Scope on the Skies: Urban Legends
Urban legends become widespread from people simply not asking “Are you sure?” or looking into the topic and learning more before making a decision. But urban legends are also a great way to teach students to become good questioners—skeptics if you will—whenever they hear or read about these kinds of claims. A recent urban legend is generating interest due in large part to statements made by doomsday predictors, news media, and—coming to a theater near you—a movie celebrating our demi

DNA, RNA , and protein
Have you ever wondered why you look like your mother while your brother looks like your grandfather? Consult life's gigantic book of information! This resource contains an illustrated interactive explanation of RNA, DNA, and proteins. This resource is appropriate for all users as it provides useful background information to enhance STEM teaching and learning for all. Copyright 2005 EDC
The University of Illinois at Urbana-Champaign -- From Alchemy to Chemistry: Five Hundred Years of R
The University of Illinois at Urbana-Champaign created this online exhibit to illustrate several of the major shifts in chemistry from alchemy to modern chemistry and how chemists changed the way in which they discussed their field. Curious students and educators can find descriptions of thirty-six chemistry books covering the years from 1500 to 1964. Historians will adore the images of pages from the old books and find source links for some of the books discussed.
University of Illinois Extension-Schools Online: Apples & More
This all-about-apples website was created by Schools Online at the University of Illinois Extension. For educators, the Apples & More website presents a collection of apple-related activities in the subject areas of math, art, social studies, literature, and science. In addition, the site contains information sections regarding apple nutrition, facts, varieties, recipes, and apple preservation. The site also offers annotated links for apple history, apple growing, selection and uses, and cider.
Hydrogen, Fuel Cells & Infrastructure Technologies Program
This informative Web site of the US Department of Energy has a tremendous amount of content related to the development of fuel cells. The main sections of the site provide a general introduction to the future hydrogen economy, including explanations of the importance of fuel cells, their potential for raising energy efficiency and reducing emissions, and current application areas. Safety issues are also addressed online and in a downloadable document titled Guidance for Safety Aspects of Propose
University of St. Louis: Lunar Meteorites
From the Department of Earth and Planetary Sciences at Washington University in St. Louis comes this very informational site about meteors. The opening page of the site would serve a novice meteorite researcher in her or his discovery about these rocks from outside of the earth -- including information on how meteorites are named, where they come from, why they are important, etc. The site explains the difference between meteorites and meteoroids. Also of note is the List of Lunar Meteorites whi
Some of the most fascinating natural phenomena in the world are waterfalls. Cascading over and through the geological remnants of the earth's history, the water of the world falls, creating the familiar sounds of gurgling, crashing water. This topic in depth takes you on a tour of a few great websites devoted to waterfalls around the world and the U.S.The World Waterfall Database (1) site, from Bryan Swan and Dean Goss -- waterfall aficionados -- contains all sorts of great information about wat
Students are introduced to the concept of an environment and the interactions within it through written and hands-on webbing activities. They also learn about environmental engineering careers and the roles of these engineers in our society.
How Do You Store All This Data?
This lesson allows students to start seeing the data structure they will use to store their images. Students will be introduced to two dimensional arrays and vector classes. Students will be guided to see that a vector class will be the most efficient way of storing the data for their images.
Ring around the Rosie
Students learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of comparative mythology to consider why spinning and weaving are common motifs in creation myths and folktales.
Forces, Forces Everywhere
Students are introduced to Newton’s laws of motion. They learn about forces associated with motion, gravitational acceleration, weight, normal force, static and kinetic friction, drag, and free-body diagrams. These concepts are reinforced with the associated activity, Dragged Racers, to analyze frictional forces as they use their mousetrap-powered model cars to relate displacement, velocity and acceleration with external forces acting upon them.
Ramp and Review
In this hands-on activity — rolling a ball down an incline and having it collide into a cup — the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.
Heredity Mix ’n Match
Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple’s offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the “couples” in
This informational piece, part of a series about the future of energy, describes the structure of the sun and the reactions taking place there. Students view a diagram of the four layers that make up the sun and review their characteristics. The energy of the sun results from fusion, which is described in a three-step process. The sun's role in the food chain explains the tremendous need for light and heat from the sun. Other information includes the age of the sun and an estimation of its lifes
Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Ready, Set, SCIENCE!: Putting Research to Work in K-8 Science Classrooms
What types of instructional experiences help K-8 students learn science with understanding? What do science educators teachers, teacher leaders, science specialists, professional development staff, curriculum designers, school administrators need to know to create and support such experiences? Ready, Set, Science! guides the way with an account of the groundbreaking and comprehensive synthesis of research into teaching and learning science in kindergarten through eighth grade. Based on the recen
The lemon battery challenge
In this activity, students will learn how a chemical reaction can produce electricity. Learners will create a wet-cell battery to determine how much power it takes to run an electric car.
Explore a few of the ways plants pollinate each other in this video segment from Sexual Encounters of a Floral Kind.
Male Weedy Seadragon Carrying Eggs on Abdomen
This very short video gives excellent real life, close up footage of a male Weedy Seadragon carrying eggs on his abdomen. Weedy seadragons are one of only two species of seadragons, the second is known as the leafy seadragon (Phycodurus eques) due to the greater number of leaf-like appendages along its body. Seadragons resemble the seahorses to which they are related, having a bony-plated body and elongated snout; their tails are not prehensile however. This is a great resource to help buil
