Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

In this periodic table worksheet, learners 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...

In this atoms worksheet, students circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

In this review for chemistry worksheet, learners decide if given statements are true or false. Students relate information learned about introductory knowledge gained in chemistry to accurately answer the given questions.

In this atom worksheet, learners will complete 8 fill in the blank statements based on the different parts of an atom. Then students will explain how the arrangement of electrons in an atom is related to the periodic table.

In this elements worksheet, young scholars determine how electrons fill up the energy levels for the first 18 elements of the periodic table. Students determine if elements gain or lose electrons to form a stable ion. This worksheet has...

Students explore the processes of photosynthesis and respiration. For this photosynthesis and respiration lesson plan, students learn about the role of the chloroplasts in photosynthesis and about the role of mitochondria in respiration...

In this biochemistry activity, students complete a table by filling in the missing information about different elements. Students draw the Bohr diagram and the Lewis dot diagram for several atoms.

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...

What is it worth to you? A hands-on instructional activity asks groups to collect weights of different combinations of coins and calculate weighted averages. They use the analysis to understand the concept of an isotope to finish the...

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...

You'll be surprized at how much engineering, design, and creativity can go into a toothpick and a marshmallow. Learners make toothpick sculptures where they construct three-dimentional models by sticking marshmallows and toothpicks...

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 atomic structure worksheet, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what the...

Students investigate the question: "How does a hot air balloon work?" They build small hot air balloons ans then lauch them. Students discuss how they think a hot air balloon floats. Pupils are introduced to the use of models as a...

Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....

Students define vocabulary related to the parts of the atom.  In this matter instructional activity, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with...

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

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...

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

A part of a study of Australian Aboriginal culture, class members listen to a Dreamtime story about a father who stenciled his handprint on a rock wall.  Class members then make their own hand print art representative of themselves...

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Things are really shaping up! Provide young chemists with polyatomic ion practice using an interesting interactive. Individuals complete puzzles focused on molecular geometry and complex ions.

Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.
