Falling Faster Than the Speed of Sound

Earlier today Felix Baumgartner survived his sky dive from more than 24 miles above the Earth's surface. In doing so he became the first person to break the sound barrier without an engine. The Red Bull Stratos website is packed with information about the science and technology involved in the jump. Two videos from the site that might be of interest to science teachers and their students are Speed of Sound Explained and this video about the balloon that lifted Baumgartner more than 128,000 feet above sea level.






I recommend visiting Larry Ferlazzo's blog for a list of graphics and images outside of the Red Bull website. I particularly like this infographic that Larry listed.

Math vs. Zombies - A Halloween Math Game

Math vs. Zombies is a free iPad game with a Halloween theme. The game is has three virtual worlds each containing ten levels of basic math problems. The object of the game is to correctly solve as many math problems as possible before the zombies catch you. The math of the game is basic addition, subtraction, multiplication, and division.

Applications for Education
If you're comfortable having your students play math games that have a zombie and Halloween theme Math vs. Zombies offers engaging practice activities. Tap to Learn, the producers of Math vs. Zombies, offers a few non-zombie math games if you're looking for something else to try on your iPad.

Tap to Learn Grammar App

Tap to Learn produces educational apps for Android and iOS. I recently installed their Grammar app on my Nexus 7 tablet. The Tap to Learn Grammar app for Android offers more than 200 self-paced grammar lessons. The lessons don't have videos embedded in them, but there are links to external videos hosted on YouTube. After working through a lesson students can test put their new knowledge to the test in quizzes that provide instant feedback. The app records students' progress for them.
Applications for Education
Using Tap to Learn's Grammar app isn't a revolutionary approach to learning. That said, if you're looking for an Android app that your students can use to practice and track their progress in developing their grammar skills.
