Workshop: Scientific Process

Today's workshop is about scientific process: We will follow the steps of the scientific process to achieve our goal.

Today's goal for our experiments is to design a paper airplane that will fly the farthest. We will be allowed 3 variables to use alone and in combinations to test our designs.

To do this we will follow the steps of the scientific
process

Remember, the steps of the scientific process are the following

Steps of the Scientific Process

1.Identify the Problem

2.Gather information

3.Form Hypothesis

4.Test the Hypothesis

5.Record observations, collect data

6.Organize and analyze the data

7.State a conclusion: did we prove or disprove your hypothesis

_______________________________________________________________________________

Step 1: Identify the Problem:

What is it you need to prove or disprove? State it clearly as a question!

What factors will make a paper airplane fly the farthest?

We will have 3 different design variables that you may
add to your airplane to make it fly farther.

You can only add them one-at-a-time!

- You may change the shape of the airplane by the way you fold the wings. Can you make a design that will fly farther by just folding?
- You may add three large paperclips anywhere on your airplane to give it more weight to make it fly farther. You may use less but NO MORE THAN THREE PAPERCLIPS.
- You may add one penny to your airplane anywhere to give it critical weight to make it fly farther. It is your choice where you add the penny to the airplane.

Step 2: Gather information:

take 10 minutes and look on the internet; has anyone tried this experiment before?
What were their results?

________________________________________________________________________________________________________

Step 3: Form a hypothesis

Make a prediction!

Which single factor alone will make the airplane fly the farthest?

The shape changes you add?

The extra weight from the paperclips added?

The extra weight from the penny you add?

What is your prediction?

I think the airplane with the paperclips will fly the farthest because I can
put the weight exactly where I want it is a prediction.

What is your hypothesis?

Adding paperclips to a paper airplane's nose will make it fly farther than a
regular airplane is a hypothesis!

________________________________________________________________________________________________________

Step 4: Test the Hypothesis:

We will perform a scientific experiment to see if our predictions are accurate!

We will take our airplanes to the gym downstairs to do our tests indoors in
a controlled environment

We will start with our normal airplane
with no changes that we will use as our control
group

A control group is a group that has no special treatments
or changes.

We will put out a tape measure and we will see how far our control group plane
can fly! This is our airplane before we make any changes.

We will than change our first independent variable the paperclips! We will fly our airplanes and see how much farther they go and measure the distance.

_______________________________________________________________________________________________________

Step 5: Record our observations: collect

data:

We will record our results after trying three times and taking the average
of our results

This answer is our first dependant variable!

We will than try out our second independent variable:
adding the penny!

We will again fly our airplanes 3 times, record the distance and measure the
results. We will

again take the average of our three tries to determine our distance. Did it
go farther than a regular airplane? Did

it go farther than the one with paperclips?

This answer is our second dependant variable!

We will now try out our third independent variable variable.

You may refold your airplane into any design you want but you may not use the
paperclips

or penny!

How far can you make the airplane go just by the shape you refold it into?

This answer is our third dependant variable!

The airplane we test first with no changes is our control group.

The airplanes that we add a variable to each time are the experimental groups.

The factor we change each time (the addition of weight or shape) is the independent variable.

How far the plane goes with each change, what we are measuring to test our predictions, is called the dependant variable.

The records we make measuring the distance of each of our flights is our observations.

The distances we write down of how far each flight goes is our data.

Step 6: Organize our data we recorded:

The next to last step is to plot our data on a graph and see which airplane
design actually went the farthest.

This is the organization and analyzation of our data.

Step 7: State our conclusions! Did we prove
or disprove our hypothesis?

Our final step is to look at our data and see if it proves our hypothesis?

Did our prediction come true? Was the hypothesis you made at the start correct?
