This one is really cool. So many different kinds of science represented with lots of ideas of things to do. Highly recommended.

Have 2 minutes? Check out this local girl's video that won her $1000 in the "I am what I learn" contest sponsored by the dept. of education. Jordan is an eighth grader from Sammamish who raises chickens. What can you learn from a chicken? Watch and see.

Cold Weather Science

Well, the weather outside is cold and damp, so you are stuck inside and wishing you could be doing something more interesting. Maybe you are looking outside at the cold and ice, and you wonder to yourself…

Start with a Question: I wonder how fast I can cool my cocoa if I put it outside?

Investigate: Put some warm water (why waste cocoa?) outside and see how quickly it cools. Try a variety of samples with various containers, locations, and other variables you can think of (sun or shade, stirring or blowing, etc.).

Observe and Collect Data: Use a thermometer, watch, notepad and pencil to record how cold the water gets, and how long it takes, and what variables you changed for each of your samples (size of container, location, weather conditions, etc.).

Analyze: Did the water cool? How quickly? Did all the samples behave the same way? Were any of the variables important?

Interpret the data and draw conclusions: Do you think your cocoa would cool down if you put it outside? How long do you think it would take? Are there things you can do to speed it up?

Test it: Use the results to figure out the fastest way to cool your cocoa and see if it works. Challenge someone to a cocoa cooling contest and apply what you have learned to see who can cool their cocoa the fastest.

If you decide to do this experiment, share it with us! Post as a comment what you did, what your variables were and what results you got, or what you observed.

January Nights Can Dazzle

by Rodney Ash / Special to The Seattle Times



January is one of the coldest months and thus not the kind of weather that encourages you to linger outside. However, if there is no wind and you bundle up, you can enjoy some truly spectacular sights.



Mars reaches opposition on Jan. 29, shining at just a little brighter than magnitude -1 (the smaller the number the brighter the object), making it the third brightest starlike object in the night sky. Look for it in the east just after sunset, reaching zenith about midnight. You will quickly recongnize it by its orange hue. It makes an excellent target for the next three months.

Jupiter is sinking low into the west, and Sirius, the brightest star in the night sky, shines in the southeast. Also in the southeast, soon after dark, look for the constellation Orion the hunter. He is recongnized most readily by his three belt stars. Of the 20 or so brightest stars visible in the night sky, two of them are in Orion. Orion's right shoulder is the red super giant Betelgeuse. It clearly has a red hue and shines with a luminosity of 105,000 times that of our sun. Next find the blue super giant Rigel, which marks Orion's left foot and shines at a luminosity of 66,000 times that of our sun. It shines with an almost ice-blue light, particularly on cold winter nights, belying the fact that itis one of the hotter stars visible.
