Apparently, April 18th is the World Wide Day in Science. If you are involved in science, you are encouraged to submit essays, due May 18, about what you did on April 18. If you work with students, they may be interested to read the essays from this and previous years.
Speaking of science days, Astronomy Day is April 21. Take your kids outside to look at the sky (if this Nor'easter ever clears up!) For more guidance, visit the NASA site I referenced last week.
Now that you have viewed the Cosmos, take some time for the world around you. Earth Day is April 22. If you have not been watching the new Discovery Channel series on Planet Earth, you should check it out. Remarkable videos of nature - many never seen before moments.
