Question:I'm a 9th grade student. I'm want to make a working windturbine for my physics project ( the one that if you spin the blades the light turns on) I really want to make it in the easiest way. I would appereciate it if you would provide the steps as well.
Answers:This might help:
Question:Our science teacher decided that giving us more time to work on science fair projects will just give us more time to procrastinate. So, I have to present my project on Wednesday (5/20) and I haven't even found a project yet!
I need good suggestions, websites, anything! Oh, and also it has to be on 8th Grade Physical Science standards ONLY. Hope you can help!
Thanks! Ah! Sorry! I meant to give a thumbs up! D':
Answers:Maybe you could test the pH of various household chemicals and foods; that conforms to the chemistry standard. You could also do a research project on forces/motion in real life. For example; intertia is present when riding a motorcycle or bicycle really fast. Maybe if you haven't done a Newton Scooter this year you could make a bunch of those. Be creative; science isn't entirely devoid of fun!
Question:i need to create something that uses 10 types of energy such as potential and kinetic energy. does anybody have any easy ideas that i can do?
Answers:try going to http://www.sciencebuddies.org/science-fair-projects/project_ideas.shtml?From=tab
they have a lot of good project ideas for physics. Try the Roller Coaster Marbles: How Much Height to Loop the Loop? http://www.sciencebuddies.org/science-fair-projects/project_ideas/home_Phys.shtml?from=Home
Question:Ok , so i'm already thinking of my gr 12 physics project for next year. We have to build a device anyhting that shows amazing physics principles, does anyone have ideas on what i should build and the physics behind it.
Here is the project handout and outline:
The main objective of this project is to give you the opportunity to design and build a device and/or simulation that demonstrates a specific topic in physics, and to perform the demonstration showing a thorough understanding of the concept at hand.
This project is worth 10% of your final mark. If you work with a partner, you will share the same mark, unless you can convince me that this is not fair.
The main components of your task will be
Details are given for each of the main components.
Planning The planning stage of this project involves two stages. First, you will submit a brief (one or two sentences) proposal of your ideas for this project. Following this, you will submit a more detailed written proposal with your ideas, preliminary drawings of your demonstration, and a list of the possible difficulties.
Construction Once you have a clear idea of what you are doing, you will build a prototype of your demonstration. This is the first stage of the construction component. The prototype is preferably a scaled or simple working version that allows you to get a better feel for what you are undertaking. It should allow for improvements to be made in the design process and should help you fully understand the scientific principles at work. Following the completion of your prototype, you will construct your actual model and show it to your teacher.
Demonstration Finally, your will present your demonstration to your teachers, peers and others on Demonstration Day. Your presentation will include an introduction, an outline of your demonstration and the physics principles it illustrates, the demonstration, reflections on your experience, and an opportunity for questions. Your presentation will be videotaped.
Okay. So here are some brief suggestions for topics with some physics principles that they demonstrate. Let me know if you like the idea of any of them and I can send you more details.
1) Water rocket: Physics principles include: Conservation of momentum, Newtons laws, kinematic equations of motion, drag forces, ideal gas laws.
[Lots of neat physics and all at a simple level where you don't have to go overboard on explaining any single concept in great detail. Also easy to build. Must be done outside! :) ]
2) Bouncy ball of a ramp: Involves dropping a bouncy ball on to a ramp at a given angle and having it bounce in to a small container at a distance that you can easily calculate. Looks very impressive when it goes in first time!!! Physics principles include: Kinematic equations of motion, conservation of linear and rotational momentum. Cheap to build (1x plank of wood, 1 ice cream container 1x bouncy ball)
3) Lenz's law demonstration: Using a magnet and a copper pipe, demostrate Lenz's law. When a magnet is dropped down a copper pipe, currents induced in to the pipe by the moving magnet actually repel the magnet's motion and slow it down.
Let me know if you have any preference of topics and i'll try to help. Also, let me know what your strengths/interests in physics are and I'll come up with other ideas.
Addition! I thought of another one.
4) Thin film interference rig. Show that you can calculate the thickness of a oil drop to within a few nanometers! Involves a large cake tin (the larger the better), a water supply (bottles of water will do), a white light (standard tungsten lightbulb, ...and an LED torch would also provide another great demonstration too!) and some clean oil. You fill the large cake tin with water, almost to the brim. Put a drop or two of oil on the surface and allow it to spread. Shine the light on the surface and see the interference colors. The color has its own wavelength. From the wavelength you can calculate the thickness of the oil and even the exact volume of the oil drop. Add more water and show how the colors (thickness) changed as the oil flows over the brim and thins out. The LED light will give a different effect than the tungsten light bulb because its light is made of only red, green and blue light, whereas the light bulb has the full range of colors (incl, yellow, orange, violet etc)
This demo has everything from thin film physics through to quantum mechanics of the LED :) Oooh! I wish I were back at school again! :D
PS. In cases like exam demos, apply the K.I.S.S rule...
