• RED SLIDE: These are notes that are very important and should be recorded in your science journal.

-Nice neat notes that are legible and use indentations when appropriate.

-Example of indent.

-Skip a line between topics -Don’t skip pages

-Make visuals clear and well drawn. Please label. Kidneys

Urinary Bladder

• RED SLIDE: These are notes that are very important and should be recorded in your science journal.

• BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

• Keep an eye out for “The-Owl” and raise your hand as soon as you see him.– He will be hiding somewhere in the slideshow

“Hoot, Hoot”“Good Luck!”

The Endocrine System

• Activity! The visual response and your endocrine system.– I will show 5 relaxing slides

• Let’s begin by taking some notes.

Take 1 minute to return to a normal state.

• The loud whistle and visuals that just scared you even more is a great example of the nervous system and the endocrine system.

• The loud whistle and visuals that just scared you even more is a great example of the nervous system and the endocrine system.– The nervous system relayed the loud noise to

your brain through neurons.

• The loud whistle and visuals that just scared you even more is a great example of the nervous system and the endocrine system.– The nervous system relayed the loud noise to

your brain through neurons.– Your endocrine system just flooded your

bloodstream with chemicals to put you on high alert.

• These chemicals told your body to speed up your heart rate, which has an influence on your breathing.

• These chemicals told your body to speed up your heart rate, which has an influence on your breathing.– This built-in flee response is great for survival.

• Let’s relax for a few seconds and let our bodies readjust to a calm place of learning.– I promise there will not be another whistle.

• The Endocrine System

• Question: What do these do?

• Now that you have been relaxed for awhile, your body is producing a different chemical to help return your body to a normal state.

The endocrine system is a system of glands that release chemical messages into your body.

Learn more about the endocrine system at… http://kidshealth.org/parent/general/body_basics/endocrine.html

Gland: A cell, a group of cells, or an organ that produces a secretion for use elsewhere in the body.

• Hormones released into the circulatory system (bloodstream) travel to the whole body.

• Hormones released into the circulatory system (bloodstream) travel to the whole body.– Remember: The network is over 100,000 km

Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.

• Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.

• Name some of these activities!

• Some activities in the body…• Growth • Sexual development• Reproductive cycle • Digestion• Sleep• Hair growth• Hunger• Blood Production• Much More

“I hope he can digest all that

food.”

“I hope he can digest all that

food.”

• Let’s see if looking at some food stimulates our hunger and salivary glands for 5 slides.

Too bad we can’t smell fresh baked cookies right

• Hormones can speed up, slow down, turn-on, and turn-off activities in your body

• Some important hormones– Insulin – Testosterone – Estrogen – Adrenaline

• epinephrine

– Dopamine – Melatonin – Thyroxine

• epinephrine

• Video! Rollercoaster – http://www.youtube.com/watch?v=0WpNSImh6Z8– Can we arrange ourselves like a roller coaster,

lean back, forward, side to side with the coaster.• Did your adrenals kick in while watching this video?

• epinephrine

• Dopamine plays a major role in the brain system that is responsible for reward-driven learning. – A variety of highly addictive drugs, including

stimulants such as cocaine and methamphetamine, act directly on the dopamine system

• Dopamine plays a major role in the brain system that is responsible for reward-driven learning. – A variety of highly addictive drugs, including

stimulants such as cocaine and methamphetamine, act directly on the dopamine system

• In one study, laboratory animals pressed levers to release methamphetamine into their blood stream rather than eat, mate, or satisfy other natural drives.–The animals died of starvation while giving

themselves methamphetamine even though food was available.

• Video Link! Dopamine and Meth, lab rat studies.– http://www.youtube.com/watch?v=at3Sg6qvgTE

• Meth (Methamphetamine)– Stimulant drug (One of the most dangerous in

the world).– Drug smoked in glass pipe.– Can be injected, snorted, swallowed– Many withdrawal symptoms– “Meth Mouth” – Teeth Decay Rapidly– Death from cardiac arrest, stroke,

hyperthermia
