__The Science of biology__
For a long time people have wondered about living things; how many there are, where they live, how they relate to each other. The concepts, principles, and theories that allow people to understand the natural environment form the core of **biology**, the study of life. Biology is the study life on earth, though usually focusing on one specific aspect. When you study the different types of life you will ask many questions. Biologists study the diversity of life

Many people study of biology simply because they love it. Since no living things live in isolation, they study of biology must include the investigation of living interactions. Human existence is closely intertwined with the existence of other organisms living on Earth as well. An **organism** is any living thing. Many organisms are used by humans, referred to as raw materials. Raw materials that supply us would be wood, cotton and oil.

They study the future of biology. The research can produce new medical treatments, disease prevention. Teach us new things about ourselves, it can help us preserve things. Animals and plants can have a better future.

Characteristics of Living Things
There are five things. How a living thing is classified: 1. Have an orderly structure, 2. Produce offspring, 3. Grow and develop 4. Adjust to changes in the environment.

Living things have an orderly structure, or **organization**. They have organized cells. Every cell contains DNA which provides the information needed to control the organism’s life processes. Cells are the basic unit of life.

Living things produce offspring in **reproduction**. To reproduce, animals must be of the same [|species]. **Growth** causes an increase in the amount of living material and the formation of new structures, while **development** is the different stages of life each organism progresses through.

Organisms live in a constant interface with their surroundings, or **environment**, which includes the air, water, weather, temperature, any other organisms in the area, and many other factors. Anything in an organism’s external or internal environment that causes the organism to react is a **stimulus**. Reaction to stimulus is a **response**. Regulation of an organism’s internal environment to maintain conditions suitable for its survival is called **homeostasis.** The source of stimulus is **energy**, which is the ability to cause change.

Organisms have inherited structure, behavior, and internal processes that enable the organism to respond to environmental factors and live to produce offspring, or **adaptations**. Adaptations cause **evolution**; the gradual change in a species over time. Here is a movie about polar bears and how they live in their envoirnment.[|polar bears]

Review vocabulary:
Environment: an organism’s surroundings

New Vocabulary:
Scientific methods, Hypothesis, Experiment, Control, Independent variable, Dependent variable, Safety symbol, Data, Theory

Observing and Hypothesizing:
Scientists gather information and answer questions using **scientific methods**. They use the data collection to make a **hypothesis**, which is an explanation for a problem that can be formerly tested. Some methods vary based on what you’re experimenting on.Here is a movie of a well performed experiment. [|experiment movie]

Experimenting:
An **experiment** is an investigation that tests a hypothesis by the process of collecting information under controlled conditions. Experiments use a **control**, which is the standard that the results are compared to. They use **independent variables**, which affect the outcome of the experiment, and **dependant variables**, which are changed by the independent variables. When experimenting, safety symbols are used to maintain safety. A **safety symbol** is something that warns you about dangers that may exist from chemicals, electricity, heat, or procedures you will use. Information obtained from investigations is called **data**. A hypothesis that is supported many times by different experiments may become a **theory**.

Review vocabulary:
Experiment- procedure that testes a hypothesis by collecting info

New vocabulary:
Ethics Technology

Kinds of information:
The two kinds of information are **quantitative**, which is measured in exact terms like temperature or length, or **qualitative** which is observed, like color or shape.

Science and society:
Science has to follow a code of ethics. **Ethics** refer to the moral principles and values held by humans. **Technology** is the application of scientific research to a society needs and problems. Technology’s purpose is to solve problems, but it can also create them. A good example is fertilizer, which helps crops grow better but also pollutes water.
