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
They learn from other scientists and what they have done. Scientists conduct their own experiments.
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.
Observations can include what you: - See - Smell - Hear - Feel - Taste
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.
Biological Science- the science of living things -Botany -Ecology -Zoology
Physical Science- Science of matter and energy -Physics- forces and energy -Chemistry- matter and its changes
Science of the Earth -Geology -Astronomy -Meteorology
Technology is the application of science for practical, everyday uses. Engineers apply scientific knowledge to design and create things for people to use.
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
Qualitative statements describe something you see using words. Quantitative statements describe something you see using mathematical equations. - Ex. A= l x w
Models can be drawn on paper or made from real objects. Scientists use computer models to study complicated events and to make predictions.
