Energy, Matter, and Organization: Food: Our Body’s Source of Energy

Leave a comment

Special thank you to Mr. Frank for helping guide my biology students through the day.  Students are expected to adhere to our new seating chart and use class time efficiently to complete the following work:

  1. Finish the Relating Nutrition & Chronic Disease worksheet packet from yesterday.  The packet should be turned in when completed.
  2. Complete the Google Classroom assignment Food: Our Body’s Source of Energy reading and Google Doc worksheet.
  3. Students who finish should ensure they have competed the previous Google Classroom assignment Why Can’t You Hold Your Breath Forever?
  4. The next assignment will be the Molecules Reading assignment already loaded in Google Classroom.

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: How Humans Obtain Energy – Initial Model

Leave a comment

Our work today is to organize student prior knowledge of how humans obtain energy into a model that can be revised over the course of the unit.  Recent learning from the Strength video and worksheet from Monday should be used to help students fill out the initial model worksheet.  The worksheet must be turned in at the end of class, so students should work efficiently to:

  1. Select one of the four scenarios from the video
  2. Review that scenario by watching that segment of the video (see Monday’s post for a link to the video)
  3. Draw and label the body systems involved (including the major organs of the body systems) on the worksheet
  4. Explain how the person in the scenario both gets and uses the energy and matter needed to survive in the scenario.
  5. Complete the three questions on the back of the worksheet, answering as completely as possible.
  6. Turn in the worksheet at the end of class for credit.

For a review of body systems, visit the website InnerBody.com and watch the Crash Course body systems videos to learn more about body systems relevant to the selected scenario.

Energy, Matter, and Organization: Human Strength Video

Leave a comment

To introduce our second unit, students watched the Discovery Channel video Human Body: Pushing the Limits – Strength and completed worksheet questions.  Note: The worksheet will be entered as an assignment in the grade book, so students should turn it in upon completion.

The entire video is available to watch online on the Daily Motion website.  For students having difficulty accessing the video using a Chromebook, here are segments of the video found on YouTube containing the majority of the important video content.

Energy, Matter, and Organization: Ocean Acidification – Day 1

Leave a comment

We kicked off the lesson with an entry task focused on why we use fossil fuel combustion (to produce energy).  Students were then asked to consider one unintended consequence of fossil fuel combustion (releasing carbon dioxide into the atmosphere).  We followed that discussion with a video about ocean acidification (below) before concluding the lesson with an experiment in which students re-created the conditions of ocean acidification by measuring the change in pH after exhaling through a straw placed in water for one minute.

Energy, Matter, and Organization: Combustion – Day 2

Leave a comment

We continued our study of combustion with a review of why burning candles lose mass.  We watched a video in which Mr. Anderson describes not only the process of combustion but also the concept of Conservation of Mass.  At the end of the video, he mentions how neat a candle burning in the space shuttle looks, so I also included a video of the recent FLEX2 experiment aboard the International Space Station.  After the lesson, students completed a quiz connecting the concepts of combustion, cellular respiration, and photosynthesis.
