Demo: Newton's Second Law (Fan)
The Smart Fan Cart is set on one thrust setting and the mass of the car is varied, yielding different accelerations. Then the Smart Fan Cart is set on...
Demo: Newton's Third Law (Force Vectors)
Two Smart Carts with Vector Displays are placed at rest with their rubber bumpers against each other....
Demo: Newton's Third Law (Fan Cart)
Demonstrate which way the Smart Fan Cart moves without the sail. Then demonstrate the Smart Fan Cart does not move when the fan blows into the sail. Finally,...
Demo: Impulse and Force
While viewing the Force on Smart Cart Vector Display, the cart collides with the end stop with the magnetic bumper and then with an added paper bumper....
Demo: Collisions
Collide two Smart Carts of equal mass: As viewed on the Vector Displays, the forces are equal and opposite and the accelerations are equal and opposite....
Demo: Simple Harmonic Motion
A Smart Cart with Smart Vector Display is attached to a spring on an incline. Mark the equilibrium point. View and compare the velocity, acceleration,...
Demo: Buoyant Force
Demonstrate two ways of determining the buoyant force on a submerged object: (1) Buoyant Force = Weight – Apparent Weight; (2) Buoyant Force = Weight...
Energy Dynamics
Students use EcoChamber containers and a carbon dioxide gas sensor to estimate energy flow and carbon cycling within a variety of detritus-based ecosystems.
Plant Pigments
Students analyze spinach pigments and chloroplasts using paper chromatography, a colorimeter, and a spectrometer to understand how plants capture light...
Transpiration
Students use a pressure sensor and a weather sensor to investigate the rate of transpiration in plants under normal and humid conditions.
