Kinetic and Potential Energy of Motion
In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pend
In this activity, students will learn the meaning of preservation and conservation and identify themselves and others as preservationists or conservationists in relation to specific environmental issues. They will understand how an environmental point of view affects the approach to an engineering problem.
Power and the state
This is a module framework. It can be viewed online or downloaded as a zip file. As taught Autumn Semester 2010 The module compares and contrasts political decision-making structures in a variety of contexts, with the aim of analyzing questions of power within and across nation states. The module gives students an introduction to comparative politics – and so forms the basis for later and more detailed studies in the second and third years. It encompasses numerous examples to help students
Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.
Ike and Little Rock
This video segment, adapted from American Experience: "Ike", profiles the president's controversial response to the Little Rock school desegregation crisis in 1957.
"We Didn't Have Flies Until the White Man Came": A Yankton Sioux Remembers Life on the Plains in the
In the era before the U. S. Army conquered the Great Plains Indians the region's giant buffalo herds provided the primary food and clothing source for the Indians who lived there. Indeed, in 19th century America buffalo were more numerous than people. The various Lakota Sioux tribes who lived in the area that became South Dakota and Nebraska depended largely on the buffalo hunt according to Paul Picotte, a Yankton Sioux born in 1880. In this transcript of a 1968 interview with historian Joseph C
Some Clues to Describing and Understanding Organisms
This online guide helps students focus their biodiversity research in the classroom, field, and lab. It includes general and specific questions to consider, designed to help students see the clues they might otherwise miss and give them the vocabulary to discuss their findings. General questions include "What might this clue indicate?" and "Does the organism always occur in the same 'zone'? "Plant-specific questions range from "If it's woody, is there one main trunk (trees), or are there several
Life in the City
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a close-up look at biodiversity in a city park. The site opens by telling kids that, despite appearances, a great deal of biodiversity exists in cities. That from tiny mites to mighty trees, thousands of species thrive there. It then takes them to a slice of life from a thriving city park, where they are asked to find 10 hidden critters living alongside the trees, plant
Feed the Birds
This OLogy activity introduces kids to the concept of biodiversity by helping them discover the diversity of their local bird population. To begin, students create a simple bird feeder from a milk/juice carton or a plastic soda bottle. They then fill the feeder with black-oil sunflower seeds, popular with a range of birds. In addition, they are given a list of additional foods to experiment with, such as millet, raisins, and breakfast cereal. Students track the birds that visit their feeder in f
Make Your Own Biodiversity Stationery
These OLogy stationery files give kids a great way to personally address biodiversity. The letterheads, provided as downloadable PDFs, feature colorful looks at:extinct animals (Caribbean monk seal, Carolina parakeet, woolly mammoth, and Tasmanian wolf) a thriving desert habitat arthropods (argiope spider, luna moth, emperor scorpion, horseshoe crab, and milkweed bug)
The design of the Biodiversity Counts resource collection allows you to tailor a curriculum by choosing the combination of resources that meet your requirements, needs, and time constraints. Mix and match to form your own curriculum or try one of the suggested combinations below-they offer a choice between investigating plants, arthropods, or both, in full or abridged versions.
Bough Down to Trees
Students become familiar with the impact trees have in their lives and learn about some of the conservation issues that we face in the 21st century.
Alternatives to the animal report
This "Rethinking Reports" series of articles offers alternative research-based assignments on folktales, animal adaptations, and biodiversity.

You Be the Conservator
This web activity, recommended for grades 5 and up, is designed to teach both content and process. The content areas addressed in this activity are the science of conservation and the history of the Hispanic American tradition of making santos. Santos are painted woodcarvings of saints in the Catholic Church. Conservators use scientific tools and procedures such as xeroradiography and microscopy to analyze objects. The science behind these tools and procedures is explained in this web activity.
Home Water Use
This lesson provides an overview of water use in the industrialized world, including a discussion of the increasing need for conservation as populations grow and water supplies stay roughly constant.
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer uses a model to represent what happens when substances dissolve in water. The interviewer then asks for a prediction of what would happen when two clear solutions are mixed together. The interviewer uses the model to help the student build an understanding of what happened to form the precipitate.

In-depth interviews with children that uncover their ideas about the topic at hand.,This segment provides an example of a student explaining evaporation.
Students across the United States and Canada send symbolic butterflies to Mexico each fall. At the monarch sanctuaries in Mexico children protect the butterflies all winter and send them north in the spring. United by the monarch butterfly, children across North America learn lessons of conservation and ambassadorship.
