This science fair project water experiment is bound to make waves! You will learn about what water does when it is frozen. So...
...jump right in. The water's great!
Time - Give yourself about three or four days to do this one.
1. Two types of water (fresh and salt water work great!)
4. Measuring cup
7. Cardboard for display (three sided)
10. Computer (optional)
It's always important to ask questions. In science it's even more important. So...
...let's ask some questions about water.
Here are some important questions to get you started. These aren't your most important question, though. We'll ask the big question later.
See if you can add to this list for this science fair project water experiment.
What is water used for?
How can we get it?
How is all wate alike?
What are some ways different types of water are different?
Try to answer these as best you can.
We ask the most important question...
Which water freezes faster?
This is a good question because we can try it out in a freezer at home. But don't try it yet. We need to answer our important question first!
Let's do that now.
What do you think will happen?
Write it down on a piece of paper. Don't change it until you see what the water in the freezer does first. We call this guess our hypothesis.
Now it's time to get your stuff from the list above. Let's move to the next step.
...let's do this science fair project water experiment! Get your two types of water. Salt water and fresh work the best. With the measuring cup, put the same exact amount of water in both cups. Be careful at this point. Putting different amounts of water in the cups could ruin the experiment.
It should look like this...
Carefully label the cups. You may want to label them with numbers. Now make a chart that looks something like this...
Set the cups in the freezer. Every hour check the water and what it does, and write down what you notice. Don't forget to take lots of pictures of this part. Pictures show you did your own work.
You may want to use your mom's kitchen timer (ask first!) to help you keep track of the time. Be faithful to check your cups every hour.
And don't forget to write down what you see!
...let's make the graph!
Make a graph using the information you put on your chart. Don't forget...
Judges like graphs. So here's an idea for your graph of this project...
It's time to tell what you've noticed. Write a report about what you saw.
You should include...
1. What you guessed about the two kinds of water.
2. What you did with the water.
3. Which water froze faster, salt or fresh water.
4. If your guess was correct about the two types of water.
Be careful to obey all the school rules for your science fair project water report. Two paragraphs per grade level will do if you weren't given how long it should be.
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 displays and other tips and hints click here. You can also 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!
If you want to get some ideas for your display we have some examples for you. Just

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 project at the top of the display board. You may want 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.
Whatever you do, have fun with your science fair project water experiment!
