#2. How many tardies can you have and NOT receive EMD or other punishment?

Write answers in complete sentences. You do not have to write the questions.

What is Science?

• Science – means “to know”• What is a goal? • (student responses)• Goal of science • Is to understand the world around

us…

Learning About the World

• Science is a way of learning more about the natural world.

• Scientists want to know why, how, or when something occurred.

• This learning process usually begins by keeping your eyes open and asking questions about what you see.

Asking Questions

• Science can attempt to answer many questions about the natural world, but some questions cannot be answered by science.

• Questions about art, politics, personal preference, or morality can’t be answered by science.

• Science can’t tell you what is right, wrong, good, or bad.


Possible Explanations

• Science can answer a question only with the information available at the time.


Possible Explanations • As new information becomes available,

explanations can be modified or discarded and new explanations can be made.


WEDNESDAY - August 17, 2011 - Opener #2 1. What are some things that you were able to determine about items in your box from yesterday (or today 7th period)?

2. What could you infer or hypothesize about items in the mystery box?

3. What types of experiments and tests could you do to find out more about the items in your box?

4. What is something that you might never be sure about in your box unless it was actually opened?

Questioning and Observing

• Investigations often begin by making observations and asking questions.

22Science in ActionScience in Action

ACTIVITY

Facts, Theories, Laws…• Facts – verified by measurement,

observation, or other method.• Example with and w/o Mystery Boxes…• Scientific Theory – logical explanation

for events which occur in nature…• Examples: Cell theory, theory of

evolution, ... • Sci. theory vs. theory in other apps.

Scientific Theories

• An attempt to explain why a pattern observed repeatedly in the natural world is called a scientific theory.

• Theories in science must be supported by observations and results from many investigations. They tell WHY...

• They are the best explanations that have been found so far.


Scientific Theories

• Theories can change. As new data become available, scientists evaluate how the new data fit the theory.

• If enough new data fails to support the theory, the theory can be changed to fit the new observations better.

• Scientific theories are always being questioned and examined. To be valid, a theory must:• explain observations• be repeatable• be predictable

Scientific Laws

• A rule that describes a pattern in nature is a scientific law.

• For an observation to become a scientific law, it must be observed repeatedly.


• IT TELLS WHAT was observed as pattern - often mathematical equation showing the pattern or formula...

Scientific Laws

• A law, however, does not explain why, for example, gravity exists or how it works.

• A law, unlike a theory, does not attempt to explain why something happens. It simply describes a pattern.

• Example: Law of gravitation free fall...• Newton’s Laws...


Skip -Examples/Illustrations of Laws

• Examples of Laws: Law of gravity…• Illustration with law of conservation of

energy with pendulum (tetherball) and/or rotation of chair with weights…

• Note to me...• Next is Phys.Sci.S1.1 clips along with

1.1 What Is Science?

In July 1997, the six-wheeled Sojourner rover became the first robot to explore planet Mars. Sojourner was built to answer questions about the nature of Mars.

Science involves asking questions about nature and then finding ways to answer them.


How does the process of science start and end?

Science From Curiosity


Have you ever checked what was living at the bottom of a pond?

Taken off the cover of a baseball to see what was inside?

Tried putting more chocolate or less in your milk to find out how much would give the best flavor?

These are all examples of curiosity, and curiosity is the basis of science.



Science begins with curiosity and often ends with discovery.



• In some experiments, observations are qualitative, or descriptive. (ex. bubbles, makes blue solid ppt...)

• In other experiments, observations are quantitative, or numerical. (It produced 5 grams, speed was 20 km/hr...

• Some questions—for example, how the universe began—cannot be answered by direct observations and measurements but only by other kinds of evidence.

Curiosity provides questions, but scientific results rely on finding answers.



Science is a system of knowledge and the methods you use to find that knowledge. The goal of science is to expand knowledge.

What is the difference between pure science and applied science?

Technology is the use of knowledge to solve practical problems. The goal of technology is to apply knowledge, thus applied science ...

Science and Technology


The telephone was invented in 1876. By 1927, it was possible to make a phone call from New York to London. The first mobile telephones, invented during World War II, paved the way for modern cellular phones. At each step, new science was applied to improve the technology of the telephone.


What is the relationship between science and technology?

Science and Technology

Science and technology are interdependent. Advances in one lead to advances in the other.


What are the branches of natural science?

Branches of Science: Natural vs. social sciences


Natural science is generally divided into three branches: physical science, Earth and space science, and life science (biology).

Branches of Science - Social vs. Natural



• Chemistry is the study of the composition, structure, properties, and reactions of matter.

• Physics is the study of matter and energy and the interactions between the two through forces and motion.

Physical science focuses on nonliving things.


• Geology is the study of the origin, history, structure, and systems of Earth.

• Astronomy is the study of the universe beyond Earth.

The application of physics and chemistry to the study of Earth is called Earth science.



• Biology includes the physics and chemistry of living things, as well as their origin and behavior.

• Biologists study the different ways that organisms grow, survive, and reproduce.

The study of living things is known as biology, or life science.



• Much of biology involves changes that are part of chemistry, while much of chemistry is defined by interactions that are part of physics

• Biophysics is a growing area of physics that applies physics to biology.

There is overlap between different areas of science.
