Students create models of ionic and covalent electronic bonds to demonstrate their understanding of these chemistry concepts. They explain how both ionic bonds and covalent bonds work so that younger students can understand.

For this chemistry calculations review worksheet, students solve 33 review problems about titrations, precipitates, pressure and volume of gases, combustion reactions, heat of combustion, molar concentrations and molecular formulas.

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

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

In this balancing equations instructional activity, students determine the type of reaction and write the balanced equation. Students read the word description and write the symbol of each element using the periodic table.

Students identify elements on the periodic table and how to read it. They create their own chart for alkali metals and alkaline earth metals. They are evaluated based on a rubric.

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Learners write electron configurations and identify groups.  In this investigative lesson students use valence electrons to draw electron dot structures. 

Students understand the difference between four different types of chemical reactions: composition, synthesis, single replacement, and double replacement and identify the type of reaction and predict the products of these types of...

For this making atoms science worksheet, students read about the atomic number of protons, finding the number of neurons, and how electrons function before they complete the atom board graphic organizer and respond to 4 short answer...

In this chemical equations worksheet, students fill in the blank with information about how to form chemical equations using the "ide" rule and the "ate" rule.

Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Students explore the definition of matter.  In exploring matter lesson students get into groups and navigate the Internet to answer questions. 

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

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

In this chemistry activity, 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...

Students discover the best practical shielding material when dealing with radioactive substances. They draw conclusions based on availability of materials, price, and best shielding properties.

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

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 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.

In this atoms worksheet, students 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.

Eighth graders define a planet by the orbit around the sun, have a large enough gravitational force to hold a sphere shape and needs to clear the neighboorhood of it own orbital zone. They describe comets, meteoroids, meteor, meteorites...
