Ideal for exploring force of friction.

Observe the density across different materials and sizes.

Used for auditory responses. Available with or without fixed weights.

Explore beautiful 3-D patterns created by a magnetic field mess free.

Organize a DIY race, fueled by hydrogen generated electricity!

Wide range of cubes for density experiments.

Small electrolysis apparatus with beaker included.

Designed for Physics and Physical Science experimentation.

This excellent quality electrostatic generator consists of a charge generation system, an aluminum collector sphere, and an electric motor drive on a sturdy base.

Ideal for classroom demonstrations of centripetal acceleration and transformation of potential energy into kinetic energy.

This unit is ideal for beginner electrolysis experiments.

These ARE the micro:bits you've been looking for!

Cubes have 2 cm(0.78") sides with a hook for density investigation and specific gravity activities. Element stamp indicates material.

Great for classroom demonstrations involving power plants or conversion of energy.

This is a classic example of thermodynamics in action.
