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/def...HING- 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" https://www.youtube.com/watch?v=17jymDn0W6U&feature=player_embedded 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 ordered all I wanted, they are exquisite, and come shipped rolled, not folded. Top Notch! http://nepis.epa.gov/Exe/ZyNET.exe/...ults page&MaximumPages=1&ZyEntry=1&SeekPage=x Gorgeous poster, free, but wish it had come rolled . . . oh well, sigh. http://www.aps.org/programs/outreach/resources/index.cfm http://www.learner.org/workshops/force/ http://web.randi.org/educational-modules.html https://engage.intel.com/community/teachersengage/showcase http://www.popsci.com/announcements/article/2010-03/new-browse-137-years-popsci-archive-free http://busyteacher.org/teaching_ideas_and_techniques/classroom-posters/ http://www.the-brights.net/action/activities/poster.html http://www.aps.org/programs/education/highschool/teachers/ http://www.weareteachers.com/lessons-resources/classroom-printables http://www.hhmi.org/biointeractive I found these and more than I have the time to enter. 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.
