BiologyMs. Nguyen Chapter 1: What is Science


THINK ABOUT IT Where did plants and animals come from? How did I come to be?

Humans have tried to answer these questions in different ways. Some ways of explaining the world have stayed the same over time. Science, however, is always changing.


I. Science Is…

1. Science is an organized way of gathering and analyzing evidence about the natural world.

a. For example: When student researchers use science to answer the question how can a CHS student use technology to benefit study time.

1. Deals only with the natural world.

2. Information collected and organized in accordance to patterns and connections among events.

3. Explanations that are based on evidence.

4. All explanations are tested.

A. Define Science:

B. Scientific means:


Bell Ringer: 1) Find a partner in front or behind you.2) Exchange Key Notebooks.3) Review your partner’s key:

1) Does he/she have all the terms (19)?2) Is there a visual for all the terms?3) Are the visuals colored and are the terms cut out?4) Write your comment in the Peer Review Section on the score sheet and initial

it. 4) Exchange Keys.


1. Provide natural explanations for events in the natural world

2. To use those explanations to understand patterns in nature.

3. To make useful predictions about natural events.

1. Continuous study about how life has evolved.

a) Bio = lifeb) logy (ology)= study

1. Most scientific discovery raises more questions than it answers.

2. Constant change = advance.

3. Questions and predictions target the natural world.

C. Goals of science:

D. Define Biology?

E. Why does science continue to change?

Summary: Explain how something is considered scientific?


II. Scientific Methodology: The Heart of Science

1. Scientific methodology involves:

a. observing and asking questions

For example: Why do marsh grasses grow to different heights in different places?

A. The core of scientific methodology?

Lesson Overview What Is Science?b. making inference (logical interpretations based on what is already known) and forming hypotheses (scientific explanation for a set of observations that can be tested in ways that support or reject it)

c. conducting controlled experiments: • In a controlled group temperature, light, time,

and availability of nutrients MAY change! • In an experimental group than the temperature,

light, time, and availability of nutrients MAY NOT change

Lesson Overview What Is Science?d. collecting and analyzing data:

There are two main types of data: quantitative data and qualitative data.

• Independent Variable: variable that is deliberately changed (Y- axis)

• Dependent Variable: observed and that changes respond to. (X- axis)

Lesson Overview What Is Science?e. drawing conclusions: experimental data as

evidence to support, refute, or revise the hypothesis being tested, and to draw a valid conclusion

Summary: Explain the scientific method steps


Think- Pair-ShareBell Ringer

Directions: Read the following experiment to determine who is the controlled group, experimental group, independent variable, and dependent variable.

Smart Pill Experiment

Who is part of the Control Group and

why?

Who is part of the Experimental

group and Why?

What is the Independent Variable?

What is the dependent Variable?

The Smart Pill Experiment! One side of the class will get a smart pill and the other side will get a pill that looks like the smart pill, but it is just a sugar pill. (Placebo) After a week of taking the pill, Ms. Nguyen will give Chapter 1 test.

Lesson Overview1.2 Science in Context


III. Exploration and Discovery: Where Ideas Come From

1. Curiosity, skepticism, open-mindedness, and creativity help scientists generate new ideas.

A. What scientific attitudes help generate new ideas?


IV. Communicating Results: Reviewing and Sharing Ideas

1. Scientists share their findings with the scientific community by publishing articles that have undergone peer review.

2. Enables scientists in other fields to ask new questions or to gather data in new ways.

A. Define peer review?

B. Why is peer review important?


V. Scientific Theories

1. A well-tested explanation that unifies observations and hypotheses and enables scientists to make accurate predictions about new situations.

2. A useful theory are thoroughly tested and supported by many lines of evidence.

3. No absolute truth.

A. Define scientific theory?

VI. Science and Society

1. A particular preference or point of view that is personal, rather than scientific.

2. Sometimes scientific data can be misinterpreted or misapplied by scientists who want to prove a particular point.

A. Define Bias

Summary: How are scientific theories created and what are the advantages and disadvantage?


Lesson Overview1.3 Studying Life


THINK ABOUT IT What makes something living?


