Seed of the Week: Clematis

As Craig guessed, our golf-club-shaped seeds from last week were from a clematis.

deep-red-clematis-vineWhen you think of clematis, you likely think of the vine with the big, brightly-colored flowers.

Our seeds came from a clematis that is a little different.

What kind of clematis do you grow?  Have you ever seen the seeds?

A New List of Chemistry Books for Kids

Does it seen like this blog has been a little quiet lately? Wondering why?

Well, for the summer I have some obligations that will keep me otherwise occupied. These obligations involve teaching a high school chemistry class, among other things. In preparing for the class, I’ve found some chemistry books that might appeal to chemists and non-chemists alike. Some of them are for kids and some are for young adults. Let’s start with one for kids this week.

Why Is Milk White?: & 200 Other Curious Chemistry Questions by Alexa Coelho and Simon Quellen Field

In this unique project, 11-year-old Alexa Coelho came up with the questions and science writer Simon Field answered them. What better way to ensure that the information included is age appropriate than have it originate with a child?

Coelho asks questions like, “Why do onions make you cry?” “Why does sugar cause cavities?” and “What causes bad breath?” To his credit, Field takes every question seriously and fully answers each one as clearly as possible. He also includes some age-appropriate experiments to try at home, from lifting latent fingerprints from a “crime scene” using super glue (for smooth surfaces) or iodine (for paper) to hollowing out the zinc interior of a penny using muriatic acid. 

Not everyone will need to read this book cover to cover. Readers can skim and skip to questions that intrigue them. Those fascinated by chemistry and how the world works, however, won’t be able to put Why is Milk White? down.

Bug of the Week: Tumbling Flower Beetles

Have you ever spotted a beetle and haven’t been able to figure out what kind it is?

Tumbling flower beetle-11Take these black insects, for example. You might not even be sure that they are beetles.

tumbling-flower-beetles-22Fortunately, I was able to key them out using a new book (see below for details). These are tumbling flower beetles, in the Family Mordellidae.

flower-beetle-closeTumbling flower beetles are distinguished by their wedge shape and the fact their elytra (hard wings) do not cover the abdomen.The abdomen is pointed at the end, as well.

They are called “tumbling” because the adults have an odd behavior of awkwardly jumping away from predators that leads them to tumble. The “flower'” part comes from the fact the adults are often seen at flowers feeding on nectar.

Have you ever seen tumbling flower beetles tumble? How would you describe it?

_____________________________________________

The book I used to identify the insects is Beetles of Eastern North America by Arthur V. Evans, just published this month.

This book is an extensive desk-top reference for those interested in beetles. Along with the illustrated key to common beetle families, it contains detailed descriptions of 1,406 different species of beetles, each accompanied by a good sized full-color photograph.

In addition to helping with identification, Beetles of Eastern North America is also a fabulous place to start learning about beetles in general. There is an extensive introduction covering anatomy, natural history, where to look for beetles, how to observe and collect them, etc. It is filled with information, even the end paper in the back has a ruler and illustrations of beetles with their parts labelled.

Are you interested in working with beetles? On page 52, Evans discusses how to become involved in beetle research, encouraging students and amateur naturalists to participate in citizen science.

Examples of beetle-related citizen science projects:

Beetles of Eastern North America definitely is worth consideration if you have ever wondered, “What is that beetle?”
