Amazing Mouse Video

Last year members of our 4-H club designed simple mazes and let our pet mice try them out. Because of that past experience, we were totally in awe and inspired when we saw this mouse in action.

I have two comments. First, this is a special mouse. We found each of our mice had distinct personalities. For example, our present mouse, Squiggle, would be way too shy to do this. We did have a mouse named Spot, however, who would have loved to have this sort of stimulation.

Second, note the black dots about the course. I suspect the mouse has left droppings because it has run the course before. Mice have a keen sense of smell, and by leaving the droppings it was probably able to get cues from them. I know wild mice have been shown to create piles of debris to act as trail markers.

Check our post on pet mice for more information about activities you can do with a pet mouse.

Thanks to our friends, the Millers, for pointing out this amazing mouse video!

Science Poetry

If you are looking for some books that aren’t the usual fare, why not try some science/nature themed poetry? Here are a few that deserve to be a part of every home library.

If Not for the Cat by Jack Prelutsky and Ted Rand (Illustrator)

A friend of mine recently showed me this book, written all in haiku. Although that might sound about as exciting as bread molding, this is an incredible book. The vocabulary is stimulating, and the illustrations are superb. I would say this book would be acceptable as a read aloud for younger children and definitely would be a book your children would return to again and again. Although the cat is the title, most of the poems involve creatures from nature.

insectlopedia by Douglas Florian

My son’s first grade teacher gave a copy of this book to my son and he still cherishes it. I love the fact it is accurate and insightful, as well as creatively fun. And yes, the title is supposed to be in lower case.

mammalabilia by Douglas Florian

Douglas Florian actually has a whole series of poetry books, so if your child isn’t interested in insects, try some of the others.

in the swim by Douglas Florian

The Amazon.com review of this book says: “Even the most educated marine biologist could learn something from this whimsical, beautifully illustrated collection of 21 poems about sea life.”

Math Talk: Mathematical Ideas in Poems for Two Voices by Theoni Pappas

Although not a science book, per se, if you like poems for two voices, this is another fun one.

Poetry Matters: Writing a Poem from the Inside Out by Ralph Fletcher

This book is a great resource for older children (and even adults) who are interested in writing poetry. If every school used this book to teach poetry, I am positive that poetry would be everyone’s favorite subject.

Finally, if you want to learn more about nature/science poetry, try The Miss Rumphius Effect website.

Hope you enjoy some poetry today!

Bug of the Week: Ants Visiting Extrafloral Nectaries

It is cold (for us) and windy this morning, and I wasn’t sure I’d be able to find a bug of the week. No fear, there’s always something going on in the insect world.

barrel cactus

First I checked our barrel cactus, which is covered with yellow fruit.

As I got closer, I spotted a beige patch near the base of one of the fruit towards the right/center of the photograph. You’ll be able to see it more clearly in the next photograph.

The biege patch looked soft and furry, with some yellow and orangish bumps.

Ants were visiting those bumps in a purposeful way. First they would arrive looking slender.

After spending some time with their heads near the bumps their hind portion, called a gaster in ants, would start to swell up.

These ants are feeding at the extrafloral nectaries of the cactus. Nectaries are parts of a plant that produce the sweet juicy nectar. Many are found inside the flower of the plant. These structures are called extrafloral because they are outside of the flower.

Why does a cactus supply liquid sweets in the form of nectar to ants, especially in the desert where water is in short supply? There are several theories, including that ants increase the fertility of the soil around their mounds and ants are more likely to nest nearby when food is available, and/or that ants feed on insect pests while on the cactus. In any case, it is a fascinating example of just one of the complex relationships between ants and plants.

Thinking of sweets makes me want to have a cup of hot chocolate…
