Scavenger History

Throughout the history of time, different cultures have held the title of master navigators. During the Han Dynasty, the Chinese invented the first compass, a device made out of lodestone – a naturally magnetized metal – and a bronze plate. Then, Arab mariners perfected astrological sea-faring, using the stars to guide themselves across the world’s waterways. But the ancient world’s true masters of navigation were early Polynesians. While today’s modern ships are covered in gadgets, this civilization perfect a life on the water. Without maps, compasses, sextants or clocks, for thousands of years they read the skies, waves, birds and wind to find their way between specks of land in the vast Pacific. These observation-based traveling techniques…show more content…
They’ll be putting their navigational skills to the test, competing against other tribes as they design scavenger hunts.

Day 8 of Survivor Camp combines pacing, navigation and a compass in a Scavenger Hunt Challenge.
Prep Scavenger Hunt and DIY Compass handouts in page pockets.
Find a wide open area for the scavenger hunt.
Secure 5 navigation cards in the middle of the area as starting points for each tribe’s scavenger hunt.
Fill the plastic bin with water for DIY compasses. The water only needs to be about four to six inches deep.
Tribes need leaves to create DIY compasses. Broad green leaves work best. A section of cork also works well if it’s not a good season for

Make a number sentence using all five cards and any operations to reach the target number. Write and solve the equation at the bottom of the page pocket.

For example, suppose the target number is 20 and the cards in play are 5, 4, 6, 2, and Ace (in the case making the Ace worth 1). One winning combination is: (5 x 2) + (4 + 6) / 1 = 20.

If a team is struggling to find a combination to hit the target number they can draw an additional card from any deck and try to make a combination using six cards. This is a natural time to review Order of Operations.

A common technique for remembering the order of operations is the acronym "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". Fraction Fun: Choose one more number between 1-10 and pull five cards from the deck. Create fractions out of the first four cards that equal a fraction formed out of the last two cards. Decide which cards to use as numerators and which cards to use as denominators. Add, subtract, multiply or divide the fractions to create a true number
