How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This unit explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.

Lighting Up: Analysis Of Yeast RAS Genes Using A Chemiluminescent Southern Blot Procedure
Genomic and plasmid-encoded RAS2 genes from Baker's and brewing yeast strains will be analyzed using a shortened Southern blot procedure employing chemiluminescence. Unique parts of this procedure are the gravity-driven "upside down" transfer and a rotisserie-like hybridization oven, which greatly facilitate shortening the transfer time to 45 minutes and the hybridization step to 60 minutes. Chemiluminescence obviates problems associated with radioisotopes without sacrificing sensitivity: the pl

How Much Heat Will It Hold?
Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property of thermal energy that engineers use in many applications.
Using Microbial Eukaryotes for Laboratory Instruction and Student Inquiry
Because of their ease of handling, relatively fast life cycles, modest space and equipment needs, and interesting biology, microbial eukaryotes are excellent organisms for laboratory instruction from the introductory to the advanced level. Information regarding the care, maintenance, manipulation, and basic observations of two specific microbial eukaryotes, the plasmodial slime mold Physarum and the ciliated protozoan Tetrahymena, are described. Exercises exploring growth, development, and behav

Stealth Learning: Acquiring Knowledge About Vascular Plant Structure While Using a Vegetative Key
Many students find it tedious to learn the terminology that is used to describe the vegetative structure of vascular plants. An effective method is to acquire these skills "accidentally", in the process of identifying unfamiliar plants. This exercise uses a vegetative key to woody plants within walking distance of the lab. Before the lab, plants are labeled with alphabetic tags. Students are given a brief introduction, and then they attempt to identify each labeled plant using the key. If their

Newton's Laws of Motion
This 4:20 minute long video shows the three main laws of motion developed by Sir Isaac Newton and is down with excellent graphics.
The first law of motion, inertia, is when an object will not move or else move in a straight line unless an unbalanced force is on it. The second law of motion is the force mass and acceleration; acceleration fo an object depends on the mass and magnitude of the force. (force=massxacceleration) The third law of motion is the law of action and reaction. In
Biography of Rosa Parks
This 4:40 minute long video is about the life of Rosa Parks. It provides some insights into her choices and the impact they have had on history and Civil Rights. There isn't much depth in the video, but it useful as a reminder to students about the importance of getting involved.
National Park Service-Mississippi National River and Recreation Area
The Mississippi National River and Recreation Area includes 72 miles of the Mississippi River stretching from the cities of Dayton and Ramsey, Minnesota to just downstream of Hastings, Minnesota. The diverse stretch of the river flowing through the park consists of numerous natural, historic, recreational and cultural resources of national significance. This is a great resource for teaching about US Geography and the importance of the Mississippi River. Content is appropriate for upper elementar

What Students Want: Teaching from a Student's Perspective
Teachers often make assumption about what motivates, excites or frustrates their students. But how do students themselves view teaching? This video is from college students, but has applications for other levels as well. This 1:37 video is best used as an example of what teachers might do to improve by asking students who have left their classroom for a few years what helped them the most. I have done this and it is most valuable.
