Collection of Science Demonstrations

This is an amazing resource:   a collection of science demonstrations from Harvard Natural Sciences Lecture Demonstration Services.

There are hundreds of demonstrations in the archive.  Each entry includes an in-depth description of the scientific principle(s) on display in the demonstration, as well as detailed instructions on how to execute the demo.

Topics include Newtonian Mechanics, Light and Optics, and Thermal Physics.  There is also a collection of mathematical demonstrations, as well as a small set of videos.

Math Haiku

There are many reasons I personally love to write, and as a math teacher, I love getting my students writing about math.

One easy way to do this is to have students write math-themed haiku.  It’s a simple exercise, it gets students thinking about math in a different way, and the elegance and efficiency of the style is reminiscent of mathematics itself!

So enjoy some math-themed haiku from my Calculus students.

Solving math problems

Getting lost along the way.

You’re on the right track.

Mathematicians

Must always seek out patterns

To make connections. 

Limit of a curve.

Tangent at infinity.

Straight line asymptote.

Triangles are shapes

They have sharp, pointy edges

Don’t let them poke you.

Got a good math haiku?  Let’s hear it!
