IME Activities: Cost Management  April 9th, 2015

This is another great activity made for us by our IME Team.  In this activity, students will use LEGOs to design the most cost effective airplane without compromising on function. See the links below to run this activity in your classroom:

IME Activities: Optimization Methods  April 8th, 2015

This year, like previous years, our IME Team has made several lesson plans to share. This Optimization Methods Activity focuses on the most efficient path to travel, much like engineers do. Below are the materials to run this exciting activity.

New Grand Engineering Challenge: Food Waste  March 4th, 2015

Food shortage is not the only issue anymore.  Wasting food is having a dramatic effect on the environment, economy and society. An estimated \$162 billion is being lost because of unused food, as seen in this New York Times article.  This is an interesting topic to pose to your students. What solutions can you come up with to solve the food waste problem in your club, school, community, state, country or world? How does this solution work? Share with us!

3D Printing  February 27th, 2015

In our most recent post, the ME team used a 3D printer for one of their parts. What is 3D printing? There are different ways to print three dimensional objects, which are detailed in this link. Our ME team used the fused deposition process for their part which can be seen below. These printers are not only used for small parts and projects, they are also used to make everything from medical supplies to an entire car (see below).  Companies like Protolabs and Solid Concepts specialize in making molds and parts. These links will help your students understand the things mentioned in the previous ME video. For the future, the hope is that 3D printers will make manufacturing of tools and products faster without compromising on strength and durability. Check it out!

Update from the ME Team  February 27th, 2015

The ME team is at it again.  This time they hit some roadblocks while making their three modules.  The team was able to persevere and their project is nearly complete. Check out the progress and process:

Magnetic Silly Putty Eats Magnet  February 23rd, 2015

Amazing right? But how does it work? In a basic sense, the magnetized putty is trying to evenly distribute itself around the magnet.  This article explains it all. You may want to share this with your students!

Happy Birthday Galileo!  February 17th, 2015

That’s right, Galileo would have been 451 years old today. To celebrate his birthday we thought it would be great to share this article proving his theory true; a heavy item and a light item would reach the ground at the same time in a vacuum. In the video below, they travel to NASA’s space power facility in Cleveland, Ohio to the worlds largest vacuum chamber to prove his point.

Update: ME team  February 17th, 2015

The team has expanded upon their awesome project.  This week they expanded on their crank.  Here is what they had to say about it:

Building on our previous design, we machined an acrylic sheet into an acrylic disc to mount on the generator for easier use (video 1). We then kept building the power generation module so that we could test our other equipment better (photo 1). We disassembled part of the TV to try and test it with our generator, but weren’t generating enough power or had some other issue (photo 2). We managed to cut all of our acrylic for the hydro power module and we tested flame polishing on one of the pieces (photo 3, 4 and video 2). The video game has been further tested and we can successfully use other buttons to play the game! (Although Pac-Man is still really hard) (photo 5). Finally, we made some welding modifications to the base of the generator to make it simpler and more sturdy (video 3). Next, we’ll be building the structures of the modules and finally have something to really show off!
