1. I. Introduction
   1. Problem Background

The pollution  of environments  that polluted can make bad effect  for organism who live into them.

1. Problem Formula

Can detergent influenze the survivaal of fish?

1. Purpose

We know effect of detergent to fish life

1. II. Theory

Biology Theories

The water can be polluted if contamining with substance, so can’t use by organism around them.

Chemistry Theories

The water without pollution (pure water) consist of H2O

The water have PH more or less than 7, can make bad effect for organism that use it.

III. Experiment Method

1. Kind of Experiment

Observation

1. Experiment Variables

Manipulation variables  : Consentration of the detergent

Control variables                      : Volume of water, fish, the kind of detergent

Response variables                   : How long fish can life in water that

containing detergent

1. Design Experiment

1. Experiment Procedure

Bottle I             : See 2 golden fish that plunged into pure water.

Bottle II                        : See two golden fishes that plunged into water that

mixed with 0,25  gram of detergent

Bottle III                      : See two golden fishes that plunged into water that

mixed with 0,5 gram of detergent

IV. Result of Experiment

1. Result of Observations

1. Analyzing

According to the table above we can see that golden fish that plunged into pure water can alive.

And the fishes that plunged into detergent solution, life in relative shorter  time, depend to the mass of detergent.

1. Discuss
   1. A.   Our prediction was correct.

B.  This part is hyphothesis

1. We use a several steps, there are :
   1. Formulate the problems
   2. Observation
   3. Hyphothesis
   4. Experiment
   5. Conclutions
   6. As comparator.
   7. Because we guessing it from several theories.
   8. Yes, our experiment is a way of proving our hyphothesis.

1. Hyphothesis that we made have synchronous  with our observation.
2. Description of Scientific Method
   1. Formulate the problems

We found a problem about water pollution and we arrange them become one topic.

1. Observation

This topic must be tested by observating problems above. We can review several theories from literatures, opinion from packard, or last experiment by other reseachers.

1. Hyphothesis

After we do the observation, result from this observation be proccessed become hyphothesis. We can arrange zero hyphothesis, or alternative hyphothesis.

1. Experiment

For testing our hyphothesis, we must do experiment. By attent ways of experiment and ethic code of experiment such as : honest, objective, think smart, and etc.

1. Conclutions

Then, after we do experiment. If our experiment are synchron with hyphothesis so we can make a conclution. But if our experiment aren’t synchron, we need to retry our experiment.

1. V. Conclutions

If the mass of detergent become higher, then the time of deathing fish become faster.

Organism need  the  clean environment to life

1. I. Introduction
   1. Problem Background

Green house making temperature on the earth is hot, and the climate in our word showing uncertain. It’s can happen because unbalancing concentration of CO2 in athmosphere. This effect come from smoke by industrial  machines, from vehicles engine, cigarette, and so on.

1. Problem Formula

What causes of Green House Effect?

How influenze “Green House Effect” to organisms in the world?

How to solve Green House Effect?

1. Purpose

We know the influenze of plant vegetation with Green House Effect

We can explain about Green House Effect.

We understand about influenzes Green House Effect to the organism.

We can decrease risk from Green House Effect.

1. II. Theory

• The earth constantly receive energy, most of them come from sunlight and several part from this earth (Holum , 1998 : 237)
• A Part of energy that absorbed is radiated again become infra red radiation (Petrucci and Harwood, 1997:260)
• Carbondioxide are green house gases that important and significant causes in green house effect (Setiono, Masjhur, and Alisyahbana, 1998: 42).

III. Hyphothesis

• The term of enviromnent be influenze by vegetations.
• The plants can reducting warming of environment.

IV. Experiment Method

1. Kind of Experiment

We did experiment that followed by Scientific Method. Beside it we also use process skills such as : observing, inferring, predicting, communicating, measuring and etc.

1. Experiment Variables

Manipulation variables  : The treatment without the plant

Control variables                      : The first temperature

Response variables                   : Final tempearature in room object of

experiment.

1. Design Experiment                                                                    Glass

A B

Thermometer

Equipments	Materials
Thermometer          2 Glasses                   2 Plastic media         2 Plants (depend for needs)

1. Experiment Procedure
   1. Prepare and arrange the equipment like to picture above
   2. Give a mark A to object without plant, and give mark B to object with plant.
   3. Put both to lighten place, and every 10 minutes see object’s temperature. (the duration of this experiment are 2×10 minutes).

1. V. Result of Experiment
   1. Result of Observations

1. Analyzing

From this picture above we can see thet object room without plant is warmer than object room with plants. It’s can be sketch to diagram below.

The chart of comparing term.

1. Discuss

Our hyphothesis is true. We do this experiment as sample of our environment, we use analogical methods such as : plastic as environment that containing CO2 in athmosphere, and the plants as vegetations in our environment. And we use thermometer for measuring a term in object. We make conclution according to foundation theories, hyphothesis, and really experiment.

1. Description of Scientific Method
   1. Formulate the problems

We found a problem about Green House Effect and we arrange them become a problem background, from problem backgroud we posing some questions and search experiment purpose.

1. Observation

Using our senses for review a sample of warming environment. Before we do it, we need some theories from Packard or literatures that relevant for answering the question above and as foundation to arrange hyphothesis.

1. Hyphothesis

Before doing experiment we arrang a hyphothesis that based from our question in order to carry investigation and obtain evidence that shows whether the hyphothesis is true or false and maybe finally hyphothesis can be used to set a conclution after do experiment.

1. Experiment

We doing experiment for testing hyphothesis is true or false. While we do it we must objective thingking and not manipulating data. From our experiment we arrange result, analysis, and chart (if needs).

1. Conclutions

Finally after analizing data, we can make conclution. This conclution is related to hyphothesis. We recall that hyphothesis is possible explanation that is tested during experiment. After carried out the procedure we can determine our experiment is true or false.

VI. Conclutions

• The Green House Effect can make temperature in our earth increase so causing Global Warming.
• Negative effect for Green house effect are : make term in our environment increase significantly.
• But the Gren House Effect also can make positive impact for farming in Eropa when spring season.
• The plants can decreasing the term because can reducting CO2 and change by O2.
