Learners are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

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 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...

Student teams use a digital camcorder and iMovie to create a commercial about an element. They also use the Internet and their textbook to gather the following information about their element: the name, the symbol, the atomic number, the...

Learners examine the atomic structure of elements.  In this chemistry activity 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...

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 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 Periodic Table of Elements. In this chemistry activity, 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 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...

Students research the use of the atomic bomb in WWII, analyze the human costs of dropping the bomb and identify the pros and cons. They develop a PowerPoint presentation on the effects of an atomic bomb dropped on their hometown.

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...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

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...

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.

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.

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 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 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...

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 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 to...
