"PARKWAY PLASTICS, INC."

This unique metal launcher has multiple settings, so launch speed and angles may vary.

Relate Motion to Sound

High Quality.

Observe how charges affect one another and propose an explanation in terms of charge distribution.

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

Ideal for studying collisions in two dimensions, these pucks can be supported on plastic beads or levitated with air from the balloons to reduce friction. Use on any smooth, flat surface. The pucks measure 10 cm in diameter, and one puck is twice the mass of the other two.

Comprehensive and High Quality.

Explore the factors affecting the electrical resistance of conductive modeling dough.

Design and conduct an experiment that analyzes the motion of a conical pendulum.

Explore charging by induction and discover how a Leyden jar stores electric charges.

A fun tool to help teach water concepts.

View Spectra with an Accuracy of ±1 Nanometer

Great for teaching that density depends of both mass and volume, students can't seem to put these spheres down! Two steel spheres are great for teaching the skills of observation and deduction.

An excellent set of materials for demonstrating electromagnetism and induced currents, the set includes two electromagnetic coils mounted on plastic saddle blocks, round and square iron cores, split round iron cores, a double core, and a card for showing lines of force. Set of two.

These free-running plastic pulleys are durable in design.

A set of eight coils wound on individual plastic spools. Each coil has two binding posts.
