Radio Silent

Sorry I haven't posted in awhile.  We are ending the year with solar cookers.  Kids are designing and building solar cookers.  Next Monday we will feast.

Taking Orders

Orders for shirts are starting to roll in.  So we printed a bunch today.  We took turns loading, printing, heating and folding shirts.
Getting it right.
It takes a team.

Stopping the Wave

We started a stop motion project on sound waves.  Students had to explain how changing frequency and amplitude affect a wave.

Sometimes I Make Poor Choices

Today I let kids play with a tone generator and an oscilloscope.  The idea is that they can see how changing the Frequency and Amplitude of a sound change the wave.  Below is the audio from one of my four classes.

A Business is Born

We have a screen.  Today we taped it up and started to learn the process of printing shirts.
Some Squeegee work.  Squeegee is such a cool word.

Playing with Sound

Today we start looking at sound.  I had the kids use twistedwave.com.  It is a web based audio editor to record a sound and then manipulate the wave to see how the wave is affected.

Then we fail.

Today we attempted to burn a screen.  We set up our screen, set it up correctly, and exposed it.  Round 2 tomorrow.
