Title: Curve Balls
In this Science Update, from Science NetLinks, you'll hear about the mathematics behind baseball pitching. Mathematician Chuck Romine discusses a new mathematical model that describes the trajectory of a curve ball. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.
Standard(s): [S1] PHY (9-12) 4: Describe quantitative relationships for velocity, acceleration, force, work, power, potential energy, and kinetic energy.
Title: Light as a feather....or is it?
Feather and Coin in a Vacuum Web Address URL:
[SC2015] PHYS (9-12) 2: Identify external forces in a system and apply Newton's laws graphically by using models such as free-body diagrams to explain how the motion of an object is affected, ranging from simple to complex, and including circular motion.Digital Tool Description: Students often have a misconception about the force of gravity of objects of different mass. This video shows an MIT student demonstrate with a clear tube that contains air how objects of 2 different masses, a penny and a feather will fall as expected (penny hits first) and then how the objects experience equal forces of gravity in the tube with air removed (vacuum). The video itself has no voice over or music, simply read-over text so it is not dramatic but a simple demonstration.
Title: Electromagnetic Waves
Digital video Web Address URL:
[SC2015] ESS (9-12) 1: Develop and use models to illustrate the lifespan of the sun, including
energy released during nuclear fusion that eventually reaches Earth through
radiation.Digital Tool Description: Use the you tube video presentation of the "electromagnetic spectrum song" to aid in student remembering the electromagnetic spectrum.
