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
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.
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
Development and Flooding: Is There a Connection?
In this lesson, students will take their knowledge about the hydrosphere and apply it to the issue of population growth and development. In particular, students will learn how increasing development in eastern North Carolina may have worsened the effects of flooding from Hurricane Floyd, due to lack of soil and tree absorption of run-off. Students will create their own development plans for North Carolina in small groups, explaining how their plan will benefit North Carolina’s water resources
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 â€˜ improvementâ€™ of livestock under domestication. They believed that studying domesticated animals and plants c
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
Medicine Games: Control of the Cell Cycle
Play a game and find out about a Nobel Prize awarded discovery or work! In this game you are to take on the job as a Cell Division Supervisor. Are you familiar with the different phases in the cell cycle? If not, maybe you should pay extra attention to the image of the cell cycle in the introduction.
Medicine Games: Incredible Megacell Game
Play a game and find out about a Nobel Prize awarded discovery or work! The compartments of the cell, the organelles, are so small that it was impossible to study their structure until the electron microscope became available in 1938. Albert Claude, Christian de Duve and George E. Palade were awarded ...
Who Has the Light?
This NOAA classroom activity explores bioluminescence. This PDF addresses: Which deep-sea organisms are capable of bioluminescence, and how does this ability benefit these organisms? In this activity, students will: compare and contrast chemiluminescence, bioluminescence, fluorescence, and phosphorescence, explain ways in which the ability to produce light may be useful to deep-sea organisms, and explain how scientists may be able to use light-producing processes in deep-sea organisms to observe
Using this lesson plan students will be more aware of how plants and animals adapt to wildland fire. They will: Discuss the adaptive strategies of plants and animals to survive fire. Observe plants and animals in your local area. Design a plant or animal that is adapted for fire survival.
Constitutional Issues: Separation of Powers
This lesson explores the important Constitutional mechanism providing for the separation of powers of government among three branches so that each branch checks the other two. Lesson plans use the New Deal to help teach this concept.
Teachers and Students Investigating Plants in Space
In this activity students will grow "AstroPlants," a special fast-growing plant used in Space Shuttle microgravity experiments.
