When the moon’s minimal, go outside and look up! You don’t even need a telescope. Try to find a space away from city lights, and enjoy it with a friend.


Some meteor showers are more spectacular than others. This one is expected to pick up tonight 4/20 and tomorrow 4/21, and we’re expecting to see between 10 to 20 meteors per hour at the peak. You’ll want to look near Vega, use a stargazing app to help you find it.



Comet Thatcher is the source of the meteors for this particular meteor shower, because every year in late April our planet will cross the path of this comet. The last time it visited the inner solar system was in 1861, so it hasn’t been here in a while, the orbit is about 415 years.


Comets leave a trail of particles, and when the Earth sweeps through that particle trail, we get meteor showers! That’s why meteor showers are stronger some years and not as much in later years. The years they are strongest is when the comet has made a recent pass!


No kidding! With this advanced experiment, you’ll be able to show your friends this super-cool magic show chemistry trick with very little fuss (once you get the hang of it).


On March 14 at 1:59pm, folks from all over the world celebrate “Pi Day” with games, activities, and pie-eating contests. Here are my best resources for showing kids how pi shows up in the real world and also how to learn about pi in a way that not only makes sense but isn’t flat boring.


Pi (p) is a number slightly greater than 3 that shows up when you divide the circumference of a circle by its diameter, no matter what size the circle is. It also shows up in other shapes like spheres, ellipses, cylinders, and cones as well as unusual places like summation series, number theory, probability, bell curves, and the Fibonacci series.


I’ve prepared two different versions that you can access, and each comes with its own video. If this is your first time encountering “pi”, then start with the first one. Otherwise, jump in to the full version and have fun!
