1. Pg. 68 – Make a grid for the 6 vocabulary on pg. 69 & draw a simple drawing for each (like a logo) Nocturnal (Example) Diurnal CrepuscularHibernation MigrationEstivation

2. EQ: How do ectotherms & endotherms maintain homeostasis (a stable internal temperature)? Pg. 71 Cornell notes Not all information needs to be copied. Copy only definitions & information that you judge to be important.

3. Homeostasis The bodily process of maintaining a stable (constant) internal environment Examples: Humans keep a body pH of 7.4 (a little less acidic than water)

4. Homeostasis The bodily process of maintaining a stable (constant) internal environment Examples: Humans keep a count of about 70 trillion cells in their body.

5. Homeostasis The bodily process of maintaining a stable (constant) internal environment Examples: Humans keep an average internal temperature of about 98.6 degrees Fahrenheit.

6. Ectotherms “Cold-blooded” animals; have a wide range of body temperatures; rely on external sources of heat

7. Endotherms “Warm-blooded” animals; have a narrow range of body temperatures; maintain their body temperature from the inside

8. Watch the video about these ectotherms & endotherms Video on next slide EctothermsEndotherms Black-throated monitorRhinoceros River otterTurtles White-tailed deerAmerican alligator BirdsAtala butterfly

9. How do the otters stay warm? How do the turtles warm up? How does the deer cool down? How does the alligator cool down?

10. Otters = covered in thick fur to hold the heat they make Turtles = basking/laying in the sun with limbs stretched out Deer = moving warm blood through its large ears Alligator = laying in the shade while blood runs through its scutes; laying in the shade and opening its mouth

11. Ectotherms VS Endotherms Ectotherms use the outside temperature to warm up or cool down. Endotherms keep their bodies warm from the inside.

12. If the outside temperature is 10, 20, 30, or 40 degrees Celsius, the bobcat’s body temperature is still the same. The snake’s body temperature depends on the outside temperature.

13. Pg. 70 – Make a T-chart for ectotherms & endotherms. Then, look up these animals that the Phoenix Zoo needs better Animal Fact Sheets for. Sort the animals into the 2 groups. If you find an animal you are really interested in, you can call dibs on it by telling Ms. Beaith.
