Both links above are webpages that simulate gravity of bodies in space. The first is pretty simple. Users can insert a disk of objects and add individual objects. Typically, the objects will merge to form a simple solar system. The second link (created by @astrodian) is a little more involved and allows for more manipulation by the user. Students can decide the number of stars and collide two galaxies together! How cool is that?!
There are MANY solar system/ Universe simulators out there in the web. The above link, Universe Sandbox is by far my favorite, and guess what? I just discovered that it is NOW FREE for schools! I’m super stoked! Universe Sandbox comes packed with pre-loaded scenarios, such as colliding galaxies, asteroid & space probe fly-bys, and even The Death Star orbiting Endor. That’s right. The below links are definitely cool and note worthy solar system simulators as well.
The University of Colorado at Boulder has an amazing site of fun, interactive, research-based simulations of physical phenomena. Not only does this site include awesome science and math simulations, but also each one includes teacher uploaded lesson plans, quizzes, and other resources to include with implementation of the sim. All simulations run on Java. Try out my personal favorite, Energy Skate Park! http://phet.colorado.edu/en/simulation/energy-skate-park
This page never ceases to amaze my students. I will often use it as a demo on my smart board, though I know they are dying to play with it on their own someday soon. This page features a sliding scale mechanism that zooms in and out, showing the relative size and distance between objects in the Universe, from quantum foam and strings to the edges of the observable Universe.
Okay, enough of the space sims! This page is extremely useful for any chemistry student of any age. Students can manipulate temperature to see the state of matter of each element, navigate properties, learn about orbitals and isotopes, and follow links to other pages the describe each element in more detail.
This page is simple yet fun. The webpage opens to a Hydrogen atom, showing the number of Protons, Neutons, Electrons, and the configuration of shells and orbitals. Students can simply click the NEXT or PREVIOUS button to discover the models of each element’s atom.
How could I leave out life science? This page has been around and improving over the past few years. Dr. Edward O. Wilson’s 2007 TED Prize speech was the catalyst for EOL, a database of all living things. New organisms are added daily. As a lover of nature and ecology, I can just get lost in this huge database of living things.
