Constructing a Spectroscope
Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
Curated OER
The Doctrine of Signatures
Students use the graphing calculator and the core equation: y=Ax^2+Bx+C where A = the acceleration of gravity/2, B = the initial velocity, and C = initial height above ground to graph parabolas for Earth and Mars. They experiment with...
