Scientists perform experiments to:- Find a new aspect of the natural world- To explain known phenomenon- To check the results of other experiments- To test predictions

How Science Takes Place

They learn from other scientists and what they have done.

Scientists conduct their own experiments.

How Do Scientists Answer Questions?

Before you can begin an experiment you need to make a plan.

Scientists write their plan They list the equipment they will need to

conduct the experiment Scientists make tables to record their data

and keep it organized.

Scientists Plan Experiments

Observations can include what you:- See- Smell- Hear- Feel- Taste

Scientists Observe

It’s important that you repeat the experiment to see if you get similar results.

At the end of an experiment you may have more questions. You can go back and test to get answers to your new questions.

Scientists Confirm Results

Biological Science- the science of living things-Botany-Ecology-Zoology

The Branches of Science

Physical Science- Science of matter and energy-Physics- forces and energy-Chemistry- matter and its changes

The Branches of Science

Science of the Earth-Geology-Astronomy-Meteorology

The Branches of Science

Technology is the application of science for practical, everyday uses.

Engineers apply scientific knowledge to design and create things for people to use.

Science and Technology

Law- describes a process in nature that can be tested by repeated experiments.

Theory- explains how a natural process works. -Explains observations clearly-Experiments that explain the theory need to be repeatable-You need to be able to predict results using a theory

Scientific Laws and Theory

Qualitative statements describe something you see using words.

Quantitative statements describe something you see using mathematical equations.- Ex. A= l x w

Qualitative vs. Quantitative

Models can be drawn on paper or made from real objects.

Scientists use computer models to study complicated events and to make predictions.
