Environmental Science: What to do during the cold winter months – by Dave Gervais

Source: Even during the winter, there are some wet swampy areas that defy freezing. Sometimes it’s the current; sometimes it’s the heat from decomposition that keeps the water from freezing. Alternatively chopping through ice in a shallow swampy are would also give you access to the bottom detritus. A sample was taken from my backyard pond on Dec 10th.

Sample: When taking a sample, ensure that there is plenty of vegetation. Some will still be green. You may find Duck Weed, or some kind of filamentous algae. A 500 mL sample will provide enough material for several classes. I re-purposed a used blister pack to act as well slides for this activity. When glued to popsicle sticks, my mechanical stage easily gripped this. That allowed me to have 6 samples on the stage at once.

Thanks for the great ideas Dave!!!!!!!!!!!!!!!

Stay warm

 

Marshmallow Masher – Sick Science!

Marshmallows are a delicious, fluffy staple of summer, campouts, and barbecues. Did you know that there isn’t really much to them? It’s true. The best way to see what really comprises a marshmallow is to put it to the Marshmallow Masher pressure test. You’ll use the power of air to demonstrate what you’re really eating when you roasting ‘mallows this summer. Want more experiments like this?

🔍 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
