The ABC's of Nuclear Science is a brief introduction to Nuclear Science. We look at Antimatter, Beta rays, Cosmic connection and much more. Visit here and learn about radioactivity - alpha, beta and gamma decay. Find out the difference between fission and fusion. Learn about the structure of the atomic nucleus. Learn how elements on the earth were produced. Do you know that you are being bombarded constantly by nuclear radiation from the Cosmos? Discover if there are radioactive products found in a grocery store. Do you know if you have ever eaten radioactive food? Find out what materials are needed to shield us from alpha, beta, gamma, radiation. Discover what have we gained by its study.

Introduces the object that contains almost all of the mass in the universe, the atomic nucleus. Antimatter, beta rays, fission and fusion, the structure of the atomic nucleus, how elements on the earth were produced, how we use the nucleus in every day life, and the effects of radiation in the environment are among the topics. The site includes nearly a dozen experiments that can be done in chemistry and physics classes, along with A Teacher's Guide to the Nuclear Science and Technology Wall Chart.

Dynamic plasticity and fracture. Damage of structure subjected to implosive and impact loads.

Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.

This course provides an introduction to the physics and chemistry of the atmosphere, including experience with computer codes. It is intended for undergraduates and first year graduate students.

How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve.

Concepts of building technology and experimental methods. Projects vary yearly and have included design and test of strategies for daylighting, passive heating and cooling, and improved indoor air quality. Experimental methods focus on measurement and analysis of thermally driven and wind-driven airflows, lighting intensity and glare, heat flow and thermal storage, and load deformation of materials. Experiments are conducted at model and full scale and are often motivated by ongoing field work in developing countries.

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection, and radiation. Students then apply these concepts as they work in teams to solve two problems. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same thirty-minute time interval. Students design their solutions using only common, everyday materials. They record the water temperatures in their two soda cans every five minutes, and prepare line graphs in order to visually compare their results to the temperature of an unaltered control can of water.

Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.

For this activity, students will be given a set of materials: cardboard, a set of insulating materials (i.e. foam, newspaper, etc.), aluminum foil, and plexiglass. Students will then become engineers in building a solar oven from the given materials, keeping in mind that the oven should not only be able to collect as much of the sun's energy as possible but also to store it. Students will experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation. Upon completion they will test the effectiveness of their designs both qualitatively and quantitatively. Qualitatively, they will attempt to actually bake something in the ovens. Quantitatively, they will take periodic temperature measurements and plot a temperature versus time graph. Afterwards, students will think like engineers and discuss the solar oven's strengths and weaknesses when compared to a conventional oven.

Thermal backgrounds in space. Cosmological principle and its consequences: Newtonian cosmology and types of "universes"; survey of relativistic cosmology; horizons. Overview of evolution in cosmology; radiation and element synthesis; physical models of the "early stages." Formation of large-scale structure to variability of physical laws. First and last states. Some knowledge of relativity expected. 8.962 recommended though not required. This course provides an overview of astrophysical cosmology with emphasis on the Cosmic Microwave Background (CMB) radiation, galaxies and related phenomena at high redshift, and cosmic structure formation. Additional topics include cosmic inflation, nucleosynthesis and baryosynthesis, quasar (QSO) absorption lines, and gamma-ray bursts. Some background in general relativity is assumed.

By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.

The study of clouds (where they occur, their characteristics, etc) plays a key role in the understanding of climate change. This site discusses how the relative thickness and altitude of various cloud types result in their either reflecting solar radiation or transmitting and trapping it, thereby warming Earth's surface. It features text, a scientific illustration, and links to other relevant topics and datasets.

This tutorial introduces students to the concepts of electromagnetic waves, wavelength, and the electromagnetic spectrum. Diagrams and written descriptions explain how wavelength is measured and explore the traditional divisions of the spectrum: radio, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

From radio waves to gamma rays, this video segment from NASA introduces the seven categories of the electromagnetic spectrum and how each type of radiation is part of our everyday lives.
