Imagine It! Build It! Fly It!

Type of Kite!

The Kite I have picked is a Della Porta kite for the Quad D project. The della porta kite has a rectangular shape.

Blue Print

My blueprint was created in paint shop. In this blueprint it tells me what the finished kite in science will look like and the measurements of my materials.

Dowels: 91cm

Trash bag (height): 97cm

Trash bag (base): 73cm

Math Problem #1

PROBLEM ONE: In 1820, George Pocock connected several large kites to a carriage and pulled it from Southampton to London. Since road taxes were based on the number of horses used to pull a carriage, he was able to avoid any taxes! The 60 mile trip took two hours. Modern kite buggies now go twice as fast but seldom go as far. How fast was the carriage moving?

Answer to Math Problem #1

The answer to problem #1 is 30mph. I got this because the trip was 60 miles long total and it took 2 hours. I divided 60 by 2 and got 30.

Math Problem #4

PROBLEM FOUR: The largest kites built in Japan are flown in Hoshubana every May. The kites are 36 feet wide and 48 feet tall with bridle lines more than 100 feet long. It takes fifty members of the O-dako (Giant Kite) Association of Hoshubana to launch this giant creation. Each team member is suitably uniformed in a traditional festival jacket that matches the kite. The kite is made from individual pieces of rice paper, each glued together at the edges. If each sheet is 18 inches wide and 24 inches tall, how many sheets are needed to create the sail of this Japanese kite?

Answer to math problem #4

Size of the rice paper: 18 in. x 24 in.

18 inches = 1.5 feet

24 inches = 2 feet

size of rice paper (converted to feet like the kite): 1.5 ft. x 2 ft.

area of rice paper in feet: 1.5 ft. X 2 ft. = 3 ft. sq.

Size of the kite: 36 ft. x 48 ft.

area of kite: 36 ft. X 48 ft. = 1728 ft. sq.

Amount of rice paper to construct kite

area of kite divided by area of paper in same units (feet)

1728 ft. sq/kite divided by 3 ft. sq./rice paper = 576 rice paper/kite

ANSWER: 576 rice papers are needed.

Note: Since the height to width ratio are the same for the rice paper and the kite; and since both the height & the width of the kite are equally divisible by the respective height & width of the rice paper, then the kite builders will be able to use all whole sheets of rice paper with no partial sheets remaining - and no cutting of the paper!

Surface Area!

The surface area of my kite in science was 7,081cmsq.

97cm x 73cm = 7081cmsq.

My kite was a rectangle so I had a formula (b x h) to get the answer. Since my kite had this formula I did not need to decompose my kite.

Creating Model

Creating a model of the kite in math really helped because when I got to science class I knew how to build the kite the right way. Also it helped because I knew how to attach the bridle line, and I also knew what the kite was going to look like.

Finished Kite!

This is a picture of the completed kite I have created with Emma Dlhosh and Claire Vance.
