In this periodic table worksheet, learners will label the atomic number, atomic mass, element name, and element symbol for oxygen. Then students will determine the characteristics of the different groups of elements on the periodic table...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

For this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

In this atom worksheet, students complete a graphic organizer for the structure of the atom. They include the definition of the mass number, the atomic mass, the atomic number, the protons, neutron and electrons.

In this periodic table worksheet, students use the periodic table to complete the chart with the given elements. Students fill in the atomic number, atomic mass number, protons, neutrons, and electrons.

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Beginning Boyles and curious Curies can safely experiment with the virtual mixing of elements using this entertaining application. 

In this chemistry instructional activity, students complete an adopt an element information sheet. Then they create an advertisement for their element including the information listed. Students also write its important uses, interesting...

In this nuclear decay learning exercise, high schoolers read about alpha and beta decay and the isotopes formed by the reactions. Students solve nine problems including writing the equations for the decay of radioactive isotopes,...

A lesson about the Manhattan Project will explode young physicists' understanding of the racial attitudes in the United States during and after World war II. Groups select an African American scientist or technician that worked on the...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...
