Science Experiments

how are people affected by social impacts in solar power?

To make sure they are accurate.

When naming a science project, think about the question you want to answer. The project name is just rephrasing the Question into a statement.

ex.

Question: do plants grow better in sunlight or under florescent lights?

Project Name: Plant growth in different lighting conditions

It depends on the experiment. You could use any graph that would best represent the data that you have gathered from your experiment.

bar graphs, line plots, and line graphs are just a few examples.

variable

It depends on what the project is on.

Yes. In the same way that a Frisbee or disc will do. When angled correctly (approximately 45 degrees - between straight up and level to the ground) - and throw with the right amount of force, and using the right technique, the boomerang will return to its original position - albeit slightly lower or away from it's original launch position.

This is due to the slowing of its acceleration or forward momentum because of air resistance. One the object has stopped traveling upwards, it begins to glide back down to earth.

It glides up and then down because it cuts through the air, and its shape forces the air around it, helping prevent it from moving forwards and down. Imagine there is a slide made from air. This is what the boomerang makes as it travels through the air. This only happens when the boomerang has a correct shape.

They were originally used by the aborigines to hunt birds with - as if they missed, the hunters could quickly retrieve their weapon.

Not all boomerangs were designed to return. Some were designed to simply be for stunning or killing animals.

There are many possible science projects dealing with insulation. For example, build several small containers with each wrapped in a different insulating material, then put an icecube (all the same size!) in each container, and see how the time needed for the icecube to melt varies depending upon the type of insulation used. Or put a small light bulb in each container (all of the same wattage!) and then measure the resulting temperature in each container after ten minutes. Or make blankets of various different insulating materials and see which one keeps you warm at night the most effectively.

conducting means controlling so controlling the experiment is find the result of the data plan.

A data analysis is when you interpret and analyze your results. If you made graphs, include and explain them here. Your answer should include the questions.

variable is a factor in an experiment that can change

i was in 5th grade before and i did how volcanoes are formed and i won 3rd place in the city run off yay

Wear a safety-mask, rubber dish-washing gloves, (possibly raincoat for protection),

(depending on age) have parental supervision, Lay-down newspapers (lots... if you don't have newspapers use paper towels again lots), Long hair? tie it back in a ponytail, and if your having difficulties please ask your parents... better safe then sorry.

When presenting to a group of people, whether judges or others, be confident, be clear and be loud enough to make yourself heard by your audience.

Yes. It is a great science fair project. Easy and fun

When one magnet moves, it generates a changing magnetic field around it which induces a current in the other magnet, causing it to move in response to the changing magnetic field. This is due to the magnetic attraction or repulsion between the two magnets based on their alignment.

Charging a balloon creates static electricity, which induces a temporary electric field around the balloon. When the charged balloon is brought close to a stream of water, the water molecules polarize and are attracted to the charged balloon, causing them to bend towards it.

Acknowledgement means some one that help you with your projects is like giving the person credit

In my opinion, the best science fair project that you can do is something that truly interests you. If you do something that you are interested in studying, you are more likely to put more interest and work into. When the judges see how much time and effort you put into the project, it definitely won't hurt!

gathering data.

it's not an investigatory project 'cause you're not investigating, you're making a freakin' object! >.<

That depends on the experiment.

So the experiment's results are more reliable
