• ## See Energy Transformation with a thermal camera or steel spheres [W/Video]

Posted on November 5, 2014 by Dr. David Kagan

Check out how MLB can use a thermal energy camera to determine whether a hit ball is foul or live. Then watch Dr. Baseball use the more budget friendly colliding steel spheres to create some thermal energy of his own.

• ## Help Students Reach the Ultimate Form Of Scientific Inquiry

Posted on September 11, 2014 by Dr. Joel Bryan

The ultimate form of scientific inquiry occurs when students can develop their own questions and then design the data collection experiments to find the answers. Read how this group of young science students did just that.

• ## Measuring the Acceleration with the g Ball

Posted on March 17, 2014 by Dr. David Kagan

Galileo claimed that all objects fall toward Earth with the same acceleration. Modern measurements indicate that this acceleration is about 9.8m/s2.  Using the G-Ball by Arbor Scientific, you can measure this value and compare the acceleration of other objects with different masses and in different states of motion.

• ## A Visit to Isaac Newton's Home [W/Video]

Posted on October 31, 2013 by James Lincoln

When I visited England this summer, I had the opportunity to walk in Isaac Newton's footsteps at his birthplace, Woolsthorpe Manor.

It is a little tourist museum far from the major train stops. You will probably have to take a long taxi ride from the train station at Grantham, but it’s not so far from London [...]

• ## SpillNot: The Physics Behind the Slosh [W/Video]

Posted on April 26, 2013 by James Lincoln

Although the problem of why coffee spills might seem trivial, it actually brings together a variety of fundamental scientific issues. These include fluid mechanics, the stability of fluid surfaces, and interactions between fluids and structures (we’ll set aside the biology of walking for now). The SpillNot is a cool tool for getting your students interested in the everyday physics behind why drinks spill while we’re carrying them and what has to happen to prevent spillage.

• ## Can the Frictional Force Between Two Interleaved Phone Books Lift A Car? [W/Video]

Posted on February 22, 2013 by Arbor Scientific

Students often underestimate the force of friction despite friction stopping their school buses and cars everyday. In this video 2 phone books are interwoven page by page and the friction between these thin peaces of paper are put to the ultimate test.

• ## Playing in Galileo's Lab (part 1)

Posted on October 2, 2012 by Buzz Putnam

It was 8:45 AM in Florence and I was waiting for one of the highlights of my 2012 Italian family vacation the chance to see the original creations for one of the greatest minds of the 17th century, Galileo. Take a tour of the Galileo Museum with me and see the classic Physics demos as they were in the 1600's.

• ## Energy is Energy is Energy...

Posted on February 22, 2012 by Buzz Putnam

Think back to when you were a little kid playing one of your most enjoyable family games on Saturday night. It involved rolling a die and moving around a game board, all while building a complex “mousetrap”, hoping that you wouldn’t get caught in its devious shenanigans or secretly wishing that its numerous “Energy Transfers” would fail to work!

• ## Fresh Ideas for Your Relative Speed Discussions

Posted on September 1, 2011 by Dr. Joel Bryan

Whether we realize it or not, all velocity/speed measurements are made relative to some other object. When your car's speedometer reads 55 mph, the assumption is that the change in position of the car compared to the stationary ground is 55 miles every hour. However, not all velocity/speed measurements are made relative to a stationary object. The Constant Velocity cars allow students to experimentally investigate relative speeds as the cars with different speeds move in the same and in opposite directions.
