Physics & Physical Science Demos, Labs, & Projects for High School Teachers

Posts Tagged ‘CAD

Last year, the course was actually called Robotics and Astronomy, or Robostronomy for short.  The intent was half-year of each.  The result was more like three weeks of astronomy and robotics all year-long.  Don’t get me wrong, I love astronomy.  It’s just, well, Robots took over the Earth.  Between the great things we could do with the MindStorm, and then the SeaPerch competition, we were all robots, all the time.  This year we are adding the First Tech Challenge.  Yep, Robots have taken over the Earth, and it looks like they landed in my classroom.

The goal here is STEM, that’s what opened the door for the robot invasion in the first place.  Clearly missing from our program these days is what we called in the old days, ‘drafting.’  Drafting isn’t done on a board with a T-square anymore, but you all know that.  Today, 3D mechanical Computer Aided Design (CAD) is available for free from Google (Sketch-up), and from a number of companies who cater to the high-end.  I actually know this industry well, I spent 25 years in the CAD/CAM/CAE industry (M for manufacturing, E for Engineering, meaning simulation).

So with some guidance from some friends at Drexel University, and a little research on my own, I decide to go with SolidWorks software.  All of the vendors have aggressively priced programs for the educational market, I think we are paying just $1000 for a 10-seat license.  What makes this software connect to the students is what we spit out of it.  The school invested in a 3D printer, specifically uPrint Plus from Dimension.

If you have never seen one of these, think Star Trek Replicator.  The replicator creates parts from ABS+ plastic directly from the output of the 3D CAD.  How better to teach engineering principles than to give the students a design challenge, have them work through designs and then fabricate it in the printer.  Here is a great video from a customer talking about how they use a 3D printer in their engineering design work.

My new printer is due here any day and I’m pumped up.  Yep, geek boy has a new toy.  Tea, Earl Grey, Hot!


What’s New in 2013/2014?

Every year brings a change, this one is no exception.

I will be picking up the sophomore honors Algebra II class to keep them separate from the juniors. This should help accelerate them and put them on a stronger track towards Calculus. Looks like there will be only one section each of Physics and Calculus, but still two of Robotics & Engineering.

Hot topics this year are going to be the Common-Core Standards, Standards-Based Grading (SBG), improving AP Calculus scores, and somehow adding Python, maybe as a club.

Just a quick poll to help me understand who is stopping by my blog.

Yeah sure, lots from America, but look who else is here…

If you are badly in need of more email or for some reason jonesing for a physics fix, enter your email address so I can bother you with my newest rant on science.
