This pre-assembled DC motor is designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks. The polarity of the magnets can be reversed to change the direction of rotation. The motor can also be used with a rheostat to observe the change of speed with the change of current. The DC motor can stand vertically or horizontally and operates on a 1.5V battery (not included). It comes in a sturdy plastic storage case with a student activity manual Shipping weight: 11.45 oz., dimensions: 5.5" x 4.5" x 2.5".

Serves to demonstrate Boyle's Law. Shows what happens when gases are subjected to increased pressure. The plastic syringe, with solid wood base and platen, is constructed so that the calibrations denoting interior volume read right side up. As masses of bricks, books, or other heavy objects are increased, the gas in the syringe is compressed to smaller and smaller volume. The kit includes: 1 Syringe Cylinder w/ Cap, 1 Syringe Piston, 1 Base, 1 Platen.
