This animated video, created by Support Center for Microsystems Education (SCME), illustrates how DNA microarrays work in the context of nanofabrication. The animation and associated narration describe "how a DNA microarray identifies complementary DNA (cDNA) strands from a sample. On the substrate...

In this video, created by Support Center for Microsystems Education (SCME), viewers are introduced to the concept of DNA microarray fabrication. Specific topics include: non-contact printing process, photolithography process and maskless photolithography process. This is the third in a series of...

The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragment at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends. This...

Stanley Cohen and Herbert Boyer's historic experiment used techniques to cut and paste DNA to create the first custom-made organism containing recombined or 'recombinant' DNA. Cohen and Boyer inserted the recombinant DNA molecule they created into E. coli bacteria by means of a plasmid, thereby...

DNA transformation is a naturally occurring but rare event in which DNA can be transferred into bacteria. In 1970, Morton Mandel and Akiko Higa discovered a way to make E. coli more 'competent' for transforming foreign DNA. Their calcium chloride method is widely used today to obtain high-efficiency...

This website from the Minnesota department of natural resources provides information on the Garmin DNR application. The purpose of the application, its functionality and screenshots are included. The site also includes links which may be used to download the program.

This 1-page document, from the Advanced Technology Environmental and Energy Center (ATEEC), summarizes a learning activity that helps students studying the concepts of biotic/abiotic factors and biodiversity. In the activity, students collect samples from outdoor areas, interpret data, and discover...

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan for students learning about polymers. The exercise will investigate the use of the "three arrow numbering system" for recycling polymers. The lab covers classes of polymers, their uses and physical properties of...

This video segment, adapted from ATETV, explores Engineering Technology by providing an overview of what skills students will need to learn in order to succeed after graduation. This specific video takes a look at an adult non-traditional student returning to school, and how the community college...

This 5-page resource, made available by the STEM Guitar Project, is a guide for wiring electric bass guitars and drilling holes in electric bass guitar bodies. The guide describes where and how to drill jack holes, basic wiring, and information on bass guitar setup. A bass guitar wiring schematic is...
