An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

In this chemistry review worksheet, students classify and name compounds, calculate atomic mass, draw Lewis Dot Diagrams, and determine number of protons for atoms. This worksheet has 37 fill in the blank, 38 matching, and 3 short answer...

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...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

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...

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...

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...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

Students research elements on interactive Internet periodic tables, take notes using Inspiration software, and write descriptive paragraphs with graphics. They create presentations.

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....

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

In this chemistry worksheet, young scholars 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. In this chemistry instructional activity, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an...

For this early atomic theory worksheet, students answer 4 questions about the Law of Definite Proportions, the Law of Conservation of Mass and Dalton's Laws. Students are given 5 statements to determine if each true statement supports or...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

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...

In this isotopes worksheet, students find the average atomic mass given the masses of two isotopes. They also calculate the atomic mass of elements given the percentages of each isotope.

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...

Here is a six-page exploration that will spark interest in the periodic table of elements. After reading a diagram-supported explanation of the periodic table's organization, pupils answer questions to familiarize themselves with it. To...

For this periodic table worksheet, students complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...
