Kirigami Parachute
One of my favorite things is when art and science intersect to create something new and unique. Scientists recently discovered that the three thousand year old art of paper cutting called Kirigami can be used to create a better parachute. I've included a template that you can print out on a piece of construction paper to create your own. The template is just one way to make one and is provided to familiarize you with the basic parts. Here's a link to the original video of the scientists that came up with this https://youtu.be/6rrDW6YIbXI

We just did this at home! The parachutes were super effective. We will try some other shapes and colors!
Win at "I Spy" every time!
Here's a method to always win at the game, I Spy, and at the same time secretly learn about something called exponential decay. A mathematical concept that applies to everything from the cooling of a cup of coffee to radioactivity decay.

I just realized - this is how Earthbender traditionally identify the new Avatar in the last airbender. They call it directional geomancy
Don't play with matches SOLUTION!
Here's a solution to the matchstick game that asks you to create a 4 unit continuous area using exactly 12 matches, a bit tricky if you don't know a little Pythagoras.

Oh man! Lu and I worked on this one a long time. Didn’t get it. Will try again using some triangles
The Multiplication Game
Math facts aren't that much fun to learn but they're necessary to develop fluency. Here's a fun way to gamify the Multiplication Table. My daughter and I played this and she loved making the cute faces. She brought it to school and showed her teacher who asked me for the worksheet. My kid gave a presentation to her class about how to play and now it's an activity they have in rotation. I attached the worksheet as a PDF you can download and print out

We didn’t get too close on our first try…
Do Science, Save the World
I wanted to demonstrate how anyone can use a little science to drive change. This is a simple science experiment that started with an observation - there's always a little water left in a water bottle. The result is if 1/4 of all discarded water bottles have a small amount of water left in them and the cap is not taken off, then we are losing an Olympic-sized swimming pool every 12 hours. That's the amount of water needed for 8 million people lost every year. Not good, but people don't know. See for yourself and spread the word.

Very cool problem solving. When you go through the steps of making the estimate yourself it’s easier to remember the numbers and what they mean too. That’s a lot of water to waste!
