In this creating atoms worksheet, students follow directions by creating atoms out of cotton balls, beads, and pipe cleaners. Students then answer 2 questions.

In this chemistry worksheet, students identify and write how many significant figures they would use for each problem. Then they round the answers to the appropriate number of significant figures. Finally, students calculate the mass of...

Pupils discuss metalloids, their use as semiconductors, and their impact on the computer industry. They work in groups to create a visual timeline showing the evolution of the computer.

Students explain the mole concept and use this concept to prepare chemical solutions of particular molarities.

For this AP Chemistry worksheet, students apply concepts of electron configuration to accurately answer the questions provided. Students also draw Lewis structures of the given elements. Students estimate the enthalpy of formation as...

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

In this atoms worksheet, learners explore the different types of bonds, name compounds, and determine charges of molecules. This worksheet has 8 true or false, 9 fill in the blank, and 5 short answer questions.

How can one easily classify metals, nonmetals, and metalloids? Pupils answer this question as they experiment with unknown substances and perform tests on conductivity, brittleness, and malleability to determine...

Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...

Students create a polymer to demonstrate its properties and develop an awareness of the wide variety of uses for polymers.

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Students conduct a flame test on different substances. For this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.

Fifth graders investigate atoms. In this atom instructional activity, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Young scholars investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Students tour Chandra's top galactic X-ray images. In this Chandra X-Ray Observatory lesson, students play games and complete puzzles based on the Chandra Mission and X-Ray Astronomy. Students listen to pod casts, question an...

Students research about the chemical processes involved in cave formation. For this chemistry lesson, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Eighth graders practice balancing chemical equations. In this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

In this naming chemical compounds worksheet, high schoolers are given 9 lettered statements that they use to match with 10 statements about compounds. Students also review the rules for naming compounds by filling in 25 blanks to...

In this quantities in chemistry worksheet, high schoolers solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and percent...

In this chemical bonding activity, students answer 10 questions about ionic bonding, covalent bonding, metallic bonding, Lewis structures, and intermolecular forces.

In this stoichiometry worksheet, students review definitions and equations associated with molarity, density, atomic mass, molarity, and dilutions. This worksheet has 18 word problems.
