Great new kids’ science book

Spread the love

Don’t Mess With Me: The Strange Lives of Venomous Sea Creatures by Paul Erickson is part of a series that is currently small but hopefully growing by Tilbury House. I previously reviewed One Iguana Two Iguanas (about iguanas).

Like the Iguana book, Erickson’s book for third through seventh graders (8-12 or so years of age) contains real, actual, science, evolutionary theory, and facts about nature, along with great pictures. The key message is that toxins exist because they provide an evolutionary advantage to those organisms that use them. Why are venomous animals so common in watery environments? Read the book to find out.

Species mentioned includ the blue-ringed octopi, stony corals, sea jellies, stonefish, lionfish, poison-fanged blennies, stingrays, cone snails, blind remipedes, fire urchins.

Highly recommended as a STEM present this holiday season.

One Iguana Two Iguanas: Children’s evolutionary biology book, with lizards!

Spread the love

The land and marine iguanas of the Galapagos Islands are famous. Well, the marine iguanas are famous, and the land iguanas, representing the ancestral state for that clade of two species, deserve a lot of credit as well. The story of these iguanas is integral with, and parallel to, the story of the Galapagos Islands, and of course, that story is key in our understanding of and pedagogy of evolutionary biology, and Darwin’s history.

Gift Guide: Science and technology books for adults and kids

This is a short list of science books that came out over the last year that I’ve reviewed, and thought you might do well to be reminded of. Since your holiday shopping list surely includes targets with a range of demographics interests, I made this a diverse list.

Gift Guide: Books About Trump And The Fall of America

Spread the love

Might as well admit it. America has been ruined. Oh, it is fixable, not “totaled” like your car after you roll it down a hill during an ice storm. More like you failed to set the parking break and it got loose and crashed into a brick wall, then some hoodlum broke through the window and ripped out your radio, then there was a hail storm…

Anyway, here is a carefully selected list of books related to Trump and the Trump fake Presidency, integrated with a list of books that are NOT about that, but rather, leadership in history. The former are to get you steamed up, the latter, they are the control rods. A few are just about attacks on democracy from the elite and powerful.

I thought it would be fun if everybody gave at least one of these books to somebody as a holiday gift this year. I’ll be giving a few. Continue reading Gift Guide: Books About Trump And The Fall of America

Deck the halls with boughs of LEGOs!

Spread the love

You may have heard of the famous The LEGO Christmas Ornaments Book: 15 Designs to Spread Holiday Cheer. Now, there is a new edition out with all new ideas: The LEGO Christmas Ornaments Book, Volume 2: 16 Designs to Spread Holiday Cheer!!!!

The book does not come with LEGO bricks, so you’ll have to use your own, or order them. But the idea of a book like this is not to give precise instructions of what to do, but rather, theory, ideas, methods, to create your own. Continue reading Deck the halls with boughs of LEGOs!

A Beginner’s Guide to Circuits

Spread the love

Some time ago I reviewed Electronics for Kids: Play with Simple Circuits and Experiment with Electricity! by √ėyvind Nydal Dahl, which is a very good introduction to electricity and how to hvae fun with it. There is now a new book that is a somewhat simplified version by the same author, A Beginner’s Guide to Circuits: Nine Simple Projects with Lights, Sounds, and More!.

This new book is smaller, has fewer projects, requires the purchase of fewer components, is an accordingly less expensive book, and perhaps most important for some people, requires no solder! Continue reading A Beginner’s Guide to Circuits

The Solar System from The Smithsonian

Spread the love

Smithsonian Exploration Station: Solar System by Jon Richards is similar to the previously reviewed Exploration Station: The Human Body. This is part of a new series of STEM learning toys from the Smithsonian, and they are just now available for purchase.

As is the case with the other kits, the Solar System includes a book, a large format big flat thing to which one might attach stickers, stickers, and a unique on-topic object, in this case, those cool stars you can attach to your ceiling or walls, and they glow in the dark.

Build Miniature Cities with LEGO

Spread the love

LEGO Micro Cities: Build Your Own Mini Metropolis! is a LEGO building idea book that provides a macro number of examples of building buildings, or other structures using a very small number of bricks. It is like the N-guage of LEGO. This is sort of the opposite of the LEGO idea book I recently reviewed, The LEGO Architecture Idea Book, because the latter is for large scale, and the former for very tiny scale.

Author Jeff Friesen is a famous LEGO builder, and a photographer, who tweets at @jeff_works.

You get an idea of how to build skyscraper, bridges, public transit elements, and tightly packed downtown zones. There are suggestions for how to build the geology that underlies the buildings and other infrastructure. And the subways. Continue reading Build Miniature Cities with LEGO

Extending The LEGO Boost Robot Kit With A Book

Spread the love

The LEGO Boost Creative Toolbox is a humanoid robot that is also a guitar, a dogbot, and an industrial fabrication machine. Which of these things it is depends on which set of instructions you follow. A scratch-like programming language lets you control the boost from a phone or tablet, via blue tooth. It is not cheap, but it is an amazing and excellent toy.

It does take absolutely forever to build any of these projects, but there are stages along the way where you can stop and play with what you’ve got so far. Continue reading Extending The LEGO Boost Robot Kit With A Book

A Classic STEM toy: Rock Tumbler

Spread the love

National Geographic Hobby Rock Tumbler Kit is truly a gift that keeps on giving. We got one last year at Christmas time, and it has been running ever since, except in the coldest months of the year. It is noisy, so you will need to have a place where the sound is not a problem. We run it in the garage (thus the moratorium during the deep cold Minnesota Winter).

There are other rock tumblers out there, and if you want to get serious, you’ll want to shop around and maybe even look at the Vibratory Tumblers, a related technology.

Warning: Figure out a way of disposing of the sludge that does NOT involve putting it down a drain. It will ruin your drains. Dig a hole in the back yard, or make an evaporation system (that’s what we do) so you can throw the dried sludge in the trash.

Expect to buy more rocks, as well as more raw materials. Here are a few examples of what we invested in:

Polly Plastics Rock Tumbler Tumbling Media Grit Kit & Plastic Filler in Heavy Duty Resealable Bags

Crystal Allies Materials: 1lb Bulk Rough Pink Rose Quartz Crystals from Brazil – Large 1″

Crystal Allies Materials: 3 Pounds Bulk Rough 10-Stone Assorted Brazilian Mix – Large 1″
