Five identical triangles can be arranged to show squares on each of the triangles sides, but one at a time. Demonstrating the Pythagorean Theorem involves showing the relationship between the sides of a right-angled triangle. By using geometric models or diagrams, students can see how the square of the hypotenuse is equal to the sum of the squares of the other two sides. This fundamental principle in geometry is crucial for understanding various mathematical concepts, including distance calculations, vector magnitudes, and trigonometric identities.

Using a wooden cube with centimeter square rules on each face to illustrate the volume of one liter helps students understand and visualize cubic measurements. Removable blocks of one cm² and one cm x one dm assist in teaching concepts of volume, spatial reasoning, and the metric system's units of volume.

An orange and white 4-sided stick that is graduated in meters, decimeters, centimeters, & millimeters. Useful for showing the relationship between SI prefixes, or as a more colorful/aesthetic version of a regular meter stick. 

Set of orthogonal axes representing the x, y and z coordinate axes. Both small and large available.

A 4-sided stick that is graduated in meters, decimeters, centimeters, and millimeters. Useful for showing the relationship between various SI prefixes.

An assortment of different capacitors that can be shown to students.

A Van de Graaff generator is used to charge a half-sphere conductor. Two styrofoam balls coated with electrically conductive paint are placed near the half-sphere. One is on the outside and the other is on the inside. Due to spherical symmetry, the ball on the inside does not feel any net electrical force, whereas the ball on the outside is first attracted (because it is neutral) and then polarized, which causes it to be repelled.

Suspend an irregular object from several points and find the center of mass with a plumb bob.

A mass on a pulley accelerates the various carts along the air track This demonstration involves using Pasco carts on a track, pulled by a falling mass over a pulley, to illustrate Newton's second law of motion. As the mass falls, it provides a constant force that accelerates the cart. By timing the motion of the cart and measuring the distance traveled, students can observe the direct relationship between force, mass, and acceleration. This setup helps to clearly demonstrate the principle that acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass, reinforcing Newton's 2nd Law.

Bumper carts equipped with can crushers demonstrate the effects of inelastic collisions, where kinetic energy is not conserved, and deformation occurs. This setup highlights the practical applications of collision principles and the energy dissipation associated with inelastic impacts. PASCO SE-8747.
