Types of Clouds

☁ Types of clouds ☁

Cumulus clouds

Cumulus clouds are white puffy and fluffy clouds which usually means good weather. They look like pieces of floating cotton. Unlike Cirrus and Stratus which doesn't mean change in weather is coming or rainfall. They are 1000 meters high in the sky. 












Cirrus clouds


Cirrus clouds are thin, flat and featherlike clouds of ice crystals in the atmosphere which usually means a change in weather is coming. Unlike any other clouds, they are thin and flat, not fluffy like cumulus clouds. In addition, they are very wispy and they are 6000 meters high.

Stratus Clouds
Cirrus clouds are sheets of low, grey clouds that bring light snow, hail or rain. They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or very near the ground, and then we call them fog.

My Highlights this year 

This year my highlights are that Physics about speed, time and velocity. These I am looking forward to getting better at it. Next year I am looking forward to many things, but I have no idea what it is now.

The effect of gravity on speed

Add Science Analysis
Procedure:
1. Put the ramp against the seat of a chair. Place the ramp and chair so that the ramp points towards the hallway. Have your teammate on the other end of the hallway.
2. Place the ball bearing at the top of the ramp.
3. Lift the ramp 20 cm and release the ball bearing.
4. Time how long it takes to travel in 5 meters.
5. See how far it will go.
6. Repeat the experiment three times for each height then do 40 cm, 60 cm and 80 cm.

Analysis (questions):
1. Describe how the balls roll off the ramp at each height - discuss the effect of bouncing other factors.

= The ball bearing rolled diagonally off the ramp and went very far (20 cm). The ball bearing rolled, also diagonally and not the furthest (40 cm). The ball bearing rolled, 3 times, almost vertically (60 cm).

2. Discuss what is the fastest speed reached and any factors that could improve this.

= The fastest speed reached 4.50 seconds and the way we can improve this, is having a smoother ramp which will make the ball roll faster in a rate, because there is less friction. But if we have a rough ramp the ball bearing will have more friction and will roll slower than the smoother ramp.

3.  Does the ball travel in a straight line, why or why not?

= The ball doesn't travel in a straight line which there are 2 factors, the first reason is that we placed it in where the ball rolls diagonally, the second reason is that there is wind which pushes the ball to the right or left.

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 🔎.
