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.
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.

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.
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!→
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→
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. Continue reading The Solar System from The Smithsonian→
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→
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.
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:
There is a new series of educational kits called Exploration Station, coming out in a few day. You can pre-order them. I’ll post about three of them, starting with Exploration Station: The Human Body.
The kids are designed for learning by kids six years and above, but I think they are ideal for third or fourth graders. All the kids follow a similar theme. There is one item that will end up on a bedroom shelf along with other toys like items. In this case, a make it yourself human skeleton one foot tall. There is a book on the subject, in this case, the human body. There is a large sheet of heavy duty laminated material and a set of stickers to stick on to it. In this case, it is a 13 by 18 inch poster with a depiction of the human body. In addition, this kit includes a set of flash cards about various aspects of the human body or physiology.
The science is good, the book is engaging, lots of words but also lots of pictures. The manipulable materials are fun and educational.
I think the kits were originally designated to be about $22, but the pre-order price is closer to $15 . I think they are worth the larger price, but the lower price is very nice.
This is an ideal holiday gift for a kid in the right age range. It is not going to fill your space with a pile of useless crap, and it is not going to make a mess, or any noise. The educational value is high, and the quality is right in the range for an item of this price range. The only down side is that it is a little hard to wrap round things, but you’ll mange.
