Hacer un álbum de recortes incluyendo lo siguiente:

a. Fotografías, tarjetas postales o dibujos de 25 faros. Las etiquetas deben incluir una breve descripción de: localización, año de construcción, estatus activo/no activo y orden del lente.

b. Escribir una breve historia de los faros anteriores.

c. Incluir dibujos/fotografías y respuestas de todos los requisitos para esta especialidad en su álbum de recortes.

3

Hacer una lista del desarrollo de una lente de Fresnel, que incluya:

a. Nombre del señor que lo inventó

b. País de donde ha venido

c. Año desarrollado.

Augustin-Jean Fresnel

3a) Name of the gentleman that invented it: Augustin-Jean Fresnel (pronounced fray-NELL) is most often given credit for the development of this lens for use in lighthouses.

4

Dibujar un lente de Fresnel:

a. Mostrar cómo los prismas se utilizan para concentrar la luz

b. Mencionar su propósito

• http://science.howstuffworks.com/question244.htm (External link on how a Fresnel Lens works)
• http://www.lanternroom.com/misc/freslens.htm (Look at figure #3 for how the prisms/bull's eye reflect light)

5

Hacer un gráfico que muestre cada clase de lente de Fresnel:

You can get a nice diagram/chart at the Library of Congress.

5a

Definir el orden y hacer una lista por tamaño

5b

Nombrar al menos un faro utilizando cada orden

6

Investigar y describir la historia de los mecanismos de rotación de las luces.

In early years and the lenses were rotated by a weight driven clockwork assembly wound by lighthouse keepers (sometimes as often as every two hours). The lens assembly usually floated in mercury to reduce friction. In more modern lighthouses, electric lights and motor drives were used, generally powered by diesel electric generators. These also supplied electricity for the lighthouse keepers.

Hacer un gráfico que muestre la firma de 6 faros de noche (luz) y durante el día (marca de día).

Daymark

Lighthouses have distinguishing daymarks. No two lighthouses are exactly alike. This way, ships and sailors can determine their location. For example, if you see a red lantern and black and white spiral stripes, you will know that you are off the coast of St. Augustine.

• 

  Alcatraz Island Lighthouse
  Natural color with black lantern with Octagonal/Pyramidal tower.

• 

  Point Loma Light
  Square Pyramidal (skeletal).

• 

  Fourteen Foot Bank Light
  Cast Iron (Square)

• 

  Alligator Reef Light
  White octagonal pyramid on black skeleton tower.

• 

  St. Augustine Light
  Conical tower, red lantern and black and white spiral stripes

• 

  Thomas Point Shoal Light
  Square on hexagonal house, White with Red Roof and Black Lantern.

• 

  Holland Harbor Light
  Wood, Square, Red.

• 

  Cape Hatteras Light
  Conical, white and black spiral bands with red brick base.

Nightmark

In similar fashion, the signature or pattern of light at night is the nightmark. By viewing this distinctive signature, sailors can tell their location even in the dark.

• Pigeon Point Light Station: Flashing white 10s
• Point Bonita Lighthouse: Occulting white once every 4s
• Ponce de Leon Inlet Light: fixed light (original)
• Cape Hatteras Light: Short flash every 7.5 seconds
• Au Sable Light: Flashing white every 6 s
• Fort Washington Light: flashing red

¿Qué es un buque faro? ¿Por qué y dónde se necesitan los buques faros?

Ambrose Lightship

A lightship is a lighthouse on a ship. It allows a lighthouse to be put where a lighthouse cannot be built. For example, a lightship may be moored over treacherous reefs, or marking the narrow approaches to a channel. Also, at harbor entrance(s) where lighthouses can not be built or placed in areas too far offshore for a land-based lighthouse's lens to reach.

Leer sobre los mantenedores de los faros y hacer una lista de algunos de los peligros que se enfrentan al completar sus tareas.

A lighthouse keeper is the person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms where used. Keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows.

Many lighthouse keepers lived in isolated locations. The isolation could cause mental health issues. In a medical emergency they could be far from help. They had to climb towers and could fall. They also served as first responders to shipwrecks in storms which could be dangerous. Traveling over the ocean to and from work also had its hazards.

10

Estudiar citas de Elena G. de White que mencionan a los faros y discutir el significado. Colocar una copia de las citas en su álbum de recortes.

Here's a link to a quote: http://www.whiteestate.org/issues/Drama.html. See pages 6, 17, 18.

Whiteestate.org has a searchable database of Ellen White's writings. Type in lighthouse and see what you find.

Obtener un «pasaporte de faros» y tenerlo sellado de 10 diferentes lugares de faros.

• Lighthouse Passports
• Participating Lighthouses

12

Construir un modelo de faro de un faro verdadero utilizando un kit de faro de madera u otro medio. Conocer el nombre, la ubicación y la fecha en la que el faro real fue constituido originalmente.

Have Fun! You should have no problems finding a kit to build on the Internet.
