Working in groups (3-4 students), go to the above internet site. Once you are at the site, each student should take turns trying to get the planet in orbit around the sun. This will require you to manipulate the speed and angle at which the Earth moves towards the Sun. Ultimately, you are trying to get the Earth to move around the Sun so that it takes 365 days for one complete revolution. Be sure to notice what happens when the Earth does not move towards the Sun at the correct angle or speed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
