Monday 9-22-14 • LO:Understand the different levels of organization in living systems • ET: • What is ecology?
Plan of the day • Living things wrap-up • Untamed Video – what do biologists do? • Cornel notes review • Start unit 2 – ecology
Characteristics of living things • In your group, Read the characteristics of living things summary (pages 18-19). Alternate readers for each characteristic. Read all the text inside each box!) • When done reading, discuss how the list you created for Friday’s activity compared to the one in the book • You have 10 minutes • If finished before other groups, start Writing on your notebook the characteristics of living things from the book (black bolded letters in each box) • Read pages 20-23 to yourself
Get a Chapter 3 graphic organizer paper from the front of the room, cut section 1 and glue in a new page in your notebook • Title this section on your table of contents: Chapter 3 Learning Targets
Plan of the day • Start unit 2 – ecology • Organization of living things poster
Ecology concepts diagram • Individual organism • Population • Communities • Habitats • Ecosystems • Biosphere • Biotic & abiotic factors
Levels of organization poster • Decide on an organism (can be imaginary) • Draw a diagram that includes the organism, a population, a community, an ecosystem, and the biosphere • On the side, list the producers in your ecosystem, the consumers, the biotic and abiotic factors affecting your system • Identify a food chain of at least four biotic factors in your diagram (you can draw arrows to connect them – from producers to consumers)
Wednesday 9-25-14 • LO: • How energy moves through an ecosystem • ET: • What is the difference between a Food chain and a food web?
Plan of the day • Notes on energy transfer through ecosystems
Exit ticket • Explain which is a better model to represent energy flow through an ecosystem, a food chain or a food web and why?
Wednesday 9-26-14 • LO: • Designing food webs from different ecosystems • ET: • What organisms in this food web would be most affected if the pallid-winged grasshopper disappears from this chaparral ecosystem?
Plan of the day • Food web capture
Food web capture – 40 participation points!! • Decide in your group who will be the reader, the spokesperson, the document controller and the manager for today’s activity • Your group will create and ‘capture’ on your handout four different websites • You will have 10 minutes at each station to arrange the organisms on cards, to connect them with the arrows (think energy flow for the correct direction of the arrow point!!), and to transfer the completed food web to your handout • I will come and check your food web before you transfer it to your handout (use green cup to signal completion) • EXTRA CREDIT: ON YOUR FOOD WEB CAPTURE, IDENTIFY DIFFERENT TROPHIC LEVELS (Producers, primary, secondary, tertiary consumers)
monday 9-29-14 • LO: • Designing food webs from different ecosystems • ET: • Draw (names is fine) a food chain from one of the food webs you captured on Friday with at least three trophic (food) levels
Plan of the day • Pop quiz on food webs and feeding interactions • Finish Food web capture
tuesday 9-30-14 • LO: • Ecological pyramids • ET:
Plan of the day • Correct quiz on food webs and feeding interactions • Ecological pyramids • Start Pyramid activity
Pyramids of Energy • Organisms expend much of the energy they acquire on life processes, such as respiration, movement, growth, and reproduction. • Most of the remaining energy is released into the environment as heat—a byproduct of these activities.
Pyramids of Energy • Pyramids of energy show the relative amount of energy available at each trophic level.
Pyramids of Energy • On average, about 10 percent of the energy available within one trophic level is transferred to the next trophic level. • The more levels that exist between a producer and a consumer, the smaller the percentage of the original energy from producers that is available to that consumer.
Of the light energy that reaches plants and other producers, only a tiny fraction—about 1 percent—is captured by photosynthesis. • Only 10 percent of the energy available at a trophic level is typically converted to new biomass in the next trophic level.
