Ocean Acidification
Students use a pH sensor to explore the effect of excess atmospheric carbon dioxide on water pH.
Spectroscopy
Students use PASCO’s Spectrum Cards to model the use of spectroscopy to identify elements present in a compound.
Graphs of Motion
What do graphs of motion look like? The Smart Cart is a device that displays its motion—position, velocity, and acceleration—on your computer in real-time...
Motion Graphs
How do we predict and object’s position at a later time? Graphs and equations are valuable methods for describing the motion of an object.
Acceleration on a Ramp
What is acceleration and how does it relate to speed and velocity? A car rolling down a ramp accelerates. A car given an initial velocity up a ramp accelerates...
Newton's Second Law
How is an object’s acceleration related to the net force acting on the object? When the forces acting on an object are unbalanced, the object accelerates....
A Model for Accelerated Motion
How can a velocity versus time graph be used to determine displacement? An object’s position changes as it accelerates.
Hooke’s Law
How are force and displacement related when stretching a spring? In this investigation you will measure force from the spring, and spring deformation (spring...
Static and Kinetic Friction
What determines the force of friction? Friction is everywhere and can be either helpful or wasteful depending on the situation.
Projectile Motion
What is the angle that maximizes the range of the projectile? How are the projectile motion equations used to calculate a projectile’s range? Projectile...
