We learned about dinosaurs and other organisms that used to live in Utah millions and millions of years ago. There are many different types of fossils that show that Utah was humid, tropical, and had lakes. We find shells, trilobite, Allosaurus, and tropical plants in the sedimentary rocks of Utah today. Utah has gone through a lot of change since then!
We then made our own “mud”, and organisms that then fell in the mud and died. We are going to see what happens over “millions” of years as more layers form on top.
Congratulations Samantha on being our bike winner! Thank you to Utah Storm Water for the great presentation on how to keep our water clean.
We’ve been learning about 3 ways fossils are formed: Trace fossils (tracks left behind), mineral replacement (minerals soak into bone or tree, then harden), and preserved organism (organism actually preserved). It’s been so wonderful to learn more about this myself, and then see how fast these 4th graders soak up the information. Keep it up!
