Carbon dating elementary computers and back dating
Each carbon atom can form four single covalent bonds.These bonds allow carbon to form long chain-shaped molecules, called polymers, such as plastics. A special, man-made, tube-shaped allotrope of carbon is the carbon nanotube. A radioactive isotope of carbon, carbon-14, can be used to figure out how old some objects are or when something died.
Students use M&Ms to demonstrate the idea of radioactive decay. Parent isotopes are represented by the M side up (radioactive).
Students should have some prior knowledge of rocks and how they are dated. Materials Needed: -100 M&Ms (per group) -Notebook -Piece of Paper -Plastic Container with a Lid Lesson should be introduced by reviewing the 2 broad ways scientists age rocks (relative dating and radioactive dating).
