Science Buddies: "Ask an Expert"

Dear science buddie,
My name is megan d. from Dodson middle school. Im doing a science fair project and need your advice. My topic question is what is the relationship between the positioning of the fulcrum and the load it can lift. I know its sounds complicated ,but it is really quite simple. I will be creating a teeter-toter type thing out of wood. My dad is making a fulcrum out of wood and we have a wooden plank. I am measuring in grams because it is universal. I am using weights that have been converted exactly. In this project, I will have the fulcrum in various places and always have a certain amount on one of the sides. I am still not completely sure about the techniques that I use. Can you please critique my project and help me to have the best project that I can have.
Yours truly,
Megan d.

Hi Megan!

Sounds like an excellent project, and, by the way, it's called a lever. Other people may have more concrete suggestions.

Simplifying a bit, some background can be found by supplying "what is the relationship between the fulcrum and the load?" to answers.com. Note subtle wording changes can have a major impact on output, so you may need to modify your input. Sponsored links, none here, are just trying to sell you something.

There is a similar project in the science buddies website at:

It uses a see-saw and kids on a playground, but it gives some examples of some measurements you might want to try.

hi, my name is alix deming, and i go to Capistrano Valley Christian School, and i need help because i can't find anything on my topic. my topic is about spectrum and color productions-prims; and my question is how does spectrum and color prductions make prisms? how am i supposed to experiment it when i can't find anything on it? please help me!!

Hi Girl4God!

You can supply "how does spectrum and color productions make prisms?" to answers.com to collect more information. (note, you have fix the typo in productions first before you use a search tool.)

In the top hits we have:

- Television Production: Principles of Color
- Several with science fair projects

You can get the URLs from the answers.com output.

A further suggestion is open a new topic, rather than bury your post in an existing topic. It can get lost there!

Notes:

Beware of sites that are trying to sell you something, "Sponsored Links," but they can be buried in "Web Results."

The results of the query is dependent on the input, so some experimentation is needed. (In this case, there was no output until the typo was fixed!)

All,

Ok, it's a case of the pot calling the kettle black. I had my own typo. In my last post please substitute "You have fix" with "You have to fix."

I'm sorry; I need to do a better job proofreading before I hit the Submit button.
