A song all about Lewis and Clark and the Louisiana Purchase
Extras I stole from someone else's blog!
Lewis and Clark The Great Journey West- available on Netflix
SCIENCE
The Incredible Human Machine- National Geographic- available on youtube and netflix- this is an amazing documentary. I highly recommend watching this one but note it is rated TV14...the first part has a naked woman, but it doesn't show anything, then after that it shows surgery and the like. At the end of 7/9 and beginning of 8/9 it does a very scientific explanation of sperm and ovary. Nothing is shown that is inappropriate, but Mom should preview just in case.

MATH
These are great, I found them on another blog, but can't figure out how to get to the other ones.
We've covered much of the below, but will be going over it again soon.

BALANCE-Day or Night, Ears Keep You Upright
Ears do more than hear. They keep you balanced, too. In the inner ear, there are three small loops above the cochlea called semicircular canals. Like the cochlea, they are also filled with liquid and have thousands of microscopic hairs.
When you move your head, the liquid in the semicircular canals moves, too. The liquid moves the tiny hairs, which send a nerve message to your brain about the position of your head. In less than a second, your brain sends messages to the right muscles so that you keep your balance.
Sometimes the liquid in your semicircular canals keeps moving after you've stopped moving. To understand this, fill a cup halfway with water. Now move the cup around in a circle in front of you and then stop. Notice how the water keeps swishing around, even after the cup is still? That's what happens in your semicircular canals when you spin in circles or go on the Tilt-A-Whirl at the amusement park.
When you stop spinning or step off the ride, the fluid in your semicircular canals is still moving. The hairs inside the canals are sensing movement even though you're standing still. That's why you might feel dizzy — your brain is getting two different messages and is confused about the position of your head. Once the fluid in the semicircular canals stops moving, your brain gets the right message and you regain your balance.
INTESTINAL TRIVIA
-Food passes through the small intestine in just two hours; zipping along at 0.002 mph. Inside the large intestine it takes about 14 hours, traveling at a more leisurely rate of 0.00007 mph.
-If you expel gas consistently for 6 years and 5 months and 4 days, enough gas is produced to create the
energy of an atomic bomb.
-The large intestines are five ft (.61 m) long and are three times wider than the small intestines. The small intestines average about 22 ft. long!
SKIN/HAIR TRIVIA
-The average human has as much hair as the hairy primates, but only it is short and fine.
-Each hair on the scalp has a life span of about three years. Eyelashes have a life span of about 150 days.
-The soft down-like hair of the newborn sometimes reappears on the body of the aged.
-Most people shed 40 lbs (16.14 kg) of skin in a lifetime.
-The dust in your house is primarily dead skin.
-The dust in your house is primarily dead skin.
LUNGS
-Humans breathe 20 times per minute, more than 10 million times per year and about 700 million times in a lifetime.
-You will die of carbon dioxide poisoning if you are locked in a completely sealed room rather than oxygen deprivation.
-The longest word is English language is pneumonoultramiscroscopicsilicovolcanoconiosis - an inflammatory lung disease caused by the inhalation of fine silica dust.
