The document discusses the LSU Museum of Natural Science and its collections related to Louisiana rocks and minerals. It describes the museum's mission of acquiring, preserving, and studying collections to generate knowledge about biodiversity, geology, and human history. It provides details on the paleontology, vertebrate paleontology, mineralogy, petrology, and Louisiana Geological Survey collections. It also describes educational field trips and hands-on activities for learning about minerals, rocks, and geology.

Introduction of Fish and Fisheries of India.
• Freshwater Fish: Fish that spend most or all of their life in freshwaters, such as rivers and lakes, having a salinity of less than 0.5 ppt. Around 40% of all known species of
fish are found in freshwater.
They may be divided into Coldwater Fish (5-20 °C); examples: Mahseer, Trout, etc., and Warmwater Fish (25 35 °C); example: Carps, Catfish, Snakeheads, Featherbacks, etc.
• Brackishwater Fish: Fish that can tolerate a wide range of salinity (0.5 30.0 ppt)
and live in backwaters, estuaries and coastal waters.
Example: Mullet, Milkfish, Seabass, Pearlspot, Mudskipper, etc.
• Marine Fish: Fish that spend most or all of their life in seawater, such as Seas and
Oceans, having salinity above 30 ppt. There are about 240 species contributing to
the marine fisheries. Example: Sardines, Mackerel, Ribbonfish, Anchovies, Grouper, Cobia, Tuna, etc.
Fish are all members of the phylum Chordata, sub-phylum Vertebrata. Fish are generally spindle-shaped, oval in section, and flattened either sideways or dorsal-ventrally. The skin is covered in protective scales, with some exceptions (lampreys, ocean sunfish). All fins have fins of some sort, all the size, number, and shape vary. Fish breathe through gills, and only a very few have actual lungs. Most fish have a special organ known as a swim bladder that prevents them from sinking, and, in some cases, aids in respiration. The common name "fish" refers to four different classes, depending on the person classifying them (there are numerous different ways to classify fish). Bony fish also have special adaptations that allow them to remain buoyant. A special organ called a swim bladder housed under the bony skeleton is a gas filled chamber that allows the bony fish to remain floating in the water. Some fish have a connection between this organ and the digestive tract to allow the extraction of oxygen. Another special adaptation is the operculum, a flap on each side of the fish that covers the chambers housing the gills. A bony fish is able to breathe without swimming simply by moving the operculum. Other hallmarks of these fish are paired fins, many teeth, dermal scales in the skin (in most species), and numerous vertebrae. Most bony fish are ray-finned fish, meaning that they have thin, flexible skeletal rays. Lobe-finned fish, the other type of bony fish, have muscular fins supported by bones. Only one species of lobe-finned fish, the coelacanth, still lives. However, it was the lobe-finned fish that made possible the colonization of land.
Brackish water is a mixture of fresh and salty water which usually occurs in estuaries, and has a salinity usually of between 15 and 30 per thousand, depending on rainfall and freshwater run-off. Some fish species like mullets are able to survive in this environment.

Earth science is a broad spectrum of science that covers life science and physical science. Life science is all about the study of living organisms and their relationships including biology, anatomy, ecology, etc.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
This slide is special for master students (MIBS & MIFB) in UUM. Also useful for readers who are interested in the topic of contemporary Islamic banking.

Palynomorphs =
- both plant and animal structures
- microscopic in size (from about 5 µm to about 500 µm)
- made of compounds that are highly resistant to decay
- abundant in most sediments and sedimentary rocks
- can be extracted by chemical processing (acids digestion & sieving)

14. What is Geology?
Study of the origin, history, and stucture of the Earth
as recorded in the rock record.
The Earth is composed of different types of rocks and
minerals.
Geology: The Basics
Geologists are the scientists
who study these rocks and
minerals.
15. • Naturally occurring
-man-made substances would not be considered a
mineral
• Inorganic solid
- Inorganic substances are those that are not living or
formed by living processes
• Specific chemical composition
• Unique crystal structure and properties
-Atoms are arranged in a orderly, repeated pattern
-Physical properties include color, luster, streak,
cleavage, etc.
MINERALS
16. Rocks- An aggregate solid of one of more minerals
in different proportions.
Chocolate chip cookie analogyChocolate chip cookie analogy
Cookie = rock
Ingredients = minerals
Oven= Earth’s heat
Rocks
Rocks are divided into three different types based
on how they are formed:
Igneous, Metamorphic, and SedimentaryIgneous, Metamorphic, and Sedimentary
17. Igneous
The word, igneous means from fire or heat.
Igneous rocks form when molten lava (magma)
cools and turns to solid rock. There are two
types-
Intrusive- cools slowly inside the Earth (Examples=
Granite). They have large mineral grains
Extrusive- Magma that reaches the earth’s surface and
cools relatively quickly. (Examples- Basalt, obsidian,
pumice). The mineral grains are small.
Note: MAGMA- inside the Earth, LAVA- outside
of the Earth
18. Metamorphic
These are rocks that have changed (Examples- marble, schist)
From the Greek words “meta” and “morph” which means to
change form. They were originally sedimentary or igneous
rocks that changed due to heat and pressure often from eh
movement of the Earth’s crust.
Sedimentary
Rocks composed of grains of clay, mud, sand, and dirt.
(Examples- sandstone, limestone)
These form when sediments are weathered and deposited
as layers into streams, oceans, rivers, and lake. After thousands
and millions of years the weight and pressure of all these
sediments eventually turn them into sedimentary rocks!

GEOLOGIC MAPS
Definition: Map designed
to show the distribution
of geologic features such
as different rock types
and faults in the area.
• Only show geologic units that are exposed on the surface
• Different colors symbolize a different geologic unit
* This activity can be used in conjuction with the Fossil gravel activity

Holocene AlluviumHolocene Alluvium (= youngest rocks)(= youngest rocks)
These are the abundant sand and clay riverine deposits deposited by the
Mississippi, Ouachita, Red, and other rivers within coastal
environments. These represent over 50% of surface exposed rocks.
Pleistocene terracesPleistocene terraces
These deposits consist of sand, gravel, and mud that are remnants of
preexisting riverine flood plains. They are found near modern rivers
and coastal plains. ~25% of surface exposed rocks.
Tertiary rocksTertiary rocks (= oldest rocks)(= oldest rocks)
These are associated with rver flood plains, coastal plains, and shallow
sea environments that occurred due to fluctuating sea levels. Oldest
rocks are Late Cretaceous marine rocks (70-82 million years old)
outcrop in Bienville parish. These are highly fossiliferous marls and
chalks.
Editor's Notes
We know that, because when studying these in situ rocks, we find fossils that tell us how this environment looked like.
But how are these creatures still found today? They are fossilized…
