Food science fair projects can teach us a lot!

Food science fair projects let you play with your food with your parent's permission! What a deal! But of course we will learn

something as well. So...

...let's play with our food!

Time - Give yourself about three to four weeks to do this one.

Stuff List

You'll need...

1. Loaf of bread
2. Fold top plastic bags (store and name brand)
3. Zipper top plastic bags (store and name brand)
4. Aluminum foil
5. Plastic wrap
6. Wax paper
7. Graph paper
8. Camera
9. Cardboard for display (three sided)
10. Glue
11. Paper
12. Something to color with
13. Computer (optional)


Preparation

It's always important to ask questions. In food science fair projects it's important too. Because we use bread and wrapping materials for this one...

...let's ask a question about wrapping sandwiches. But first...

Let's do some research. Ask a grandparent or someone older how they wrapped sandwiches when they were younger. Did they use the same materials then that they do now?

Observe some of the kids in your lunch room. What kind of things are their sandwiches wrapped in?

Write down some of the things you've observed.

Now...

We ask the most important question...

Which method of wrapping a sandwich is best?

This is a good question because we can try it out in your mom's kitchen to see what happens...

With your mother's permission first of course!

But don't try it yet. We need to answer our important question first!

Let's do that now.

What do you think the answer is to your important question?

Write your guess down on a piece of paper. Don't change it until you see what the fruit does first. We call this guess our hypothesis.

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

Project

...Let's try our hand at food science fair experiments!

Wrap one piece of bread in each kind of wrapping material. Make sure not to damage the bread as you put it in. Also, make sure each sandwich is properly wrapped or sealed. Then put one unwrapped piece with the wrapped ones. Place each one on a shelf or tray something like this...



We call this the control group.

Don't forget to take lots of pictures of you wrapping the sandwiches. Pictures show you did your own work.

Each day check for changes to the different pieces of bread. Mark them down on a chart that tells you what materials you used and how much each on costs. Your chart should look something like this...

Chart!



To figure the price of each wrapping, take a calculator and put the total price of the box of wrapping and divide that by how many bags or feet came in the box. If you don't know how to do that, ask your parents to help you with the calculation.

Paper

...let's make the graph!

Make one that shows th prices and another that shows freshness. Your graph should look like this...

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 sandwiches.
2. What you did with the sandwiches.
3. What happened to each sandwich.
4. If your guess was correct about the sandwiches.

Be careful to obey all the school rules for your science fair report. One or two paragraphs per grade level will do if you weren't given how long it should be.

Presentation

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 that go great with food science fair projects 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 hypothesis (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 might fit food science fair projects. Try playing with some of the display ideas you see. Not all of them will work with food science fair projects. So be careful about what you choose.

You don't have to use the exact same ones we use either. 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 food science fair projects!
