  • Hazards Moving around in the Dark

    Use a flashlight with a red filter Check out the area in the daylight

    Protect your Eyes Never look directly at or near the sun

    Weather Wear warm clothes if it is cold Use sunscreen if observing during the day (e.g. sun spots or a

    solar eclipse) Drink plenty of liquids if it is hot (avoid dehydration) Use insect repellant if there are biting or stinging insects in the

    area

  • Fill in Part 1a

    Explain to your counselor the most likely hazards you may encounter while participating in astronomy activities, and what you should do to anticipate, help prevent, mitigate, and respond to these hazards. Hazards: Tripping over something in the dark, looking at the sun, _________________ weather and insects ______________________________________________ _______________________________________________________________ _______________________________________________________________

    What you should do: Use a flashlight with a red filter, look around the area in the daylight to see__ what you might trip over, never look directly at the sun, wear warm clothes if it is cold, use sunscreen if the sun is bright, use insect repellant if there are__ biting or stinging insects.___________________________________________ _______________________________________________________________

  • Review First Aid

    Heat Reactions (heatstroke) Cool the victim immediately Face up with head and shoulders raised Remove outer clothing Wet skin/underclothing with cool water Apply cold packs, use a fan, or place victim in a tub of

    cool water Obtain medical help as quickly as possible

    Cold Reactions (hypothermia) Actively warm the victims body If needed, use your (and others) body heat Obtain medical help as quickly as possible

  • Review Fist Aid (continued) Dehydration

    Drink 2 quarts of rehydration drinks, water, juice, or sports drinks in 2 to 4 hours

    If victim if conscious but cannot drink, try ice chips Obtain medical help as quickly as possible

    Bites and Stings Do not scratch (avoid infection) Apply ointment if needed Tick bite - cover them with a thick substance that will

    cut off their air supply, be careful to remove the whole tick

    Damage to Your Eyes Cover eyes Obtain medical help as quickly as possible

  • Fill in Part 1b Explain first aid for injuries or illnesses such as heat and cold reactions, dehydration, bites and stings, and damage to your eyes that could occur during observation.

    Heat reactions:

    Cool victim, make sure they are lying face up, remove unneeded clothing, wet skin, apply cool packs, get help (911)___________________________________________________ ________

    Cold reactions:

    Actively warm the victims body, get help (911)______________________________________

    ____________________________________________________________________________

    Dehydration:

    Drink 2 quarts or try ice chips is unconscious, get help (911)____________________________

    ____________________________________________________________________________

    Bites and stings:

    Do not scratch, apply ointment, for tick bite cover them with a thick substance that will_____ suffocate them_________ _______________________________________________________

    Damage to your eyes:

    Cover victims eyes, get help (911)__________________________________________________

  • Observing Objects Near the Sun

    Some planets always appear to be near the sun when viewed from the earth

    Only look for these planets (Mercury, Venus) after the sun has completely set

    The new moon is also seen near the sun

    Do not look for it until the sun has disappeared from view

  • Fill in Part 1c

    Describe the proper clothing and other precautions for safely making observations at night and in cold weather. Night: Wear closed-toe shoes so you dont bump your toes in the dark, bug spray for mosquitos______________________ ______________________________________________________________________________________________ Cold Weather: Wear layers with gloves and a warm cap_____________________________________________________________ ______________________________________________________________________________________________ Then explain how to safely observe the Sun, objects near the Sun, and the Moon. The planet Mercury and the new moon are close to the sun at sunset or sun rise, dont look for them unless the___ sun is completely below the horizon_________________________________________________________________ ______________________________________________________________________________________________ ______________________________________________________________________________________________ ______________________________________________________________________________________________ ______________________________________________________________________________________________ ______________________________________________________________________________________________

  • Light and Air Pollution (2)

    Light pollution is caused by too much artificial light illuminating the night sky

    It prevents you from seeing dim stars and planets

    It ruins your night vision

    Air pollution can also obscure dim objects

    Haze (high humidity)

    Dust

    Chemical air pollution

  • Fill in Part 2 Explain what light pollution is and how it and air pollution affect astronomy.

    Light pollution is caused by bright light from nearby sources____ scattered by the air and makes the night sky seem to glow. Air_ pollution is dust or chemicals in the high atmosphere. Both of_ these make it hard to see dim objects. _____________________

  • Telescopes

  • Telescopes

  • Fill in Part 3a

    Explain why binoculars and telescopes are important astronomical tools.

    They make objects in the sky appear larger (magnification) and brighter (they collect more light) _

  • Fill in Part 3b Describe the similarities and differences of several types of astronomical telescopes, including at least one that observes light beyond the visible part of the spectrum (i.e., radio, X-ray, ultraviolet, or infrared). Some have a low resolution wide field of view, others have a high resolution but a narrow field of view. Some use lenses, while other use mirrors. Optical telescopes extend our sense of sight while radio telescopes look a things our senses cant_ detect____________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________

  • Fill in Part 3c

    Explain the purposes of at least three instruments used with astronomical telescopes. 1) Lenses: collect and focus the light ____________________ 2) Mirror: collect and focus light _______________________ 3) Camera : record what you see through the telescope_____

  • Care of Binoculars and Telescopes

    Handel carefully, do not drop or bump.

    Keep them clean, dirt, fingerprints, and dust will make the images blurry.

    Keep them dry to avoid fogging due to condensation

    Store in a cool dry place.

  • Fill in Part 3d

    Describe the proper care and storage of telescopes and binoculars both at home and in the field. Handle carefully, keep clean, keep dry, store in a cool dry____ location.___________________________________________ ____________________________________________________________________________________________________ ____________________________________________________________________________________________________ ____________________________________________________________________________________________________ ____________________________________________________________________________________________________
