Workouts for the Brain

Game nights are a great way for families to spend quality time together. But every once in a while, you need to shake things up a little, right? Here are three wonderful, mind-expanding activities that mom, dad, 2.5 kids (but not the dog) will enjoy.

Brain Benders puzzlesBrain Bender cubeBrain Benders (Alex Brands)
Brain Benders offer puzzle lovers a very different experience—visually, physical, and intellectually. Brain Benders pieces are made of wood (instead of flat cardboard), and you’ll use them to assemble a sphere, two different cubes, and double-pyramid shape. Besides patience and ingenuity, you’ll need some pretty well-developed spatial- and logical-thinking skills. Don’t have them? No problem. You’ll develop them pretty quickly. Having four puzzles makes it easy for families to spend time together—and compete against each other or the clock. One warning: Even though there are illustrated instructions for how to solve each puzzle, the pieces from three of the puzzles are very similar—and aren’t interchangeable. We put dots on the bottoms to help us keep the pieces organized by puzzle (one dot on all the pieces of one puzzle, two dots on another). For ages 8 and up. Available your favorite retailer for $9-$15 or at www.alexbrands.com

elements 4d blocksElements 4D (DAQRI)
Elements 4D consists of six beautifully designed, white blocks. Each face (a total of 36) is dedicated to a single element from the Periodic Table of Elements (remember that from High School?). Beside the name, there’s the symbol (O for oxygen, H for hydrogen, and so on) and the atomic number (how many protons in one atom of the element). But when you view them through a smartphone or device running the free, augmented-reality app, those blocks go from nice-to-look-at to amazing (or, as my middle schooler put it, “coooooool”). You get a more information and a virtual representation of the element. But wait, there’s more! Put two blocks next to each other, and you’ll see the chemical reaction and the resulting compound. For example, oxygen and hydrogen are both gasses, but together they become water. Similarly, combine sodium (actually a metal) with chlorine (a gas) and you get salt. These visuals upgraded “cool” to “awwwwwwesooooome.” Overall, Elements 4D is a fantastic way to introduce or develop an interest in chemistry and it’s an engaging resource for home or school. There are several small issues. First, the actual blocks are hard to find in stores. But if you go to the manufacturer’s website, you can print out paper versions, which still work with the app. Second, the app is available only on Google Play and iTunes, which leaves out those of us who primarily use Windows phones. Third, only 36 of 118 elements are included. But that could actually be a good thing, driving an interested child to want to learn more. http://daqri.com/elements4D-mobile/

tanglecard instructionstangle cards finishedTangle Cards (Zentangle)
After a long day putting together complex wooden puzzles and experimenting with virtual chemical reactions, your brain could use a break. And Tangle Cards (also called Yoga for Your Brain) are just the ticket. Based on the Zentangle books by Sandy Steen Bartholomew, Tangle Cards guide you through the calming, creativity-stimulating process of drawing beautiful designs. Start with simple lines and curves and gradually add more and more detail. The books have more detailed instructions than the cards and include photos of Bartholomew’s inspiration. But the cards are more portable—and just as meditative. A great parent-child(ren) activity and a smartphone-free way to keep kids occupied. For ages 5 and up. Books cost around $12, cards around $10. http://www.zentangle.com/

The Science of Building

littleBits
little bits1When you first open a littleBits kit, you might think you were looking at a box of random electronic components that you might find at a flea market. There’s a bit of truth there—you are getting a collection of components—but there’s more to it than that. Each set includes LED lights, servos, battery or power blocks, and various sensors. The object is to build something that does something, and that’s exactly what you and the kids will be able to do. The instruction book does as great job of explaining how things work, but littleBits is all about hands-on learning. String the pieces together along with materials of your own to make everything from simple on/off circuits and back massagers to moving vehicles and musical instruments. Need a little inspiration? The website has plenty of suggestion for all skill levels. littleBits is as fantastic way to introduce the kids (and yourself) to basic and not-so-basic electronics. Yes, you’re dealing with electricity, but there’s no danger of anyone getting hurt. The pieces fit together only in ways that make electrocution pretty much impossible. Perhaps the best part is watching your child think through problems, going from “what I want to happen” to “hey, I can make that happen!” For ages 5 and up. $99 to $199. http://littlebits.cc/

Air-Stream Machines
airstreamAir-Stream machines are to air what littleBits is to electronics. These engaging, fun—and, yes, educational—kits tech kids (and their parents) about air pressure and air-driven mechanics. The kit comes with everything you need to complete 10 different projects, each of which highlights a real-world application that convert air flow to electrical or mechanical energy. There are propeller-driven vehicles and batting machines that toss balls in the air. But the star of the show is a hovercraft that can actually float over land or water. Really. The accompanying booklet is both instruction manual and educational text. Air-Stream machines are perfect for anyone 8 and up who’s got an interest in science or green technology. From Thames & Kosmos (http://www.thamesandkosmos.com) or your favorite retailer for about $63.00.

Edutech Throttle Motorcycle
The Throttle Motorcycle is part of a line of toys that’s designed to show kids the inner workings of various vehicles in an interactive way. The motorcycle is already assembled, but the outer shell is transparent so kids can see how 10 separate parts of the bike function, including brakes, exhaust, engine, transmission, and turn signals. The included storybook, which you’ll enjoy reading to your little one, explains each of those functions and then gives the child a code to activate that specific system. The code is entered by pushing a combination of simple buttons (circle, square, triangle, and X) on the bike itself. Because it’s so solidly built and there aren’t any tiny swallowable pieces, the Throttle is great for kids as young as three. Batteries are required and the bike can get a little noisy with all the revving, but there’s a parent-friendly volume control that will undoubtedly come in handy. http://worxtoys.com/

Candy Chemistry
candy chemistryYou and your kids can learn the science of cooking while creating real, edible (and quite tasty) candies and chocolates at home. You’ll learn why sugar crystallizes, and about heat and the phases of matter by molding chocolates and using the candy thermometer. Your child can learn about measurements and conversions, volumes, and weights, and then eat the conclusions. The kit includes metal molds, thermometer, spatula, dipping fork, foil, paper cups, sticks, wrappers and a nice manual, but you’ll need to supply the ingredients. Parental supervision definitely required. $38. http://www.thamesandkosmos.com/
