Due Today, have out to be stamped: history of C.R. watershed and S.C.R.! Read pages 86 to 96 complete the questions on page 96. The Spineless Ones: Group Poster project: read p. 86-100. Create poster for assigned section. Questions on pg 96 Riparian zones pg. 27 Video: Life On the Edge (p. 103) (if time…) Homework: Stream Bugs in King County, p. 101-102. SCR #38: none

    7. Your Job: Use “The Spineless Ones” on p.86 to create a Poster that explains your topic Use pictures and keywords to make your topic easy for people to understand.

    8. Group Topics BMIs (what are they?) BMIs as Indicators of Stream Health (pollution tolerance) Classifying Macroinvertebrates Basic BMI Morphology Aquatic Insect Life Cycle

    9. One person stay behind to TEACH Other group members move to the next table to learn about that section. After a 3 rotations, swap teachers Your job is to try to verify/correct answers questions on p. 96. You have until 10 minutes before the end of class to review posters/COMPLETE p. 96 This will be your exit task!

    10. P. 94 #1. What is a BMI? BMI = Benthic Macroinvertebrates Benthic = bottom dweller Macro = can be seen with the naked eye Invertebrate = no backbone

    11. #2. Why are they indicators? Why look at them? BMIs are sampled as a means of assessing both habitat and water quality. Population Fluctuations: varied life spans range from a few months to many years-this allows Biologists to evaluate the full effects of intermittent and continuous pollutants

    13. #3 How are they classified? All are found in the ANIMAL Kingdom (see page 86 in your booklet) Only three phyla: Annelids-segmented worms Mollusks-clams, snails, etc Arthropods-insects, crustaceans, etc.

    14. #4 Morphology For insects (p. 87) you look at the head, thorax and abdomen to identify species.

    15. #5 Life Cycle Two types: Complete and Incomplete Metamorphosis

    16. #6. Functional Feeding Groups

    17. River Book Assignments List: Completed & Stamped: Page 3 - Wrestling the Mississippi p. 10-17 - Daily Water Use, Activity 2&3 p. 24 key vocabulary p. 27 – Riparian Zones p. 35,40,41 - CR Watershed History Summary of a watershed. p. 84 – Interactive Watersheds Due Today: p.96 –The Spineless Ones & BMI posters Due Next Class (homework): Stream Bugs in King County p. 97-102
