Big Idea 1, Chordates

These fish in my fish tank are examples of chordates which are animals that have notochord, a hollow dorsal nerve cord, a post anal tail and pharyngeal slits. 



Big Idea 1,Bryophyte
A bryophyte is a non-vascular organism such as this moss that I found growing on some stones. These organisms are specified as such because they lack a true vascular system and don't have complex tissue organization.
Big Idea 1, Angiosperm
This plant is an example of an angiosperm which is a flowering pant that forms seeds inside an ovary in order to protect it. 



Bid Idea 1, Tetrapod
This rather large animal is my dog Dino and he is an example of a tetrapod. A tetrapod is a vertebrate that has two pairs of limbs. He more specifically is a mammalian example of a tetrapod. 

Big Idea 1, Modified Stem of a Plant
This small bamboo plant is an example of a modified stem because if the plant had been allowed to grow normally then the stem would have grown basically straight up however since it was modified it grew in a spiral pattern. 

Big Idea 2,  Xylem
This Coastal Redwood is an example of a xylem because inside of the plant the xylem is used to transport water up the tree to all the branches and leaves or in this case needles. 

Bid Idea 1, Arachnid
This spider web that I found between the stones on this wall is evidence of an arachnid which is an organism with 8 legs who's body is comprised of 2 sections. Spiders and scorpions are just a few examples of arachnids. 

Bid Idea 2 Adhesion of Water
Adhesion of water means that water will adhere to other objects or substances meaning that it will stick to it. this is important to know because water is so common in nature and is so important to life.

Big Idea 2, Unsaturated Fat
 This bottle of olive oil is an example of unsaturated fat. Unsaturated fats are fats that are liquid at room temperature and don't have a completely hydrogen tail rather they have a double bond that puts a bend in the stand which makes it so that the molecules can't pack close enough together to be solid.
Big Idea 2, Saturated Fat
This stick of butter is an example of saturated fat. Saturated fat is a type of liquid where at room temperature is solid because of its totally hydrogen filled tail. 
Big Idea 1 Amniotic Egg
This is an example of an amniotic egg; amniotic eggs are birds reptiles and egg laying mammals such as a platypus. These eggs are characteristic for their hard outer shell made of calcium or a leathery substance.
Big Idea 2 Stomata
This leaf is an example of a stomata because on the leaf's surface are openings called stomatas and these openings control the output of gases and water vapor.

Big Idea 2, Autotroph
This picture of a large plant is an example of a autotroph. An autotroph is an organism that is capable of producing its own food. This plant uses carbon dioxide and and sunlight as well as nutirents and water gathered from soil to create food for itself and in turn energy. 
Big Idea 3, Seed Dispersal Method
These seed pods hanging from the branches of a tree are examples of a seed dispersal method. These seeds are shaped in such a way to allow for them to be able to travel in the air if aided by the wind or to be allowed to slowly fall to the ground.

Big Idea 1 Fungi
This mushroom is an example of a fungi. A fungi is a is a type of organism similar to most plants however they lack cellulose in their cell walls and rather contain chitin in them instead. 

Big Idea 1, Lichen
This green looking plant thing that is on piece of wood i found is an example of a lichen which is a type of fungus that attaches to some sort of photosynthetic organism and feeds off of the energy that the host creates.
Big Idea 2, Transpiration
This green leafy bush is an example of transpiration. Transpiration is similar to evaporation and is the process in which water leaves plants mainly through their leaves in the form of water vapor and as it leaves the plant pulls more water up through cohesion. 

Big Idea 1, Adaptation of a Plant
This trimmed rose bush is an example of an adaptation of a plant because this plant has formed thorns which help it to survive by limiting the amount of animals that will try to eat it because of the possibility of injury. Thorns probably came about in this species through a mutation of some sort and then natural selection took over and helped the plant evolve into what we see today as a rose bush.
