positioning the narrow plate between them creates a double-gap arrangement where students measure the fringe spacing directly and calculate wavelength using the standard two-slit equation

hands-on experiments

A helium spectrum tube lets students observe the same signature that gave the element its name and connects the bench-top measurement directly to how astronomers identify the composition of distant stars today

The Millisecond Timer is an easy-to-use digital timer designed to measure time intervals from milliseconds up to 9999 seconds

Here's an easy way to measure the speed of light in your classroom without wrecking your budget

Investigating the Center of Gravity Classroom Kit Sensors & Data Collection positioning the narrow plate betweenThis easy to use classroom kit lets students explore how gravity acts on an object and teaches them a simple method of determining an object's center of gravity. The set investigates five different amoeba like shapes including a teacher's larger "challenge shape" with its mass surrounding a point in mid air.
