Junior Solar Sprint and Hydrogen Fuel Cell Car Competitions
The National Renewable Energy Laboratory hosts the U.S. Department of Energy's Junior Solar Sprint/Hydrogen Fuel Cell (JSS/HFC) Car Competitions. Middle School teams from all over the Colorado Region participate in this fun, educational and exciting event. Teams work together building solar and/or hydrogen fuel cell cars with guidance from a parent or teacher coach to compete in race and design categories. A "Spirit Award" is also presented to the team recognized for good sportsmanship. Building
Healthy Start, Grow Smart
Healthy Start, Grow Smart provides parents of newborns information about checkups and shots, breastfeeding and bottle feeding, changing diapers, installing car seats, bathing, communicating, keeping a memory book, what's it like to be a newborn, and more.
This series was an initiative of Laura Bush as the First Lady of Texas and sponsored by the Texas Department of Health. President Bush and Mrs. Bush have asked that this series of booklets be revised and distributed by the U.S. Department of A
Helping Your Child Learn Science and Technology
This guide offers a dozen fun learning activities parents can use at home to help children (ages 3-10) learn about bubbles, bugs, surface tension, adhesives, friction (using gelatin), volume (using measuring cups), static electricity (using balloons), cause and effect (using plants), chemical reactions (using cake), and more.
Education Quiz
Think you know what is going on in schools across the country? NCES conducts surveys with schools, organizations and individuals all over the United States. After collecting the information we publish the results. Data collections are done by mail, phone, and via the Web. The questions below come from many NCES surveys. Read the questions, select your answer, and click on the "Evaluate Answers" button at the end to see your score! To start over, select the "Choose Again" button (at the end). The
Meals-Ready-To-Eat Scenario
You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemi
Introduction to Glycolysis
Living cells can process certain sugar molecules, rearranging their atoms and this process can supply energy to the cell to power growth and other functions. This process is called glycolysis. Glycolysis evolved billions of years ago when there was no oxygen in the earth's atmosphere and it was therefore impossible for cells to gain energy from the oxidation of sugar molecules using oxygen. Later when oxygen was produced as a byproduct of photosynthesis cells evolved to utilise oxygen to oxidise
Formation of Acetyl Co-enzyme A
This page explains the formation of Acetyl Co-enzyme A which is key to the synthesis of many organic molecules in cells. An acetyl group is a simple two-carbon-atom molecule which is sufficiently reactive to make it possible to use as a building block for larger carbon skeletons.
A large number of molecules that are synthesised in cells are built from two-carbon acetyl groups. An acetyl group derives from ethanoate (acetate) and is named acetyl when it forms a group within a larger molecule. I
Class Discussion About Playing Ayiti: The Cost of Life
Ayiti: The Cost of Life is a role-playing video game in which the player assumes the roles of family members living in rural Haiti. At the start of the game, the player chooses a primary goal for his/her family: achieve education, make money, stay healthy, or maintain happiness. During the course of the game, the player encounters unexpected events and must make decisions that contribute to or detract from achieving the chosen goal. After students have played the game they will need to reflect u

Introduction to Computer Science: Programming Abstractions
This course is the natural successor to Programming Methodology and covers such advanced programming topics as recursion, algorithmic analysis, and data abstraction using the C++ programming language, which is similar to both C and Java. If you've taken the Computer Science AP exam and done well (scored 4 or 5) or earned a good grade in a college course, Programming Abstractions may be an appropriate course for you to start with, but often Programming Abstractions (Accelerated) is a better choic
Physical Geography
Physical geography is the study of the earth's dynamic systems -- its air, water, weather climate, landforms, rocks, soils, plants, ecosystems and biomes -- and how humans interact with the earth's systems. Physical geography is the study of the world around you. Everyone, every day, interacts with the earth's dynamic systems. I challenge you to join me on an exploration of the complex, and exciting world in which you live! This is a freshman level college course in physical geography. It requir
Evolution: artificial selection and domestication
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants c
Helmholtz Coils
The EJS Helmholtz Coils Model shows a the magnetic field between two circular coils of wire. The default configuration, known as a Helmholtz coil, sets the separation distance D equal to the coil radius R. These values produce a nearly uniform magnetic field B between the coils.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy.
The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Unit 3 - Facilitation process for household food security
This unit is will illustrate the participatory facilitation processes to be used in the communities and households. The participatory methods and tools we have discussed in Unit 2 can be use in any of these processes according to a plan of action to keep the processes flowing and the people participating in the learning cycle to progress in their empowerment and mobilisation to take action themselves. The processes start with the community and then move over to the care groups and individual hou
Household Food Security: Module 3: Sustainable Natural Resource Use. Study Guide
In this module your main task is to plan and carry out a set of activities with selected households in the community to help them gain a good understanding of their current and possible future use of natural resources in their area. Why is this important? As people become informed and take actions to manage their use of resources responsibly to obtain food, they will be able to sustain themselves and their families, break the cycle of poverty and protect the environment at the same time. To prep
