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...

For this National Olympiad exam worksheet, chemistry apprentices answer sixty multiple choice questions including general chemistry topics such as atomic structure, gases, problem solving, writing and balancing equations and solutions....

Eighth graders investigate objects for a specific element from the Periodic Table.  In this elemental photography lesson, 8th graders observe for and object and photograph it. Students use photographs to prepare a multimedia...

Fourth graders examine matter and the periodic table of elements. In this matter lesson plan, 4th graders discuss atoms and their composition. Students explore the periodic table of elements and use it to spell words out of the elements.

Students experiment with transition metals.  In this transition metals lesson plan students find the common properties of transition metals and conduct an experiment using one of them.  Students then answer questions regarding...

In this elements learning exercise, learners complete two graphic organizers by comparing the element symbol and melting point for given elements. Then students plot a graph of their atomic radius against proton number.

Eighth graders explore information about the periodic table of elements. Using the Internet, 8th graders choose one element to research. They complete an "Adopt and Element" information sheet. Using Microsoft Word, students create an...

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...

In this chemistry worksheet, students use an interactive website to study the names and symbols of elements. They give the names and symbols of 69 common elements.

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 chemistry worksheet, learners answer 24 questions related to properties of halogens. They fill in the table with the correct answers and participate in teacher demo.

Using the periodic table of elements, young chemists fill in a chart of isotopes to show the atomic number, mass, charge, number of protons, number of neutrons, and number of electrons. The chart is followed by 11 questions that...

What are alloys, and why do we use them? Through a series of interactive puzzles, scholars examine the components and uses of several common alloys. The accompanying teacher's resources provide support in using the lesson, printable...

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

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.

In this Lewis structures worksheet, students identify and describe what Lewis structures or dot diagrams are and how they illustrate the valence electrons in an outer shell. Then they use a periodic table to determine the numbers of...

For this conversion worksheet, students make the following conversions, showing each step. Students use the periodic table and express all molar masses to 1 decimal place.

In this chemistry worksheet, students find the symbols for 12 elements on the periodic table. They write the symbols on the lines next to the names of the elements to complete a chart.

Fourth graders, in groups, compile information on groups of elements. They study Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gases.

In this chemical reactions worksheet, students name the reactants and products, balance the equation, calculate the molecular weight of the reactants and products, and classify each reaction type. Students fill in a table of solubility...

In this elements activity, students compare and contrast the characteristics of metals and non-metals. Students practice drawing Lewis dot diagrams and writing ion notation. This activity has 9 word problems, 8 matching questions, and 5...

Young scholars explore an interactive program about the periodic table. They use the Kalzium software to dynamically explore the relationships between elements, the periodic table and properties of the elements.

In this element activity, students choose an element from the Periodic Table. Students pretend they are the element and answer the questions.
