# Cool Labs ##### Quantum Lab (Inquiry)

Something that is quantized exists in multiples of a set quantity. Examples are charge [1.6 x 10-19C] or quantum energies of photons. Planck and Einstein predicted that light existed as discrete bundles called photons. Since they could not see a... ##### Momentum - Tailgated by a Dart

In this lab, students will learn to estimate the speed of an object by applying conservation of momentum to an inelastic collision. Energy is not lost its transferred from one object to another. Students will fire a dart into the... ##### Density Rods

The Density Rod Set consists of two rods. The aluminum rod sinks in warm water and floats in cool. This is because cool water is more dense than warm, and the aluminum rod is made to be between those two... ##### Quantum Lab

Picture of a Lab – Different Graph Types Station #1 investigates the relationship between force and displacement of a stretched spring. Students will discover a direct linear relationship, with an equation of the form y = mx + b. Station... ##### Density of a Solid

Regular and irregular objects will be used. Students will devise a way of finding the volume of each object – calculating the volume of a cube or using water displacement for irregular objects. They will calculate the density of each... ##### Acceleration Force and Mass

Students love fast moving experiments, but higher speeds often require higher technology. That can challenge the budget and students’ ability to use the technology. These simple, but highly accurate photogates remove both barriers. No costly computers are needed, and set... ##### Waves on a Helical Spring

Students investigate properties of mechanical waves using a helical spring: wavelength, speed, reflection, standing waves, interference. Neither amplitude nor frequency affects wave speed. As wave frequency goes up, wavelength goes down, and vice versa. Wave pulses can interfere constructively (adding... ##### Tuning Fork Interference

Tuning Fork InterferenceTwo waves, when traveling through the same medium, will superimpose upon one another, causing interference. In the case of sound, the two sounds will combine to form a single sound. This lab asks students to combine the sounds...
