I am hoping you will find my teaching resources of value to use in your classrooms. I taught for 33 1/2 years. I was awarded both the NY State Elementary Social Studies Teacher and the National Council for Social Studies Elementary Social Studies Teacher of the Year(1988).

JUNE IS BRAIN AWARENESS MONTH
COOL BRAIN FACTOIDS!
Gail SKroback Hennessey
The brain is made up of five main parts: the brain stem, pituitary gland, hypothalamus, cerebellum, and the cerebrum. Learn some cool facts about your brain! Share these facts with students.
• Did you know that the brain is about 3 pounds in weight?
• The largest part of the brain, or 85%, is called the cerebrum.
• Did you know that 75% of the brain is made up of water?
• The brain feels no pain as there aren’t any pain receptors in the brain.
• If you lined up all the neurons in your brain, they’d stretch about 600 miles! That’s because there are about one hundred BILLION neurons in the brain. They are very tiny. About 50 neurons could be lined up side by side across a dot. What’s a neuron? It’s a nerve cell.
• You can’t tickle yourself! That’s because the brain can tell the difference between your own touch and an external one.
• Did you know that there is a BRAIN BANK at Harvard? It’s the largest such “bank” in the world. About 7,000 brains are stored at the bank for research.
• Mummies of ancient Egyptians have been found with drilled holes suggesting people had some sorts of brain surgery in ancient times.
• You could use a butter knife to cut the brain. It is THAT soft.
• Your brain creates about 25 watts of energy while you are awake, enough to light up a light bulb.
• Ancient Egyptians didn’t see any value in the human brain. It was removed via the nostrils and thrown away in the mummy-making process.
• Wow…it is estimated that we have 70,000 thoughts each and every day! That’s a lot of thoughts…hopefully they are positive ones.
• 170 mph is the speed in which nerve impulses travel to the brain and back.
• Scientists say we blink about 20,000 times each day. The brain keeps the world from going dark each time we blink.
• The hypothalamus is your brain’s thermostat. It monitors your body temperature. If it is too high, you sweat to help cool down. If your body temperature gets cold, you shiver to warm up.
• Have you had a “brain freeze”? The correct term is sphenopalatine Ganglioneuralgia.
• Often nicknamed, the “grey matter”, the brain is actually a pink-beige color.
• It is estimated that the brain has about 100,000 miles of blood vessels!
• Eating eagle hearts and crushed lizards was thought, in the middle Ages, to be brain food!
• Our brain’s very short term memory(working memory) can remember up to about seven digits at a time before it is forgotten. Hmmm, no wonder telephone numbers are no longer than seven digits!
No matter your political leanings, with the upcoming Presidential election, Hillary Clinton has made history becoming the first woman ever to lead the presidential ticket of a major political party(the Democratic Party). As a history teacher, I am so very excited to see this historic event unfolding in my lifetime. Many, many women(and men...) worked hard and suffered much to create an environment where this has finally become possible. Gail Check out this Reader's Script on Hillary Clinton where kids learn about Hillary's childhood and career to the present. TRIVIA: Hillary wanted to be an astronaut and at the age of 14 wrote a letter to NASA. She was very disappointed to learn that girls could NOT be admitted to the astronaut program(that would change in 1978).Grades 4 and up. Comprehension questions,discussion questions and activities as well as links for more information are also included:
