A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Chemistry classes will appreciate this color-coded, single-page reference sheet for The Standard Model of particle physics. It is divided into two main sections: elementary particles and compound particles, both with their antiparticles....

Students observe a demonstration on how we see space between water molecules.  In this experimental lesson students discover what elements make up the things around them and discuss what they learned. 

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

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 explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.

In this carbon activity, students follow directions and use marshmallows and toothpicks to made carbon dioxide and glucose molecules. Students do this to see how carbon changes as a result of photosynthesis.

Binary compounds are explained with the periodic table, atomic charges, and examples. Viewers are taught to name binary compounds and then are presented with a chart of cations and ions. Finally, they see a few photos of forms of silicon...

In this chemistry instructional 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...

Students observe the periodic table and draw the Lewis Dot Diagram.  In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

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.

Students recognize that the fundamental building block of all organic and inorganic matter is the atom. They construct models of a sugar, fatty acid, amino acid and nucleic acid and describe their roles.

In this atom worksheet, students define the atomic theory, compare an atom and a molecule, determine atomic number and number of protons for elements, and draw Bohr models for given elements. This worksheet has 4 graphic organizer, 8...

In this review of general science worksheet, students classify examples of matter as mixtures or substances, homogeneous or heterogeneous mixtures, or elements or compounds. Students also convert several examples using the standard...

In this oxidation reduction worksheet, students read the notes provided about the different types of chemical reactions. Students identify the reactants and products and answer fill in the blank and short answer questions.

Students examine the structure of molecules, their formula, and percentage composition of each element in the compound. They construct an organic compound with different functional groups using a modeling kit, and draw a 3-D structure...

In this Chemistry 1A learning exercise, learners review, molecular weight, solubility, endothermic reactions, and number of protons, neutrons, and electrons for elements. Students review Lewis Structures and how to predict the amount of...

Fourth graders paricipate in a demonstration about bond strengths and bond types.

In this periodic table I quiz, students select the best answer to the given questions. Students apply their knowledge of the periodic table and the arrangement to correctly answer the questions presented.

Second graders participate in a three part lesson in which they identify and describe forms of moisture in the environment. Part one of the lesson involves the three stages of the water cycle, part two focuses on creating humidity by...

High schoolers interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, high schoolers use the same strategies to identify chemical formulas. They...

In this creating bonds instructional activity, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...
