Here is a set of printable cards about “Exponential Functions” for use in a Precalculus or College Algebra class. I use these problems as part of teaching Chapter 3 Section in “Precalculus with Limits: A Graphing Approach” by Larson, but any Precalculus (College Algebra) textbook will have an equivalent section. Inventory of this download: Section_3.1_Group1.pdf: 56 cards (7 sheets) of problems that ask a student to determine a particular value of a simple exponential function. These problems ju

This activity uses the wild physics of the Breakthrough: Starshot initiative to teach about the Laws of Motion and the incredible challenges of interstellar travel. I have used this as a short lab, but usually this is just a classroom activity or a homework in my Astronomy class. If you aren't familiar with it, Breakthrough: Starshot proposes sending a very small (30 g) spacecraft to the nearest star system, using a solar sail for propulsion. How practical is this? How great is the accelerat
