Quiz: elemental pursuit
How much do your students know about the properties of the chemical elements and how they are used? Find out with this elements quiz, based on articles in Science in School.
As every science teacher knows, the periodic table is a time-tested directory of elements that arranges all known elements according to their atomic number. Very neatly, the periodic table also reveals links and trends between the elements in terms of their physical and chemical properties.
Over the years, Science in School has published a variety of articles that feature many of the elements and how they are used in the sciences, technology and industry. So, to mark the 150th anniversary of the periodic table, we bring you this quiz, which teachers can use to spark discussions about some of the chemical elements, their uses and importance. Students will be able to complete the quiz using only Science in School articles, which are all free to read on the websitew1. The quiz is also available as a downloadable worksheet from the additional materials section.
We hope the quiz will encourage your students to appreciate the huge diversity of the chemical elements and their many fascinating applications. Teachers interested in receiving answers for this quiz – complete with the Science in School source article(s) for each answer – are invited to email us at editor@scienceinschool.org.
