       (tops, gyroscopes, pinwheels, windmills, globes, or maple seed)? Teacher demonstrates these if
       possible. Students record their prior knowledge in a science notebook, share and discuss.
    Formative assessment is outlined in the instruction plan below
    Post-assessment: Students prepare an oral presentation for the class that communicates: predictions,
       design, and results of the investigation and make conclusions regarding the variables affecting the
       motion of the Bugs-O-Copters. Provide a rubric for evaluating the presentation based on the learning
       targets.

                            Instruction and Formative Assessment Plan
Materials/Resources Needed:                            Scissors
   1 short-eared Bugs-O-Copter                        Several small and large and small paper clips
   1 long-eared Bugs-O-Copter                         Assorted materials based upon student
                                                         designed investigations.

                               Learning Activity                               Formative Assessment (Formal & Informal)
Background: Gravity naturally causes the Bugs-O-Copter to fall to the
ground; however as the Bugs-O-Copter falls, the air pushes up against
the ears. The angle of the ears causes the air to move sideways, causing
a simple thrusting motion. As the air molecules hit the underside of the
ears, this causes a small amount of friction, counteracting the rate of fall
caused by gravity. The larger the surface area of the ears, the more
friction will occur, and the slower the Bugs-O-Copter will spin or fall.
Students will design ways to change the aerodynamics of the Bugs-O-
Copter by changing the shape or size of each of the ears or changing the
amount or position of the paper clip. In this activity students move very
quickly through phases of the investigation. In seconds, they move from
the "questions" phase to the "implementation" phase. The intermediate
steps of identifying the manipulated and the responding variables often
occur without the student consciously thinking about them as important
features. The teacher should facilitate students' becoming aware of their
thinking process.

Misconceptions: Students often associate how the Bugs-O-Copter works
with how an actual helicopter works. Be sure to clarify the difference at
the end of the lesson.

Students will work individually as they progress through the following
stages;

Engage: Assess prior knowledge by posing the question, What do you             Formal: Students record their prior

                                                                               to prior knowledge about air, friction,

Questions may include the following:                                         to plan appropriate scientific investigations.
      Does the number of paper clips affect the falling rate?               Students may be given a predetermined

         Bugs-O-Copter?                                                      by which to evaluate their own investigation
      Does the thickness of the paper affect how the Bugs-O-Copter          plan.
         will spin?
      What would happen if I made a Bugs-O-Copter out of poster-
         board instead of paper? What if I put the paper clips in a
         different location?
      How can I get both the short-eared and long-eared Bugs-O-
         Copters to hit the floor at the same time?
      What if I change the direction the ears are folded?
      How would cutting slits in the ears affect the spinning?
      Will the way the ears are folded affect how the Bugs-O-Copter
         will spin?
      How can I make the Bugs-O-Copter spin in the opposite
         direction?
      Which Bugs-O-Copter makes more spins before hitting the floor?
      What if I cut out the outline (shape) of the ears?
      Does the shape of the ears affect how the Bugs-O-Copter falls?

Evaluate: Students prepare an oral presentation for the class that
communicates: predictions, design, and results of the investigation and
make conclusions regarding the variables affecting the motion of the
Bugs-O-Copters. Provide a rubric for evaluating the presentation based
on the learning targets.
