What on Earth? Where on Earth?

Life Science
Today, we discussed the possible origins of single-celled organisms. Urey and Miller conducted an important experiment which replicated the conditions of the early Earth. Their results yielded small chemical components which can combine to form proteins. Other similar experiments produced carbohydrates and nucleic acids (DNA). We covered the parts of prokaryotic cells as well as how eukaryotic cells may have developed. Homework is for students to complete their poster and paper for "The Cell is like... " project. All students will be presenting their projects to the class.
