Cells & Homeostasis: PBL Research – Day 1

Today marked the beginning of our project team work investigating the problem of reducing the frequency of harmful algal blooms (HABs) in Puget Sound.  Students used their responses from the Seahurst Park pre-assessment worksheet from last Thursday to assemble into groups (questions 4 and 5).  Student groups then worked together to create a single shared Google Doc per group, with each student working in the group having their own Chromebook for simultaneous editing.  We concluded with groups creating a list of stakeholders and then selecting one to be the audience for their presentation.

At the start of class, I pointed out the HS-LS2-7 code written at the top of the pre-assessment.  Students learned about the Next Generation Science Standards and were also reminded of the Washington State high school credit requirements for upcoming graduation classes.

Matter, Atomic Structure, and Bonding: Nuclear Reactions

We continued our exploration of how the nucleus of an atom can change by launching into Lesson 15.  The lesson revolves around the Nuclear Quest board game where students learn how new elements are created.  Before launching into the game, students elected to review the Lesson 15 PowerPoint in order to better understand the key concepts and vocabulary from the textbook reading they were assigned over the weekend.  Students then had time to cut out the various game pieces (the board, the three sheets of nuclear quest cards, the two sheets of radiation cards) and look over the game instructions as preparation for playing the game and completing the Lesson 15 worksheet tomorrow.  For homework Tuesday, students should complete the Lesson 15 worksheet, Lesson 15 textbook questions (#4-12), and read Lesson 16 in the textbook.
