Paper Model of DNA - 2009-2010


If you are looking for the patterns and some pictures for the paper DNA model, please look at my April 8, 2007 posts! Starting with:


http://cavalierscience.blogspot.com/2007/04/how-to-make-paper-model-of-dna.html


http://cavalierscience.blogspot.com/2007/04/cut-out-pattern-for-making-paper-model_08.html


http://cavalierscience.blogspot.com/2007/04/cut-out-pattern-for-making-paper-model.html
They include the directions and templates for making the model.
 
Here are the pictures of the DNA model that was made by my students for the school year 2009-2010.  The sections of blue and gold DNA were the result of instruction by my student teachers from the University of Delaware and are the school's colors.

How Long Will It Take To Clean Up the Oil Spill in the Gulf of Mexico? - An Engineering Calculation

Click on each page to view the calculations.  Here is the summary, or conclusion that can be inferred from the calculations:
If the oil reservoir contains 2 billion gallons and the well leaks at a rate of 1 million gallons/day, it will take 2000 days (5.47 years) to empty the reservoir. If the rate of shoreline fouling is 100 cubic inches of tar and oil per square yard of beach per every 10 days, then it will take 26,260 days to clean the Gulf (71.9 years) if the only method of tar and oil removal is to clean the beach.  Read the details below:

Protein Synthesis - Graphic Organizer - Storyboarding

I use storyboarding to teach the processes of protein synthesis, photosynthesis, and cellular respiration. I introduce my students to the concept of storyboarding by showing them this American Film Institute video, which can be found on these two web sites:

http://www.youtube.com/watch?v=pWPjjoOFIu8
or
http://www.afi.com/education/screened/demo/screened_tables_student.aspx
However, the above links have now become unavailable.  I'm leaving them in there for reference.  But I found another website that has the video!!!  https://app.schooltube.com/video/d2525f42fd3809f3dabd/Storyboarding%20(AFI's%20Lights,%20Camera,%20Education!)
I did find a website with a video about storyboarding on this website, even though it is not nearly as good as the original, I does give students ideas about drawing out stories as pictures or cartoons.
http://uwsslec.libguides.com/c.php?g=187016&p=1236350




I introduce this lesson by telling students that the class will be playing the roles of the molecules involved in the process of protein synthesis.  Before we can play the roles, we need to familiarize ourselves with the story and the characters of the story.
Here we talk about the characters by using this handout (example key follows):

THE STORY OF PROTEIN SYNTHESIS
THE CHARACTERS


Next, we begin to visualize the characters in the story of protein synthesis by drawing cartoon pictures of them on a storyboard hand-out that can be obtained from this web site:
Here is an example:

Here are some examples of storyboards for the process of protein synthesis:

After composing the storyboards for the process of protein synthesis, students "act" out the process by participating in the Protein Synthesis and Words Activity, which was designed by Lynn Marie Wartski, that is on the Access for Excellence Web Site:  http://www.accessexcellence.org/AE/ATG/data/released/0247-LynnWartski/index.php    I created a playbill and I display it in the classroom, during the activity.  It illustrates the characters and describes the activity.
My previous posts have the storyboards for respiration, the Calvin cycle, and the light reactions of photosynthesis.

Here are some examples of books that utilize graphics to teach:

Also, Larry Gonick's cartoon guides are fun and informative:

Cancer and Henrietta Lacks - Lesson Plan Resources

For about six years, I have been teaching some lessons about cancer that are culminating lessons for a unit of study on genetics. Here are some teaching resources that I use:

I show students videos from an NIH CDROM and use the Understanding Cancer student worksheets from the following resource materials that can be ordered from NIH.
Cell Biology and Cancer
http://science.education.nih.gov/supplements/nih1/cancer/default.htm

Students are assigned nonfiction reading and answer questions that are designed so that students are reading for information. The first article is:
Henrietta's Dance by Rebecca Skloot

Reading Questions written by teacher, Christine M. Anderson, 3/31/2006, for Middletown High School.

I also came up with a shortened version of these reading questions that match up to some news articles because there were times I needed to be flexible with the time that I was spending on the lessons and also some students needed some shorter articles that were easier to read.

