Earth science has 5 parts, and if you listen to this song they’ll be stuck in your heart. Astronomy, the study of space, the people down at NASA really know their place. Meteorology, the study of weather, if you study the clouds they’ll be as light as a feather. Geology, the study of stuff in the Earth, from the magma below to the worms in the dirt. Oceanography, the study of salt water, it’s good in your dinner but drinking’s a bother. Environmental science, the study of living
things. The study of where they live and how they grow, how we affect them and the places they go. Now we go to the Earths systems, and there are four, so keep on listening you’ll learn even more. Geosphere, it’s the surface to the center, there are only 3 parts so you better remember. Atmosphere, the gases that surround the planet, if we break the ozone layer we can all can it. Hydrosphere, all the water on the Earth, from the water in the oceans to the water in the dirt. Biosphere, the living things again, the climate that they live
in from the jungles to their dens. Lastly, we have technology, its human advancement, like cars saving energy. Now that parts over, let’s move on. Its Method in a Minute, come on! Collect info, observe, ask questions and review. Then you form the hypothesis which should give you a clue. You conduct the experiment and record the information, then compare the results and draw a conclusion. Then you share the results and make sure they’re true,
and share them with scientists all around you. Measurement, it seems simple enough but when you use SI units it starts to get tough. Length, meters Temperature, Kelvin Weight is kilogram and mass is Newton. To find the volume just cube the meter. To find the density it’s mass over volume Now we switch to graphs and there are 3 types. The line, circle, bar are all hyped. A scientific model is an idea picture, like modeling parts
of an unknown creature. Scientific theory is an explanation that is always based on many observations. Lastly there’s the scientific law, it’s like a rule of nature that controls us all. I hope you now know what we’re talking about. This was Sam and Victor and were finally out.
