Every Breath You Take
Learners explore the nature of the air we breathe by observing petri dishes that have accumulated particulate matter from the atmosphere. Students make mathematical calculations and inferences about the effect of this matter on...
Curated OER
Paper Airplanes
Students study paper airplanes. In this lesson on aerodynamics, students print out the folding directions for making paper airplanes and after making the planes test their paper airplanes to see how well each flies. Students weigh...
