NOS lesson ideas

After story and observations but before in class discussion Reflection: 1 -2 page discussion about Wednesday’s class activities and how they relate to the above readings (Derry Prologue, Hazen and Trefil).

Basic Inheritance LG: Understand how and why try to use minimal vocabulary • “Explain the difference between meiosis and mitosis. (result, process, when and where it happens)” • “How can a person be a carrier of a disease that they themselves do not have? ” • “What are Stem cells? Where can they be found? ” • “What will happen to an embryo at the stage of having eight cells if one of its cells is removed? ”

What would happen if two sperm fertilized one egg? A. The resulting embryo would have 2 copies of every chromosome. B. The resulting embryo would have 3 copies of every chromosome. C. This is the process that creates fraternal twins D. A and B E. A and C

Models

Reflection on Scientific Models Consider scientific models and what they can be used for. You’ve studied the usefulness of four different models of earthquake recurrence for certain types of faults in class and scientists in the videos you watched in the “Buildings Kill People” assignment use simulations to model earthquake effects. Does a model describe/simulate exactly what will happen in nature? If it does not, is it still useful? How can that be? Please type up a 1 – 2 page response. A title page is unnecessary but please remember an intro, body and conclusion. The rubric below describes how I grade your reflections except the length of our Reflections does not require headings and subheadings.

Straw Instrument • Put the bigger straw over the end of your straw instrument. This makes a sort of straw trombone! 7

Generalizing Musical Instruments • What are three characteristics that the straw instrument needed to 1. make sound, 2. produce a variety of notes, and 3. be loud? • Can the important features be generalized for your instruments and other musical instruments like the guitar, for example?

Reflection - Generalizing vs. Categorizing In class this week we’ve been trying to generalize how musical instruments work and how sound is made. This is different from what is normally done in music classes where the focus is to categorize musical instruments according to type (strings, woodwinds, keyboards, etc…) Please compare this to what Hazen and Trefil say about biology on page 276 “This is but one example of what is probably the most important development in the history of biology – the shift in emphasis from studying organisms (like plants and animals) to studying the chemical basis shared by all living things. ”

Book Review Project • Read a biography of a scientist • Write a paper that describes which of the Derry pathways to discovery best fits your scientists’ pathway to discovery. • Details here
