(2) Spreadsheets & Graphing
(3) Biological Databases
Activity a and b:
Three different data bases that I could use in teaching biology classes are:
Biodidac - this site would allow access to different line diagrams and digital images that would be useful in teaching both anatomy and biology. Example: Students could be asked to identify the parts of a plant and/or animal cell and create a color identifiation key for their diagrams. I would also have students describe the function of each of the parts.
Virtual Body - this site has great "virtual tours" of different body parts and even some organization games that would allow students to practice the arrangement and orientations of parts relative to one another. Example: Students could use this site as an introduction to human physiology standards material by having them research each of the systems and then identify how the systems work in concert to maintain homeostasis.
Virtual Fly Lab - this site allows students to be the researcher and conduct their own experiements with fruit flies without the mess. Students can be asked to keep a lab journal of their crosses and the outcomes of each cross. After some time, students could be asked to predict the outcomes of crosses as they begin to understand the dominant and recessive forms of each allele.
Using the virtual fly lab, some questions I could ask my students include:
1. Predict the possilbe outcomes of a cross of a wild-eye and sepia-eyed fly.
2. Are there multiple outcomes to this cross? Explain why or why not.
3. Determine if these flies could be homozygous or heterozygous.
(4) Chemical Databases
1. Using an interactive periodic table compared to a traditional periodic table allows the student to access more information in a timely and efficient manner as only so much information can be stored and read from a traditional paper table. Interactive tables allow the student to click to get information that is need.
2. Using an interactive periodic table allows students to easily view the characteristics which make the elements periodic. Different sites, such as Chemical Elements.com allow the table to be expressed by mass, electron configuration, number of neutrons, boiling point, melting point, etc.
3. Using an interactive periodic table is more likely to spark a student's interest in chemistry and how because it "talks" to them. They can explore information that is relevant and interesting to them therefore increasing the subject's usefulness to them.
Using an interactive periodic table, describe how the electron configuration of elements in the table changes as you move from the left side of the table to the right. What does this indicate about the reactivity of elements as we move from left to right in the table?

(10) Spreadsheet development
This is not a spreadsheet that is necessarily useful for my science classes but is a spreadsheet I use to track the athletes on the swim team. It is a useful resource for them, so I have included it here. My student athletes use it to track their standing on the entire team, within their squad, by recent best times, or their standing up to the last meet in league. I developed this spreadsheet so that I could easily sort my swimmers by best time so that I could create the line-ups for swim meets more efficently. I also use it to keep track of the times posted by other teams in the league so that I can anticipate the best places to swim my athletes at our League Prelims swim meet. It does not necessarily contain formulas but I do use it to add times to create an entry time for relays.
(11) GPS / Mapping
Tour de CSUN - kmz file
Plot of tour
Our total distance traveled was 1.12 miles.
GPS is a growing field of science that is being used by many industries including the military and insurance companies. It is a useful tool because it allows you to plot a desired path which would enable you to hit places of interest and to determine elevations and distances between objects or landmarks. This is important in the creation of maps and directions.
GPS could be used in my science classes as a lesson to help students to understand its uses in tracking organisms, such as the study of migratory patterns of many organisms or the home ranges of many endangered and threatened species so that humans can minimize their contact and impact on these creatures. To show this concept to students I would have them carry GPS sensors for a 24 hour period and record their locations every 30 minutes or hour. The information could then be used to determine their "territory" and their range. Classes could discuss how this would relate to tracking endangered species.
