Lab #36.8 Magnetism: Motor Madness
Lab #36.8 Magnetism: Motor Madness
In this activity, students will investigate the principles that make electric motors possible.
Equilibrium and Torque
Equilibrium and Torque
Students will use a center-pivot lever to grasp balance and torque.
Collisions on an Air Track
Collisions on an Air Track
In this lab using an Air Track, students will investigate elastic and inelastic collisions on an air track. Evaluate conservation of momentum and energy. Download Teacher Notes and Student Worksheets...
The Bouncing Dart
The Bouncing Dart
Students will collide each Bouncing Dart end with a massive (1kg or more) cart, observing the pendulum's motion and measuring the distance the cart moves.
Gravity and Motion
Gravity and Motion
Students will predict and eventually measure the acceleration of a car on a ramp at different angles.
Lab #36.5 Magnetism: Electric Magnetism
Lab #36.5 Magnetism: Electric Magnetism
In this activity, students will investigate the electric origin of magnetic fields.
Pressure and Temperature
Pressure and Temperature
Demonstrate Charles' Law by allowing students to pressurize a plastic bottle and measure the increase in temperature of the air inside.
Gas Laws: The Cloud Machine
Gas Laws: The Cloud Machine
Students will use water vapor, smoke, and a bottle to form clouds.
Lab #36.2 Magnetism: Seeing Magnetic Fields
Lab #36.2 Magnetism: Seeing Magnetic Fields
In this activity, students will explore the patterns of magnetic fields around bar magnets in various configurations.
Wind Instruments Inquiry
Wind Instruments Inquiry
Students will use three simple toy instruments to explore fundamentals of sound and frequency in this inquiry exercise.
Doppler Effect
Doppler Effect
The Doppler effect occurs when there is relative motion between the source and the observer (recorder.) When the distance between the source and the observer is decreasing, the frequency is...
Resonance: Speed of Sound
Resonance: Speed of Sound
In this lab, students will use a tuning fork to find the resonance point of a column of air. Then they will use a simple formula to find the speed...
