Stewart’s Physical Science program is amazingly cool.  It is a CD-ROM program that he uses daily and it walks him through experiment after experiment.  He builds machines and then makes hypothesis as to how they will perform in certain tests.  He then conducts the test and evaluates his hypothesis.  Very neat stuff.

PS – I don’t make them dress the same – they did that so they could be on the same team at CBS.

Little sisters are interested, too.
