Unit 1 The Nature of Science

As we begin this semester we will be focusing on the "how to's" of science. Initially we'll assemble a basic plan for doing science beginning from the very basic requirement which is "to observe." We have noted that scientists next would do the appropriate "research" to see what the community of scientists have done in regard to the question. The proper method to create a "hypothesis" is next on the list of to be discussed and then we'll move on to the proper method of "expermental design." We will put all of these techniques into practice latter in September when we begin our investigation into the "Power of Sunlight" as part of the Planting Sciences project.

Can you nake the parts of the seedling labeled in the picture on the left? That should be a cinch. Now, name the parts of the embryonic plant you observed in the bean seed you dissected in class that relate to each of these parts. Remember, using the sometimes confusing language that frequently pops up in biology is the best way to comprehend it. (terms you should now know - cotyledon, hypocotyl, radicle, epicotyl (hey, we didn't learn that - we stayed with the more recognizable "true leaf").

Classroom Critters

The Axolotl colony has lots of company in room 118

Returning stars in the menagerie include an elusive but gorgeous juvenile corn snake. She currently remains incarcerated but never gives up the quest for freedom. She has a litter mate who is not so interested in escaping. Another snake joined the group as the result of a trade (three golden axolotl juveniles). This is a very nice black snake. I also received a generous donation to the collection of two fully grown Leopard Geckos. The female bearded dragon is another lizard that gets a great deal of attention.

Guppies occupy two tanks and Madagasgar hissing roaches and Lobster roaches as well as various collections of pond organisms provide the starting point for many conversations about living organisms. I also discovered a batch of grain weevils living in the barley seeds in the closet so they were moved into a critter keeper for further observation.
