In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

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 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...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

In this atomic structure and periodic table instructional activity, high schoolers complete a table with isotopes, their atomic masses, the number of protons, neutrons and electrons and mass number. They also find the average atomic mass...

Fifth graders relate the elements in the human body to those produced during a supernova. In this space science and chemistry lesson, 5th graders listen to a lecture and view visuals about the big bang. They relate the production of...

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.

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

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...

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

In this main group worksheet, students apply their knowledge of the organization of the periodic table to correctly answer 30 multiple choice questions. Students relate information about the properties of the different groups and their...

In this atomic structure worksheet, students use the periodic table to complete a chart for 11 elements/ions in terms of atomic number, number of protons, neutrons and electrons.

In this matter worksheet, students review the structure of matter including elements, atoms, and the periodic table. This worksheet is a graphic organizer.

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

In this periodic table activity, students review the elements and how they are organized in the periodic table. This activity has 10 fill in the blank, 6 multiple choice, and 5 short answer questions.

In this periodic trends worksheet, students solve ten problems related to elements in the periodic table. Students write electron configurations for atoms and they compare elements and their periodic trends.

For this periodic table and elements worksheet, students review valence electrons, octet rule, oxidation number, and the difference between metals and non-metals on the periodic table. This worksheet has 5 matching, 20 fill in the blank,...

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...

Students explain how elements are arranged in the periodic table. In this chemistry lesson plan, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.
