In this task, you will design a scale model of the solar system. A simple scale model would depict the Sun and eight planets to scale. Research online for resources that provide information on creating a model that scales up to the proper dimensions of the solar system. Use this site to calculate a scale for the various bodies in the solar system by specifying a fixed size for the Sun. (Note: distances between planets in the solar system are extremely large, so it is recommended to perform this task in an open park for best results.) Record your findings and provide a detailed explaination of how you visualized your scale model. Link to the image is exploratorium. edu/ronh/solar_system/

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
