This kit shows you how to make a scale to weigh many household objects by use of Hooke's Law. Comes with a tape measure, a set of colorful plastic hex weights, a highly accurate special spring, and a detailed activity guide. Ages 7+.
The set includes a basic jack stand with the plunger and the main cylinder, four smaller cylinders, and 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…
Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and the other made of plastic. When an ice cube is placed on aluminum it turns into the water in seconds, while on a plastic block, it melts slowly. The aluminum block has a larger heat capacity and a…
With a built-in length and angle scales. Metal construction, the plane is 60cm long and adjusts from 0° to 45°. With an adjustable pulley, roller, cord, and weight pan.
To investigate acceleration, friction, gravity, and free-fall experiments. The inclined plane folds easily for storage with a special hinge, clamps to 45°, and includes a protractor and pulley. All-aluminum construction supplied with Hall’s carriage, pulley, weight pan, a solid aluminum plane, and accessories, With detail & illustrated instructions.
The apparatus has been specially designed to perform experiments on force and acceleration. 1.2 m long aluminum track has a spring-based force mechanism mounted permanently at one end. The spring mechanism produces force using a multi-position trigger. Determine acceleration speed and distance attained by applying a variable force. The track is mounted on three plastic feet. The apparatus comes with…
For investigating the nature of mass and the distinction between mass and weight. Two metal trays 130 x 55 x 23 mm are joined together with two spring steel strips of 23 mm width, the distance between the trays being 215 mm. One tray is drilled to accept 3 equal cylindrical masses. The other tray can be clamped to a…
To study the motion and behavior of gas molecules, works on 9 to 12 V DC, vibrates a small platform inside a transparent tube, which further vibrates steel balls inside the tube. Includes steel balls and two floats.
Operates on 1.5 to 6 VDC. Lifts up to 3500g. With the current direction indicator for the study of the magnetic field. Dimensions: 12 x 12 x 4cm. Weight: 14oz. Ages 10+
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along its full 360° range and measure the angle of reflection or refraction. Rotate the laser and…
Consisting of a galvanized iron box of 130 mm sides. The vertical faces are blackened dull, blackened bright, white and polished respectively, with a tubule at the top for the thermometer. Supplied with a thermometer.
