Long, pure sounding aluminum tuning forks.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

Multifunction Capability in One Affordable Instrument

Designed for Physics and Physical Science experimentation.

Reliable and User Friendly

These long-lasting aluminum tuning forks have a full sound.

Equilateral prisms, made from high quality clear acrylic sheet.
