Pi Day!

Happy Pi Day from all of us at the Bartlett Public Library! We celebrate today as Pi day since the pidate, March 14th, is the same as the first three digits of π (3.14).

You can learn more about the mathematical concept of Pi in Why Pi? by Johnny Ball, in our juvenile nonfiction section at j530.8 BALL.

You can celebrate Pi Day with challenges from NASA scientists and engineers as part of their Pi Day Challenge! Good luck!

Earth Science with Edna

This is our new friend, Edna.

Her hobbies include reading, exploring, and watching the latest Disney movie with a big bucket of popcorn.  Her most favorite activity is learning about science and experimenting with ideas.

Edna’s latest area of interest is gardening.  She loves the smell of flowers and enjoys eating lots of different fruits and vegetables- except for Lima beans!  She would really like to have her own garden, but she’s not very good at keeping even a cactus alive!

Lately, she has been reading about a different way of growing plants called, hydroponics.  Hydroponics is a way of growing plants without soil.  How can this be?  Edna always thought that soil was needed to make plants grow!  Technically plants need soil for its nutrients and as support system for its roots to hang on to. SO…if you put the nutrients that the plant needs right into the water and if you have something to support the plant and its roots, the plant won’t need the soil.  It’s very scientific and Edna needs to do some more research.
