1. DO NOW Date: 3/23 -Make a pile in the aisle with your old DO NOW sheet. -Make a separate pile with ‘last’ week’s homework if you haven’t turned it in. -Put this week’s homework away. What are three abiotic parts of an ecosystem?

2. ESSENTIAL QUESTION: How do ecosystems change over time? OBJECTIVES: -Identify Abiotic and Biotic Factors in an ecosystem -Discuss their importance -Observe how the succession plot has changed over time

3. Succession Plot -Go outside and examine succession plot from two weeks before -Make observations along with predictions for another week -Note any new growth on the plot along with comparisons to the undisturbed ground around it

4. Outside Expecatations -Voice Level 0 in the hallway -Voice Level of 1 or 2 outside while you examine the succession plot -Classes are very near the plot, so be mindful of your volume! Stay in one spot in close vicinity to the plot where you can see and draw Do not wander!

5. Succession Plot DrawingAbiotic/Biotic Factors Predictions: What will you observe a week from now? Week 1: Week 2: 1000 Year prediction: KEY: Primary Succession Secondary Succession

6. ENGAGE: Word Sort Sort the cards at your table into two groups: Living (BIOTIC) Non-living (ABIOTIC)

27. Start End Secondary Succession Climax Community Wind Secondary Succession Disturbance Secondary Succession Disturbance Secondary Succession Disturbance Secondary Succession Most life eradicated; some seeds may remain in soil Secondary Succession Pioneer species enter Secondary Succession Pioneer species begin to grow Secondary Succession Pioneer species + other species begin to grow Secondary Succession A new community of organisms is being established Secondary Succession New climax community is established

28. Bare rock is exposed due to some type of disturbance like a retreating glacier or volcanic eruption. No soil is present. Pioneer species, like lichens and mosses, establish themselves on the rock substrate. Pioneer species die and decay, providing soil and nutrients for other plant species like shrubs and small trees. Small and Large trees begin to grow, and the community reaches an equilibrium or balance. This results in a climax community. Primary Succession: The establishment of new community where none existed before.

29. Pioneer Species: Lichens Moss

31. Climax Community Stable, end stage of ecological succession in which organisms use resources efficiently and balance is maintained.

32. Secondary Succession: The reestablishment of community following disturbance. Organisms are driven away or killed by some type of disturbance, like a forest fire, leaving behind only the soil. Pioneer species, like grasses and weeds, begin to grow from the soil. Roots and seeds left over may also begin to grow again. Some pioneers species die and are replace or outcompeted by other species like shrubs and small trees. Small and Large trees begin to grow, and the community reaches an equilibrium or balance. This results in a climax community.

33. Habitat Vocabulary pg 49 Primary Succession- when an area regrows after a disturbance has removed all plants and SOIL Secondary Succession- when an area re-grows itself after a disturbance has removed all plants and the soil still remains Pioneer Species- the first species to start growing in an area Climax Community- when an area has grown into a stable community

34. Climax Community Stable, end stage of ecological succession in which organisms use resources efficiently and balance is maintained.
