Wednesday June 6 – Monday June 18, 2018

We need empty 1/2 liter plastic water bottles please!

FOCUS QUESTION: What are the factors that led to the untimely death of Rhapsody and her unborn baby?  And what can we do to help the endangered SRKW population?

AGENDA: Students will begin their three final assessments:  Summary chart, Rhapsody model, and Water Filtration Engineering ChallengeThese will all be DUE by MONDAY JUNE 18.

  • For the summary chart (see link below), students will need to complete assignments and then write about: 1.) what they learned, 2.) how it connects to Rhapsody, and the 3.) NGSS standard addressed for each of the assignments.  This will be completed on the chromebook.
  • For the model, students will need to list information about the factors leading the Rhapsody’s death and make connections between them on paper model.
  • For the engineering challenge, students will design a filtration system, test it, make modifications to the system and test it again.  Students will then evaluate “competing” design models to determine the best design.

Final Model

Tuesday June 5, 2018

NGSS STANDARD MS-LS2-1.  Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. [Clarification Statement: Emphasis is on cause and effect relationships between resources and growth of individual organisms and the numbers of organisms in ecosystems during periods of abundant and scarce resources.]

Standard in “middle school friendly” language:img_4717.jpg

FOCUS QUESTION: If one organism’s population changes size dramatically, how will the other populations in the food chain be affected?

AGENDA: Students will brainstorm cause and effect relationships by completing population graphs for given scenarios.

  1. Warm-up: Sample “Sketch a Graph”
  2. Group “Sketch a Graph”
  3. Sample Scenarios

FOCUS QUESTION: Why can the Puget Sound only support the energy needs of 200 Orca whales but there are millions of herring?

AGENDA: Students will complete their energy flow models and share them with the class.  Next, we will process the energy needs of different organisms in the food web and why.  Finally, we will record our ideas on an Energy Pyramid Diagram.

This shows the 10% law – only 10% of the original stored chemical energy is passed on to the next consumer.

FOCUS QUESTION: What is a food chain and who are the “key players” involved?

AGENDA: Students will be introduced to Rhapsody, a pregnant SRKW that died just prior to giving birth.  Next, we will explore a Puget Sound Food Chain.

  1. Review SRKW Information (Slideshow)
  2. Rhapsody Video – What lead to the untimely death of Rhapsody and why isn’t the SRKW population recovering?
  3. Rhapsody Notes (see below)
  4. Puget Sound Food Chain Notes (see below)
