Global warming Causes, Effects and Cures.

🌎Global Warming🌎

{Write about global warming - Cause, effect and cure}

The causes for global warming is pollution from cars, motorbikes, planes, etc. There are a factor of greenhouse effects too, as if the sunlight will bounce back to it's own spot, it is stuck in the atmosphere. About ninety percent has been the effect of greenhouse effects. This affects our world, every year the sun gets hotter and hotter every year, isn't it enough to make our world hot? Aren't you sweating? It's hotter and hotter, this doesn't effect only our lives, it effects the antarctic world, especially the polar bears. Therefore, we will have to make our world better by reducing pollution; not using cars, walk to school or use the sky train or subway. It is enough to make our world this hot. The highest temperature for Thailand is 42°c which is already hot. Furthermore, we also have to reduce waste, or else there will be more gases and carbon dioxide. We also have to recycle, reuse and reduce. Try to use things more efficiently! Keep up the cures for our world.

Summary of what we have learnt

🍁What have we learnt so far?🍁

What have we learnt is the topics of: Terrarium, Adaptations, My favourite activities, What is my symbiosis poster about, The Pyramid Food Chain, Decomposers, and Science Review Sheet.

We have done this in all of this term, as we approach next term, I will be able to write more than 10 posts (if possible). In addition, I had a lot of fun doing blogs and posts in our lesson in Panyarat High School. I would like to say that I enjoy all of my teacher's lessons. 

All of my favourite activities overall was making the Science Review Sheet for our Final exams because this is helping my friends review for the finale exams too! I hope this also helps my friends and the viewers for their knowledge and use for the lessons too.

The blog and the posts isn't so hard to make, therefore this will help me and help you to learn more about the things more about science. I could make blogs every week if available.

Science review (PHS)

🔱Science review🔱

Definitions:
Adaptations - are special characteristics that help an organism to survive successfully in it's habitat.
Decomposer - an organism that feeds on dead organisms and waste.
Producer - an organism which is part of the first level of the food chain which produces it's own food.
Consumer - an organism that feeds on other organisms in a food chain.
Image result for biomesTaiga - Swampy coniferous forest of high northern latitudes.
Tundra - Treeless arctic region of Europe, Asia and Northern America.
Marine - Found in or produced by the sea.
Chaparral - Vegetation consisting chiefly of tangled shrubs and thorny bushes.
Estuary - The mouth of a large river.
Biomass - The total mass of living material in an area.
Numbers pyramid - The length of each bar shows the number of organisms at each level in the food chain.
Symbiosis - an interaction between two organisms
Commemsalism - Relationships between two organisms where one organism benefits from the other (for example; shark and echneidae, clown fish and anemone.)
Parasitism - A non-mutual symbiotic relationship between species where one species, the parasite, benefits the host (for example; parasite and human, louse and human.)
Mutualism - Each organism gets individual benefits (for example; bees and flowers, crocodile and plover bird.
Niche - The function or position of a species within a community.
Competition - A fight of two organisms for thing s that need to survive.
Classification - Arrange shared qualities.

1) The scientific method
    Image result for scientific method
  • Design an experiment
  • Make a model
  • Gather and evaluate evidence
  • Collect data / record observations
OR
  • Ask a question
  • Make a hypothesis
  • Design an experiment
  • Observe the results
  • Make conclusions
  • Communicate

2) Difference between observation and inference
The difference between observation and inference is that an observation is when you look and record a thing, an inference is a logical reasoning.

3) What do plants compete for?
Image result for competitionPlants compete for sunlight and water to make food (photosynthesise) and to grow.

4) What do animals compete for?
Animals compete for food, water and mates.

5) What do humans compete for?
Humans compete for food, water, work and money.

6) Describe decomposers, consumers, producers and the first, second an third consumers.
All of these are part of the food chain, decomposers decompose dead organisms, first level consumers eats the producers (herbivores), the second level consumer eats the first level consumer. Finally, the third level eats the second level consumer.

7) What are the five kingdoms?
Image result for five kingdoms
  • Animals - Cheetah, leopards, cats, dogs, etc.
  • Fungi - Mold, yeast, etc.
  • Plants - White alder, grass, trees, dandelion, bushes, etc.
  • Bacteria - Vibrio, bacillus, etc.
  • Protoctista - Amoeba, algae.
8) Why is it important to preserve the environment instead of using it for profit?
If the environment is better, it will be better for our economics,
- Attract the tourists
- Make more rice even faster because rice in China is the 1st produced in the world.
- Make the country and the people inside the country even healthier.

9) Why is it important to prevent organisms from foreign places from coming into other countries?
Because not all animals are adapted to our environment, so do we, this may cause;
- Cause of extinction
- Makes more animals endangered
- Destroys our ecosystem.

Image result for GMO10) Why should people use genetically modified organisms (GMO)?
This strategy makes the plants stronger and may give us more products, and uses less of our water (clean water). There are many more reasons to support this idea.

Decomposers

Decomposers

An ecosystem is all of the living and non-living things in a habitat. Every organism in a food web is a producer, consumer or a decomposer.

As you all know, to decompose means to rot. A producer can be called a plant or a autotroph, and a consumer can be called an animal or heterotroph. All decomposers feed on dead organisms and waste.

Image result for food chainDecomposers recycle the nutrients into the ecosystem. Fungi and bacteria are decomposers. All food chains start with a decomposer then a producer then a 1st level consumer then a 2nd level consumer, and so on... 

