NSTA

I spent the past several days at the National Science Teachers Convention at the Boston Convention Center.  Thursday started out with a talk by some lady from Texas Instruments.

I couldn’t figure out why she was so popular, but the next guy I am a big fan of since I started teaching!  Bill Nye the Science Guy!

He looked a bit older than I remember him when I started teaching. He talked about Dancing with the Stars and his debate with Kevin Ham.  Most of his talk centered on how to avoid getting hit by an asteroid and the end of humanity as we know it.  An interesting quote he had:

Article 1, Section 8, Clause 8

To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;

On Friday I received my big award!  Many Thanks to David and Christine Vernier for generously sponsoring the technology award.

I also met Valerie Frizzle from Walkerville Elementary School  at the awards ceremony.  She was pretty upset because the Boston Parking Authority had just impounded her school bus.

On Saturday I had a lot of fun in the exhibit hall.  This strange lizard kept telling me he could save me a lot of money if I just gave him 15 minutes of my time.  Alejandro and Leonardo liked him

Then we met a giant bunny wabbit.   We posed for a picture with him.  But I could’ve sworn I saw a putty tat.

RabbitDow chemical had a very cool robot.

Another Award!!! Not the same!

This time I won the Vernier Engineering Contest!  Yes, the same company, but a different award, and for something completely different!  Last month I won the NSTA Vernier Technology Award.  For this contest I had to create a video showing how to use Vernier probes in an engineering class. You can view my winning entry here.

This is a video from my engineering class I taught last semester at BUA.  Many thanks to Liam C. for shooting a lot of the video of the engine testing.  50 points for Gryffindor House!!!

I should also thank Mark Greenman who gave me the idea for this rocket engine test stand almost 20 years ago.  I attended an AAPT Regional in Long Island back in 1995.

 

NSTA Vernier Award

I received the following note today!

Congratulations!  You have been selected by the NSTA (National Science Teachers Association) Awards and Recognitions Committee as a recipient for the 2014 Vernier Technology Award. They reviewed many applications and yours was chosen as it showcased your exemplary science teaching skills.

The Vernier Technology Awards will recognize and reward the innovative use of data-collection technology using a computer, graphing calculator, or other handheld in the science classroom. A total of seven $5,500 awards will be presented:

One award at the Elementary Level (Grades K-5)
Two awards at the Middle School Level (Grades 6-8)
Three awards at the High School Level (Grades 9-12)
One award at the College Level

So this is pretty exciting.  NSTA is in Boston this year, so that will make traveling to the event a bit easier!

Here is the abstract for the lengthy application:

 

As a teacher I continue to learn and always display my passion for learning on center stage.  Although no longer a “student” in the traditional sense, I am engaged in research in science and engineering.  I am also involved in educational research.   As teachers we need to listen to what students are saying.  We need to try to understand what they are thinking, and to track the evolution of their thought processes. Every student learns differently, and by engaging in collaborative joint-sense making, we can make the learning experience a passionate experience for every child.  I employ an active learning environment where students collaborate to explore ideas, design solutions to problems, and share results.  Through my work at the Center for Engineering and Education Outreach at Tufts University, I am part of a team developing a software platform, called InterLACE, to aid students in collaborative inquiry based learning.  Students share their ideas through this cloud-based platform and then engage in class discussions.  My role as teacher is to moderate and steer learning

For my activity, students develop a model for the pendulum, a traditional high school physics experiment.   My activity is different because of the required use of collaboration and use of a wide variety of Vernier sensors, including photogates, Motion Sensors, accelerometers and image analysis.  Students also analyze data I gathered with a Vernier Wireless Dynamics System Sensor that I flew in an experiment on a NASA Reduced Gravity Flight.

Sparks

Recently in physics class we just finished out unit on electrostatic.

Many thanks to Eric for providing this nice vide

 

 

After our introduction to sparks we played with the Van DeGraf Generator, which builds up a huge amount of charge, and makes you into an electroscope as we can see in these photos!

Adorable girl and adorable robot

I had to post this picture.  One of the youngest people to buy my book sent me a picture of herself with the LEGO Mindstorm robot she made.

Makerspace and bringing artwork and manufacturing back to the US

When working at Tufts I was able to start playing around with 3D Printers.  3D Printing allows us as individuals to create physical objects that we can imagine!

Boston University just opened a giant facility which we might call a “Makerspace.”  But that is an understatement.  EPIC is the new manufacturing training center for Boston University.  There are rows of 3D Printers, Laser Cutters, Milling Machines, and Lathes.