VII. Characteristics of Living Things

1. Living things are made up of:

a. basic units called cells

(the smallest and most complex and highly organized fully alive structure.)

b. based on a universal genetic code

c. obtain and use materials and energy

d. grow and develop

e. reproduce

f. respond to their environment

g. maintain a stable internal environment

h. change over time

A. What characteristics do all living things share?


1. No single characteristic is enough to describe a living thing.

2. Some nonliving things share one or more traits with organisms.

3. Some things, such as viruses, exist at the border between organisms and nonliving things.

B. Biology is the study of life, but what is life?


1. All organisms store the complex information they need to live, grow, and reproduce in a genetic code written in a molecule called DNA. (deoxyribonucleic acid)

2. That information is copied and passed from parent to offspring and is almost identical in every organism on Earth.

C. Living things are based on a universal genetic code. de·ox·y·ri·bo·nu·cle·ic acid


1. All Living things grow and develop.

2. During development, a single fertilized egg divides again and again.

3. As these cells divide, they differentiate, which means they begin to look different from one another and to perform different functions.

D. Development:


1. A stimulus is a signal to which an organism responds.

For example, some plants can produce unsavory chemicals to ward off caterpillars that feed on their leaves.

E. Living things respond to their environment.


1. produce new similar organisms.

2. Most plants and animals engage in sexual reproduction, in which cells from two parents unite to form the first cell of a new organism.

3.Other organisms reproduce through asexual reproduction, in which a single organism produces offspring identical to itself.

For example: Beautiful blossoms are part of an apple tree’s cycle of sexual reproduction.

F. Living things reproduce


1. Homeostasis- all living organisms expend energy to keep conditions inside their cells within certain limits..

For example, specialized cells help leaves regulate gases that enter and leave the plant.

1. Metabolism- the combination of chemical reactions through which an organism builds up or breaks down materials.

For example, leaves obtain energy from the sun and gases from the air. These materials then take part in various metabolic reactions within the leaves.

G. Living things maintain a relatively stable internal environment even when external conditions change dramatically

H. Living things obtain and use material and energy to grow, develop, and reproduce.

Summary: What makes something living versus nonliving?


Bell Ringer:

1.Glue/staple your homework: Page 1.A onto the first available Left Side PAGE of IAN!

2. Check your answers with a partner and correct the incorrect answers.


1. Many living things consist of only a single cell and are called unicellular organisms.

2. Plants and animals are multi-cellular. Cells in multi-cellular organisms display many different sizes, shapes, and functions.

1.The information coded in your DNA is similar to organisms that lived 3.5 billion years ago.

For Example: The DNA inside your cells right now can influence your future—your risk of getting cancer, the amount of cholesterol in your blood, and the color of your children’s hair.

A. Cellular Basis of Life

B. Information and Heredity

VIII. Main themes in Biology


1. Life requires matter that serves as nutrients to build body structures, and energy that fuels life’s processes.

2. Some organisms, such as plants, obtain energy from sunlight and take up nutrients from air, water, and soil.

3. Other organisms, including most animals, eat plants or other animals to obtain both nutrients and energy.

4. All living things on Earth is in a web of interdependent relationships.

C. Matter and Energy


1. All living things reproduce. Newly produced individuals grow and develop as they mature.

2. During growth and development, generalized cells typically become more different and specialized for particular functions.

3. Specialized cells build tissues, such as brains, muscles, and digestive organs, that serve various functions.

D. Growth, Development, and Reproduction


1. Organisms use structures that have evolved into different forms as species have adapted to life in different environments

E. Structure and Function .


1. All organisms are composed of:

a. a common set of carbon-based molecules

b. store information in a common genetic code

c. use proteins to build their structures and carry out their functions.

2.Evolutionary theory explains both this unity of life and its diversity.

F. Unity and Diversity of Life


1. All forms of life on Earth are connected into a biosphere.

2.Within the biosphere, organisms are linked to one another and to the land, water, and air around them.

3.Relationships between organisms and their environments depend on the cycling of matter and the flow of energy.

G. Interdependence in Nature

Summary: In your own words, recap the main themes of Biology.
