How Does a DNA Microarray Work?
No full textIn this YouTube video, created by Southwest Center for Microsystems Education (SCME), viewers are introduced to the structure of DNA microarrays. Viewers will learn about the physical structure of an array, how it works by utilizing the DNA hybridization process, and how an array analysis is interpreted. This is the second in a series of presentations on DNA microarrays. Supporting materials can be downloaded from the SCME website
Cell Taxonomy: How are Organisms Grouped?
No full textThis activity, from Hagerstown Community College, lets students explore biological taxonomies by examining samples under a compound microscope. Slides of bateria, protists, fungi, animals, and plants are compared for those differences that allow for their groupings into kingdoms and domains. The lesson includes student instructions and a worksheet for recording and interpreting their observations
Viscosity of Household Fluids
No full textThis classroom module will help students understand the process of viscosity testing and the behaviors of fluids though experiments with household materials. The guide includes directions for two modules to be completed over two weeks of class time, including notes on the experiments and analysis of the experimental data for both weeks. Lesson background, lab safety, and reference information are also included, as well as reference data and evaluation questions for both the student and instructor. Students should have a basic background in materials science, including the concepts of viscosity and and rheological behavior.Â
Khan Academy: What is Coronary artery disease
No full textFor readers who would like a crash course in coronary artery disease, this site from the Khan Academy is a great option. Taught in 12- to 15-minute sections, with the precision and simplicity of Salman Khan, the videos cover topics in order of complexity. The lessons start with What is coronary artery disease?, explaining the way the heart works and the nature of plaques and plaque build up. From there, Kahn takes readers on a journey through risk factors, atherosclerosis, heart attacks, healing after a heart attack, and the complications that one might expect after a heart attack. Readers are welcome to continue their medical education, moving on to a study of the rest of the circulatory system
Using Gold Nanoparticles for Bacterial Detection
No full textThis lab, presented by the National Nanotechnology Infrastructure Network, teaches students about gold nanoparticles (GNPs). Students will "learn the potential disease detection uses of GNPs, conduct research on modifying GNPs to be specific to other molecules, and complete a simulation using GNP assay tests to detect a simulated meningitis outbreak." A Teacher's Preparatory Guide and Student Worksheet are provided that give detailed guidance for completing the lab. Â
Silicon Solar Cell Efficiency: Comparing Input Power to Output Power of a Silicon Photovoltaic Cell
No full textThis lab, presented by the National Nanotechnology Infrastructure Network, teaches students how to measure the efficiency of a solar cell. Students will compare the output power of a silicon PV cell with the input power of incandescent light bulbs illuminating the PV from a set distance. A Teacher's Preparatory Guide and Student Worksheet are provided that give detailed guidance for completing the lab
Electronics Kits - SparkFun
No full textThis site provides new ways to engage electronics students. Sparkfun Electronics started in 2003 with the development of the Arduino Microcontroller board and over the years has added numerous sensors and other components to its offerings. The resources were developed for tinkerers rather than education but they can be used in an electronics lab
An Introduction to DNA Microarrays
No full textIn this YouTube video, created by Southwest Center for Microsystems Education (SCME), viewers are introduced to the concept of DNA microarrays including what they are and how they are used today. DNA microarrays are used in a variety of fields including medicine, agriculture, and toxicology and have led to important discoveries in disease research. DNA microarrays look at our genes and examine whether or not certain genes are present, and help us to compare DNA from different people or species. A short review of genes is included to provide a greater prospective for the functionality of microarrays. This is the first in a series of presentations on DNA microarrays. Supporting materials can be downloaded from the SCME website
Seeing Nano: Using Scaning Electron Microscopy (SEM) to View Nano-Size Objects
No full textThis lab, presented by the National Nanotechnology Infrastructure Network, teaches students about Scanning Electron Microscopy (SEM). Nanoparticles are too small to be viewed with a light microscope so a SEM must be employed which "uses electrons to image the surface of a material." A Teacher's Preparatory Guide and Student Worksheet are provided that give detailed guidance for completing the lab
DNA Microarray Fabrication
No full textIn this YouTube video, created by Southwest 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 presentations on DNA microarrays. Supporting materials can be downloaded from the SCME website
