Road Less Traveled Doing what is right is not always popular-(the 4wheel drive road). Doing what is popular may not always be right-(big highway).

IN-A country western song has a phrase “all that glitters is not gold”. How can you use that thought in your daily life? OUT- The first thing scientists look at when they classify mollusks is whether or not the animal _____________________.
3
Mollusks the body plans of mollusks include a mantle, visceral mass, head, and foot. Classification of Mollusks – Gastropods typically have one shell, a foot, and eat using a radula (a file-like tongue). – Bivalves have a hinged two-part shell, a muscular foot, and eat by filtering their food from the water. – Cephalopods have a head, a foot which has been modified into tentacles, and a well-developed nervous system. Value of Mollusks – Mollusks are food for many animals, have commercial uses, and are used for research.

Reading pages 360-364 and taking Cornell notes
5
IN - Mussles, Clams, Oysters and scallops are often called “shellfish”, why is this misleading? OUT - Why is an open- circulatory system able to meet the needs of a gastropod & not an octopus

I’m off to Red class, I hate mornings. GASTROPODS- “stomach footed” ~75,000 species~ Why am I most active at night or on cloudy days ?
8
BIVALVES-why did they name that? Pssst, what does it mean to clam up? ~30,000 species~
9
Do I look like I have a “HEAD FOOT”? Cephalopods
10
Hi, I’m a squid-I have a well developed nervous system and large eyes We are all predators
11
I have an internal shell (cuttlebone), I am also well known for my ability to rapidly change colors, color patterns, color Intensity to blend in with my background. Who am I?
12
Have you looked in the mirror lately ? I have a closed circulatory system- unlike other mollusks, because I love being active!
13
IN -Identify some positive and negative ways that mollusks affect humans. OUT - Why is it unlikely that you would find garden slugs or land snails in a desert?
14
IN- How can I use the idea of an “oyster turning a grain of sand into a pearl”, when I work with others? OUT- “When you are not working out, someone, somewhere is and when you meet, they will win!” How does this quote relate to our video “the survival game”? 10/25
15
In- Tangled up w/reefs OUT- What physical feature is unique to ECHINODERMS?
16
OUT- Why must animal species adapt to their environment ? IN-Why would the ability to regenerate lost body parts(arms) be an important adaptation for sea stars, brittle stars, and other echinoderms?
17
Echinoderms have a hard endoskeleton covered by bumpy or spiny epidermis; They have radial symmetry, a mouth, stomach, and intestines. They have no head or brain, but they do have a nerve ring around the mouth. They have a water-vascular system connected to thousands of tube feet. Examples~sea stars, brittle stars, sea urchins, sand dollars, sea cucumbers
