Students simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

Students are introduced to the characteristics of crystals and what keeps them together. Using the Periodic Table, they examine the various elements and develop a model of an atom. In groups, they place sugar and salt in petri dishes...

Students participate in an angular solution of hydrogen activity. Using this activity, students also illustrate eigenvalue problems applied in mathematics. They explore Schrodinger's equation and particle wave duality.

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

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.

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

In this minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

Students create models of structural isomers, geometric isomers, and polymers.  In this chemistry instructional activity, students are given definitions and molecular model kits to create a variety of different isomers and polymers.

Learners examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

In this review for chemistry worksheet, students decide if given statements are true or false. Students relate information learned about introductory knowledge gained in chemistry to accurately answer the given questions.

In this molecular formula worksheet students fill in a table describing elements and chemical formulas. They identify, elements by type and how they bond. The student analyze molecular formulas to identify the number of atoms and if the...

In this biochemistry worksheet, students complete a table by filling in the missing information about different elements. Students draw the Bohr diagram and the Lewis dot diagram for several atoms.

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 study hydrocarbon gases and chemical equations. In this hydrocarbon gases lesson, students work in groups complete a molecular formula worksheet and review alkane prefixes. Students complete molecular models, balance chemical...

Students demonstrate their understanding of a chemical process.  In this exploratory lesson students create a clay animation that shows how a specific type of chemical bond. 

For this honor chemistry I worksheet, pupils use all available resources to answer each question given. Students apply their knowledge of light, quantum theory of light, Bohr's model, photoelectric theory.

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

Students brainstorm what matter is and how they define it. They construct a water molecule with marshmallows and toothpicks. In addition, they watch videos to explore the use the idea of nanoscience to investigate the properties of...

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

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...

Students use M&Ms to simulate radioactive decay of elements.

Students recognize the benefits of ethanol and study photosynthesis.  In this ethanol lesson students complete an experiment that shows the procedure that starch can be hydrolyzed by salivary amylase.
