Now through next Tuesday in Science!

Students have completed story boards and are now into filming.  The premise of this project is to apply their knowledge of life cycles in creating a scary movie!  Through this process, students will be able to show proficiency of a variety of standards.  Those standards will populate the grade book in the next two weeks. These standards include:

Understanding Life Cycles
Understanding Types of Reproduction in Pond Ecosystems
Understanding and Identifying Organisms in Pond Ecosystems

I have been so pleased with the work of these kids!

Out ahead we will begin a short three week study on the role that cells play in the functions of living things.

Tuesday Second Hour....Airplane Design Challenge

Instructions:

Each student will the following materials...

  • Four Pieces of Paper
  • Four Staples
  • Three Drops of Glue....On their Honor....
  • 3" of masking tape
  • NO SCISSORS OR CUTTING!!!  torn paper is fine...
  • Fold n' Fly Website
Students will design their two best airplanes.  They may choose to make the planes out of one or two pieces of paper.  Below are the rules and research article.  Have students pick up material after they have read this blog entry.  Students will design, create, and test in the room today.  Tomorrow they will be judged on distance as well as time in flight to determine the champion.  


Aerodynamics

What makes a paper airplane fly? Air — the stuff that's all around you. Hold your hand in front of your body with your palm facing sideways so that your thumb is on top and your pinkie is facing the floor. Swing your hand back and forth. Do you feel the air? Now turn your palm so it is parallel to the ground and swing it back and forth again, like you're slicing it through the air. You can still feel the air, but your hand is able to move through it more smoothly than when your hand was turned up at a right angle. How easily an airplane moves through the air, or its aerodynamics, is the first consideration in making an airplane fly for a long distance.

Drag and Gravity

Planes that push a lot of air, like your hand did when it was facing the side, are said to have a lot of "drag," or resistance, to moving through the air. If you want your plane to fly as far as possible, you want a plane with as little drag as possible. A second force that planes need to overcome is "gravity." You need to keep your plane's weight to a minimum to help fight against gravity's pull to the ground.

Thrust and Lift

"Thrust" and "lift" are two other forces that help your plane make a long flight. Thrust is the forward movement of the plane. The initial thrust comes from the muscles of the "pilot" as the paper airplane is launched. After this, paper airplanes are really gliders, converting altitude to forward motion. Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is this difference in pressure that enables the plane to fly. Pressure can be reduced on a wing's surface by making the air move over it more quickly. The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing.

The Four Forces in Balance

A long flight occurs when these four forces — drag, gravity, thrust, and lift — are balanced. Some planes (like darts) are meant to be thrown with a lot of force. Because darts don't have a lot of drag and lift, they depend on extra thrust to overcome gravity. Long distance fliers are often built with this same design. Planes that are built to spend a long time in the air usually have a lot of lift but little thrust. These planes fly a slow and gentle flight.



Monday and Tuesday Science

Today in science we are doing individual research on the types of organisms we might highlight in the upcoming video feature.  We are completing the 4 C's activity to support this.



Objective: Discover critical information that helps you determine what creatures to highlight in your future movie.
Task: Research and document the following items about a chosen organism that could live in a Michigan Pond ecosystem.
  • Challenges: What challenges does this organism deal with throughout it’s life cycle?
  • Connections: What connections does this organism have with other organisms?
  • Character: What does this organism look like and act like at each stage of it’s life cycle?
  • Components: What does this organism need to survive at each stage of it’s life cycle?

Procedure:
  1. Document name of organism on back of sheet.
  2. Document website address for information collected in space below.
  3. Document information on back of sheet.
