ALWAYS:
- know that when you see the word 'read' you can access the audio version on Audible on the iPod nano
- have your book open as you listen to the module on Audible so that you can see the illustrations etc. and so you know when/where to stop
- Read each section and do the OYO as you get to them. Do not continue reading (listening) until you have completed the OYO questions and checked your answers against those at the end of the module.
- Spend 5-15 minutes on Quizlet to work on the vocabulary words for each section and the previous section's words as you complete each reading assignment.
- complete the study guide for each module
- if you don't understand a concept/section/topic go to the bottom of this post and check the 'extra help' links. If something is very interesting to you, check the 'interesting links' section for that module at the bottom of this post.

Module#12 - Arthropods
►In this post, there are several videos that did not have an embed code, so I just posted the link.
Here's a review of a few terms if you are still not quite familiar with them.
A shark has an anterior dorsal fin and a posterior dorsal fin. This indicates which is in front of the other; they are both on its back.
Something can also be "anterior to" another body part, meaning it is in front of it, and "posterior to" another body part would mean it is in back of it.
Remember the order of the biological classification:
read 361-364
(1) p. 361-364, General Characteristics of Arthropods
There is not a video that goes over the 5 characteristics, but here is what I could find.

Here's a review of a few terms if you are still not quite familiar with them.
- Dorsal - referring to the back, or it might seem to be the top if the animal is not upright like a human, but it is its back. Like a dorsal fin on the back of a fish.
- Ventral - referring to the front, or belly-side of an organism.
- Anterior - in front of, or the end that contains an organism's head.
- Posterior - in back of, or the end that contains an organism's tail.

Remember the order of the biological classification:
Kingdom, Phylum, Class, Order, Family, Genus, Species.
In this module, you will study phylum Arthropoda as well as a few classes and orders within this phylum.read 361-364

(2) p. 365-371, Class Crustacea: The Crayfish
Growing up, I always called these things crawdads. =)
A crayfish swimming, trying to catch food.
►Learn the parts of a crayfish by studying the names of the parts on p. 365.
►Then with your book open to page 365, look in your book as the highlighted parts in this video are named. Then go back and watch the video again and see if you can name the highlighted part before the words appear on the screen. The cephalothorax is called the thorax in this video. Actually, the head and thorax together make a cephalothorax.
Around 2:10, the parts named are the ones labeled on p. 373 in the dissection. Look there for comparing to the video.

(5) p. 376-379, Class Arachnida (Spiders!)
Again, there are no videos that deal w/ the 5 characteristics of arachnids, one of which is that they have a cephalothorax instead of a separate head and thorax like insects. So spiders only have two body parts while insects have three. Insects and spiders both have an abdomen.

Great web site which
shows man’s attempt at copying God’s exoskeleton design.The robotic extended
walker is a six-legged, pneumatically powered exoskeleton.If your student is
interested in robotics, this page will thrill him or her.
UC Berkeley researchers
attempt at developing a robotic exoskeleton that can enhance human strength and
endurance is shown. This one is interesting in that it is a post 9/11
development designed to help firefighters climb stairs.
Have you ever wanted to
jump like a grasshopper? According to the manufacturer, this personal vehicle
designed for the 21st century will have “you trotting four-minute miles without
tiring and scrambling up a mountain like an ATV.”

An insect's exoskeleton
(integument) serves not only as a protective covering over the body, but also
as a surface for muscle attachment, a water-tight barrier against desiccation,
and a sensory interface with the environment.It is a multi-layered structure
with four functional regions: epicuticle, procuticle, epidermis, and basement
membrane.This site is college-level look at this amazing structure.
Chitin is a white, horny
substance found in the outer skeletons of crabs, and lobsters and in the
internal structures of other invertebrates.It is a polysaccharide consisting of
units N-Acetyl Glucosamine and its highly crystalline structure accounts for
its poor solubility.This page will introduce the student to this important
biological compound.
Page contains colorized,
computer-enhanced, electron microscopic views of insects.The compound nature of
the insect eye can be plainly seen on these colorized plates.
This wonderful little

information on the care and feeding of the little buggers.

Super page! Well worth
the look with multiple links to spider information and facts.
Spider silk is an
extremely strong material and is on weight basis stronger than steel. It has
been suggested that a pencil thick strand of silk could stop a Boeing 747 in
flight.This awesome site explains the process of silk spinning.

wonders of spider silk.
How do spiders build a
web? It is an engineering marvel.If you can look at this page and still believe
that spiders just evolved and learned to spin webs by random chance, I have a
bridge and some swamp land to sell you.
Do spiders ever catch
anything besides bugs? There is one spider that is large enough to catch small
birds.This page has multiple links at the bottom regarding some very unusual
spiders.
Millipedes have 4 legs
per segment.Millipedes are docile herbivores and decomposers.Millipedes have
rounder bodies than centipedes.Millipedes are not poisonous.
Insects are an interesting
group.This fantastic web page from Animal Diversity Web provides 54 pages of
pictures and background information that your student should find
fascinating.Contains evolutionary content.
Insects have an
elaborate system of interconnecting tubes called tracheas. These tubes are
connected to the outside through a series of small holes in the exoskeleton
called spiracles. The network of tracheae is so complex and thorough that air
runs throughout the body, providing oxygen to all tissues! Air goes directly to
the tissues, where oxygen and carbon dioxide are directly exchanged with the
cells.
Hemolymph (or
haemolymph) is the blood analogue used by all arthropods and most mollusks that
have an open circulatory system.This page provides the components of this
interesting fluid.
Circulation, metabolism,
respiration, and excretion – every system that makes an insect a living thing
is discussed.Wonderful resource for this Module.
