8th Grade Ms. Santos Science The Carbon Atom Purpose: The purpose of this lesson is for students to learn and see that even though molecules may be made up of the same type of atoms their properties can be very different because of the types of bonds that the atoms make with each other. Students are to view and study the Pure Carbon Molecule page, discuss as a class, and take the 10 question quiz at the bottom. Structure of Matter 3. Each of the more than 100 elements of matter has distinct properties and a distinct atomic structure. All forms of matter are composed of one or more of the elements. As a basis for understanding this concept: a. Students know the structure of the atom and know it is composed of protons, neutrons, and electrons. b. Students know that compounds are formed by combining two or more different elements and that compounds have properties that are different from their constituent elements. c. Students know atoms and molecules form solids by building up repeating patterns, such as the crystal structure of NaCl or long-chain polymers. 6. Principles of chemistry underlie the functioning of biological systems. As a basis for understanding this concept: a. Students know that carbon, because of its ability to combine in many ways with itself and other elements, has a central role in the chemistry of living organisms. Carbon Molecule Assessment 1. 2. 3. 4. 5. 6. 7. 8. List the three types of molecules we looked at. Which molecule is the hardest? Which molecule is the softest? Which molecule do scientists use in delivering medicine? How many electrons does carbon have in its outer shell? How many atoms can carbon bond with? Why do pure carbon molecules have different properties? What is the name given to the fullerene molecule that looks like a soccer ball and was named after architect R.Buckminster Fuller? 9. Where can you find carbon? 10. Why do diamonds have such a high melting point?
