Today, I went to Seodaemun Museum. On the third floor, there were a Solar System, a Dinosaur Park and an explanation about the Earth. Also, we saw a 3D movie. The movie was short. I saw many planets, like Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. On the second floor, there were many birds, mammals, insects, fish, amphibians, reptiles and dinosaurs. I saw a T-Rex, a Troodon (?), a Stegosaurus and a Triceratops. There were many animals.

* Hi,

Good job! Don't forget to use 'the' in your sentences, and try not to start your sentences with 'and.' Also, try to use one tense (i.e. present versus past tense). Other than that, great work!
