Beginning chemists examine a collection of elements and compounds as they are introduced to the periodic table. The lesson plan is not cohesive and does not provide detailed instructions on how to teach it. However, it does includes a...

Pupils practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Students examine the atomic structure of elements.  For this chemistry lesson students organize elements of the periodic table according to their atomic mass, and compare their order within the periodic table. 

In this making molecules worksheet, students complete a table of elements with their symbol, atomic number, atomic mass, number of protons, number of electrons, period and group. Students then make models using pipe cleaners and beads of...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Students use reference skills to locate information about the periodic table. They identify elements by name, atomic number, atomic mass, symbol and properties. Students use mathematical processes to find the number of protons,electrons...

High schoolers explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence...

Students are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the characteristics...

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...

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...

Young scholars collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They...

Students are introduced to the periodic table. They find the common trends among the electron configurations and the names of certain groups of the table. Students explore the atomic mass, atomic number, mass number, mass and charge...

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...

Students demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

Students review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

High schoolers are introduced to the mole concept using a discovery-based method. Lesson includes activities with candy that allow students to discover the rules for mole-item, item-mole, mole-mass, and mass-mole conversions.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

Students examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Pupils explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

Young scholars diagram nuclear power plant, describe process for generating electrical power, discuss nuclear disasters in the 20th century, and draw conclusion about value of nuclear power for the future.

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...
