Demonstration Page

Below are samples of pages found throughout the PLB108 web course.

Since large blocks of text are very difficult to read off a screen, we designed each page be smaller blocks of text interspersed with graphics and animations that relate to the accompanying text.

The animations require that several plugins (add-ons) as installed in your web browser. Click here to test your browser for the necessary plugins.

The animations contained on this page are the work of the PLB108 development team consisting of faculty and GAs from the Department of Plant Biology, and instructional designers and multimedia developers from the Arizona State University Information Technology Instruction Support Group.

Flower Parts - We begin to make use of the interactive capabilities of computer based instruction with this example of using layers to teach the different parts of a flower.
Flowers - page2

Biomes - In this example, the faculty wanted to create a link between different biomes and their physical location in the USA.
Ecology - page6

Meiosis - Step animations are used to convey the process of Meisosis. In this three step process, student view short animations with corresponding textual description. The student can replay any segment of the animation, or return to the beginning and go through the entire sequence.
Flowers - page5

Meiosis in Ovules - This is an instance of an animation that begins with an image that students have seen previously, and then it zooms into the ovule for the animation for this page.
Flowers - page6

Peppered Moth - In order to teach the concept of natural selections, and to demonstrate the impact of industrialization on the environment, this drag and drop animation was created:
Evolution - page3

Covalent bonds - The process of the formation of Hydrogen bonds and how the atomic nuclei are held together by the revolving electrons is explained in this animation.
Chemistry - page6.html

How an Enzyme Operates - The selective bonding of proteins to specific molecules is shown here:
Macromolecules - page10

Nucleic Acid - Translation
Macromolecules - page13

Stem Anatomy - Mini quiz
Roots - page13

Plant Cells/Ken Patrick Trail - Animation vs. Zoom:
Cells - page1 continued on Cells - page11

Video

Staged interviews - A faculty member dressed as Charles Darwin and was filmed in front of a blue screen. A black and white picture of Darwin's studio was imposed on the background and dusk and scratches were added to create the "old" film effect.

Live interviews - faculty members were interviewed in their labs and in the field Microscopic footage.

Video clips captured using high-powered microscopes.

Time-lapse footage - frames were captured at equal intervals over a period of days and stitched together as one contiguous clip.
