Can someone suggest a few science experiments we could do at our school for the Science Exhibition ?
Yes I have done so but the topics seem either extremely simplistic or require great amount of knowledge in electronics and other fields. I would like to do something in electricity and optics.If you could give me some chemistry topics as well I would be really happy.berkeman said:Welcome to the PF.
You said in your New Member Introduction post that you are in high school. What kinds of experiments/projects have been done in the past? Have you done a search online for High School Science Fair Projects? You will get hundreds (if not thousands) of suggestions.
What are your favorite areas of science? Physics? Chemistry? Biology? Engineering/Robotics?
Well, a fun one is to use 2 audio speakers and light first-surface mirrors (FSMs) to make an x-y laser pointer deflection system. You need to figure out how to mount one end of the mirror to the center of the dust cap in the speaker and the other end to some sort of hinge mechanism near the edge of the cone (which is fixed with respect to the speaker enclosure). That way, as the speaker cone vibrates in and out, the FSM rotates about that hinge. An even better arrangement is to figure out some mechanical mechanism that attaches to the dust cover and the edge of the speaker, and allows the mirror to rotate like a teeter-totter so that the middle of it is just changing angle and not moving in and out with the speaker cone.Subrahmanyan said:I would like to do something in electricity and optics
