Summary #4: Cycles of life

Examples of cycle important in the planet:

• Water cycle: the continuous movement  of water between Earth's  surface and the air, changing from liquid to as to liquid. Here in the water cycle alsso we find the freezing and melting point You can start in any place in tis case I gonna start in  evaporation-can be salty and fresh water: salty= beach, ocean etc. they evaporate more fast. 1. evaporation: liquid to gas, heat is absorb. 2.condesation: gas to liquid 3. precipitation can be. snow, rain, hail,sleet  3. freezing: liquid to solid  the heat is released. 4. melting: solid to liquid the heat is absorb.Also happen the runoff and transpiration that when the plants released the water that they have (they evaporate)
• Carbon cycle: the continuous transfer of carbon between the atmosphere and living things. Here you see the oxygen and carbon dioxide in the case of the plants they take the CO2 and produce O2. A car exhaust produce CO2 that is sometime very bad in our enviroment, death decay storage  produce CO2 animal and photosynthisis produce oxygen.
• Nitrogen cycle: the transfer of nitrogen from the atmosphere to plants and back to the atmosphere and directly into plants again, they start with the descomposition of animals or plants then came the ammonia, the bacteria, nitrites go to the plants, the plants absorb the nitrites also some animals then the denitrifying bacteria the go to the atmosphere (the air) and start again.

Summary #3: Food chains and food webs

The food chain is the path of energy in food from one organism to another. And the food webs are overpalling food chains in a community. In this are the carnivore ( meat eater ) herbivore ( plant eater ) omnivore ( meat and plant eater ). In this ccle are the predetors and the pray in the case of the meat eater.


1.In the food chain, they always start with the Sun then it passes the energy to the producer can be ( grass, trees, and those things, plants ) then came the consumer an  insect as an example, then came another consumer example and frog, another consumer example a snake, then came another consumer example an eagle the this animal descomposed.


2.In the food webs is differen because, as an example the rabbit eat grass but the mice also can eat also insect, the the frog eat grasshopper but it can eat other insect, so this means that dont only one have an especific food some can eat the same but they are differebt animals that eat it.


Some animals have the ability to be camuflage to dont be a easy prey like the iguana when it is smal they camuflage with the leaves and when they became bigger they camuflage with the trees so imagine in the forest you must dont see any animal but remeber hey are camuflage.
In my conclusion I think that this is important to us because people also is include in this so we need to know so we need to know a little of all. REMEMBER GO GREEN!

Summary #2: Living things and their Evironment

The ecosystem that is all the living things and nonliving things in an area interacting whit each other, is divided in two: biotic factor and abiotic factor.

1. In the biotic factor we have all the living things example. animals ( dog, birds, lions etc. ), plants are divided in vascular and non vascular ( trees, flowers, grass etc. ), bacteria ( bioluminescent bacteria ) , fungi ( the mushrooms ), protist ( green algea, diatmos ).
2. And abiotic are the nonliving things exaple: temperature, air, minerals, rocks, water, light, weather.

If we dont take care of the animals and they enviroment we can die because for example if the frogs extiguish the insects such as the mosquitos and others can produce disease and all these happen because the fro extinguish imagin that this happen ? and DISASTER true or false? TRUE, and only ONE imagine.

In my conclusion I think that the only recommedation that I give to you is to take care of our planet and what is in it is not only people also animals, plants and all the living things ad also non living things. Remember GO GREEN !

IV Quarter: Science Summery, Energy Resource

Do you know how energy is composed ? It is composed by food+Oxygen= Energy, all this together is= transpiration. A type of energy is (an example) fossil fuels but the fossil fuels pollute so for this exist de Alternative sources of energy. This type of energy do not pollute: some examples of tis are the

• Modern waterwheels: water energy. A hidroelectric plant uses moving water to produce electricity.
• Harnessing the wind: wind energy.
• In Earth's surface: geothermal energy.
• Solar energy: solar panels.

The edum corns produce gas methane.
For example here in Panama we present the water energy in the hidrolectric for example AES, La estrella etc.
How we can conserve Energy?
1. Using the alternativesources of energy. However the plant matter and animals wastes or other remains-called biomass can be used as a renewable energu source, plant and animal  waste that might wind ups aas garbage can be processed to form fuel. Woa! In me conclusion i think that we must used this alternative sources of energy, also we dont need to use the fossil fuels because this pollute a lot so WE NEED TAKE of OUR planet. GO green!!!
