Concepts Every device has related science
and engineering concepts that you need to know to
do "informed designing." Each activity
that is showcased in DITC has pages that address
Key Concepts. These pages provide tutorials on how
the devices that students are designing work, which
design variables most affect a product's performance,
and typical misconceptions that you will find students
working from and that you will need to address when
you plan your lessons.
