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,...

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.

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 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...

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...

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. 

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...

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 plan, they discover the...

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...

Students verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic theory,...

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 periodic table worksheet, students determine why the periodic table is organized the way it is and compare and contrast the characteristics of the different grouping of elements. This worksheet has 22 short answer and 36 fill in...

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.

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 investigate the properties of elements and periodicity. In this periodicity lesson plan, students observe a bag of 'elements' which are different fruits and classify them in groups and periods, show the periodic relationships...

Learners study the particles of which atoms are made. They define the electron, proton, and neutron and their attributes.

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...

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...

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.

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

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.
