Notes #3 Zoo Scavenger Hunt #1
Black Bear • Up to 600 lbs • Up to 6 ft long
Polar Bear • Up to 1400 lbs • Up to 10 ft
What is the unifying idea? • Ice cube • Many small vs one large • Which melts faster? Why? • Warm up • Small cube highest surface area / volume • Largest cube (4 in) had smallest ratio
Surface area to volume ratio in biology • Plants • Homeostasis of water • Gather sunlight • Animals • Homeostasis of temperature (thermoregulation) • Hummingbird: 3-4 years, 1260 bpm • Elephant: 50-60 years, • Mouse: 5 months / 2 yrs, 600 bpm
Cells • Surface area to volume ratio limits cell size • Plasma membrane (pm) decides what can enter / leave cell • Less PM = less ability to exchange with environment. • Organs • Greater surface area = better ability to exchange nutrients / wastes
