Need an idea for my science fair project?

I am participating in a Middle School Science Fair and am doing my project on tidal power. I need an idea for an experiment that I am capable of doing for the science fair. If you have any suggestions please answer!

wow, thats even a better idea, finding the ones that were award winner science projects

experiments diffculties, help?

here is the problem :
i am doing a little experiment for my school & it counts as half of my science grade. i need to know if this question id possible.
if i have a freezer set to 6 degrees and a fridge set to 38 degrees, is it possible that the container filled with water in the fridge didnt freeze but the container in the freezer did?

As long as we are taking degrees Fahrenheit here, water freezes at 32 degrees. That means that in an environment where the temperature is greater than 32, the water will remain liquid. If the temp is 32 degrees or less, the water should freeze. Let’s look at each of your environments.

The freezer is 6 degrees. This is less than 32 degrees, so we would expect the water to freeze.
The fridge is 38 degrees. This is greater than 32 degrees, so we would expect the water to remain liquid.

What you are describing is not only possible, but it is the expected result.

What are some quick and easy science fair experiments?

gimme somethin good

Materials used:
1.Two (2) raw eggs
2.500ml white vinegar
3.½ kilogram (500 grams) of sand
4.Two (2) clear, covered containers
5.External measuring calipers
6.Ruler

The experiment:
First, both eggs need to be measured for height and width. One egg will be put into a container and covered with white vinegar. The other egg will be put into a container and covered with sand.
The question:
Will either of the eggs grow bigger? Which egg do you think will grow bigger, and why? Will either egg grow smaller? Why?

The directions:
1.Write down the measurements of each egg on your lab page.
2.Write a hypothesis stating which egg you think will grow bigger, and why.
3.At the end of the experiment, write down the measurements of the eggs.
4.Write down the results of the experiment.
5.Was your hypothesis right or wrong? Why?

Instructions on making a simple metal detector using a CD case, calculator and an AM radio?

heard this on the radio but didn’t catch the details.
any info would be great. looking for simple science projects for kids using stuff around the house

This sounds like an urban legend. Modern metal detectors use an oscillator to produce an alternating current which flows through a large multiturn coil in the bottom of the detector. This coil produces a magnetic field which causes current flow through induction in nearby metal. A second coil detects the magnetic field in the nearby metal (induction again) is amplified and drives a detector circuit.

If you had a very crumby AM radio from the 1920′s, it would probably detune the station you were listening to if you got near a car but I don’t see how the parts you describe could work.

Science Experiments for junior school?

Hey, I have recently received position of science ambassador at my school.
Just we have to make science experiment s for the little kids and i need ideas.

We can do practily anything, I have already thought of doing the ‘flame test’ of buring irons to make colors, any other ideas appreciated

Botany

Photosynthesis

Electro-Magnetic Fields

Solar System

Astronomy

Litmus

What are some good science projects for kids that require household items?

I want to do a simple but cool science "project" and i know if you mix baking soda and vinegar, it will bubble and everything. But do you know any other cool science projects that require household items. Like: Baking soda, any food, or drinks that you would use+ other items that many people have. Thanks!!!

Here are about a dozen fun home experiments>
