Needing Illumination: Investigating Light
This is the first lesson of this unit to introduce light. Lessons 1-5 focus on sound, while 6-9 focus on light. In this lesson, students learn the five words that describe how light interacts with objects: "transparent," "translucent," "opaque," "reflection" and "refraction."
10.4 Summary
In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.
1.6 Imperialism Related to the idea of transferring regulation across borders, is the influence of colonial tradition and of trade relations. The European colonisers, notably the UK and France, transferred their accounting rules to their colonies, so that Singapore, for example, had the same rules as Cyprus and Nigeria (Walton, 1986), while Cameroon shared rules with Lebanon, Vietnam and Guadeloupe, amongst others. Modern academic notions of ‘imperialism’ include the idea of economic dominatio
A Simple Solution for the Circus
In this activity, students are challenged to design a contraption using simple machines to move a circus elephant into a rail car. After students consider their audience and constraints, they work in groups to brainstorm ideas and select one concept to communicate to the class.

USC Dentistry: International Periodontal & Implant Symposium 2011 (Stanford Pt. 2)
Clark M. Stanford presented a lecture titled "Surgical Implant Placement -- Immediate Loading vs. Staged Loading in the Esthetic Zone" as part of the 36th annual USC Periodontal and Implant Symposium held in Los Angeles in 2011.
Stanford is the Centennial Fund Professor at the Department of Prosthodontics and Dows Institute for Dental Research, and associate dean of research at the University of Iowa. He also maintains a clinical prosthodontic practice within the College of Dentistry. His resea
Bats
Information about the myths/misconceptions that commonly abound concerning bats which is useful for developing an appreciation of this misunderstood mammal.
Imagine The Universe! - X-ray Astronomy Puts Einstein to the Test
Readers can learn about the latest advancements in X-ray astronomy, and how the newest generation of instruments are making observations of the behavior of light, matter, and space-time in the vicinity of black holes. These observations are then compared to results predicted by Einstein's General Theory of Relativity. Links to a glossary are embedded in the text of the article.
Planting Bulbs
Children are encouraged to plant bulbs and then observe the growth of roots and leaves. Includes a diary for recording the bulbs' growth.
Basic Chemistry: Some Laws and Definitions
Useful glossary with a list of definitions for basic chemistry terms and laws.
Great Zoom into New York, NY: Central Park
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl

Frog tadpole
A tadpole is what hatches out of the egg that was laid by the adult frog. It lives in water and swims using its tail. It has gills and breathes underwater.
Sleeping Beauty Invades Rat's Genome
Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website (http://pga.mcw.edu) and the strains themselves accessible via a
Grapefruits
Baking soda can be used as an indicator of how much acid food contains. You can test grapefruit and orange juice, and you should find that grapefruits and oranges tested with baking soda produce some gas, but less gas when compared to testing lemon and lime juice.
