Cells make up you, your friend, your hamster, and your mom's broccoli surprise. If it's alive or ever was alive, it is made of cells. Space scientists looking for life on Mars are trying to find microbes made of simple cells—not little green men—and biologists who search for cures to diseases work with cells. Small as they are, cells determine how life unfolds from its beginning to its end.

Teen Tech Week: Libraries Are For Creating, March 4-10

I think. I create. I invent. Create it at your library during Teen Tech Week, March 4-10. Our branches offer teens a space to explore, create, and share while extending learning beyond the classroom. Joining in the fun is easy! Teens in grades 6-12 are invited to drop by the teen area anytime during the week and get creative with special activities just for Teen Tech Week.  Share your creations with your friends and with us by mentioning Central Rappahannock Regional Library on Facebook, or @crrlnews on Twitter and Instagram using #TTW18.

CRRL Guest Picks: Daniel Wallace--Engineer, STEM Teacher, and Musician

Dr. Daniel Wallace is a human factors engineer for the U.S. Navy. He is active in teaching science, technology, engineering, and mathematics (STEM) to children through demonstrations and teaches a science camp for a week every year at Oak Grove Baptist Church in Colonial Beach, VA. He is now in his 14th year as a member of the Westmoreland County Public School Board. He is also a musician, playing violin in the praise and worship band at his church.

We are very happy that he has agreed to share some of his favorite books with CRRL readers. To begin, here are favorites from his childhood:

Cover to Caroline’s Comets: A True Story by Emily Arnold McCully

Caroline Herschel had a very hard life early on. Born into a family of royal musicians in what is now Germany, two childhood illnesses left her face pockmarked and her body stunted. Her mother treated her very much as a servant while worrying that no man would ever want to marry her. In the 1700s, this was a real concern, for it was hard for women to make enough money to survive on their own. Caroline's life was pretty miserable as she was expected to do exhausting housework, including knitting stockings for everyone, over and over again.

Fortunately, Caroline’s older brother William wanted to help her. He had moved to England where he was working as a choral conductor and piano teacher. William had the idea that Caroline could learn to sing and be paid for it, and that is exactly what she did. But that is not where her story ends.

Cover to Over and Under the Pond

A boy and his mother are canoeing on a pond in the Adirondack Mountains. It is peaceful place, maybe even dull. Or, is it? The boy asks his mother, “What’s down there?”

So many things! His mother tells him about them, from the minnows, crayfish, and bullfrogs to beavers hunting “delectable roots” found in the mud and otters clawing for freshwater mussels.

And, over the pond? A great blue heron catches one of those minnows for his dinner. A moose munches a mouthful of waterlilies. As the sun sets, mother and son paddle back to shore and head for home. In the dark, life goes on at the pond. Raccoons come out to prowl, and catfish glide as they seek their suppers in the cool of the night.

Kate Messner’s Over and Under the Pond does several things very nicely. First, it tells a soothing story, perfect for bedtime. But it also introduces an ecosystem, making the science of living things and the secrets found below a pond’s surface very accessible, and it manages to do so without sounding like a textbook.

"Look, Mom, a shell! A beautiful shell!"

If you go to the beach this summer, you may find dozens of seashells, each uniquely wonderful. Plan on filling a whole jar with your favorites: scallops and angel wings (piddocks), whelks and sand dollars.

Cover to Rosie Revere, Engineer by Andrea Beaty

Rosie the Riveter is an icon, well-known for representing the scores of women who worked in munitions factories during World War II. Andrea Beaty gives a subtle nod to the original Rosie—and the powerful women she represents—in Rosie Revere, Engineer, her follow-up to Iggy Peck, Architect. Rosie Revere is a born engineer who loves creating intricate and unusual machines using parts she has salvaged from the trash. Her inventing has been a secret, though, ever since the day her Uncle Fred laughed at her snake repellant hat.

Fabulous Friday: Sharks!

The CRRL is celebrating these “fin-tastic fish” at Fabulous Friday STEM classes in July for grades K-6. You will find out how sharks help maintain healthy oceans, range in size and shape, are threatened with extinction, and more. This is one of many activities that will help you complete the Shark Week mission and earn a badge and points for Summer Reading prizes.

Cover to The Elements: A Visual Encyclopedia of the Periodic Table

DK Publishing and the Smithsonian Institution worked together to create a fascinating book for kids (and adults) who are fascinated by the world around them. The Elements: A Visual Encyclopedia of the Periodic Table makes what could be a dull subject very shiny indeed.

Sure, you have your basic periodic table for quick reference. But every element gets its spotlight, with truly interesting facts and many intriguing photos. Take iridium. It’s a shiny black metal that’s 22 times as dense as water. That’s heavy. You can find it in meteorites, compasses, the Chandra X-ray Observatory, and Badlands National Park in South Dakota.
