In this elements worksheet, students read how the elements are organized in periods and groups in the periodic table. Students use the periodic table to find the valence electrons and calculate molecular mass. This worksheet has 20 fill...

Students will review a semesters worth of material on this final chemistry review. Information ranges from naming isotopes to pH and molarity.

In this chemistry review instructional activity, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

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...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

The VSEPR Model of molecular structure is exhibited through this series of slides. The step-by-step process is listed, and then examples are provided. The graphics give a visual display of the spatial relationship between the atoms of...

In "Nuclear Arthmetic," first-time physical scientists examine atomic structure and the periodic table of elements. The are given the formula, "N = A-Z," in which N is the number of neutrons, A is the atomic mass, and Z is the atomic...

In this percent composition worksheet, students find the percent of each type of atom in a compound, they find the total mass of a sample and they determine the mass of particular atoms in a compound.

In this alkanes instructional activity, students complete a table with the chemical formula, the structural formula and the condensed formula of various alkanes given different numbers of carbon atoms. They answer three questions about...

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...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

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...

In this molecules worksheet, students combine different food colorings that represent atoms to make different molecules. Students read 7 directions and answer 2 questions.

Students create an atomic model using a computer program. In this technology instructional activity, students identify the difference between radius and diameter. They create circular patterns and spheres based on certain specifications.

For this atoms worksheet, students determine an atoms based on its protons, and neutrons. Students determine the electron levels for the oxygen atom. This worksheet has 1 multiple choice, 4 fill in the blank, and 13 short answer questions.

In this atoms worksheet, students review the parts of an atom, Bohr diagram, atomic number, mass number, and covalent bonds. This worksheet has 5 drawings and 26 fill in the blank questions.

In this chemical equations worksheet, students review the rules in balancing equations and then balance 11 chemical reactions.

In this moles worksheet, students determine the mole ratio in given compounds and calculate the number of moles of specific elements in chemical compounds. This worksheet has 19 problems to solve.

In this moles worksheet, students complete 93 word problems in they calculate the moles, volume, or mass of different molecules.

In this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

Where does an electron reside? Chemistry scholars determine an electron's "address," that is, what orbital it can be found in. This resource is both instructional and practical,  providing a thorough explanation of energy levels and...

In this chemistry worksheet, students write how many chiral C's are in each of the compounds listed. Then they draw the Fischer projections for all stereo isomers in 5 and in 6. Students also match the correct Fischer projection to each...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...
