A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

In this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

Scholars learn about the carbon cycle, play a carbon cycle game, and then write a story based on their role as a carbon atom during the game. After the writings, pupils analyze the carbon cycle by leading a class discussion on the material.

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

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...

Viewing this slide show prepares your chemistry scholars for chemical nomenclature. Specifically, binary hydrogen compounds and ternary compounds formed from oxyacids are dealt with. One highlight is a useful graphic organizer for naming...

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

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

In this kinetic molecular theory worksheet, young scholars summarize the points of the kinetic molecular theory, they answer questions about pressure, and draw diagrams to show how suction cups, drinking straws and barometers work.

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...

In this percent composition worksheet, students find the percentages of atoms in compounds and they determine empirical formulas given the percent of each atom in a compound.

In this percent composition activity, high schoolers 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.

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

Using chlorine as the model to demonstrate the structures and representations, this PowerPoint clearly labels and details the main atomic structures and reasons for bonding. The electrons in the outer shell are diagramed and then the...

What killed the dinosaurs and how do scientists know? Your high schoolers can examine these fascinating questions with a geochemical lens using the engaging 33-minute video, the accompanying data interpretation, and some thoughtful...

Scholars explore U.S. Foreign Policy and Cold War ideologies adopted after WWII. They conduct Internet research on a topic or issue related to the Cold War Era, watch two films, and compose a time line and a multimedia presentation to...

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...

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

In this periodic table worksheet, students write the chemical symbols for the given elements, compare atomic number and mass number, and describe the importance of valence electrons in the organization of the periodic table. This...

In this water learning exercise, students compare and contrast elements and compounds. Students define chemical symbols, chemical formulas, and chemical properties. This learning exercise has 19 short answer questions.

For this resources worksheet, students compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This worksheet has 56 short answer questions.
