photosynthesis

[Sandra Johnson]

hello everybody.

i read a software review in american biol teacher (3/2002) about 'like
clockwork' by david walker. i haven't been able to get more info about
it and remember that somebody once mentioned a photosynthesis book for
kids by the same author. does anybody know anything about 
'like clockwork' including how to order it? our bookstore can't seem to
find this software.

thanks.

sandra
