Excellent flight unit completed by a teacher who also happens to be a Private Pilot license holder (me!). Includes PROPERTIES OF AIR, barometers, etc. in workbook type form. Also includes questions related to NOVA's WRIGHT BROTHERS FLYING MACHINE documentary available online. Finally, includes aircraft instrumentation, control surfaces and instruments, as well as a post unit mini-quiz. Answer key not included... but science teachers and informed adults should have no problems.