Also, I just finished reading a book, The Immortal Life of Henrietta Lacks, by Rebecca Skloot, which would be of interest to students and teachers. Her web site also has links to some videos, including a video of dividing HeLa cells. http://rebeccaskloot.com/
Update: Here is a link to an interview with Rebecca Skloot about her book that was aired on Book TV on 3/19/2010: http://www.c-spanvideo.org/program/292685-7
Random House has also made available discussion, reading, and study guides to go with the book, which are available for download at the bottom half of this link:
https://penguinrandomhousesecondaryeducation.com/book/?isbn=9781400052189

Update 08/31/2018.  The September 18 issue of The Science Teacher, NSTA magazine, Volume 86, Number 2, p. 15 has a description of Teaching Resources on Henrietta Lacks that are based on the book written by Rebecca Skloot,  They were compiled by Ohio biologist/educator Christopher Monsour.  Here is a link to the resources: http://goo.gl/xd3Rg9      or

Update:  Oprah Winfrey has announced that she is making a film about Henrietta Lacks!
http://www.huffingtonpost.com/entry/hbos-the-immortal-life-of-henrietta-lacks-gets-release-date_us_58a35e8be4b0ab2d2b19b5b2
The HBO presentation of “The Immortal Life of Henrietta Lacks,” based on the book by Rebecca Skloot, is slated to debut Saturday, April 22, at 8 p.m. EST.
     I have just watched the HBO presentation "The Immortal Life of Henrietta Lacks," starring Oprah Winfrey.  The video may be interesting to those who wish to view a drama about Henrietta Lacks, but the film is not a suitable one for use in the classroom.  This is rather disappointing because I was hoping to be able to have an up-to-date, documentary film that could supplement lessons on cancer.  The film focuses on the Lacks family and has some mature themes dealing with mental illness, inappropriate language for middle and high school, child abuse and a rape scene. African American studies courses in college could use this video as a supplement.  The film is also lengthy and for students, the dialogue might not hold their interest.  There is a family featurette at the end of the video.  It has some information, but I cannot recommend it as a classroom resource.  Mrs. A. 01/13/2018.

I have found some video resources that may be useful. The first four are about the immortal cells of Henrietta Lacks:
This video has a history of the use of stem cells. It was suggested by teacher, Sandra Porto, that this might be a good video for students to use to create a timeline, or as part of a web quest.

The following lesson was used as an assessment/summarizing activity for students, so that they could demonstrate what they had learned about cancer.
Use of Graphic Organizer Introduces Students to New Information in the Subject Area

Purpose Students will practice self-regulated learning by producing a tri-fold brochure that assists them in organizing new information that has been presented. This brochure will be a brochure that can inform and teach others about cancer.

Goals 1. By the end of the lesson, students will be able to find facts and organize reading material.
2. Students will demonstrate the skill of “reading for understanding and organizing information.”

Activity Pass out a sheet of plain, unlined paper (to be used for the brochure) to each student. Instruct and demonstrate to students how to fold the paper into three sections. Indicate where to put the information in the brochure: Front cover to be labeled Understanding Cancer. Inside front cover to be labeled What is Cancer?, in the middle section label should read, Causes of Cancer, inside right, Types of Cancer, and the remaining section, Treatments for Cancer. The back can be used for additional notes. Students can use the information in their binders, as well as the two reading packets: Henrietta’s Dance, and Sticking It to Cancer. Written information, such as facts and vocabulary should be written under each label in the brochure. There should be at least 10 facts for each section. Have the students write down the facts first and then, they may illustrate their brochure with available materials.

Chemistry of Materials Project - Biochemistry

Here is the latest version of the Chemistry of Materials Project, with emphasis on biological chemistry. Also, the following link provides a list of some helpful web sites for information about the project's topics. I also am providing the link to the previous Chemistry of Materials project description.
Chemistry of Materials – Coordinated Science II –Project

Assignment and Objective: Understanding atomic and molecular structure expands our knowledge of the nature of the material world and advances the technological sophistication of society. Each student will learn about the history and chemical make-up of a commonly used material, and present that information to the class. Students will also be responsible for learning about the topics that are presented by others.  A very helpful website, titled What's That Stuff,? for this project can be found here:  http://pubs.acs.org/cen/whatstuff/

Procedure:
Each student will be assigned a topic by lot (random drawing from a container). Each student in the class will have a different topic to research, which will be one of the following topics:

