Space Below, you will find a wide range of ideas and resources to help you when you are teaching children about Space. If you have any relevant resources to share, please email them and I will add them to this page. Thank you! 123D Circuits - Design and Test Electric Circuits Online 123D Circuits is a free tool from Autodesk for collaboratively designing electronic circuits online. On 123D Circuits you can design your circuits and test them on the simulator in your browser. You can create circuits from scratch or use and modify templates and other publicly shared projects. Autodesk recently published a short playlist of videos containing demonstrations of how to use 123D Circuits for various tasks. Short engineering lessons are included in the second half of the videos.

Place Value Blocks Game Guided Lessons are a sequence of interactive digital games, worksheets, and other activities that guide learners through different concepts and skills. They keep track of your progress and help you study smarter, step by step. Guided Lessons are digital games and exercises that keep track of your progress and help you study smarter, step by step. Moon Madness! I can't think of anything more fun to teach than space. The moon is one topic that I totally love teaching about! There's just so much great information out there. Nothing gets kids REALLY excited like learning about the moon! I have included some great videos, games and goodies (including a freebie) for you to use in your classroom as you study all about the moon! Cartesian Diver PC2 CON-2 — Supercharged Science OPT Rene Descartes (1596-1650) was a French scientist and mathematician who used this same experiment show people about buoyancy. By squeezing the bottle, the test tube (diver) sinks and when released, the test tube surfaces. You can add hooks, rocks, and more to your set up to make this into a buoyancy game! The test tube sinks because the when you squeeze the bottle, you increase the pressure of the water and this forces water up into the test tube, which then compresses the air inside the tube. When this happens, it adds enough mass to cause it to sink. Releasing the squeeze on the bottle means that you decrease the pressure and the water is forced back out of the tube.

Ocean salinity There are many chemicals1 in seawater that make it salty. Most of them get there from rivers carrying chemicals dissolved out of rock and soil. The main one is sodium chloride, often just called salt. Most seawater has about 35 g (7 teaspoons) of salt in every 1,000 g (about a litre2) of water. This doesn’t sound very much, but it would take three 6 m shipping containers full of salt to make an Olympic-size swimming pool as salty as the sea. Why salinity3 and temperature4 are measured Experience Just How Big the Universe is, in One Mind-Blowing Interactive You need a more recent version of Adobe Flash Player. Recently, NASA scientists combined data from the Spitzer and Hubble Space Telescopes to discover the most distant galaxy known to date. The galaxy, named Abell2744 Y1, was formed around 13.2 billion years ago when the universe was extremely young. As the universe is expanding, Abell2744 Y1 is currently closer to 40 billion light years away from us, an astounding distance.
