Hydraulic Jack Model
The set includes a basic jack stand with plunger and a main cylinder, four smaller cylinders, a set of connecting hoses and valves. Smaller cylinders can be easily connected to a basic jack stand with a large main cylinder. Students can lift a heavy object, such as a stack of books, by applying a small amount of force to one of the four smaller cylinders. Students can adjust the mechanical advantage by using different input cylinders. Device may also be used to demonstrate Boyle's Law using air or other gases. With Instructions

Ice Melting Kit
Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and other made of plastic. When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block, it melts slowly. The aluminum block has a larger heat capacity and a higher thermal conductivity, while the plastic block has lower values of both parameters. With instructions.