Nutrients are recycled by decomposers. The food consumed will have to separate into 3 groups; 30% lost as heat, 10% used for growth, 60% lost in waste.

Pyramid food chains and food webs

🔱Our pyramid food chain🔱

We have a food chain with three animals as follows;
Our food chain has grass (producer / autotroph), bird (primary consumer / heterotroph), and humans (secondary consumer / heterotroph). As we are the top of the food chain, we eat the primary consumer. For example: we eat fish, sheep, beef, pork, etc.

We are the top of the food chain, we can be omnivores or carnivores. We have another name; heterotroph; means that we use organic carbon for growth. We are the 2nd consumer (in level). 

As food chains get bigger, they turn into food webs, which are even bigger. Furthermore, there are two types of pyramids in a food chain - pyramid of numbers and pyramid of biomass. 

In addition, there are 5 levels in a food chain starts off with a decomposer, followed by a producer, followed by the 1st to 3rd consumer. As for our food consumed, we have to lose heat 30%, use 10% for growth, use 60% to lose waste. 

There examples below for you to examine 🔎.

What is my symbiosis poster all about???

💧What is my symbiosis poster about?💧

Image result for protocooperation bee and flower           My poster is about how animals cooperate with each other (Protocooperation(+,+)) which they also have benefits for each other. In addition, there is also predation which is the action of attacking of one animals on others a secondary consumer eating a primary consumer (+,-). Finally is competition which is a fight of two organisms for things that need to survive or save the species such as food, mate or living place (-,-).
This poster is a project on protocooperation, predation, and competition. There are pictures that you can look at which are the examples of what my poster is all about. There are benefits and damages to the environment.
For example, the (+,+) which will be totally healthy and beneficial to the animals. The (+,-) sign will be only benefit the one of them and the other will have a disadvantage. The (-,-) will not beneficially benefit either of them.

Favorite Science Activities

 Favorite Science Activities

My favorite activity in science this term is doing the terrarium project by putting the fish into a bottle with some plant. This was on my last blogger. My other favorite activity is when we write about adaptations and predator and prey. I like being in the lab to do some activities with Teacher Gary I really enjoyed it this term.

My least favorite activity is trying to revise for the vocabulary test and the Mid-Term Exams, therefore I think it was really exhausting. But it was totally worth revising for a good mark. Other than that, I don't have any more 'least favorite activity' to describe anymore.

This term, I have a lot of favorite activities to describe but I have only few sentences to describe 'least favorite activity.'

Description by; Prawan M1/102 (PHS)

Prey and predator adaptations.



This is a cheetah attacking a gazelle at 110 kilometers per hour (110kmph). The gazelle has high speed to run rapidly away from the cheetah, the gazelle also has excellent vision to see the cheetah from afar. Whereas, the cheetah has excellent vision to see the gazelle but not that stealthy, furthermore, the cheetah has weapons for example; very sharp claws and teeth.

The gazelle's long limbs allow it to sprint rapidly out of range or predators. Their long limbs allow them to sprint rapidly out of range of predators. Their tan coloration help gazelles blend in with their environment, making them more difficult to spot by predators. Like many animals, gazelles use gestures and certain postures as warning communication in order to prevent conflict.


Common predator adaptations:
-Excellent vision
-High speed
-Weapons (sharp claws and teeth)
Common prey adaptations:
-Excellent vision
-High speed
-Defense (horns)
-Camouflage (tanned color skin)

The Terrarium Project

Friday 1st July 2016

The Terrarium Project

Equipment we need;

  • A 1.5 liter bottle
  • A fish and shrimp
  • Water (very necessary)
  • Freshwater plant (necessary if you you don't have a plant which the fish eats).
What we are going to do;
  • Get a 1.5 liter bottle and fill it with water
  • Put in a plant which the fish and shrimp will eat
  • Put the bottles in a place where there is little sunlight
  • Hope that it would stay there for a long time.
Hypothesis;
I think that the fish would live for 15 days (half a month) because as far as I saw the 1.5 liter bottle, the water didn't grow yellow just yet. If they die, the reason might be that they are losing oxygen. 

Reason of jars turning yellow;
The reason is that there are too much carbon dioxide which indicates the bromothymol blue changing it into yellow.

How plants and animals depend on each other?
If animals doesn't have any plants to eat, they die. In addition, if the animals doesn't fertilize (by dung) the plants would die and the whole world would become extinct

What will happen in 1 week?
In one week of the animals that are living inside the bottle might die because there is no sunlight to produce them oxygen.

When did the fish die?
It died on the date Monday 4th July 2016. R.I.P


I think that the fish died because carbon dioxide could be in the bottle which contained the fish or shrimp. The groups that have their fish alive, their bottle is different from ours by; the weed is less than the first time we put it in.

If I were to do the experiment again, I would change by opening the bottle and putting more weed in it to keep the fish survive even longer and changing the water every 5 days.

1.  What do you think kills the fish/shrimp--oxygen or temperature of water,  why?
- I think that oxygen might affect the fish by them breathing out carbon-dioxide.
- Temperature might affect the plant that produces oxygen and food (they might not have enough sunlight) and not doing their job (photosynthesis).


2.  Did you find anything interesting in the lab?
- I like to do experiments and I found an interesting fact; in the window in the lab, it looks like there is enough sunlight to all of the bottles but there are only some which survives. Because there are sunlight to support the plant and the fish.


3.  What other things could kill the fish?
- In some other bottles, there are some fungus in the bottle, that might be another fact that can kill the fish. As far as I observed the bottle, there is only one in ten bottles that have fungus in them.
