An Easy Food Web Lesson

Posted by Mr. Oettinger on 15th October 2008

An Easy Food Web Lesson

Looking for a way to get your students out of their seats and up to the board for an interactive lesson?  Looking for a way to get students to rally around a lesson like fans at a sporting event?

Here’s a quick and easy way to introduce food webs to your class. 

  • You might first introduce this lesson in a constructivist manner with some socratic discussion.  Perhaps a question like “Where do organisms get their energy from; and where does the energy go?”
  • Print out and distribute enough of the aquatic food web cards so that each student gets one or two cards.  Announce to the class “I AM THE SUN” and draw a sun on the board.
  • Ask the students to look at their cards and to raise a hand if they have an organism that can use your sun energy.  Any student who volunteers a consumer at this point serves as a springboard to develop the discussion about who can use energy from the sun.
  • Have students with producer cards tape the cards to the board, or simply write the names of their organisms on the board and use arrows to show the movement of energy from the sun to the producer.
  • Continue with the next organisms that can consume the producers, working your way through the trophic levels.
  • Challenge students to draw the arrow to represent the movement of energy between organisms.  Inevitably, a student will draw the arrow in the wrong direction.  Other students will often notice and suggest the correction.  Otherwise, you may call attention to the issue and ask students to scrutinize the arrow for accuracy.  When this error does occur, make sure all of your students are paying attention when the correction is made.  The direction the arrows face is a huge aspect of this activity.  It can be difficult for some students to “get” the right direction for the arrow.  Spend the time it takes to make sure all students understand what the arrows represent.
  • Finally, ask students what the arrows represent, and ask what the diagram you just created is called.  Depending on the student responses, this may give you an opportunity to point out the difference between food chains and food webs.

Students tend to love this activity and it allows one to approach the topic from a constructivist perspective in which students work together to construct basic knowledge of this essential foundation to energy transfer and nutrient cycling.

The Power of Analogy: Teaching Biology with Relevant Classroom-Tested Activities

Posted by Mr. Oettinger on 5th October 2008

The Power of Analogy: Teaching Biology with Relevant Classroom-Tested Activities
Marcella W. Hackney and James H. Wandersee (2002)

Teaching Biology with Relevant Classroom-Tested Activities.I stumbled upon this book and it has been quite fortuitous that I obtained a copy of this publication — it is fantastic.

The book begins with a discussion of the basics of analogy, simile, and metaphor to help the teacher understand how bridging figurative language and meaning can have a valuable place in constructivist education.  The rest of the book presents chapters of sample activities using analogy, simile, and metaphor to teach typical biology concepts.

Each chapter has a detailed description of the activity, implementation guidelines, notes, specific example lesson blackline masters which have everything clearly listed (purpose, materials, guide to action), and generic activity blackline masters so you have an outline to follow for creation of your own lesson based on the example activity type.  Also provided are sample responses to the example blackline masters.

This book is as complete as it gets in terms of conveying a unique pedagogical technique, and provides enough scaffolding to aid the teacher in implementation of sample and generic lesson activities.  You’ll be up-and-running with a new activity for your classroom in no time.

Published by the National Association of Biology Teachers (NABT), you can’t go wrong with this quality book.

Cell Division as a Model for Exponential Growth.

Posted by Mr. Oettinger on 13th September 2008

Looking for an interesting way to introduce exponential growth early in your ecology unit?  Here’s a technology-based lesson in which your students can use computers, the internet, and spreadsheet/graphing software to construct this knowledge for themselves.

What you’ll need:

  • computer access (suggested one computer for each pair of students).
  • internet access to www.cellsalive.com.
  • about 45 minutes of class time (one period).
  • graph paper; OR optional spreadsheet software for graphing.

What to do:

Go to the CELLS alive! bacteria cell cam page.  First instruct students how to use the cell cam, and make sure you already have practiced it yourself.  Below the three cell cam frames are buttons you can use to step forward in time by 1, 5, or 20 minute intervals.  This will change the center intermediate frame only.  Or, you can enter a frame number below the frame and click out of the text box to see the frame change.

Start at frame number 1 on the intermediate frame and step forward in time by one or five minute intervals.  You will see the bacteria cells divide.  It is not important to be precise about the exact minute/frame that the cells divide.  As the number of cells increases, it can be difficult to identify the exact frame in which division took place.  Look for an obvious cleavage furrow.  Students will realize after the first couple of cell divisions that the number of cells doubles with each division, eliminating the need to actually count all of the cells formed.  It is okay to estimate which frame the cell division happens.

Have students keep track of time at which each division is observed/estimated and the number of cells at each division.  After stepping through about four hours of cell divisions (takes only a couple of minutes), there will be enough data to graph.

A sample graph of the data will look like this:

Clearly we have exponential growth here.

Note that if if using spreadsheet/graphing software in this lesson, you can first teach your students how to make a simple spreadsheet, format cells for data, and use the chart wizard to graph the data.  A fantastic technology lesson to support your life science topic!

Biology Inquiries

Posted by Mr. Oettinger on 6th September 2008

Biology Inquiries: Standards-Based Labs, Assessments, and Discussion Lessons
by Martin Shields (2006)

Biology Inquiries.The title says it all–this book is the real deal, and is a must-have for any life sciences teacher.  Written by Marty Shields, a master teacher who I have had the pleasure of working with as my cooperating teacher during student teaching. 

From the back cover of the book:

Biology Inquiries contains lessons that:

  • Begin with mysteries, questions, and challenges
  • Emphasize evidence, explanations, and justifications
  • Focus on common biology misconceptions
  • Foster questioning, exploration, scientific skepticism, and reflection
  • Guide students to construct understanding for themselves
  • Bridge research-based theory with classroom realities

Do yourself a favor and buy this book today, then start working these ideas into your lesson plans ASAP!!!
