## SCIENCE PROJECT

Today we have finish experiments of volume, density and mass, so what we did was we have sample numbers and weigh it on the measuring stand.

This is our result.
Simple numbers  Heigh  Volume  Density
7             100       245    0.40816
6              50       110.9  0.45085
5              50       110.7  0.45167

The environment that affects other social  issues

(Cut the tree)
1.When I cut the tree the environment will bad because when have the floods the tree will don't help anything.
2.When I don't cut the tree and I plant the tree more it will be well more than cut because when have the flood the tree will help.

The tree that they help is peaceful and it helps to be slow (water).
3.When have some many trees is good because it will help some animals because the animals can be life there.
4. It will have more oxygen when have many trees.
(tree mean oxygen-oxygen means life)

The Effect of Gravity on speed

 Height Time to travel 5 meters Distance travelled 20 4.38 - 20 4.41 - 20 4.34 - 40 5.87 - 40 4.27 - 40 5.03 - 60 5.25 - 60 5.49 - 60 5.61 - 80 7.19 - 80 7.21 - 80 7.18 -

Observation: 20 height go slow
40 height go faster than 20 height
60 height go faster than 20 and 40
80 height go fastest

1.Describe how the ball rolls off the ramp at each height- discuss the effect of bouncing or other factor.
Ans- 20 height the ball go straight line
40 height the ball go same with 20
60 height the ball go awry
80 height the ball go bounce
2.Discuss what is the fastest speed reached and any factors that could improve this.
Ans- Yes
3.Does the ball travel in the straight line, why or why not.
Ans- Yes because the ball will find the optimal  angle to maximize acceleration, so it travels the farthest and/or the fastest.

I think cloud is beautiful and it can make good.

status is เป็นเมฆชั้นหนา

MY Essay
In Panyarat High School .I think my school is not good not bad .I think some friends good some friend bad but it ok.I think my scores is worse .And I will do good in exam more.

## Global Warming Causes

### Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. See the pie chart for a breakdown of heat-trapping global warming emissions by economic sector.

Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

Global warming 'cure' found by scientists. A "technical fix" that could stop global warming by taking billions of tons of carbon dioxide out of the atmosphere and save the coral reefs from being destroyed by acidification has been developed by scientists.

The grass is a producer which eat the bird which is a consumer. Energy come from producer by photosynthesis and the consumer take the energy by eating the producer.

### Symbiosis

Symbiosis
Symbiosis is the interaction between two different organisms living in close physical association, typically to the advantage of both.

It is separated into 3 main groups.

Commensal - One side get benefit one side don’t get and not harmful

Parasitic - one side got benefit one side don’t and get harmful.

Mutualistic-Both side get benefit.

## Commensalism

Commensalism is an association between two different species where one species enjoys a benefit, and the other is not significantly affected.

## Parasitism

Parasitism is an association between two different species where the symbiont benefits and the host is harmed.

## Mutualism

Mutualism or interspecies reciprocal altruism is a relationship between individuals of different species where both individuals benefit.
