This is where the thread was "born", but as of 7.30.22, this thread now has 157 pages full of links. Many/most listed in the first 20 pages are tried and true and I have taken some attempt to clump things together by subject. Past those more organized pages, you will find that the treads do tend to be material that I use and receive more information/links to what is offered. Let me suggest that you check out those first block of pages, then scan to look for your subject matter and grade levels without reading every post. You will get to recognize the links that most commonly pertain to your grades/subjects, so it is less to take in. I do have a tendency to bold entries that I find exceptional or well worth looking at, but that doesn't mean only the bold entries have merit. I have enjoyed sharing with other members, and will continue to do so. It would be fantastic if we could share a link that is highly beneficial/useful, that doesn't cost a thing to use, no hoops to jump through. I encourage others to add to my links, creating some nice references to have on-hand. You can never have too many resources. I love free when it comes to things that are handy to have, use, study, or simply enjoy. I started out looking for some inspiration for decorations for my classrooms, but found so much more. It seems like a waste to have it sitting in a file folder on my desktop, so I would like to share what I stumbled across in my browsing. Some are of limited interest to anyone not into science, but many have broader appeal and applications. Look at it this way - there is no charge for any of this stuff, so it is worth a peek! https://www.youtube.com/watch?v=fCLLJ6- 7ez0&list=PLexa_cotS5sHVVJzxb9A8BvnK8zYTH9IG Can't wait to use this in class http://www.opg.com/communities-and-partners/teachers-and-students/Pages/teachers-and-students.aspx http://www.nsf.gov/news/special_reports/science_nation/connect4learning.jsp http://learn.kidwind.org/teach https://student.societyforscience.org/science-project-resources http://www.familyscience.org/sample_activities.html http://ipadapps4teachers.blogspot.com/ http://www.msichicago.org/programs/summer-brain-games http://media.wfyi.org/IndianaExpeditions/ http://marstrek.jpl.nasa.gov/ http://www.birdsleuth.org/aabb-sound-lessons/ http://oceanexplorer.noaa.gov/explorations/15arctic-microbes/welcome.html http://www.nsf.gov/news/special_reports/darwin/ http://www.epa.gov/epawaste/index.htm http://www.futurity.org/ http://www.amnh.org/apps http://www.exploratorium.edu/neverlost/ http://theweatherwiz.com/ http://podcast.eol.org/podcast http://cosmictimes.gsfc.nasa.gov/ http://www.interactivedigs.com/ http://www.jpl.nasa.gov/edu/news/20...s-pluto-flyby-a-teachable-moment-for-students Get the FREE bulletin board!! http://www.energy.gov/sites/prod/files/2015/03/f20/beto_coloring_activity_book.pdf http://starchild.gsfc.nasa.gov/docs/StarChild/StarChild.html http://imagine.gsfc.nasa.gov/index.html http://www.energystar.gov/ia/partne...ivityBook-webPrint_041615_508v2.pdf?4203-3f87 https://takeactionscience.wordpress.com/ https://www.curiositymachine.org/challenges/ https://www.udemy.com/extreme-weather-101/ https://oceanclassrooms.com/moodle/course/view.php?id=8 https://scratch.mit.edu/ https://cset.stanford.edu/sites/default/files/INVESTIGATING ANT COLONY SEARCHING- A LINK TO A CITIZEN SCIENCE PROJECT.pdf http://www.carencooper.com/citscichat.html http://www.freetech4teachers.com/ http://www.seesouthernforests.org/ http://mathtrain.tv/ http://www.calculator-tab.com/ http://www.savemonkseals.ucsc.edu/ http://particleadventure.org/ http://tiktaalik.uchicago.edu/book-tools.html Goes well with "Your Inner Fish" http://www.webexhibits.org/ http://www.eia.gov/kids/ http://www.education.noaa.gov/coolsites.html http://www.fs.fed.us/outdoors/naturewatch/ http://www.astrosociety.org/pluto/ http://www.nasa.gov/mission_pages/station/main/index.html http://missionscience.nasa.gov/ http://www.exploringnature.org/db/subcat_index.php?dbID=45 http://www.scholastic.com/browse/collection.jsp?id=689 http://spie.org/x31474.xml?WT.svl=mdde11 This organization is the Elite of free posters for teachers.

I would give a shout out to HHMI.org, as they have a short FREE DVD on the genetics of pop-corn. I think I have everything, but they just keep adding new material, always free with free shipping to educators. You can also get the PDFs for their amazing posters to print. I have some back from when they were sent, and they are amazing. Found one I didn't have, and I had to have it printed out at a poster print place, but so worth it. Hopefully, and surely, others have more links to add to these. If these are in the wrong forum, perhaps a moderator will show it the home most suitable. If anyone is interested in some free jpg's ready to print as posters, a few inspirational, mostly science, PM me and I will send for free. I printed mine, the edits are done, and they are all suitable for 20x24 or larger. These include the HHMI posters I mentioned above, save the bees, Life's Family Tree, Mars Exploration Family Photo, the Curiosity rover, Charles Darwin quote, Mass Extinctions, Human Evolution, Earth Evolution and more. I will simply send as an email attachment? If I could figure out how to make these free downloads, I would be very happy to do that.
