Periodic Table of Elements — Interactive Lesson, Poster & Worksheet (Ages 11–14)

Can your students decode the periodic table? This 41-slide interactive lesson teaches the periodic table, with a classroom poster and a worksheet included.

Mastering the Periodic Table in KS3 Science

Students learn about the periodic table and its history, including Dmitri Mendeleev, identify elements using their symbols, explain why the table has its current structure and evaluate different ways of arranging elements. They learn that elements are arranged in order of increasing atomic number, that rows are periods and columns are groups, and that elements in the same group are similar. They then explore families such as the alkali metals, transition metals, halogens and noble gases.
