13. 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

14. Images from Mars…What do they tell us about what types of scientists were needed?

15. 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?

16. 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…

17. Examination of Meteorite Impact Hypothesis Video

18. 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)
