It measures time -like our ancestors - by using hourglasses provided by radioactivity. In the radioactivity hourglass upper part, that gradually empties, are decaying nuclei. At the bottom part, slowly filling up, are the nuclei resulting from these decays. Radioactive hourglasses are used to date the relics of bygone civilizations, by measuring the amount of Carbon, whose decay rate allows for precise age calculations.
Carbon is a radioactive carbon isotope present in the atmosphere, plants and living bodies. At the end of the lecture ask students to create concept maps to demonstrate how a list of key words are related.
