what is usually at the very beginning and receives energy from the sun? Plants! Also known as Producers, these organisms change solar energy into chemical energy, which other organisms can consume as well. Example: Sunflower and certain bacteria. These organisms have a LOT of energy because they receive it from the source.

21 Evidence II: Catch the (energy) flow :) Which organisms consume producers, like grass and wheat?

22 Evidence II: Catch the (energy) flow :) Which organisms consume producers, like grass and wheat? Primary Consumers, usually herbivores, eat plants as their main source of energy. Examples: Sheep, rabbits, elephants. They carry less energy because they got it from the plants.

23 Evidence II: Catch the (energy) flow :) Which organisms consume primary consumers, like sheep or gazelle?

24 Evidence II: Catch the (energy) flow :) Which organisms consume primary consumers, like sheep or gazelle? Secondary Consumers, usually omnivores and carnivores, these are usually animals that eat other animals as their main source of energy. Also known as predators. They carry EVEN LESS energy because they got it from the plants.

25 Evidence II: Catch the (energy) flow :) And when these producers and consumers pass away, what eats them?

26 Evidence II: Catch the (energy) flow :) And when these producers and consumers pass away, what eats them? Decomposers, an organism that breaks down dead plants and animals into smaller forms of matter, recycling it back into the ecosystem. These organisms break down all others and recycle the energy to the Earth.

27 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer.

28 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Imagine I m the sun and I pass off my energy to the first organism, this organism changes my solar energy to chemical energy, what am I?

29 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Imagine I m the sun and I pass off my energy to the first organism, this organism changes my solar energy to chemical energy, what am I? Producer!

30 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Let s say I m some grass on a field and I get eaten by a gazelle. That gazelle is a..?

31 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Let s say I m some grass on a field and I get eaten by a gazelle. That gazelle is a..? Primary Consumer!

32 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Okay so that gazelle is galloping around and, suddenly, gets mauled by a Lion! That lion is a

33 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. Okay so that gazelle is galloping around and, suddenly, gets mauled by a Lion! That lion is a Secondary Consumer!

34 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. So that lion was named Mufasa and unfortunately his brother Scar decided that he wanted to be king and Mufasa was thrown into a stampede and passed away :( What s gonna eat Mufasa?

35 Evidence II: Catch the (energy) flow :) Let s model the cycle of matter and energy with Play-Doh again. Your job is to tell me if I m a Decomposer, Primary Consumer, Secondary Consumer or Producer. So that lion was named Mufasa and unfortunately his brother Scar decided that he wanted to be king and Mufasa was thrown into a stampede and passed away :( What s gonna eat Mufasa? Decomposers!

36 Evidence II: Catch the (energy) flow :) Exit Ticket Question: How does energy and matter flow within an ecosystem? Word Bank: Producers (x2), Decomposers, Chemical Energy, Lions, Secondary Consumers, Matter Answer:, like plants, use solar energy to create. Primary consumers eat, an example of primary consumers are gazelles. Afterwards, like,, eat primary consumers. In the end, all of these provide energy to, like mushrooms and bacteria, which help cycle energy and around the ecosystem.

37 Evidence III: Yass Model that Ecosystem Honey! Alrighty y all it s finally that time! We will get ready to model our Ecosystems! EQ: Collaborate with your team by creating a model of an ecosystem including its food web. Pero first, someone remind us, what is an ecosystem in the first place?

38 Evidence III: Yass Model that Ecosystem Honey! Alrighty y all it s finally that time! We will get ready to model our Ecosystems! Pero first, someone remind us, what is an ecosystem in the first place? An ecosystem is a biological community of interacting organisms and their physical environment.

39 Evidence III: Yass Model that Ecosystem Honey! Organisms, such as producers, consumers and decomposers all interact with their physical spaces. Think about it, how do you interact with your physical spaces at home? You sleep in your bed, you hang things on your wall, you use the faucet for water. It s the same thing! Animals use trees for shade or food, rivers to swim or drink and caves for shelter.

40 Evidence III: Yass Model that Ecosystem Honey! You have all been pre-assigned groups of 3-4 You will get to choose your own ecosystem, but no repeats allowed. We will choose in a random order

41 Evidence III: Yass Model that Ecosystem Honey! Tropical Rainforest Temperate Deciduous Forest

47 Evidence III: Yass Model that Ecosystem Honey! We will first get into our groups and you will decide who will take on each role 1. Project Lead, in charge of leading the group and meeting with Mr.Lerma, also timekeeper 2. Main Notekeeper, makes sure everyone has their notes and they are the main recorder 3. Researcher, main person in charge of the ipad and finding info. 4. If needed, Timekeeper Temperate Deciduous Forest Savanna Grassland Desert Coral Reef Wetland Taiga Ocean Freshwater Chaparral* Tundra

48 Evidence III: Yass Model that Ecosystem Honey! Assignment: Create a model of an ecosystem and its food web. PLAN: Write down your partner s name in your plan. Exchange contact info if you don t have it You will first plan the model with your group. Each of you MUST have a copy of the plan. This is what we should see: 1. 2 Different Producers, Primary Consumers and Secondary Consumers 2. 1 Decomposer 3. Landscape (Physical Environment, like Cactus, Trees, Water, rocks etc) 4. Materials Needed: Shoebox/Cardboard and you decide the rest. Bring from home please :) You will be provided with the following: Glue, Scissors, Construction Paper, Tape, and some cardboard.

49 Analysis 1. Trace the flow of energy, from producer to tertiary consumers, through an ecosystem you observed in the classroom. (Level 1) 2. Compare and Contrast your ecosystem with another group s ecosystem (Level 2) (use a Venn Diagram) 3. Predict what would happen if one organism in your ecosystem became extinct. How would it affect the ecosystem? (Level 3) Trace: To outline/show the steps

51 Summary, Big Idea and Vocab Take 7 minutes to work in a level 0 silence voice on your summary. EQOD: Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. Big Idea: Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. New Vocabulary Terms: Food Web, Producer, Primary Consumer, Secondary Consumer, Decomposer, Matter.
