Essential questions
Essential Questions

  • What is science?

  • What methods do scientists use?

  • What are the branches of Earth science?

Science is
Science is

  • A way of learning about the natural world and the knowledge gained through that process.

  • Science comes from a Latin word that means “knowing”.

  • Scientific inquiry is the diverse ways in which scientists explore problems and seek to answer questions about the natural world.

Thinking like a scientist
Thinking Like a Scientist

  • Observation involves using sight, hearing, smell, and sometimes taste to gather information.

  • Inference is an interpretation based on your observation and prior knowledge.

Scientific methods
Scientific Methods

  • Scientific methods generally include posing questions, research, developing and testing hypotheses, and drawing conclusions. Scientists often test hypotheses by conducting controlled experiments.

  • Posing questions – Which brand of popcorn will have the fewest kernals?

  • Research – internet, encyclopedias, etc.

Developing hypotheses
Developing Hypotheses

  • A hypothesis is a possible explanation for observations that relate to a scientific question.

  • Tested by observation or experiment.

  • Educated guess -

  • Use “if” and “then”

  • If five bags of each brand of popcorn is cooked, then Orville Redenbacher's popcorn will have the fewest kernels.

Designing a controlled experiment
Designing a Controlled Experiment

  • Controlled Experiment – how one particular variable affects the outcome of the experiment.

  • Variable is one of the factors that can change in an experiment.

  • Microwave 3 brands of popcorn. This will be done with 4 bags each brand.

Testing hypotheses
Testing Hypotheses

  • “Experimenting” at least 3 times or 14 days.

  • Earth processes are often observed for millions of years!

  • “Forever Young” – journals were kept on how Mel Gibson stayed young.

Collecting and interpreting data
Collecting and Interpreting Data

  • Data – facts, figures, and other evidence gained through observation

  • CSI – crime data

  • Measurements

  • Analyze the data to see if it supports their hypothesis.


  • Enables scientists to record what they observe in a way that others can understand easily.

  • Scientist use a worldwide system

  • International System of Units – SI units

  • Use metrics – cm, m, mg, liters

Drawing conclusions
Drawing Conclusions

  • Do not use crayons or markers

  • Making a conclusion based on the data from your experiment.

  • Relate to the hypotheses…..

  • My hypothesis was incorrect. Wal-Mart brand had the fewest kernels and tasted the best.

Models simulations
Models & Simulations

  • A simulation is a model that imitates something in the real world.

Scientific theories
Scientific Theories

  • A well-tested scientific concept that explains a wide range of observations.

  • When theory tests fail, scientist change the theory or abandon it.

Laboratory safety
Laboratory Safety

  • Symbols alert you to needed precautions, such as wearing goggles to protect your eyes.

Technology and the internet in earth science
Technology and the Internet in Earth Science

  • Two ways that technology helps scientists

    • Collect data

    • Helps them to communicate their discoveries to other scientists and to the public.

Branches of earth science
Branches of Earth Science

  • Earth science – knowledge about Earth and its place in the universe.

    • Geology

    • Oceanography

    • Meteorology

    • Astronomy


  • Geology – study of the solid Earth.

  • Oceanography – study of Earth’s oceans.

  • Meteorology – study of Earth’s atmosphere.

  • Astronomy – study of the universe beyond Earth.

  • Environmental scientists – study the environment and it’s resources.
