🔍 Experiment Of The Week – 9 Layer Density – by Steve Spangler

Density differences cause objects to “float” in liquids that are already stacked on top of each other.

With this science-magic trick, you’ll put a new spin on our famous Density Column demonstration. First, you’ll discover how to stack nine layers of liquids on top of each other. That alone looks really cool, but then you take it up a notch by making different solid objects “float” in the middle of all those cool looking stacked liquids. You’ll surprise yourself and your friends with what you can do with the 9-Layer Density Tower. Continue reading

Monarch Butterfly Tagging – submitted by Kent Cheesman

We are tagging the monarch through a program call Monarch Watch which is a nonprofit education, conservation, and research program based at the University of Kansas that focuses on the monarch butterfly, its habitat, and its spectacular fall migration.

This year our school has raised over 120 Monarch larvae. To date we have tagged and released 92 Monarch butterflies. Many students are intrigued by the program and have been contributing with larva found at home, providing milkweed to feed the larva and providing oranges and flowers for the Monarchs when they emerge from their chrysalis until there are released.

This endeavour has provided many educational pluses as students are very interested in the life cycle of not only the Monarch butterflies but also the many other “critters” they are finding and researching throughout our school yard. It has also been the starting point for many related classroom inquiries and writing activities as well.

Thanks so much for sharing Kent

Why Don’t Birds Lay Square Eggs?

What is ”egg-shaped” even? I used to think it was the shape of a chicken egg. Then one day I saw a collection of eggs from lots of different bird species, and I realized just how many different kind of egg shapes there really are! I had to know why. And it turns out a couple teams of scientists had wondered the same thing. Here’s what science says about why eggs are egg-shaped, if that’s even a thing, which I’ve learned it might not be. Evolution of bird eggs, go!
