One of my favorite projects was the one about Makemake. The project described what Makemake was made out of, as well as how it was discovered. It also described what a dwarf planet is, and why Makemake is classified as one. Even though not much is known about Makemake and scientists are not sure if what they know is true or not, it was still a really good project that summarized what could be true.
The Birth of the Solar System was also a good project. This project talked about how solar system's in general are created, and then specific details about when our solar system was created and from what. The project also talked about what will happen to our solar system in the future, including the inevitable process of our sun becoming a Red Giant and eventually turning into a nebula or blackhole.
My third favorite project was the one about Titan. This project described the basic characteristics of Titan, such as facts about the atmosphere, surface, and location. The project also talked about who discovered the moon, and whether or not there could be life on Titan, which was the most interesting part of the project.
