summary #8

In this topic I learn about the blood system.
I learn that the plasma is a plate- yellow liquid part of the blood that contain nutrients , also that the hemoglobin is a chemical that carries oxigen around in the body ,also about platelets that is a cell  fragment in blood that helps blood to form clots, arteries are blood vessels that carries blood aaway from the heart ,the veins also are blood vesselsthat carries blood toward the heart, capillarythe smallest type of blood vessels ,where materials are exchanged between blood and body cells transfussion is when is taking blood from one person to another person , antibody is a protein in blood that help destroy materials that can be harmful.

summary # 7

In this topic I learn how Ecosystem change.
The Ecological succession is the gradual replacement  of one community by another, the first animal that get into a new place is the pioneer specie,when there are the first  comunity in a place it is called pioneer .community, and the climax community its form by the final stage of succession in an area.







summary #6

In this topic I learn more things about the climate and animals and where they live.
They live in diferents biomes that in the biomes have his own climate , vegetation , animals.
Panama is in the tropical rain forest that in this biome have more animals , plants and vegetation that  each other.
Taiga is very cool they have less vegetation , animals , water.
Desert they have not too much animals ,  plants and rain . the Desert is the most arid biome that exist.
Tundra is cold , tree less and farnorth , marked by spongysoil.

summary #5

In this topic I learn that in the ecosystem many animals survive by others .
In the parasitism an example can be a dog  and a flea that the flea is benefit and the dog is harm.
A example of commensalism can be a orchid and a tree in this realation ship the orchid is benefit but the three isn´t harm.
In mutualism an example can be the yucca moth and the yucca tree that in the relation ship the two are benefit.

Cycles of Live

In this topic I learn many things like the decomposers help in the nitrogen cycle.
First I will explain what is a cycle a cycle is a process that have no begining and no end.
In the water cycle  they are things that help in this cycle like the sun, the trees. The sun help evaporating the water , the trees help by transpirating.
In the carbon cycle also the trees help by changing the carbon dioxide into oxigen.

summary #3

food chain and food webfood chain: the path of enegy in food from one  organism to another they always start with sun and finished with discoumpousers
food web: the overlapping food chainsin a community they always start with producers and ends with living things.



summary #2

living things and their envirment
The living thing or biotic and nonlivving things are found evrywhere . living things need non living things to survive.   the science that studies how living things an their envirorment interact isan e called ecology. Every living thing has a role or a niche,  an example of this is that every organism reproduce.
Examples of biotics factors:
animals
plants
fungie
algae
bacteria 

Example of abiotic factors.
mineral
rock
water
wind


summary #1


Enegy reasources are reasouces that can be use as energy example of energy that contaminate fossil fuel that do not contaminate wind solar energy water energy the energy can be use in many ways like seeing television using the cars evry thing now use enrgy. Brazil is the number one country dont contaminating they do not use fossil fuel they use somting that when the corn fermentaid something that can be use as energy for making that they need corn a special box without howls and bacterias.

album#2

The planets are large bodies that are in  a solar system.


Mercury : is the first planet from the sun it is a big rock that is hot.

Venus : is the second planet from the sun is bigger than mercury but also is hot.

Earth : is the third planet have a perfect distance from the sun , is the only planet now that can have live in it.

Mars :is the fourth planet and also Mars is calledthe red planet beacause it shines and planet see red.

Jupiter : is the fifth planet is one of the biggest planets a year in Jupiter have 4,333 days.

Saturn  : is the sixth planet from the sun and to complete a spinning takes 10 hours and 40 minutes and a year takes 10 ,759.

Uranus : is the seven planet from the sun and a year there takes 30,685 days and a day takes17 hours and 14 minutes.

Neptune : is the last planet  and so hit has the biggest orbit and a year takes 60,188 days.

Pluto :  is not a planet bea cause he have not the size needit to classify it as a planet and it have not a normal orbit beacause it pass through the orbit of  Neptune it is classify as a big rock.

conclusion : they are not galaxy without planets and that the Earth is the only   planet  that can have live now so take care of it  and if you don´t take care of it the Global Warming will come in less time.

Invisible Light Album

Introduction:

Most of the light move in straight line but the invisible light move in waveslenghts,also the invisible light is part of the Electromagnetic Spectrum.People can not see waveslenghts longer than red and shorter than violet,we can detect them, and we can use it in many ways this light is called invisible light.

Examples of Invisible Light:

Radio waves: the Radiowaves have the longer wavelenghts of the Electromagnetic Spectrum (1,000 meters) so they use it to carry signals in codes (AM,FM).Radio stations use Radio waves to carry sounds.

Microwaves: Is a short wave radio waves.Water in food absorb micro waves very readily.The energy from the absorbed  microwaves speeds up the the water molecules inside the food.

Infrared light: It means "just beyond red."Infrared waves are next to visible red waves in the spectrum .When you stand in sun light , it is Sun`s infrared waves that warm you.

Ultraviolet light :  Ultraviolet light is made up of waves just shorter than visible violet light on the spectrum.
(UVlight) is also a form of call the ultraviolet light. UVlight give us vitamin D that help us for have healthy bones.

X rays and gamma rays: the shortest waveslengths of the spectrum are the X rays and Gamma rays. They are dangerous for health. X rays can pass right through most objects. Thicker or denser object tend to absorb X rays. This means that x rays can produce a picture when they pass through an arm or leg, or your jaw. The denser objects such as bones and teeth, can show up very clearly on the finish pictures.


Blu ray: Blu-ray is an optical disc format such as CD and DVD. It was developed for recording and playing back high-definition (HD) video and for storing large amounts of data.

Conclution: There are many wavelenghts that we cant see, but we can detect them. We call this Invisible light and they have importants properties and uses.
