Learners examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

For this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

In this science worksheet, students use a periodic table to complete the first four rows of a chart. Students use the Internet or research books to complete the last column.

Students identify the different periodic trends. For this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Students explain how elements are arranged in the periodic table. In this chemistry lesson plan, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.   

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
