Share It! Science and Growing with Science are thrilled to announce we are teaming up for a week long Children's Science, Technology, Engineering, Art, and Math (STEAM) Festival all next week. Please join us for information and project ideas to help you explore STEAM-related activities for the summer and beyond!

Our STEAM activity schedule is as follows:

June 22:  Science
June 23:  Technology
June 24:  Engineering
June 25:  Art with a STEM focus
June 26:  Math

We would love to hear your questions or suggestions for STEAM-related projects to share with others. If you choose to, please leave your ideas in the comments and we'll add the links to the appropriate days.

## Activities to Celebrate Pi Day

What is Pi Day?

Pi Day has been celebrated each year on March 14 (3/14) as a fun salute to pi = 3.14...  This year, Pi Day will have special significance because 3/14/15 at 9:26:53 a.m. and p.m. will represent the first 10 digits of pi. Plus, March 14 happens to be Albert Einstein's birthday. Cool!

What is Pi?

Pi is is the ratio between the circumference (distance around a circle), and the diameter (the distance across the circle). It written as p in Greek alphabet, which is the symbol π. Pi is an infinite decimal with a value 3.14159265358979323846…

Want more details? SciShow has an explanation of pi useful for older students.

## Activities for Pi Day:

1. Baking

It has become somewhat of a tradition to bake a pie to share for Pi Day with a π symbol on it. Another option would be to make π pancakes. See how to make them at Pi Day Pancakes  (Your Individual Taste).

2. Toothpick Toss

One way to calculate pi involves comparing the circumference of a circle to the diameter. Another way is to count how many toothpicks (or other similar objects) fall in a certain way when thrown at a series of parallel lines.

Gather:

• Toothpicks (matchsticks also work) - at least 100
• Cardboard or poster board surface to draw lines on
• Ruler
• Marker (such as Sharpie)
• Calculator (optional)

Draw several parallel lines on the cardboard or poster board with the distance between each line exactly equal to the twice the length of a toothpick. Randomly toss toothpicks onto the lined surface, keeping track of the total number of toothpicks tossed. When you are done, count each toothpick that has landed crossing a line in any way.

Divide the total number of toothpicks tossed by the number of toothpicks that crossed the lines. See how close to pi your estimate is.

For more details and slightly different methods, check Estimating pi by dropping sticks (with a simulation to try) at SciFriday. Exploratorium also has a discussion the toothpick toss and other Pi Day Activities.

3. Read a Pi Day Book

Sir Cumference and the Dragon of Pi (A Math Adventure)
by Cindy Neuschwander and illustrated by Wayne Geehan

Meet the regulars in King Arthur’s court, such as Sir Cumference, his wife Lady Di of Ameter, their son Radius, and the carpenter, Geo of Metry. When Sir Cumference turns into a dragon, can his family and friends use math to save him? Although it looks a bit like a picture book, the concepts are actually for middle grades.

This video shows a reading of the book.

For more book suggestions, check the list of Math Books for Pi Day and Every Day at Science Books for Kids.
