A instructional activity 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...

For 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.

Students 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 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...

In this periodic table worksheet, young scholars complete a crossword puzzle given 19 clues about elements, symbols, properties of elements, atomic number and atomic masses of elements.

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...

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 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 investigate the structure of the atom and its composition. In this atom structure lesson, 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...

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 create videos about an element on the periodic table. In this element lesson, students work with partners to create a 1-2 minute video giving interesting information about their element. They include the name, symbol, atomic...

For this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each...

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.

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 moles worksheet, students 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.

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...

Learners examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

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

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 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...

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.

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.

High schoolers 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 instructional activity, they discover...
