Science Fair Project: Energy Conservation?

We Answered:

show two light bulbs one which will be a regular one and the other an energy star one. then do research, the question would be haw does the energy star lightbulb conserve energy

Are there any results involving solar energy absorption using different color paints?

We Answered:

Your question is poorly worded so I'll sort of guess at what you mean.

Years ago I recall reading that NASA had determined that the best color to use for maximum solar collection was a very dark green.

I don't remember how I found this but you might be able to dig this information back out of the internet with some GOOGLE searches.

Generally black is used for an absorber and white for a reflector (one of the other answers mentions this too).

If you would like to create an experiment for a science project to illustrate this here is how I'd do it.

1. Locate a digital thermometer (I would suggest you get one from a kitchen supply store with a digital display and a temperature probe of the end of a cable so that it could be stuck in a piece of meat).

2. Create 6 color chips, I would suggest this be done by painting strips of poster board different colors. I would suggest you use colors white (paint it white don't leave it unpainted), black, red, yellow green and blue.

3. Get a large light bulb in a fixture so you can turn it on and off.

4. Mount the thermometer on the back of one of your color strips, set it at a distance of 12 inches from the light bulb and allow the light to fall on the strip for 30 minutes, take down the temperature measurement on the thermometer every 2 minutes to generate a graph for that one color.

5. Replace the color strip with the next strip and run the experiment again, recording the data every 2 minutes. Do this for each color strip.

6. Now graph all of the data on a single graph, if it works like I believe it should the black colored strip should show the fastest temperature rise and the white color the slowest.

I hope this makes sense and answers your question.

SCIENCE FAIR...SOLAR...HELP!! ASAP?

We Answered:

The cost of new solar panel is around 3 U.S.$ per watt.You can buy any old one for lessor cost. Instead of multi meter go for LED bulb or any low watt low volt bulb to measure the energy.I am using a 30 watts 12 volt motor that drives my split type evaporation unit .I have just removed the evaporator and replaced the 230 volt motor by 12 volt motor.It gives sufficient air during the day time.Shortly one like this will be exhibited in our non conventional energy park.

what should i do for my high school science fair project?

We Answered:

you can try to use solar energy to cook food or warm food

How can I make my science fair topic testable?

Maybe pick up some solar cells and some LEDs. Make a little diorama of a house powered entirely by solar power, with the LEDs as the house's lights (use a desk lamp to model the sun, and power the solar cells).
