Scale of the Universe 2 is a great tool to show the size of items from any subject from biology to astronomy. Even if you do not teach any of those classes, it is an amazing website to explore for any age level or subject.

Compare yourself from anything from a quark to the monstrous VY Canis Majoris star by going to Scale of the Universe 2.

Every once in awhile I come across a website that makes me say, "Holy Smokes! That is just plain old awesome!" Well, Appear.in definitely falls into that category! Appear.in allows up to 8 people to have a video chat and share their screens without having to login to a website or install complicated software. The website just plainly works and is a lot of fun.

For educators the possibilities are endless. It could be used for those ever popular Mystery Skype sessions, it could be used to allow students to meet in groups outside school hours, it could be used to share a student's Chromebook screen on a projector, and there is so much more amazing potential! 

Watch the demo people to see how Appear.in works to both have a video chat and share a Chromebook screen.

Below is a curated list of Halloween activities that can be done on any PC, laptop, or Chromebook. I broke them down into four different categories to make it easier to find an activity that is right for your classroom! 

Every so often an educator has a need to flip a coin. It could be trying to decide if they get hot lunch or chance eating that mystery left over in the lounge fridge, or maybe they are trying to settle an argument between two students about who gets to use the Crayola crayons and who gets the Roseart. 

Well thanks to technology, we have digitized the quarter. No longer will we have to carry around with us a coin or two for these types of emergency. But why stop there? Why not also try out some of the amazing virtual dice out there!

Here are five websites for all your needs: Coins and Dice OneTab. Want to see these sites in action? Check out the tutorial below where I highlight the inner workings of each website.

DustBin is a great resource from Classtools.net that allows you to create an interactive educational game. You can customize it for any subject and/or topic. It is also easy enough for students from young and old to create their own. This game can also be used on Windows, Mac, and Chrome OS devices. 

Another bonus feature of this web based game is that it can be embedded on your own website. You can see an example of this above, well, unless you are on an iPad, because unfortunately it does not work on iPads. To see how easy it is to create a DustBin game, check out the brief tutorial below.

Do you have that special person in your life who always takes that simplest task and makes it ten times more complicated than it needs to be? Well if so, they may be great at creating Rube Goldberg machines.

A Rube Goldberg machine is a machine that takes a simple process and makes it a multi-step process. Why? Because it is fun! Here are two great websites to introduce Rube Goldberg machines to your students. 

Goldburger to Go is a PBS Kids activity that challenges students to move a hamburger from point A to point B. Students will have to learn via cause and effect to solve this Golberg puzzle.

Burglar Catcher is another Golberg type puzzle, but this one adds a nice layer of physics to the mix. Students have to adjust several simple machines to accomplish their goal. 

After challenging students to solve these puzzles, enjoy the below music video featuring a very complex Rube Goldberg machine.

Nothing made a long car ride go by like a new book of Mad Libs when I was a young kid. It was always fun to come up with new ways to state the word yuck, fart, or booger. In retrospect, I was kind of immature. Well, now Mad Libs can be done virtually anywhere and tweaked to fit in your classroom using these two awesome Mad Lib generators, WordBlanks, and Project Labyrinth. Both websites make creating and sharing your own Mad Lib easy. This could be great tool for teachers and students to create interactive projects and reviews.
