Let's look at your astronomy science fair project!


Like we said...astronomy science fair projects are fun and educational. This one's no exception. If you like Just staring into the night sky and gazing at all the wonders you see, you'll get right into this one.

But today we're asking you do be a little more than that. We're asking you to be a scientist too. And good scientists always research their subject first. So...

...let's research the sky. This project focuses on the moon. So, guess what we need to research?...

That's right! We need to research the moon. So find out all you can about the moon. Where does its light come from? What are the dark spots we see on it at night? Is it really made of green cheese? (OK. Maybe not the last one!)

But don't stop with just the moon. Do some background research on other "heavenly bodies" such as the sun, the stars and meteorites. These subjects may relate to your subject.

This project deals with time as well. So it might be good to do some research on sundials as well.

Use a calendar with the phases of the moon marked on them to help you determine what the moon will look like. An almanac will help you figure out when the moon will rise and set. You can usually find an almanac at your local library.

And don't forget to check your local weather report. Cloud cover may keep you from seeing the moon. So come up with a plan that will give you plenty of time to do this astronomy science fair project if you live in a place with lots of rain.

Consider everything! Find all you can about the sky. Ask an adult, or get on the internet to find out as much as you can. Your local library may assist you as well. Ask the library assistant to help you find books about your subject.

All this should give you enough information to ask the important question...

Can the moon be used to tell short periods of time?

This is a good question because we can try it out in our backyard or other open place. But don't try it yet. We need to answer our important question first!

Let's do that now.

Do you think the moon can be used this way?

Write it down on a piece of paper. Don't change it until you see what the experiment does first. Remember...

...we call this guess our hypothesis. It's the most important part of our project!

Now it's time to get your stuff from the list above. Let's move to the next step.


Now comes the fun part...

...let's start our astronomy science fair project!

You'll start out by simply watching...watching the moon that is. Note how it moves across the sky. What kind of path does it take as it move?

Make sure you have a clear view and have chosen a place that has two large, unmovable landmarks where the moon makes its path across the sky. The two objects should be a short distance more than the width of your hand apart form each other. Two trees or telephone poles work very nicely.

Use a stopwatch to time the moon as it travels across the sky from one landmark to the other. Make sure to write down the time so you can use it later.

Repeat this experiment several more times. It's best to repeat the experiment during the same phase of the moon each time. But don't worry if you miss a day here or there. All you need are about ten days of numbers to make this work. The more, the better!

Process Data

It's time to organize what you've discovered. Take all the numbers from each day and average them (add them up and divide by the number of days.)

Now copy all your times neatly in a finalized form onto a graph or chart.

If you're not sure how to graph and chart click here.

Here's a generic graph to give you a little bit of an idea what it should look like. Remember...

It needs to be neat!

Make sure to note the highest and lowest times. Also note the most consistent occurring results.


It's time to tell what you've noticed. Astronomy science fair projects are just experiments without a report. So, we'll write a report about what you saw.

You should include...

1. What you guessed about the moon telling time.
2. What you did as you observed what the moon did.
3. If your guess was correct about how the basketballs bounced.

Be careful to obey all the school rules for your science fair report. One paragraph for each of your grade levels will do if you weren't given how long it should be. Be detailed as well. But make it neat.

Let's go to the final step...


Now you get to make the display!

Carefully put three pieces of cardboard together so it looks like this...

If you want more information about how to put together and arrange displays click here.

You can buy displays at many retail stores as well. However you do it, make sure you follow science fair rules!

Now, on a piece of paper neatly write your important question and your guess. If you would like, type it. You might get style points!

Now, just like you did your important question, write (or type) your supply list on a separate piece of paper.

Paste your guess, supply list and report onto your display board along with any pictures you might have taken. Make sure you label each so the judges know what is what. Making sure everything looks good is important!

Try playing with some of the display ideas you see. You don't have to use the exact ones we use. Make them fun! Be creative!

And don't forget to name your astronomy science fair project at the top of the display board. It's best to use your important question as the title. You may want to purchase stencils to make cutouts of letters. Or you may purchase already made letters at many retail stores.

So don't just sky gaze...make your nighttime visits into great astronomy science fair projects. And...most of all...

Have fun!
