The (Revised) Calendar of Science Holidays

(Note from Julie: Well, Blogger and I had a falling out over my previous Calendar of Science Holidays. So, I thought I'd recreate the post here. My apologies to those kind folks who commented on the previous version and sent me new holidays. Please add your comments or any link corrections here. Thanks!)


Each year holds a wealth of weird, wacky, and interesting -- yet under-celebrated -- days for science, like World Meteorological Day and World Water Day. I decided to put together a calendar of annual science holidays and special events that celebrate science so that we could enjoy them together.

National events listed here refer to the United States, unless otherwise noted. Of course, if you live outside of the US, you are more than welcome to celebrate with us! (And I'll admit, some of these holidays are a little less "official" than others.) I expect to update this post in the future, so feel free to send me your special day and I'll add it to the list. Thanks!

Kids' Science Challenge

Would you like to see a scientist work to solve a problem or experiment that you designed? If you live in the U.S. and are in grades 3-6, you've got six days left to enter the three science contests presented by Kids' Science Challenge.

Let's say that you like astronomy. You can enter the Sports of Mars contest. In the future, astronaut explorers might colonize Mars. What kind of games could people play there? How would the Martian climate (dusty, with less atmosphere than Earth) affect the ways sports and games are played?

If Mars isn't your thing, check out the Detective Science Challenge ("Can you think of an everyday mystery that you can solve with the scientific tools of detection?") or the Bio-Inspired Designs Challenge ("Birds inspired airplanes. Seed burrs inspired Velcro. What part of nature will inspire your new invention?")

Visit the media arcade for inspiration. You can enter one idea for each contest! If you have a winning submission, you will get to work with a scientist to put your idea in action. And, your entry could win one of these awesome prizes, including a week at Space Camp, a bionic eye, or night vision goggles.

The entry deadline for all three contests in the Kids' Science Challenge is February 28, 2010. You can enter individually or as a team. You will have to describe your idea and tell how you came up with it; a sketch of your concept is optional. Complete rules are listed here; you'll need to register first. The official entry form (this is a .pdf file) can be mailed, faxed, or submitted online.

Good luck!

Butterflies on the International Space Station!

There are butterflies in space! Painted Lady larvae and three Monarch caterpillars are currently orbiting above us, after recently traveling to outer space aboard the Space Shuttle Atlantis. The "butterflynauts" boarded the International Space Station yesterday.

You can track the progress of the Painted Lady butterflies via Twitter (@ButterflySpace). Teachers can download a free teacher's guide and register for email updates about the mission. There's also a specific thread for teachers on the BioEd Online web board devoted to this experiment.

From the Butterflies in Space website at BioEd Online:

"On November 16, 2009, Painted Lady butterflies [flew] aboard Space Shuttle Atlantis to the International Space Station (ISS). The butterflies will spend several months in space as part of an exciting experiment to observe their life cycles and behaviors in microgravity. We invite your class to participate! The butterflies will live in a special habitat, which provides a safe environment, food and water. Photos and video will be transmitted back to Earth and made available here ..."

But Painted Lady butterflies aren't the only insect space travelers this time. Monarchs are up there, too! Through Monarchs in Space, Monarch Watch is documenting the progress of the monarch larvae. You can download some wonderful instructional data from this site along with links to other fun stuff like these recent pictures of the monarch caterpillars in space.

This current set of butterfly experiments builds upon previous work by BioServe Space Technologies, which has designed experiments in space since the early 1990s (including space flights for spiders, ants, and silkworms).

This video describes some of the challenges that the butterflies may face in their new habitat:



Enjoy!

Frog Egg MassPhoto credit: Pete Pattavina, U.S. Fish and Wildlife Service
My new friend Steven, over at Tropical Biodiversity, recently blogged about his rare pajurá de Óbidos (Pouteria speciosa) seed. He was concerned when the seed didn’t germinate – until he found out that he’d planted it upside down! Happily, when he turned the seed over, nature took its course and the seed is now a seedling.

Seeds aren’t the only “babies” with a top and a bottom. Recently, I watched a Discovery Channel show with a similar theme. A mama crocodile had laid her eggs too close to humans. Someone wanted both the crocodile and the eggs moved because every time anyone came near the nest, the mother croc would hiss at them. But moving crocodile eggs is a delicate business. If you turn the eggs the wrong way after a certain point of development, the little incubating baby crocodiles will drown. Australia’s Billabong Sanctuary discusses this on their Conservation & Breeding Projects page. Happily, most of the eggs in the story I was watching survived to hatch safely inside an animal sanctuary.

Frog eggs are a little more resilient. Soon after they are fertilized, frog eggs are known to align with the gravity vector (in other words, they have an up and a down). It was once believed that this rotation was crucial to their development, but recent studies of frog egg development in outer space have shown that this may not the case.

[Sidenote: If you’d like to learn more about animal studies in space, be sure to drop by NASA’s Astrobiology page. You can always Ask an Astrobiologist your questions! Also, Space Today Online has an interesting timeline of animals that have gone into outer space – an impressive list that includes not only frogs, but dogs, monkeys, rats, mice, and worms (among other critters).]

Scats and Tracks

If you live in the US, or you are planning a trip here, be sure to pick up a Scats and Tracks guide (published by Falcon Guide) for your region of the country before going on your next hike. If you are like me, you never see any actual wildlife during your foray into the natural world. Scats and Tracks solves this problem. Now you can look for animal "footprints" and poop instead! These little books, covering 70 species apiece, fit easily inside a backpack. My only complaint is that I would prefer to have color photographs of the animals, rather than black and white line drawings, on the off-chance that I actually spot some real live wildlife!