∙ Henna ∙ Chili peppers ∙ Chewing Gum ∙ Insect Repellent
∙ Honey ∙ Food Coloring ∙ Food Preservatives ∙ Self Tanners
∙ Citronella Oil ∙ Kava ∙ Artificial Sweeteners · Pectin
∙ Catnip ∙ Kitty Litter ∙ JELL-O® · Chitin
∙ Sunscreens ∙ Licorice · Tattoo Ink · Cholesterol
∙ Marshmallows · Sports Drinks · Margarine
∙ Ice Cream · Leather · MSG Flavor Enhancer
∙ Fluoride ∙ Aspirin ∙ Chocolate
∙ Hair Coloring ∙ Cheese Whiz ∙ Agar
∙ Lipstick · Amber · Cinnamon

This is an independent, at-home research project.

Each individual student will present their research information to the class by presenting an 11” by 17” Shutter Fold (foldable) display of their work, which is constructed according to the attached directions and as demonstrated by the teacher. Pictures of sample displays are on this web site: http://www.cavalierscience.blogspot.com/
The display is to include the following:
­­­­­­ 1. a history of the use and/or invention of the material.
2. diagrams/drawings of the chemical structures, or chemical formula of all the ingredients that make up the
material.
3. the health hazards and health benefits of the material.
4. a biography of the inventors of the material, or a description of a company that manufactures the
material.
5. a copy of a patent from http://patft1.uspto.gov/netahtml/PTO/search-bool.html or
http://www.google.com/patents where the name of the material, or the important chemical ingredient in
the material has been put in as a search term.
6. a completed information sheet about the patent.
7. pictures of the material, or actual samples of the material.
8. The student’s research information should include a bibliography (MLA format), with a minimum of two
references. This is a formal presentation. The writing and project should reflect a student’s best effort.

During the presentations, the audience will take notes about each of the materials.
Everyone will be responsible for knowing the important facts about each material and will graded on their proper
participation as an audience.

The finished project is due on Tuesday, December 15, 2009. The Middletown Cavalier Chemical Science
Meeting will commence on December 15 and run through December 16 to allow for all students to have
an opportunity to present and gather the important information about each topic. Late projects will not
be accepted. Students must be prepared to present on December 15. Projects are a product grade for the
marking period and this project will be evaluated as follows:
∙ Visual Aid/Foldable presentation 20 points
∙ Important information included 18 points
∙ Well organized 06 points
∙ Pictures of Material & Chemical Structure 06 points
∙ Copy of Patent with Completed Information Sheet 20 points
∙ Bibliography – must have two sources 12 points
∙ Audience Notes 18 points

You can access the grading rubrics that I created at these links:
Making a Foldable Display - Chemistry of Materials Project
Oral Presentation Rubric: Chemistry of Materials Project Oral Presentation

Here is a previous list of topics that I used, when the curriculum had more emphasis on chemistry:
∙ Henna ∙ Chili peppers ∙ Chewing Gum

∙ Honey ∙ Polyurethane foam ∙ Food Coloring ∙ Food Preservatives
∙ Citronella Oil ∙ Kava ∙ Artificial Sweeteners ∙ MSG Flavor Enhancer ∙ Licorice

Dog Evolution - Case Study

Dear Case Study Teachers:

Our latest case study is “Not Necessarily on Purpose: Domestication and Speciation in the Canidae Family” by Thomas Horvath, Department of Biology, SUNY College at Oneonta.

In this clicker case, students learn about natural selection concepts and interpret phylogenies as they apply to the Canidae family. The case is based on the idea that the domestication of the dog was not likely an intentional event in human history. Rather, the dog as we know it was likely a result of natural selection events. Then, later intentional selective breeding events formed the many different breeds of dog. Most students are familiar with dogs and may be more open to the ideas of evolution and speciation when applied to this animal rather than to humans.

Evolution and Natural Selection Concept Map Worksheet

Change Through Time – Evolution by means of Natural Selection – Concept Map

This concept map can be used in at least three ways. First, you can use the map to preview what you will be reading in your unit of study; you can use it to look up information before you read. Or, you can use this concept map after you have read about the topic so that you can review the chapters that you have read. Third, you can use it as a study guide for a test.

For each topic that is circled, you should write down short descriptive phrases or words that are important facts about the topic. For example, on one of the lines attached to the Organizing and Classifying Life’s Diversity circle, you could write the words: binomial nomenclature (which refers to Linnaeus’s naming system that is still used today). By making short notes that are attached to each topic, you are “chunking” down the information and organizing it in a way that will make it easier to remember. Adding color to your concept map may also help you remember the information.

