Students work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a report as...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

In this matter worksheet, students review the structure of matter including elements, atoms, and the periodic table. This worksheet is a graphic organizer.

Middle schoolers classify materials. In this chemistry lesson, students examine the properties of solids, liquids, and gases. Middle schoolers discover the elements, compounds, and chemical symbols.

Giving a clear review of the basic properties of the metals in groups one and two on the periodic table, this slide show would be useful for early learners of chemistry. Your class will learn about the trends down the groups, such...

Learners explore naturally magnetic elements. In this magnets lesson, students examine the periodic table of elements. Learners discover the parts of an atom and determine which three elements are magnetic.

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

For this elements worksheet, students complete a graphic organizer comparing lithium, sodium, and potassium observations. Then, they determine how these elements react with water. Students complete three fill-in-the-blank questions.

High schoolers are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

In this chemistry learning exercise, students calculate specific changes that take place with different chemical reactions. Students indicate whether the reactions are endothermic or exothermic and spontaneous or nonspontaneous.

In this elements learning exercise, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This learning exercise has 20 short answer...
