The text describes scientific inquiry through guided activities: observing the night sky, drawing star patterns, recording dates and times, identifying moving objects, and documenting findings. It also surveys topics such as the eight planets, their sizes and orbits, day length on Mars, the solar system’s scale, and whether more planets exist.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/literature/","Literature",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/why-isnt-pluto-a-planet-a-book-about-planets/437330/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/why-isnt-pluto-a-planet-a-book-about-planets/437330.png","ImageObject",300,407,{"name":42,"@type":43},"Logic","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-29",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What makes something a planet?","Question",{"text":63,"@type":64},"Planets are round and do not have other objects of similar size floating nearby.
