For a complete introduction and to get to know each Quirkle, work your way across the main menu bar above. Have fun exploring, and please contact us with any questions you may have!

But that's not all. Check out the introductory video that explains why we created the Quirkles, or take a look at the sample book Gilbert Gas below.

March may be fickle as far as weather goes, but it’s a month full of great teaching ideas. Of course there is Dr. Seuss’s birthday, Johnny Appleseed’s birthday, the first day of Spring, and St. Patrick’s Day. We figure you have those covered. But if you want some new inspiration, we’ve got some other fun things for you to think about too!

Did you know that March 13 was the day the planet Uranus was discovered? How about some interesting facts about this planet? For example Uranus is the coldest planet in the Solar System. It also makes one trip around the Sun every 84 Earth years. During some parts of its orbit, one or the other of its poles point directly at the Sun and get about 42 years of direct sunlight! The rest of the time they are in darkness.

Or how about celebrating Albert Einstein’s birthday on March 14? Have a “no socks day.” Part of Einstein's charm was his disheveled look. In addition to his uncombed hair, one of Einstein's peculiar habits was to never wear socks. Whether it was while sailing, or to a formal dinner at the White House, Einstein refused to wear socks. To Einstein, socks were a pain because they often would get holes in them. Plus, why wear both socks and shoes when one of them would do just fine?

Did you know the third week of March is American Chocolate Week? Try the Quirkles’ “Vinnie Volcano’s Chocolate Meltdown.” Not only does this illustrate how rocks melt, it also allows for a tasty way to measure different melting times. Try dark chocolate, white chocolate and milk chocolate. Graph the results.

Not healthy enough? (We’d beg to differ!) It’s also broccoli month. Read Botanist Bert and learn how Bennie Bear confuses broccoli for a very bizarre basketball. (Yes, you can tie in some Johnny Appleseed activities to this lesson too!)

And if that’s not enough, March 30 is National Pencil Day. Like so many technologies we take for granted, imagine life without the pencil. Do you know your pencil trivia? Beloved author Roald Dahl used only pencils with yellow casing to write his books. He had six sharpened pencils ready at the beginning of each day and only when all six became unusable did he re-sharpen them. Speaking of yellow, do you know why most pencils are yellow? Check this out and other trivia here:

As for Quirkles activities, we just couldn’t pass up the opportunity St. Patrick’s Day offers. How about a lesson in color mixing (Colorful Caroline) to come up with St. Patty’s favorite color green? Or take a look at our water absorbing “Pot of Gold” activity. And of course we had to make a leprechaun’s potion for you to share! These and all our other fun experiments can be found via our e-newsletter/website resource pages or on our Quirkles® YouTube channel!

Happy March teaching!

What do blood and the city of Venice have in common? They both operate the same way: they are both a "floating city," if you will. Blood moves in a circular maze through the body, 24 hours a day, through a series of arteries, veins, and capillaries. The average person has about 1 to 1½ gallons (4-6 liters) of blood. The body makes blood-- red blood cells, which carry oxygen, white blood cells, which fight infections, platelets, which are cells that help stop bleeding, and plasma, a yellowish liquid that carries nutrients, hormones, and proteins throughout the body. And at the "heart" of the circulatory system?  The heart of course as it pumps our blood!

Speaking of blood, here are some more interesting blood facts:

While humans have red colored blood, other organisms have blood of varying colors. Crustaceans, spiders, squid, octupuses, and some arthropods have blue blood. Some types of worms and leeches have green blood. Some species of marine worms have violet blood. Insects, including beetles and butterflies, have colorless or pale-yellowish blood.

Human blood contains metals atoms including iron, chromium, manganese, zinc, lead, and copper. You may also be surprised to know that blood contains small amounts of gold. The human body has about 0.2 milligrams of gold that is mostly found in the blood.

It is well known that white blood cells are important for a healthy immune system. What is less known is that certain white blood cells called macrophages are necessary for pregnancy to occur.

 Matured human blood cells have varying life cycles. Red blood cells circulate in the body for about 4 months, platelets for about 9 days, and white blood cells range from a few hours to several days.

The most common blood type in the United States is O positive. The least common is AB negative. Blood type distributions vary by population. The most common blood type in Japan is A positive.

February, the month of valentines and hearts, seems to be a great time to explore, with the Quirkles Yawning Yolanda, our amazing human body, and more specifically our circulatory system. Don't forget to try our tasty blood model activity too!


We just couldn’t pass up a St. Patrick’s Day science teaching opportunity. This month we make a “leprechaun’s potion” for you to share. Check this and all the other fun experiments out via our newsletter archives or Quirkles® YouTube channel!

This is the month of hearts and candy.  We look at both and learn about the components of blood.

What People Are Saying

It is very hard to put into words exactly how much I love the Quirkles. They totally changed my attitude about teaching science to kindergarten and first graders as an enrichment class in my school.
