 | Thermal Energy Transfer - This interactive explains how heat is transfered by conduction, convection and radiation.  http://www.harcourtschool.com/activity/science_up_close/615/deploy/interface.html | ||
| Particles in Motion - This Java applet allows the user to change the temperature and pressure of a gas. Observe the changes in particle motion as you adjust temperature and pressure. The applet is near the bottom of the page. http://www.teachersdomain.org/asset/lsps07_int_heattransfer/ | ||
| Heat Transfer - Learn about convection, conduction and radiation in this interactive. http://www.wisc-online.com/objects/index_tj.asp?objID=SCE304 | ||
| States of Matter - "Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules." [site] http://phet.colorado.edu/simulations/sims.php?sim=States_of_Matter | ||
| Gas Properties Simulator - "Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other." (Site) http://phet.colorado.edu/simulations/sims.php?sim=Gas_Properties | ||
| Educapoles.org: The Different Types of Energy: Fossil, Atomic and Renewable - "The various sources of energy fall into three different categories: Fossil energies, which are produced from the combustion of natural reserves formed from organic deposits (plants or microscopic animal matter)over several millions of years. Nuclear or atomic energy, produced from the energy that binds... | ||
| Educapoles.org: Nuclear energy: when atoms explode - "Nuclear energy, which is also called atomic energy, is the form of energy that binds together the constituents of the nucleus of an atom. This energy can be released, mainly in the form of heat, with the disintegration of unstable nuclei (Uranium 235 or Plutonium 239, for example).Uranium is a radioactive... | ||
| Educapoles.org: Coal: Plant debris more than 200 million years old! - "There are three sources of fossil energy: coal, oil and gas. These are natural reserves that can be found buried beneath our feet. Formed from organic deposits (plants or microscopic animal matter), all of these sources of energy take several million years to form, and this under very specific conditions.... | ||
| Educapoles.org: Measuring energy: - "Sources of energy include water, sun and the wind, as well as certain matter, such as food, oil and uranium. Each of these sources is usually measured in different units (calories, litres, kilos, etc.)In 1849, it was established for certain for the first time that the total amount of energy remains... | ||
| Educapoles.org: Geothermal Energy - "Geothermal power involves harnessing heat contained in the ground. Deep below the surface of our planet, our Earth's heat comes mainly from the molten magma core. Close to the surface, part of the heat is also generated by radiation from the sun." [site]

| Educapoles.org: Natural Gas- Lightweight energy - "There are three sources of fossil energy: coal, oil and gas. These are natural reserves that can be found buried beneath our feet. Formed from organic deposits (plants or microscopic animal matter), all of these sources of energy take several million years to form, and this under very specific conditions.... | ||
| Educapoles.org: Oil: looking for black gold - "There are three sources of fossil energy: coal, oil and gas. These are natural reserves that can be found buried beneath our feet. Formed from organic deposits (plants or microscopic animal matter), all of these sources of energy take several million years to form, and this under very specific conditions.... | ||
| Educapoles.org: Biomass - Wood - "The biomass encompasses all living matter (plant life and animals). The three main sources of energy produced by the biomass are wood, biogas and bio-fuels: Wood is the oldest source of energy used by humans. Whilst it is little used in Europe these days, it remains the number one source of energy... | ||
| Educapoles.org: Biomass - The Biofuels - "The biomass encompasses all living matter (plant life and animals). The three main sources of energy produced by the biomass are wood, biogas and bio-fuels: Wood is the oldest source of energy used by humans. Whilst it is little used in Europe these days, it remains the number one source of energy... | ||
| The Temperature Game - Drag and drop items onto a thermometer - using celsius, fahreheit or kelvin scales, to compare values. Learn more about temperature as well. http://funphysics.jpl.nasa.gov/adventures/temperature-game.html | ||
| National Gegraphic: Global Warming Quiz - Test your knowledge and understanding of global warming. Take the quiz! http://environment.nationalgeographic.com/environment/global-warming/quiz-global-warming.html | ||
| PBS: On Fire - "Explore the basics of combustion, including how a fire ignites, how a molecule's atoms rearrange themselves during combustion, and what a flame is made of." [site introduction] http://www.pbs.org/wgbh/nova/cigarette/onfire.html | ||
| PBS: Rough Science - Make a Thermometer - On this site, explore what making a thermometer means, compare and contrast two thermometers and learn about temperature as you move your mouse over the interactive diagrams. http://www.pbs.org/weta/roughscience/series2/challenges/thermometer/ | ||
| Mystery Expansion - This interactive is an online mystery in which you attempt to identify the everyday substance that is the exception to the rule of expansion and contraction. Clues and hands-on activities are provided to help you solve this mystery. http://teams.lacoe.edu/documentation/classrooms/gary/heat/activities/mystery/Mystery.html | ||
