Hello Teachers!! The purpose of this experience is to have students learn and reinforce the history of the scientists involved in the discovery of DNA. In addition, it is hoped that through completion of the assigned tasks, students will develop the understanding of using computer programs to enhance their work, rather than the use of the program being the focus of the experience. It is for this reason that students are asked to choose an appropriate program for the different tasks, as opposed to instructing them to use a specific one. In this section, I have included the programs that the students should consider if they are having trouble thinking of them on their own.
Task One; Cells are Us
This interactive site is a story-like walk through cell division and how humans are conceived. It is an excellent summary of cells, chromosomes, and cell reproduction, presented on a simple but informative level. Students are asked to draw diagrams of a cell, chromosomes inside of a cell, and a cell splitting. Additionally they are to describe each illustration, in words, under the drawing. It is recommended that they use AppleWorks Drawing or Painting, or Kidpix for this task.
Task Two; Dolan Learning Center
The Dolan Learning Center is located in Cold Spring Harbor, on Long Island. There is an interactive museum there where you can learn about all the different factors of DNA and how your life came to be. At this site, there is a link called "Timeline". Click on this destination and explore the timeline of scientists that were involved in all of the discoveries and developments concerning DNA. Students are to choose 4 different scientists ( 2 females, 2 males) and summarize their impact on the discovery of DNA. Then use this information on a timeline. Timeliner is the recommended program for this task. Additionally, Inspiration can also be used to take notes on each scientist.
Task Three; Children Resemble Their Parents
This task will involve reading and navigating through a slide show. Your mission here will be to answer some questions and to create a labeled diagram of a flower. You should first choose a program and set up a page for you to answer questions on, and draw an illustration. Click on the link below, entitled "Children Resemble Their Parents". After reading the opening introduction answer the following questions on the page you created.
*Who was Gregor Mendel?
*What was his discovery?
Next, click on the button at the bottom of the introduction page entitled"Animation". This is a slide show about Gregor Mendel and his work with flowers. Use the information from this presentation to create a diagram of a flower, on the page you set up. Include the stamen, pistil, petal, and leaves in your drawing. It is recommended that students use AppleWorks Drawing program, or Kidpix to complete this task.
Task Four; The American Museum of Natural History
This site, created by the museum, is dedicated to teaching participants about genetic history and discoveries. There are areas of this site that explore crime scenes, history, and how genes work. The particular link of this site that is to be visited in this project discusses how humans and other organisms share common genes.
Here, students are instructed to click on a link which directs them to the article" Our Genetic Identity; We Are All Alike". They must then use the information given after the first paragraph, to generate a graph illustrating the sharing of common genes with other organisms. It is suggested that students use AppleWorks Spreadsheet, Graphers, or Graph Master programs to create the graph.
