Break the Science Barrier - Richard Dawkins - Part 1 of 3
Break the Science Barrier follows the Oxford Biologist Richard Dawkins as he meets with people who have experienced the wonders of science first-hand. We meet the astronomer who first discovered pulsars, the geneticist who invented DNA fingerprinting, a scientist who discovered a protein that causes cancer, and others. Dawkins interviews famous admirers of science such as Douglas Adams and David Attenborough, and asks them why science means so much to them. We also see how dangerous ignorance of

General Classification of Igneous Rocks
These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The general chemical classification covers silica content (silica saturation), aluminum saturation, and alkaline and subalkaline rocks. This resource is part of the Teaching Petrology collection. http://

Who's Eating Who?
Developed for second grade. First the teacher will explain the 5 trophic levels of a food chain to the students using the hand out with the sample food chain (Figure 1). Then once they have learned about trophic levels, autotrophs, and heterotrophs, each student can begin looking through the magazines and cutting out pictures of animals to create their own food chain. Once each student has completed his or her food chain, you can have them share them with the group. Biology In Elementary School
Caille the Caterpillar
Developed for second grade. The purpose of this activity is to bring the food pyramid to life. Hang the caterpillar up in a place that is visible to all students and pass out the hand out. Break the class into six groups and assign each group a food category. Ask them to go through the magazines and find foods that fall in their assigned category and cut out the pictures. After about 10 minutes call the class back together. Each child is to pick one of the pictures that they choose to share with
Portrait of Edmund Boynton

Pomona College student Ethel Smith (class of 1906) sits on a lawn wearing a wool skirt, jacket, and tam-o'-shanter.
Aimed at healthcare practitioners, this learning object describes why hand hygiene is so important in a healthcare setting, then uses video clips to demonstrate correct, and incorrect, hand washing techniques.
Kamchatka: Siberia's Forbidden Wilderness
These lessons are designed for earth science and biology students in middle and high school classrooms, though extension suggestions for older and younger students will allow you to adapt each lesson for younger and older audiences. The lessons are designed to complement the Living Edens: Kamchatka program; each lesson will indicate clips from the program that focus on the topic at hand, though the lessons function equally well as stand-alone content.
From Page to Stage
Musical theater book writers, lyricists, and composers have long looked to literature for their inspiration and subject material. In this lesson, students will compare and contrast literary works and the musicals they inspired. Utilizing video clips and Web sites, students will compare specific passages from original texts to moments in Broadway musicals on which they were based, and analyze similarities and differences between the two. As a culminating activity, students will try their hand at
Changes in microstructure of a shape memory alloy (bi-crystal of austenitic CuAlNi )
Changes in microstructure of a shape memory alloy being heat treated and also mechanically deformed. A bi-crystal of austenitic CuAlNi is cooled, causing transformation to the martensitic (2H orthorhombic) phase. The process is reversed in the second half of the video, as the specimen is heated again. The rate at which transformation occurs is controlled by heat flow effects. (The shear process itself tends to take place very rapidly.) The martensitic phase is internally twinned. This is very cl
Physics Games: Laser
Play a game and find out about a Nobel Prize awarded discovery or work! Has it ever occurred to you that every time you listen to a CD or point with a laser pointer, you are holding the discovery of a Nobel Prize Laureate in Physics in your hand?
Where Have We Been? Tracing Family through a Timeline of National History
This lesson plan introduces students to examples of how wars and technological developments have impacted the movement of people throughout United States and world history. Students will learn about the effects of political, technological, and geographical issues on the population of one North Carolina community. Listening to oral histories by North Carolinians, students will hear first hand accounts about the impact of wars and road building on Madison County. Using a timeline depicting events
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The segment shows the interviewer helping the student think about the gas formed after materials are mixed together and whether it is a different substance. The interviewer refers back to a model represented by unifix cubes to help the student realize there is a new substance in the gas form captured from the reaction. The interviewer has the student test this by smelling the gas.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment is helpful in showing teachers a useful technique to elicit students' ideas. The interviewer uses a refutation by stating a comment about what some scientists believe and asks the student to describe what she would say to them to refute their claim.
