Youngs Modulus Supplementary Set, 12 Flat Bars Made Of Steel (Thickness: 2 / 3 mm), 6 Flat Bars Made Of Aluminium (Thickness: 3 mm), With The Effective Lengths Of 200, 300 And 400 mm And The Widths Of 10 And 20 mm For Measurement Of Elastic Deformation.
Number, Measurement and Space, module establishes equivalence of sets by a one-to-one exchange of objects. Eg Upsetting equivalance (destroying conservation of numbers) by adding one object to a set, or taking one away, helps introduce vocabulary for comparing quantity
Free Fall Apparatus Economy, for determination of the gravitational constant ft gft, This kit has a wooden base, 1.1m rod and a movable electro magnet, can be moved anywhere on the rod, when the ball is released the timer is triggered and stopped one the ball his landed on the base
Photoconductivity, Multipurpose power supply. Electrical safety tested. Marked analyzer & polarizer for angle measurement. Photo current is studied as a function of the voltage applied to the photo resistor at a constant irradiance.
