Science and The Scientific Method 1.1 & 1.2

Curiosity Killed the Human…or did it? Humans are curious. Curiosity leads to questions. Which questions? Begins with Curiosity and ends with Discovery

Science and Technology Technology – use of knowledge to solve practical problems Science and Technology are interdependent Advances in one lead to advances in another Examples?

Branches of Science Natural Science divided into 3 branches Physical Physical, Earth/Space, and Life Physical Chemistry & Physics Define Earth/Space Geology & Astronomy Life Biology

Branches of Science Not Defined….Always Overlap Examples

Big Ideas Space and Time Universe is very old and very big 13.7 Billion years old Observable universe is 700 million billion billion meters in diameter

Big Ideas Matter and Change Forces and Motion Energy Matter has volume and mass and small bits of universe has matter Made of atoms (building blocks) Forces and Motion Forces cause change in motion Energy Different forms of energy Examples?

Science Changes Constantly changing with NEW EVIDENCE Some ideas out there now will be adjusted and changed as new technology and evidence appears

Scientific Method What is the goal of the scientific method?

Scientific An organized plan for gathering, organizing, and communicating information is called a scientific method. The goal of any scientific method is to solve a problem or to better understand an observed event.

Here is an example of a scientific method Here is an example of a scientific method. Each step uses specific skills. The order of steps can vary. Sometimes you will use all of the steps and other times only some of them.

Making Observations Scientific investigations often begin with observations. An observation is information that you obtain through your senses. Forming a Hypothesis A hypothesis is a proposed answer to a question.

Drawing Conclusions A conclusion describes how facts apply to a hypothesis.

Developing a Theory A scientific theory is a well-tested explanation for a set of observations or experimental results. Once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory

Review Making Observations Scientific investigations often begin with observations. An observation is information that you obtain through your senses. Forming a Hypothesis A hypothesis is a proposed answer to a question.

Review Testing a Hypothesis In an experiment, any factor that can change is called a variable. The manipulated variable causes a change. The responding variable changes in response to the manipulated variable. A controlled experiment is an experiment in which only one variable, the manipulated variable, is deliberately changed at a time.

Review Drawing Conclusions A conclusion describes how facts apply to a hypothesis. Developing a Theory A scientific theory is a well- tested explanation for a set of observations or experimental results. Once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory.
