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. 

Guide your chemistry class through the periodic table so that they are able to identify atomic radii, electronegativity, and ionization energy. Give them three metals to place in water to observe reactivity. Teach them to write electron...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

In this chemistry worksheet, students examine the periodic table and how it is used in the context of interpreting compounds and their structure.

Students explain how the elements are arranged in the periodic table. For this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

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...

Young scholars create videos about an element on the periodic table. In this element instructional activity, students work with partners to create a 1-2 minute video giving interesting information about their element. They include the...

Students investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss relative...

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

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...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

Students investigate how to determine the percent composition of a mineral in an ore. In this mining an ore lesson plan, students use chocolate chips cookies to represent an ore and they remove precious minerals (the chocolate chips)...

Students investigate the structure of the atom and its composition. In this atom structure instructional activity, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles...

In this periodic table worksheet, students answer 10 questions about the periodic table, the elements in the periodic table, the properties of elements and the atomic number, symbol and name of elements in groups of the periodic table.

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...

Students examine the periodic table and how it was developed.  In this chemistry lesson plan students identify common properties and uses of elements within a family. 

Students explore the structure and function of the periodic table of elements. Though memorization drills and games, students working in pairs, identify the elements of the periodic table, their grouping, their properties and their...

Learners review how physical and chemical change while discussing the properties. They diagram the electron dot for the first four elements in the periodic table. Students identify elements and state what they know while investigating...

Students construct a periodic table based on the physical and chemical properties of elements. In this chemistry lesson, students share their work with the class and explain why they classified the elements that way.

Pupils identify the general atomic structure of an element represented on the periodic table. They examine bean and rice patterns that have been created by the teacher and posted around the room and then attempt to match the periodic...

Young scholars 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...

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.

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.
