Computational thinking can be used to take a complex problem, understand what the problem is and develop possible solutions to solve or explain it. In these six Quest, students will learn about the four stages of computational thinking:...

[Free Registration/Login Required] Explore how decomposition reactions are used to inflate an airbag in a car crash.

The tutorial investigates how to calculate integrals using partial fraction decomposition. Practice problems and examples with solutions are included.

Students learn about the worm life cycle and decomposition of life by creating small-scale worm ecosystems. Research groups share scientific data with groups at other schools using web-based communication tools.

This activity book explores science and the environment through soda bottles and other recyclable materials. Sections include bottle basics, decomposition column, kimchee (fermentation), soil meditations, predator-prey column, TerrAqua...

Interactive goes down to the forest floor to explore decomposition in a multi-stage game of detritus, dead animals and rotting vegetation.

[Free Registration/Login Required] Students cover the five general types of chemical reactions: synthesis, decomposition, combustion, single-displacement, and double-displacement. The flipchart concludes covering the reactions as the...

Article discusses the research on body decomposition undertaken by University of Tennessee researcher William Bass (since retired) at the university's forensic research center, popularly known as the body farm.

Use this prime numbers calculator to find all prime factors of a given integer number up to 1 trillion. This calculator presents prime factors of a number, prime decomposition in exponential form, CSV (comma separated values) list of...

Outlines the steps for the movement of carbon along the carbon cycle through photosynthesis, food chains, being dissolved into the ocean, the decomposition of organisms, fossil fuel formation, industrial use of fossil fuels, carbon...

The fours stages of the carbon-oxygen cycle are described - photosynthesis, respiration, combustion, and decomposition.

Everybody knows that worms are good for the soil, but not everybody knows why. This lab shows you how to efficiently measure earthworms within units of soil to determine their affect on decomposition and reduction of surface residue.

A professional journal that specializes in rural economics and sociology. Examples of topics: "Decomposition of olive oil production growth into productivity and size effects," "Which strategies for the beef chain challengers after the...

In this comprehensive interactive tutorial the area of forensic science is explored. Learn how are human remains identified and what clues might investigators find that indicate a homicide rather than a natural or accidental death. Also...

Learners learn how to find a common denominator between two fractions and then add or subtract the fractions. Decomposition is used to identify patterns in fractions that are relatively easy to visualize, and apply these patterns to...

Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.

This unit is designed for advanced programming classes. It leads students through a study of human vision and computer programming simulation. Students apply their previous knowledge of arrays and looping structures to implement a new...

Students observe and investigate how a catalyst increases the rate of a chemical reaction while not becoming part of the products of the reaction.

This Nobel website on the life and scientific work of Robert A. Millikan includes a biography, images, and internet resources for further reading and research. Also included are the 1923 "Presentation Speech" which praised Millikan's...

This site provides an overview of the role of energy in chemical reactions.

This interactive resource adapted from the Museum of Paleontology at the University of California, Berkeley shows how a dinosaur can be buried under sediment after it dies, become a fossil, and then become exposed and discovered by...

A science experiment to observe how materials decompose over time, By recording the smell, appearance, and movement of materials over three weeks, students will be able to make conclusions about their decompositions. Students will also...

The guided inquiry activity enables students to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products...

This comprehensive site delves into the life history, ecology, adaptation to desert life, and beetles as agents of decomposition.