Unit Outline - Mastery Review - Transporting Chemicals Safely

I found this review that I had put together for Chapter 3 in Kendall/Hunt, Prime Science, Level 1. This might be an interesting way to talk about safety, in addition to going over laboratory safety rules. It's a different way of integrating basic chemistry knowledge with practical everyday application of chemistry to people's lives. All students have seen tanker trucks on the highways.

Mastery Review-Transporting Chemicals

1. What are chemicals?

Made up of matter
Atoms and Elements
Compounds

2. What is the importance of the chemical industry?

Important to manufacturing because it converts raw materials into chemicals that are used to make the products we buy.
Chemicals are made in large amounts (bulk chemicals).
Converts raw materials into products that are used directly, such as fuel.

3. How do you handle chemicals safely?

You need to be able to identify the chemical being transported and need access to information about the chemical.
Proper Labeling
Chemicals need to be properly packaged.
Chemicals need to be transported safely.
Teams of people need to be properly trained to dispose of hazardous materials.

4. What kind of information is on the chemical warning signs?

Hazard Classification (what kind of danger may arise)
Substance name and number code.

5. How to you identify chemical hazards?

Test for:
Flammability
Corrosion of metals
Is the chemical an acid or base?
What substances does the chemical react with?

6. How do you handle chemicals safely?

Know where to find out information about the chemicals.
Use the proper procedures for hazardous chemicals.
Know how to administer first aid.

7. What is the international code for chemistry?

A shorthand system for representing chemicals.
Elements are represented by international symbols.

8. How do we describe chemical reactions?

Word equations
Symbol equations
Balanced equations

9. Who are some important chemists?

John Dalton – said all matter is made of atoms
John Newlands – in 1863, he made the first periodic table by arranging the elements in the order of increasing masses of their atoms.
Dimitri Mendeleev – arranged the elements in the order of increasing masses and also according to similar properties (he put them in columns).

10. How is the modern periodic table used?

One can find the atomic number. (number of protons)
The vertical columns have chemicals with similar properties. (Groups)
One can find out the symbol and name of each element.
One can read a key to find out if an element is a metal, nonmetal, or gas
One can find out the atomic weight, which along with the atomic number, can indicate number of electrons, protons, and neutrons in an atom.

Genetics Project - Three Selected Case Studies in Genetics

The first case study is modified from the case study, The Death of Baby Pierre. I changed the name of the child to make it less likely for my students to search and copy the answers to the questions, from the answers online. So, if my students have decided to look at my blog, they have found the source of Case Study #1, and they can check their answers. For the Hardy-Weinberg equation, I re-wrote that section of the case study, as a guided approach to the answers, because my students have had minimal exposure to the application of quadratic equations. Some of my students still find the equation difficult to understand, but having a question that guides them through the equation, as least makes them somewhat aware that there is a way to apply genetic principles to populations, as well as individuals.
Herreid, Clyde Freeman, "The Death of Baby Pierre," National Center for Case Study Teaching in Science, 18 June 2008. University at Buffalo. <http://ublib.buffalo.edu/libraries/projects/cases/pierre.htm>.
Case Study #1 is about the genetic inheritance of tyrosinemia. Here is a video about a victim of this disorder. The first 5 minutes is informative and I can show that part to my students. The ending includes the family drama of the disorder.

Project Description
INTRODUCTORY ACTIVITY
CASE 1 – Recessive Inheritance


Student Name ________________________ Period _____
Due Date:

The genetics project consists of three directed case studies. For these case studies, you will complete an introductory activity, which is included with this packet. You will receive a “mark of completion” in the teacher’s grade book for having completed the introductory activity, and then you will receive the information that is required for analyzing the cases: The Death of Baby Jeanette, Huntington’s Disease – A Family History, and Hemophilia: The Royal Disease. For these cases, you will be drawing, organizing, and analyzing pedigrees, demonstrating your knowledge of Mendelian genetics, and answering structured questions that are designed to show, in your answers, your understanding of basic genetic principles. This also includes your knowledge of the DNA molecule and its role in inheritance. You will also be playing the role of decision maker as you analyze and state your findings about the cases. So, here we begin:
Case Study #2
This case study was adapted from the case study on this web site:
