NASA Shows Us the Earth As Art

Earth As Art is a beautiful collection of NASA satellite imagery of places all over the globe. The collection is available to view in a PDF (link opens PDF) or in the NASA Earth As Art iPad app. Earth As Art includes nearly 150 pages of imagery and explanations of the imagery so that you know what you're looking at. Browsing through Earth As Art is a nice way to see some of the truly unique features of the Earth's physical geography.

A Google Map of Plant and Animal Life Cycles

The USA National Phenology Network has built an interesting map of plant and animal life in the United States. The map allows you to see where various plants and animals have been observed and reported to USA NPN. You can search the map by animal, plant, or location. The map includes a timeslider that can be used to visual the life cycles of the plants and animals on the map. Users of the map can add climate overlays to it too. Click here to read the documentation on how to use all of the map's features.

Applications for Education
The USA National Phenology Network's map of plant and animal life could be useful for helping students see the biodiversity of the United States. Turn on the climate overlays to help students see the relationships between climate and plant and animal life.

Fun Snowy Activities for Students and Teachers

In my previous post I shared a video about the chemistry of snowflakes. Writing that post reminded me of some ideas that I've shared before for fun outdoor winter activities with students. A few of these could be tied into basic physics lessons.

NOVA, as a part of their program on Denali, has directions for building a snow cave and directions for building an Igloo.

Boys' Life offers a list of outdoor winter games as well as directions for building igloos and snow shelters.

Making your own snowshoes is an activity that can be done indoors with the final product enjoyed outdoors. Mother Earth News offers directions for making your own snowshoes. How Cast has video directions for making an emergency pair of snowshoes.

In the video below BBC Survival Expert Ray Mears teaches viewers how to make an igloo and what igloos were traditionally used for.

When I was about seven or eight I was given a copy of The American Boy's Handy Book(Amazon link). That book is filled with fun hands-on indoor and outdoor activities including an entire section devoted to snow forts and other snow-related activities.

The Cool Chemistry of Snowflakes

In my neighborhood we've had at least some new snow every day this week. Just a little north of me there has been nearly two feet of new snow this week. The latest video episode from Bytesize Science nicely matches this week's weather in Maine.

The latest episode of Bytesize Science explains how snowflakes are created. The two minute video is embedded below.

3 Ways to Explore Marine Life in Google Earth

Google Earth is a great tool for exploring many aspects of geography. One of the features of Google Earth that seems to be frequently overlooked is the ocean imagery. Using Google Earth tours can be a good way for students to learn about marine life and habitats. Here are three good resources that you can use for that purpose.

To get started take a look at a look at this list of ocean tours featured on the Google Earth showcase. Some of these tours will also work in the Google Earth browser plug-in. Learn about protected whale areas in the tour below.

The Encyclopedia of Life offers four Google Earth tours of interest to teachers and students. One that I particularly like is the Atlantic Bluefin Tuna Tour. The tour of the Artic Tern migration patterns is featured in the video below.

The Encyclopedia of Life also hosts an interesting interactive quiz using Google Earth. The Encyclopedia of Life's Google Earth Species Quiz (opens KMZ) presents players with images of an animal and the animal's name scientific name. Players then have to pick the place that the animal is from. If the correct answer is chosen, the player is zoomed to the correct location on the map. 

NOAA offers dozens of Google Earth files and demos related to weather and marine life. You can find the list here.

Bonus: Not Google Earth, but quite cool.
Ocean Tracks is an Australian website on which students can view the tracks of marine animals in an online 3D environment. The "tracks" part of Ocean Tracks shows you where in the world tagged animals are swimming or have swum. Ocean Tracks uses the Unity browser plug-in to provide animations of the underwater views of tracked animals. You can see what bluefin tuna, swordfish, sharks, and many other fish see in 3D.
