[Music] I wonder a lot about science it's everywhere look around can you see it sure science is a body of knowledge about the natural world you can read about what we know about science about Earth space Life Energy and so much more but did you know that you can do science it's how we create science knowledge to begin with there's different ways of doing science but science always starts with something in the natural world that one observes and wonders about over time you find that the world is predictable and consistent and that evidence can be tested and verified think about forecasting our weather forecasts are pretty good in fact they've never been more accurate that's because the science and scientific tools like Radars and computer hardware and software have been tested and improved upon since studying weather began just look at how far we've come 1850 1950 2000 2015 in 2050 weather forecasting will be better still science knowledge is always tentative and uncertain though sometimes a lot sometimes just a smidget but tentative and uncertain nonetheless think about weather again a weather forecast based on science will tell you just how certain the forecast is 40% chance of rain 75% chance of snow this is because conditions in our atmosphere are constantly changing because it is part of a complex system 100% certainty is not in science's nature in reality being 100% certain is uncommon in life too and even in the year 201100 forecast still won't be infallible and I'll tell you something else science is often looked up to to help inform decisions about the natural world sure information obtained through science should help inform Solutions but it's just one piece of of any puzzle sometimes it's even the biggest piece but it's ultimately up to us to decide how we use science to help point the way this last Point surprises some folks science is a social Endeavor it requires teamwork scrutiny collaboration and communication to be at its best in advanced knowledge granted science has its limits it can't shed light on everything only things that can be observed measured and tested in the natural world some things are beyond the realm of science things that can't be proved or disproved like the meaning of life or the existence of anything Supernatural yep science is just one way of knowing but it's a way of knowing that I'm glad we [Music] have
