The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing.  It is important to consider what the experts say, but to also evaluate their statements.  We will start with the scientific method.  I want you to outline the scientific method from what you have been taught in previous classes.  You can list steps, parts, process, short descriptions, whatever.  If not taught in previous classes, then you will make your best guess about it.

The life cycle of a plastic bottle After reading the text below, answer the following questions. Make sure to put it in your own words. This is the story of three plastic bottles, empty and discarded. Their journeys are about to diverge with outcomes that impact nothing less than the fate of the planet. But they weren't always this way. To understand where these bottles end up, we must first explore their origins. The heroes of our story were conceived in this oil refinery. The plastic in their bodies was formed by chemically bonding oil and gas molecules together to make monomers. In turn, these monomers were bonded into long polymer chains to make plastic in the form of millions of pellets. Those were melted at manufacturing plants and reformed in molds to create the resilient material that makes up the triplets' bodies. Machines filled the bottles with sweet bubbly liquid and they were then wrapped, shipped, bought, opened, consumed and unceremoniously discarded. And now here they…
