Design and Fly a Kite Pre

When flying a kite, which of the following best describes the forces you need to consider?

• The force of gravity pulling it downwards, the tension in the string pulling it upwards, and the wind pushing it sideways.

• The force of gravity pulling it upwards, the tension in the string pulling it downwards, and the wind pushing it sideways.

• The force of gravity pulling it sideways, the tension in the string pulling it upwards, and the wind pushing it downwards.

• The force of gravity pulling it downwards, the tension in the string pulling it sideways, and the wind pushing it upwards.

To successfully fly a kite, one must:

• test and validate wind conditions

• increase the weight of the kite

• delay the launch until the wind stops

• reduce the length of the string

The process of flying a kite involves several steps. Which of the following is the correct sequence of these steps?

• Identify the location, assemble the kite, launch the kite, control the kite, land the kite

• Assemble the kite, identify the location, control the kite, launch the kite, land the kite

• Launch the kite, identify the location, assemble the kite, control the kite, land the kite

• Control the kite, identify the location, assemble the kite, launch the kite, land the kite

Match the word to its definition by connecting them with lines.

• Force that opposes the motion of an object traveling through fluid.

• force

• A force, opposite to gravitational force, created by fluid (air) flowing past an object.

• drag

• A three-dimensional shape made of four equilateral triangles.

• tetrahedron

• The act of pushing, pulling or applying pressure.

• lift

• A system (such as a kite) that consists of multiple subunits that complete the whole design.

• modular

Run fast with the kite in the air. Let go of the kite. Hold onto the string.

What happens next?

• The kite will fall down.

• The kite will fly up with the wind.

• You will fall down.

• Nothing.

You should run slow with the kite in the air.

• True

• False

If the wind does not catch the kite, __________ __________!

• give up

• run away

• eat pizza

• try again

You need __________ to fly a kite.

• nothing

• food

• wind

• water

Which of the following is true?

• Kites were invented long ago. They have provided help and entertainment to people throughout the years.

• Kites are an important tool in history. The most famous kite flying experiment was performed by Benjamin Franklin in 1752. He wanted to prove that lightning was made of electricity.

• Kites were used in World War II. The Navy wanted the kites to tangle up the propellers in enemy planes. Today people “battle” at kite-flying contests.

• Kites have carried weather instruments to help meteorologists. Today people fly kites at festivals around the world.

What happened as a result of military airplanes becoming more popular during wars?

• Battles are fought only between kites at festivals.

• Scientists used kites more often to learn about weather and the atmosphere.

• Kites were used less to help soldiers beat the enemy.

• Kite design moved from bigger and bulkier to smaller and sleeker
