"Avantor"

Explore the diffraction patterns from different gratings, then determine the width of a single hair.

Create maps of equipotential lines and the electric fields that exist between two charged surfaces.

Determine the coefficient of friction by measuring the minimum angle to keep a ladder from slipping.

Analyze the diffraction pattern of hydrogen and determine the Rydberg constant, R.

Measure the wavelength and threshold voltage of an LED and calculate Planck’s constant.

Explore precision and error in measurement.

Determine the landing position of a ball launched horizontally from the top of a table.

Find the spring constant of a projectile launcher using the potential energy of its projectile.

Essential supplies to build and measure electric circuits.

Determine the spring constant of a spring-powered launcher by analyzing the work done on a system.

Use the ideal gas law to determine the ambient pressure in the room.

Extend your photogate to accommodate any width.

Useful for collision and pendulum experiments.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

Great for classroom projects and demonstrations.
