Team of Scientists
 Typically 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
Answer this question in your
notes…
 What types of scientists would you need on
a expedition to Mars?
 Please Explain why for each…
• 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 Problem
 Gather Info
 Form a Hypothesis
 Test the Hypothesis

Control and a variable
 State 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 soils


Control- test random soil samples around the Earth
Variable- test soil at impact site
 State the Conclusion
 100x’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.
