Molecular Structure and Properties: Structural Formulas

Leave a comment

Special thanks to Mr. Frank for guiding students through the Lesson 29 PowerPoint.  The lesson follows up on learning from Lesson 28, with students working in the same groups of four to hypothesize how unknown compounds will smell based on the properties of compounds studied in the previous lesson.  Students are welcome to retrieve the Lesson 28 worksheet they turned in yesterday in order to complete the Lesson 29 worksheet.  Both should be turned in at the end of class.  For homework, students should complete Lesson 29 textbook questions #3-7.

Reminders:

  1. Use the wafting technique when sniffing the new compounds.
  2. We do not have access to butyric acid at school, but rest assured, it smells awful (putrid – literally like vomit).  Learn more about butyric acid at wisegeek.org.
  3. Please save the tubes for Ms. Schulze’s 4th period chemistry class.

Energy, Matter, and Organization: Relating Nutrition & Chronic Disease

Leave a comment

After the nice long Thanksgiving holiday weekend, we returned to our study of energy, matter, and organization by connecting our previous work deducing the formula of cellular respiration with the study of nutrition.  Students were tasked with completing the Relating Nutrition & Chronic Disease.  They were also encouraged to use the USDA’s National Nutrient Database to look up the nutrient content of any ingredients not listed in the worksheet packet.

Energy, Matter, and Organization: Organizing and Summarizing

Leave a comment

We used our time in class today to organize and summarize learning thus far on Unit 2.  Students have had several assignments and many needed some additional time to complete their work.  The goal by the end of class was to identify all of the work from the unit, summarize the key findings into a narrative, and store the work in student folders that will be kept in the classroom.  The folders will serve as a portfolio and as an organizational tool.  They will also allow students to easily present their work on the current unit during the Student-Led Conferences scheduled for this evening (from 2:30-6:00) and tomorrow (from 4:00-7:30).  Tomorrow we will share out as a class and come up with a common narrative to help students retain our learning over the long 5-day Thanksgiving weekend.

Energy, Matter, and Organization: Feedback

Leave a comment

We continued our learning from the Google Classroom by focusing on the last question in the worksheet that asked students to consider the effect of temperature on metabolism.  We watched the the “squirrel” segment (from 41:40 to 50:00 of the Can We Live Forever? video from NOVA scienceNOW).  Students then updated their answers to question 6 from yesterday’s worksheet.  The the last half of class, students worked in pairs to complete part 1 of the Keeping a Balance worksheet.  They reviewed homeostasis and negative feedback, applying their learning to the scenario of a car adjusting speed in an effort to maintain the set point speed (the speed limit speed of 55 mph).
