Discuss with the children the concept of drag in relationship to a
sailboat.
|
|
Have each child make a sailboat. Have each of them draw a boat shape
on the Styrofoam tray with a pen.
|
|
Cut the boat shape out of the Styrofoam tray.
|
|
Make the sails out of the clean sheets for the children. Give each
child a sail with the wooden skewer already through the sail. To insert
the wooden skewer easily make two small holes in the sheet sail in two
places to slip the skewer through.
|
|
|
|
Have the children put the sail on the Styrofoam boat.
|
|
Taking turns, have the children put their boat in the water. Teacher
- Turn on the fan for the child. Two boats can be put in the water at
the same time to see if they move at different speeds by the same amount
of 'wind' created by the fan.
|
|
Talk together as a class about how drag from the sail affects the
sailboat.
