What is science?Look in the dictionary…What is the difference between social and
natural science?
What is unique about mathematics?It is a universal
language… considered the “purest” science.
The main branches of Natural Science…PhysicsChemistryBiology
What makes Environmental Science?

Team of ScientistsTypically we need a
team of scientists to solve problems and answer questions in science.
Let us consider the Mars Exploration Rover (MER) Mission from 2005…
Rovers Spirit and Opportunity
• Images from Mars…What do they tell us about what types of scientists were needed?
Scientific Method (5 Steps!)Can be applied to any problem, no matter
how simple.State the ProblemGather InfoForm a HypothesisTest the Hypothesis
Control and a variableState the Conclusion
Do we have a Theory? How is this different from a Law
Examples?
Design an experiment using scientific method…You own a trucking company and have to
transport a series of gasses and need to determine which gases are flammable. (Air, Helium, Hydrogen, CO2)
Design an experiment…
Examination of Meteorite Impact Hypothesis
Video
How do we know it happened?State the Problem- How did the dinosaurs go
extinct?Gather Info- Look for meteorite impact areas?
Other Causes?Form a Hypothesis- Meteor hit the Yucatan
Peninsula because high levels of iridium and deformed quartz.
Test the Hypothesis- Check for iridium in soilsControl- test random soil samples around the EarthVariable- test soil at impact site
State the Conclusion100x’s iridium levels, impact crater, caverns = MIH
(Meteorite Impact Hypothesis)
Barringer Crater in AZ
4000 Feet in diameter created by a meteorite approximately 50 meters across.
