Warmup: (Far Side)

1) Turn in your permission forms to the yellow box in front of the room.

2) Open up to “Paper Platforms.”3) The next section is “Evaluate the Criteria.”

Learning target:

• With my team, we will COLLABORATE and RECORD in our journals the rest of the Paper Platform experiment.

Announcements:

• FT this Friday. Dress warmly and you will walk in the dirt some.

• Go to your first period class.

• First vocabulary quiz next Monday – notecards for extra credit

Warning:

Most people go to science fair thinking they have worked HARD.Everyone returns from science fair wishing they worked HARDER.Your classmates are NOT your standard.

Up to now we have done part 1

• Draw a line – mark it – time for part 2

2) Generating Possible Solutions

• Identifying Criteria: Describe the rules and how you will know if you are successful.

• The plane can only be made of paper and simple classroom materials. It must be flown in the classroom and land in a 2’ x 2’ x 1’ high cardboard box. The box is placed 20 feet from the throwing line.

• Define and Describe Possible Solutions: List possibilities that you are considering.

• The Dart, The Bulldog, and the Classic Arrow designs from the web.• Select a solution and explain why: Which design do you believe is the

best and explain why. List all of the ideas that you are considering right now that you think might work.

• We will try the Bulldog because after building and throwing each of the three, we were clearly able to control where the Bulldog landed more than the others.

Criteria

• Lowest part of the book 10 cm off table• Use only 1 sheet of 8 ½ x 11 inch paper and

less than 12” of clear tape.’• 1 large book

Describe and Define Possible Solutions

• Pick three structures or variations that you want to try:

• A) Totally different• B) # of structures• C) Different shapes• D) Different diameters

At your table, choose which one will work the best.

• We believe that the ____________ will support the most mass because ___________________________.

2) Generating Possible Solutions

• Procedure:• Material list – simply list all of the materials you

will use for this experiment• Diagram – included a LABELED diagram of what

models you are testing• Step by step – include in detail how you will test

the results. Who – what – where – etc.• Data Table – a good table to help organize your

collection of data.

Testing Procedure

• 1) Build Structure• 2) Add science text book• 3) Measure distance from the lowest part to

the table• 4) Add a text book• 5) Continue to do so until structure fails or

lowest part is under 10 cm• 6) Write observations

End of Part 2

• Draw a line – mark it – time for part 3

Break

• Stand and stretch while you learn about the fall solstice.

3) Collecting and Presenting Data

A) Filled out data tableB) Create a graph of your results

End of Part 3

• Draw a line – mark it – time for part 4

4) Analyzing and Interpreting Results

• Problems and Solutions: List the problems that you had while collecting data and how you solved them if you did.

• Wind kept causing planes to fly off course – moved setup to a closed classroom.

• Data: Which modification worked best. How do you know?• The clipped wings (5) and construction paper (4) both seemed to

provide the most accuracy, but not by much over the regular design (3).

• Future Investigations: Describe a future experiment that could be done based on what you have learned.

• The above experiment can be done, eliminating the paperclipped nose, with more trials and then mixing and matching the proposed modifications to see how they work together.

Problems and Solutions

• Problems building and/ or testing the structures:

Data

• The _____ structure worked best because _____________________.

Future Investigations

• Three investigations based on what you have learned.
