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.

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

Students investigate the Periodic Table of Elements. In this chemistry lesson, students use a post of the Periodic Table to identify the mass number, atomic number, and atomic symbol. Students create a Podcast to "advertise" a specific...

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...

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

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...

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

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.

In this moles worksheet, learners practice calculating the number of moles based on grams of a compound. Students use the rate of reaction equation to determine the rates of specific reactions. This worksheet has 10 problems to solve.

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

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.

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...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Young scholars 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.

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...

In this stoichiometry worksheet, students practice calculating moles, molarity, and the concentration of a solution in molarity. This worksheet has 12 multiple choice questions and 3 problems to solve.

Learners discuss matter and atoms using this resource. First, they look at a website describing atoms. Then, they learn about the periodic table and discuss how it is organized. Finally, they create a comic strip to display their...

Young scholars explain how the elements are arranged in the periodic table. In this chemistry instructional activity, students determine the subatomic particles for certain elements. They research the physical and chemical properties of...

Hopefully by the time high schoolers are enrolled in your chemistry class, they are skilled with unit conversion. It does not hurt, however, to take an hour early in the school year to review this vital skill. This plan simply provides a...

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...

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...

Students 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.
