I have been slow to post here, but found this resource a few weeks ago and knew that I would NOT forget the address. Well, I did, and it is such a rich resource, that I am going to post about it.
It is Gooru Learning. 
This site is filled with links to lesson plans, interactive resources and videos. I think it really is the most interesting site for finding good places for students to learn.

Founders or Traitors

Typically, the use of Colonial Williamsburgh's materials are expensive, however, they are going to give a free year's use of a virtual field trip. There is on demand video streaming over the web about the subject, students can email John Adams and there are interactive online games as well as lesson plans. Definitely worth signing up for.

Wind Turbines - National Geographic

Learning about Wind Turbines?

This website will give you a good interactive learning explanation on what makes a turbine and how does it work. You can change many variables of the turbine to see how that will impact the energy production.

E is For Explore
E is for explore is a great place to find new ways to bring math and good design in one place. I recommend that you go and check this site out. This would be a great place to find good ideas for math and science centers in your room!

A site that is offering a lot of great online content arranged by subject and worth checking out for the middle school to high school student is  Gooru.The library covers 5-12th grade Math and Science courses, and they are expanding to subjects like History and English Language Arts in the near future!

They sent me a message saying that they are starting with a new collection, Intro to American Government. Don't miss the interactive tour of the White House. 

Gooru has organized links that exist elsewhere, but it should really help when you are trying to organize your curriculum. 

I just read that Ted Talks is now making animated lessons about certain subjects that teachers might want. It has just begun so there are limited movies, but the ones that are there are very interesting. It looks as if it might be a free version of Brain Pop. Certainly worth checking out. http://ed.ted.com/
I just watched the one on the atoms! Worth checking out.You can turn the videos into an assignment where the student would watch the video and then take a quiz. This can be customized by you.

Lawrence Hall of Science

This is a science site for kids, 24/7 Science. http://www.lawrencehallofscience.org/kidsite/
It has some great science games and questions that elementary kids would find interesting.

TES Iboard

A great find - TESiboard is a good resource for tools that you can use with your Smartboard or at your computer.  It is a site from England that has lots and lots of math and literacy tools, especially for the younger grades. They have made it so you can easily link to the one activity on your website. If you are working on having a class website, this could be a great resource.

PBS Learning Media

It has been a long time since I have posted, but this site is one that is worthwhile bookmarking. PBS Learning Media has made an interface that allows for you to search through their resources for audio, documents, video, interactives and pictures. You can make an account so you can save your favorites. There doesn't seem to be a downloadable option for the videos and interactive, but the fact that you can save them in a favorites folder seems to be a good option. The price is right, free. They are going to offer a premium package for districts later, but being able to search for the interactives that PBS has in one place, is worth exploring.

Weather Forecasts, History of Weather

This site, WeatherSpark, is a new site that allows you to see the latest weather forecast for where you live. However, the part that is terrific about this site is that it also allows you to see and compare what weather was a week ago, months ago, years ago! You could go to this site and see what what the weather was like on the day that you were born.
It will allow you to create graphs and compare them. I think that the students would love this. I know I find it fascinating!
