3D Online Model of the Solar System For this lab, you will learn about some of the major objects in the solar system by interacting with an online 3D model. Go to https://www.solarsystemscope.com and explore this 3D model. You can use the tools in the bottom right corner to navigate around. Click on each of the objects in the solar system in order to access information about each object. You can either search around the solar system to find them yourself, or you can click on the name of each object listed in the box on the left side of the website. Answer the questions below after listening to or reading the content provided on the website about each object. I recommend that you print the lab, fill in your answers, and then use those to input your answers into our online class site so that you can then get credit for the laboratory exercise. Sun 1.
