Childrens Lab for Optical Experiments

thingiverse

These hands-on stands for lenses, mirrors, LEDs, and cards enable kids to freely experiment with optical properties by rearranging them and witnessing the outcomes. Perfect also for measuring focal lengths of your 25 and 27mm lenses. To obtain a lens, visit a supplier; I've found this site useful: http://www.surplusshed.com, where you can order lenses for about 10 to 15 dollars a pair. Now, have fun! On November 23rd, 2015, the project was updated with the addition of a 1" prism stand. To assemble it correctly, one side of the equilateral base of the prism should be exactly 1 inch. --- Optics Lab Project Objectives: Explore refraction, reflection, spectra, and other optical phenomena through hands-on experience. Audience: This project suits children in 4th grade and above, as well as college students. Preparation: Acquire lenses, index cards, film negatives (or Viewmaster reels), and 1" mirrors. Steps: - Rearrange the lenses, cards, and mirrors to follow various online courses on optics. - With this system, measure focal lengths, break down light into spectra, and demonstrate that light behaves both as a particle and wavelength.
