Very Bouncy Science - and History

 

Bounce! A Scientific History of Rubber 

by Sarah Albee; illus. by Eileen Ryan Ewen 

48 pages; ages 6-9

themes: rubber, science, invention

 It can bounce, bounce, bounce!

Rubber has been around for thousands of years, and chances are that you’ve got some in your dresser drawer or maybe even your pocket. Where that rubber came from, what makes it so stretchy, and how it’s been used throughout history is the meat of this book.

What I like about this book: Sarah begins with how Indigenous people living near rainforests in Mexico and Central America created and used rubber. 

She explains how European explorers took rubber back with them – along with the gold and riches they stole – and how rubber became part of our lives. Sprinkled throughout are spreads labeled “The Science” where she explains bounce, polymer chains, and why pure rubber fails in heat and cold.

I also like the illustrations – they add a touch of fun to this bouncy history. And there is Back Matter! Sarah discusses names of the Indigenous people, and shares some of the troubling details about the sometimes violent history of the rubber industry and some of the environmental issues. She also includes a timeline of the last 3,500 years of rubber history.

Bouncy Science Beyond the Books: 

Compare bounciness of a variety of balls. You’ll need a hard surface for your bounce test and a way to measure height - you can tape a couple yard-sticks or tape measure against a fence, wall, or tree. Drop each kind of ball from as high as you can reach and write down how high it bounces.

Measure stretchiness of a rubber band. First, measure the width (how “fat” the rubber band is) and the loop-length (how long it is before you stretch it). Now hook one end of the rubber band over the end of a ruler and gently stretch the rubber band. How far can you go? If you’re outside, you can let go and see how far your rubber band flies. Try different rubber bands – and remember to pick them up when you’re finished.

Make your own rubber from plants in your yard. Caution: don’t do this if you are allergic to latex! Break open the stem of a milkweed or dandelion and collect the latex in a spoon. Cover the end of your finger with the sap, all the way to the first knuckle-bend and let the sap dry. After 10 to 15 minutes, roll the dried sap off your finger. It will make a slightly stretchy band. To make a “rubber” ball, put a half a teaspoon of sap into 1/4 cup of water and stir with a straw. Slowly add a little bit of vinegar. The acid in the vinegar will make the latex stick to the straw. Gather the latex into a ball, squeeze out the water, and give it a bounce.

Explore Outdoors ~ a very hairy snail!

 A few weeks ago I noticed an interesting snail clinging to the underside of a red lettuce leaf. Interesting because usually I only find slugs in my garden ... and also because this snail had a hairy shell!

 

 "Is there such a thing as a hairy snail?" I asked my friend and snail expert, Marla Coppolino. 

"Yes," she said. "It's called the hairy snail." Unfortunately it is not native to our area.

I watched it for a bit and here's what I learned: a snail's pace isn't as slow as we think. At least not for this snail. It speedily moved up the leaf, searching for a tender spot to begin scraping away with its sharp, spiny mouthparts.

What sort of snails have you seen?

Books to Celebrate Dinosaur Month

 October is National Dinosaur Month and I’ve got three great books that are perfect for young paleontologists!

Themes: dinosaurs, nonfiction, biography

Dinosaurs Can Be Small 

by Darrin Lunde; illus. by Ariel Landy 

32 pages; ages 3-7

Charlesbridge, 2024

 A Brontosaurus raises its head above a ginkgo tree. It is a long-necked dinosaur. But not all long-necked dinosaurs are big.

Many dinosaurs, it turns out, were small. Some as tall as you, others no taller than a Barbie doll. And that’s okay, because sometimes smaller is better. Smaller dinos needed less food to fill their bellies. They could survive eating insects. They could climb trees. And when the large dinosaurs were wiped out by a giant meteor, it was the small dinos that survive.

What I like about this book: I like the compare and contrast structure. On one spread Darrin Lunde introduces a large dinosaur – Tyrannosaurus, Tricerotops, Pterodactyl (not really a dinosaur but a close relative). The next spread highlights a tiny dino-relative. Back matter shows each dino with an explanation about their name.

She Sells Seashells: Mary Anning, an Unlikely Paleontologist 

by Heidi E. Y. Stemple; illus. by Emily Paik 

40 pages; ages 5-9

Charlesbridge, 2024

Mary Anning was an unlikely paleontologist. Especially unlikely for England in the early 1800s.

Because she wasn’t really a paleontologist at all. She was just a girl who collected fossilized seashells to sell in her family’s seaside shop. Back then, girls could collect things – they just couldn’t study them. Girls didn’t go to school, and they certainly didn’t become scientists. But Mary did.

What I like about this book: I like how Heidi Stemple shows the patience and persistence of Mary Anning as she chipped and dug fossils and bones from cliffs and stones. I like the use of repetition of some phrases such as, “Chip! Scrape! Chip!” I particularly like how she portrays Mary: unconcerned about those “rich boys” and “educated men” because she had fossils to find, and was too busy educating herself. Back matter dives a bit deeper into Mary’s life and the fossils she discovered. Plus, we learn about another Mary who lived just 150 miles away who was also digging up fossils! (And who, like Mary Anning, never got the credit for her discoveries.)

Mary Anning and Paleontology for Kids: Her Life and Discoveries, with 21 Activities 

by Stephanie Bearce 

134 pages; ages 8-12

‎Chicago Review Press, 2024

It is only fitting that Stephanie Bearce, a fossil-collecting, award-winning author, write about a girl who loved fossils. She begins with Mary Anning’s early life, fossil-hunting with her father, to Mary’s discovery of her first skeleton. Stephanie shows hoe Mary painstakingly removed the fossilized bones from the shale and how those bones, bought by a wealthy man, wound up in a museum. Mary did more than dig up bones, though. She cleaned them, figured out how to put them together in a complete skeleton, and creates detailed scientific illustrations about her finds. 

What I like about this book: Scattered throughout the book are sidebars that dive into details about aspects of life in the 1800s as well as the hands-on activities. Young readers can try their hand at making a fossil imprint, creating their own scientific illustration, and doing their own fossil extraction. I especially like that there’s an entire chapter devoted to female fossil finders and one on modern paleontology. 

Beyond the Books:

Make some dinosaur footprint cookies. You’ll need a plastic dinosaur or two… here’s the recipe.

Make a paper bag dinosaur puppet. All you need is a paper lunch bag, some construction paper, scissors, glue, and imagination. But here’s how one person made their puppets.

What kind of dinosaur are you? Gentle giant or fierce meat-eater? Here’s a quiz from the London Museum of Natural History that will reveal your true dino-heart.

Check out TrowelBlazers, a site that highlights the contributions of women in the ‘digging’ sciences: archaeology, geology, and palaeontology.
