Apps: Ways to engage, and educate, kids

Are you worried that your teenage kid's brain will revert to hibernation mode during summer break? From video lectures to virtual museums, to educational opportunities that are truly out of this world, here are some apps that can inform and entertain your kids this summer.

(iPhone, iPod Touch, Android; free)

The world's greatest collection of modern art can now fit in the palm of your kid's hand with these free applications. They include tens of thousands of digitized works found in the Museum of Modern Art in New York City. The app also includes background information for many artists and multimedia tours of the museum's galleries. If your kid visits the museum, the app provides audio walking tours and the ability to create customized playlists.

Khan Academy

(iPad; free)

School is always in session at Khan Academy, which offers short video lessons that cover topics from the Bay of Pigs invasion to Newton's First Law of Motion. Started by former hedge fund analyst Salman Khan, the academy is a collection of thousands of YouTube videos that Khan has produced in recent years. Each video follows a simple format, with Khan providing a voice-over to visual examples he presents on a virtual blackboard. It's never too early (or late) to get exposure to the subjects covered in Khan's lessons. The app is free to download and won't hit you up with any subscription fees thereafter. While there is no official version of Khan Academy for Android devices, there are several independently produced apps that curate his video lessons on that platform as well.

Sometimes it's a good thing for kids to space out for a while, particularly if they can learn about the origins of the universe. That is the goal of the free and official NASA app, which includes mission information, over 150,000 images and videos.

A Visual Exploration

(iPad; $6.99)

The periodic table comes alive with this beautifully designed and engaging application, which showcases every chemical element in animated and three-dimensional glory. The app includes the back story of every element and how each one fits into the world.

With its cool products, Apple is hot, so perhaps it's fitting a thermostat is available at its online store. The Nest is, like Apple products, sleek, high-tech and expensive ($250). While a thermostat for your home is an unlikely product for Apple to sell, there are connections: Nest can be programmed from Apple devices and the company's founder is a former Apple designer who helped create the iPhone and iPod.
