Skimmer+Project


 * Skimmer Measuring Activity **
 * Experience fractions

In this activity you will create a skimmer that will slide across the floor with ease if your measurements are accurate and your workmanship is exceptional.
 * Equipment **
 * Pencil
 * English ruler
 * 60# Cardstock, Tagboard, file folder, or cereal box
 * Glue
 * Tape
 * (Paper clip optional)
 * Procedure **

 
 * 1) Neatly and accurately use the plan sheet and measuring tool to draw your skimmer main body, air scoop, and two (2) fins onto the material that you will use to make your skimmer.
 * 2) Carefully cut out your skimmer parts. Cut only on the solid lines. The dotted lines are where you will score and fold.
 * 3) Use your ruler to draw the dotted lines on your cardboard air scoop and main body, and then fold on these lines to create a 90° angle.
 * 4) <span style="font-family: Arial,sans-serif; font-size: 12pt;">The material that you use should fold easily and hold its shape. Decorate your air racer before assembling.
 * 5) <span style="font-family: Arial,sans-serif; font-size: 12pt;">Glue the fins to the ½ in. flap on the main body. Make sure that the angled edge faces the front of your skimmer. Glue or tape the main body back to the fins at an angle as shown in the orthographic drawing.
 * 6) <span style="font-family: Arial,sans-serif; font-size: 12pt;">Glue the flaps of the air scoop to the inside edges of the main body with the narrow end flush with the front of the main body as shown in the orthographic drawing.
 * 7) <span style="font-family: Arial,sans-serif; font-size: 12pt;">After all glue has dried, throw your skimmer along the floor and see how smoothly it glides.
 * 8) <span style="font-family: Arial,sans-serif; font-size: 12pt;">You may want to put a paper fastener behind the air scoop and use a rubber band to propel your skimmer across the floor.
