What is the perfect topic or subject for the science fair to work on?, wither it is Biology, physics,........?

Question

please help me to find a subject. I prefer the subject will be easy to complete, which is not too hard, or with resorsese you can not find easly. HELP!!!

Answer 1

You don't give your age!

A middle school kid tested dogs to see if they are left or right handed. The kid put dog treats in a container so that the dog would have to paw at the container. It looked like a fun experiment.

A child in my daughter's grade school tested particulate pollution by taking circles of cardboard, smearing them with vasoline and placing them on sticks all over the city.

We tested miracle-gro versus other soils and found out that miracle-gro plants do grow twice as big.

We also got petri dishes and filled them with agar and then touched them to various parts of our body to see what grows on us. There were all different kinds of bacteria.

A psychology research project might require only people and, say, a questionnaire. A biology project might require a few seeds and cups or a piece of bread and a plastic bag. A physics project might include only different items that you drop from a height or pulleys and levers used to lift objects.

For several years in a row, we attended a neighborhood school's science fair.

I do remember is that it was a kid's idea about her experiment, and a kid's way of expressing his ideas or trying to find a way to test his hypothesis that was the most interesting. This is all about your development, broadening your understanding of what science is and how we gain knowledge through it, and strengthening your ability to express yourself to others. Everyone's right - do something that interests you.

Here's a fun experiment I remember from the neighborhood fair - It's a test of memory. Arrange several objects, like key, film, paper clip, bookmark, mint,etc on a tray.

Have your test subjects (one at a time) study the objects for two minutes. Then, cover the objects and ask each subject to write down or name all the objects they remember. Count up everything they remember - each person's score is one piece of your data.

That's the basic activity. What makes it an experiment is that you have a hypothesis, a guess, about this subject. You might guess that girls or boys or neither would score better than the other in this memory test.

Your evidence would be the scores (number of items remembered) that each person got, and you would, of course, note each subject's gender.

Heck, you could hypothesize that short people (must define it in inches!) would remember better than tall and divide your groups that way.


Let's say you did gender. you might say "I hypothesize that girls will remember more items than boys." Once you know your results, you should ask why you got them. What does research on memory and gender say?

Or, your different test groups could be the conditions under which you test. Test each person under several conditions unless you have lots of people, and then have three groups, with each person experiencing one condition.

By condition I mean things like silence, music, outside, in a mall - the environment it takes place in. You might hypothesize that people who took the memory test in a mall would score worse than people taking it with music or silence.

Then, you'd see how your results match your hypothesis and try explain why. You would suggest areas for further research and you would mention any weaknesses in your study.

For example, 30 people is the minimum number of subjects a study needs to be valid. If you don't have 30, mention that your data is suggestive and more subjects are needed. Or, all your subjects might be from the same family, neighborhood, ethnic group, income level, age group, etc. This means your results have limited application and you'd mention that as a weakness. This is all good, because science wants to collect facts from testing hypothesis. Eventually, a solid body of facts permits that formulation of a theory, which is the best explanation for a body of facts.

Not only does science want its facts straight as best as it can in the beginning, it wants to revise continually as new facts are observed or gathered.

This is why electricity, gravity, and evolution, areas of science with huge supporting bodies of facts undergirding them, are called theories. Theories, in science, are not to be confused with hypotheses. As we can see from the development of physics, from newtonian physics to relativity to quantum physics and beyond, many theories are still evolving as facts become known and our ways of knowing change or improve.

One tough thing about science is that we can more easily find what we're already looking for, we can find those things our tools can detect, and we have to struggle against the way we've always thought affecting new ways we need to think. How long did we deny tool use by non-human animals because we'd all been taught only humans used tools?

So, what can you contribute to the great human endeavour of science? What do you want to know and how can you best learn something approximating the truth?

Have fun, work hard, dig deep inside yourself. This is, after all, all for your benefit, dear!
