Exploring Gears with PASTA! I dyed some pasta one night to use for some crafts. One of the kinds I had was mini wagon wheels, and when I brought them inside from drying in the garage overnight, my brain was chanting "gears!" so I grabbed some toothpicks and cardboard boxes and made a wagon wheel gear train. I had to share it with the kids (and you too)! Materials needed for gear pasta: wagon wheel pasta (dye if desired) toothpicks cardboard box Get started on this gear STEM activity Pick out the most circular ones to make this easier. All you have to do is put a wagon wheel on the cardboard box and impale the cardboard right through the center hole. Put another wheel next to it and poke your next toothpick through. Try this with a mix of mini and large wagon wheel pasta as well to make this even more fun! Here's a short video of the pasta gears in action: Engage your students by going in depth with more STEM challenges This activity was so beneficial for hands-on learning that I developed it into a STEM challenge lesson for upper elementary students. It can be found as one of the challenges in this STEM challenges resource: Pin these ideas for later:

As we continue our journey through Apologia Anatomy & Physiology, I have found lots of cool projects to keep us busy and to reinforce the lessons we are learning. From my review of Supercharged Science in Spring of 2013, I remembered seeing a lesson with this project, and thought it would align perfectly with the unit that was studying all the muscles and tendons. From this project, we learned that hands function because of the way the tendons are aligned. We found the tendon in our wrist that, when pressed, causes the fingers to twitch and curl. It is pretty amazing to study the handiwork of God and realize all that a hand is capable of performing. We went to the Supercharged Science website and watched the lesson on how to build the robotic hand: Then we gathered our supplies: Supplies include: cardboard scissors utility knife bendable straws string or yarn thick rubber bands hot glue gun and glue sticks pencil We traced an adult sized hand on cardboard and carefully cut it out: We glued the bendable straws on each finger, so that the bendy part was on the hand and the long part of the straw was on the fingers. We trimmed the edges of the straw to align with the edge of the fingers. We took our pencil and marked on the fingers of the cardboard hand the location of the joints and knuckles from the real-life hand. Then we took the utility knife and carefully scored the back side of the hand on those lines, so that the fingers would curl and bend properly. Using our pencil marks as a guide, we carefully sliced a section of the straw off (at 45 degree angles) where the joints are located. This helps the 'fingers' to bend properly as well. When we are done with all the joint cuts, it looks like this: We took string and ran it through each straw, leaving a long tail out both the top and bottom of the straw. We cut the rubber bands so that they would be a long strip instead of a circle. At the top of each finger, we tied the string and rubber band ends together in a small knot. Turning the hand over, and with fingers straightened out and laid flat, we hot glued the loose ends of the rubber band down to the back of the hand. The glue should only be right at the end of the rubber band. The rest of it needs to stay loose so that it can freely move and guide the fingers. The rubber bands help the fingers to return to their natural state after being curled up.  Once the hand was completed, we had lots of opportunity to 'play' with it and see how the tendons in a hand function, by pulling downward on the strings.  One of the favorite things to do with the hand was to make sign language letters and spell out words and phrases....or to say "I love you"! This was a great project and we were very happy with the outcome. Everyone who has seen it is fascinated by it, and it clearly demonstrates the movements of a hand. I highly recommend this project!

This photograph shows the U-Boat 110, a German Submarine that was sunk and risen in 1918. This photograph shows the control room in the Submarine, including the manhole to the periscope well, hand wheels for pressure gear, valve wheels for flooding and blowing and the air pressure gauges. Reference: DS.SWH/5/3/2/14/1/26 This image is taken from an album of photographs found in the Swan Hunter shipbuilders collection at Tyne & Wear Archives. The album is from 1918 and documents the U.B. 110 before she was scrapped on the dry docks of Swan Hunter Wigham Richardson Ltd, Wallsend. The twin-screw German submarine U.B. 110 was built by Blohm & Voss, Hamburg. On the 19th July 1918, when attacking a convoy of merchant ships near Hartlepool, she herself was attacked by H.M. Motor-Launch No. 263 and suffered from depth charges. Coming to the surface she was rammed by H.M.S. Garry, a torpedo boat destroyer, and sunk. In September she was salvaged and placed in the admiralty dock off Jarrow slake. She was then berthed at Swan Hunter's dry docks department with an order to restore her as a fighting unit. The Armistice on 11th November 1918 caused work on her to be stopped. She was towed on the 19th December 1918 from Wallsend to the Northumberland Dock at Howdon and was subsequently sold as scrap. The album of photographs, taken by Frank & Sons of South Shields, documents the U.B. 110 in extensive detail. The photographs provide a rare glimpse into the mechanics and atmosphere of the raised German submarine. More images of the U-Boat 110 can be viewed here.

Remember when Segways came out and everyone was blown away by the leaning controls and the idea of a personal electric vehicle? Or, do you only remember the fact that everyone looks stupid riding them? What if you could use the same sort of concept, but make it not suck? Onewheel is kind of like

Will we ever give up our beloved gas-guzzlers for leaner, greener electric cars? It might be a long road - so to speak - to alternative powered cars, but it seems like electric cars are gaining favor all over the world. This is evidenced by the sheer number of electric car designs that pop up

I wrote a little generator to create these type gear wheels. They actually work, though cardboard is probably not the ideal material for these delicate shapes. Since the cardboard was a bit too weak I made a motor driven version from wood: www.youtube.com/watch?v=XUdE0e_zdRo
