Science of the Summer Olympics: measuring a champion

As Official Time-Keeper of the 2012 Olympic Games, Omega’s high-tech timing devices have come a long way since the 1932 games in L.A. where athletes were timed to the nearest one-tenth of a second. The company brought thirty “official” stopwatches to those games to be used in all timed events. (Until then, timekeepers brought their […]

Seasonal changes vary across the many climates in the United States. If you get temperatures below 40°F for extended periods of time, you can plant these […]

Citizen science: collaborative projects for teachers and their class

I was excited to see a Monarch butterfly land on the Butterfly Bush in the yard (I hesitate to call it a garden). Does that mean that the Milkweed plant may yet become a home to Monarch caterpillars? I haven’t seen any eggs but there is still time. Maybe another insect has already staked a […]

Connecting to the weather

Can you tell that it will rain soon by the way the air smells? Do you like the smell of snow? I like the way the air smells just as a badly needed rain begins—it makes me think of the earth exhaling as the water soaks in (but this could be a misconception on my […]

Snack sorting! It’s an interesting way to involve students in classifying and, while sitting together to eat, there is time to talk about why certain groupings were chosen. Children might sort by shape, create an ABAB pattern, and count the number of each snack shape. Classification is the theme for the March 2009 issue of Science and […]
