Building with Bamboo: 13 Super Sustainable Structures - WebEcoist It’s 100% natural, thrives in diverse climates, grows up to a whopping 39 inches per day and is super-strong; why isn’t bamboo already used more often as a building material? While bamboo structures have long been common in Asia and the South Pacific, they’re only just gaining prominence in the rest of the world. From schools to disaster shelters, these 13 bamboo buildings prove just how strong, durable, eco-friendly and visually pleasing this perennial evergreen grass can be.

Johnnie's Math Page - The Best Math for Kids and their Teachers -Hundreds of Interactive Math Tools, Math Activities, and Math Games Johnnie's Math Page is the site to find fun math for kids, math games, and even a little math homework help. Interactive math activities from across the web have been organized by topic to make math learning enjoyable and interesting. These activities have been chosen to represent the range of math learned from kindergarten to middle school. I have put together resources for middle school math. In the middle school math section you will find fantastic models for all kinds of algebra- from linear equations to quadratics.

Kids science: Electricity 102 Science >> Physics for Kids Important things to know about electricity? Conductors and insulators - Conductors are materials that allow electricity to flow easily. Most types of metal are good conductors, which is why we use metal for electrical wire. Copper is a good conductor and isn't too expensive, so it's used a lot for the wiring in homes today. Insulators are the opposite of conductors. The Fine Art of Electronics {under construction} This tutorial shows you how to make a paper battery holder for coin cell batteries (CR2032 and CR2016).

Thunderbolt Kids If we want to keep a record of how we constructed a specific electric circuit, we can take a photo of it. If we do not have a camera, we can remember the circuit by drawing a sketch. Look at the sketch below which Farrah drew of the circuit that you made in the activity with the paperclip switch. That's right Jojo. That Thing There: Paper Circuit Projects from Maker Faire Detroit 2013 These are the "card" projects that I had at Maker Faire Detroit. I'm dividing the projects in two or three posts because I want to show the circuit paths both with and without notes and I didn't want the length of the post to get too unwieldy. Two quick notes: I took these pictures after Maker Faire and after they were abused examined many times over so they may look a little tired but that's because they are.

Bristlebot: A tiny directional vibrobot The BristleBot is a simple and tiny robot with an agenda. The ingredients? One toothbrush, a battery, and a pager motor. The result? bristlebots The Evil Mad Science Auxiliary is a public group on Flickr for anyone to add photos that are (at least marginally) related to posts and projects from Evil Mad Scientist Laboratories. Lately some fantastic photos and projects have shown up in the group, so we thought that we should stop and round up a few– not all– of the great things that we’ve seen there. The photos below were taken by their respective owners; click on the individual photos to get the full story. A dark detector built by cyenobite, using a tiny battery holder. Beautiful Joule Thief light by Jimmie Rodgers Adam Greig has been having fun with AlphaPOV.

Bristlebot racing snail Those mad hatters over at Evil Mad Scientist Labs have been at it again. After Windell wowed us with his simple but surprisingly motile “Bristlebot,” Lenore has taken it in a whole different direction with a snail plushie that moves by the directional motion of its velvet fibers. A Velvet Bristlebot Racing Snail – Link Related: HOW TO – Make a Bristlebot a tiny directional vibrobot made from a toothbrush! – Link Science Party: Fiber Optic Lamp What's a Science Party without Physics, right? To balance out all those other Chemistry experiments, Emily and I decided it would be fun to do a little electric circuitry. We also wanted to stage a fake dissection as a token Biology offering, but fabric frog innards were too time-consuming to sew, so we filed away that idea into the Maybe Another Party category of my brain.

Science Party: Bubble Slime Here is Slime #2: Bubble Slime. A different recipe than the Regular Borax Slime, but this one again has just two ingredients: liquid starch (we bought ours at Walmart for about $2) and glue. Like regular slime, you can use either clear or white glue. This slime was a little more tricky to get right; you'd be able to blow a bubble regardless, but too much starch would make it too plasticky to support the bubble long enough to enjoy it and too much glue would make the slime too sticky and soft to handle.Here are our proportions:1/2 cup of clear glueAbout 2/3 cup of liquid starch (straight from the jug) Embellish the clear glue before adding any starch - we used glitter Engineering a Bridge This lesson will involve your students in geometry and measurement as they work as civil engineers to design and build their own bridge. OBJECTIVE Students will be able to: Identify how geometry affects bridge design and function and apply that knowledge to the design and construction of a bridge.