On a personal level, my wife just moved her art studio up from the basement and into our dining room.  Maybe that is a hint I need to move the trains, robots, and tools out of the way.   She is following her passion and creating wonderful artwork that she is trying to sell on Etsy.  You can view her stuff online here:   Www.etsy.com/shop/Horizontecreativo

The wonderful thing about the digital age is that it is allowing up to be “Makers” and “Creators” as opposed to all of us having the same objects we buy at Pier One Imports but are all imported from a factory in the far East.   I seem to remember this was the theme of an episode of Friends or Seinfeld or some 90′s sitcom.

Here are some of the things that my wife has been busy making recently.

Science of the Olympics

As the Olympics are starting, a friend pointed out this great web-site.
http://www.nsf.gov/news/special_reports/winterolympics/

Speaking of the Olympics, I just spent some time tonight organizing the New England Physics Olympiad.  So if your school is interested, we will soon have information on a date and a location for this annual event.  This year we are planning to integrate it with the AAPT Physics Bowl.

Next week, we will be proctoring tests for students trying out for the US Physics Team.  Next Wednesday, Jan 29th, after school.  If you want to try out, take some practice tests, and you will need to sign up in Web Assign.

 

 

Robot Season off and Running

So it has been a busy week in the lab.  After cleaning up after our VEX Tournament on Sunday, the students have been busy building our FRC robot!  They have been busy prototyping a few different ideas.  You can read the updates here.

One of our alums, who was a freshman when during the first year I ran the robotics team almost about 13 years ago, Sam Duffley, finished building his robot as part of the Robot In 3 Days competition.

So check out the videos.  These are FIRST alums who decided to see if they could build a robot in 72 hours.  He is part of Team Boom Done, which is the iRobot team.

You can watch their team here.

Projectiles and Winter Break recharge

The end of the semester was busy hosting a FIRST LEGO League tournament but things are finally now back up to  speed.

We finished the semester studying projectiles and satellites.  One famous physics demonstration in the study of projectiles is the Hunter Monkey demonstration.  Stav produced a great slo-mo video of this demonstration I wanted to share.  The physics question is, “A hunter aims his gun at a monkey in a tree.  If they monkey lets go of the tree branch the instant it hears the gunshot, why does the projectile still hit the monkey?”

 

Momentum and an asteroid hitting the Earth

This past week we started to study momentum, and how to give an object momentum by exerting a force over a period of time, or an impulse.

One demonstration the students enjoyed was throwing eggs at a sheet.  Here we can see the students throwing an egg at a sheet, yet it is not breaking!  The sheet extends the time of impact, thus lessening the force.  Here you can see this is slow motion thanks to Stav and his iPhone.  10 points for Hufflepuff.

 

In the coming week, we will be examining collisions.  In time for Halloween, I call this lab “Creepy Crawly Carts that go BUMP in the middle of the night.”   Some carts go BUMP and stick together with Velcro.  Some carts are silent and make no noise when they collide (magnets).  Other Creepy Crawly Carts go BOOM in the middle of the night.  They ‘explode’ apart using a spring loaded plunger.  Click here to view the lesson on these Creepy Crawly Carts.

Often students (in a panic) ask m if it is okay that they have not done their homework.   I sometimes facetiously answer that the only thing that will prevent the asteroid from hitting the Earth is a completed homework assignment.  Well, the asteroids have been in the news a lot recently.

To quote Craig Robinson, director of the Copernican Observatory and Planetarium at CCSU, “Speaking of asteroids hitting the Earth one of the largest, if not the largest found so far, fragment of the meteorite that landed in Russia this past February has been found in the lake next to the city it landed in. This particular fragment looked to be about the size of a desk and is roughly roundish in shape. They tried to weigh it but the scales they tried to weigh it on broke so at the time I saw the news cast about it (This morning.) there was no idea about its weight other than it was very heavy for its size.”

Here is the CNN video on finding the piece at the bottom of the lake.

 

There was also a recent deluxe article on the asteroid on BU Today.  Just how are we going to save the Earth from the asteroid, which has a LOT of momentum?  Can we blow it up?  Or do we nudge it slightly?  Deliver an impulse with a laser beam?   If we exert a small force (laser) over a long period of time, we can still deliver a significant impulse to the asteroid.  Read what BU Professor West Jeffrey Hughes has to say on the subject.  I think if we take all the uncompleted homework assignments from BUA students over the years, put them in a rocket, and launch it at the asteroid it might provide just enough impulse to push the asteroid off course and save the world!  I should enter this idea into the NASA Grand Challenge.
