Do you know what condensation is? More than likely you've seen it some time in your life. Yeah, really! This experiment will prove it to you. Let's find out about condensation...
Time - Give yourself about one week to do this one.
1. Lot's of ice cubes
2. Five (5) jars
3. Five (5) bowls
4. Measuring cup
7. Cardboard for display (order here from Amazon)
8. Graph paper
9. Pencil and paper
11. Computer (optional)
With any thing that has to do with science, it's always important to ask questions. Science fair projects are no exception. So...
...let's ask some questions.
Here are some important questions to get you started. These aren't the most important question, though. We'll ask that one later.
See if you can add to this list for this condensation project.
What is condensation?
Have you ever seen water condense?
What is the water cycle?
Try to answer these as best you can. Ask you parents if you don't know. They know a lot. Also, have them help you find information to answer each of these questions. Check your local library, encyclopedias or the internet.
We ask the most important question...
Does the amount of ice in a container affect the amount of condensation produced?
This is a good question because we can try it out in our kitchen. 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 experiment 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.
Now comes the fun part...
...let's experiment! Place each jar in a bowl. Fill one jar completely full with ice. Repeat this with each glass filling the next on 3/4 full, then 1/2 full, then 1/4 full. Leave the last jar empty. It should look something like this...
Set your timer for one hour. After the hour is up remove the jar being careful not to spill any water from the jar. Wipe the jar clean before removing it from the bowl.
Check the water in the first bowl by pouring it into a measuring cup. Do the same for each bowl of water.
Only measure the amount of water in the bowl. The water in the jars don't count. So don't spill any. That'll ruin the project.
Here's how it should look...
Make sure you write down the amount of water in each bowl on a piece of paper.
And don't forget to take lots of pictures of this part. Pictures show you did your own work.
Set the project up again and set your timer for one hour. Repeat the project until all the ice is melted. It's important that you do this condensation project several times. Each time...
Be careful when you measure!
...let's make the graph!
Take your graph paper and put "1 tsp," "2 tsp," "3 tsp" and so on going up the paper. These will stand for the amount of water you noticed from each bowl.
Now write labels along the bottom that say "Empty," "1/4," "1/2," "3/4" and "Full" at the bottom. These stand for each bowl.
Fill it in with the information you put on your paper when you did the experiment. Make one graph for each time you did your experiment. It should look something like this...
If you're still not sure about making your graph, click here for more information about making winning charts and graphs.
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 amount of condensation.
2. What you did with the jars bowls.
3. Which bowl had the most.
4. If your guess was correct about the bowls.
Be careful to obey all the school rules for your science fair report. One or two paragraphs for each 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 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!
If you want to get some ideas for your display we have some examples for you. Just click here for examples of experiment displays that you might want to use for your condensation experiment.
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...
Learn everything you can...
Do the best you can...
And most of all...
Have fun with your condensation experiment!
