Learners read the periodic table and apply their knowledge of the construction of atoms. They demonstrate reading the electron configuration of an element on the periodic file.

Students explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

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.

Students examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Students investigate the length of various objects. For this measurement lesson, students convert one metric unit to another. They explain the importance of a uniform system of measurement.

In this science worksheet, students use the key code on the right to unscramble each of the scientists. They also match each of the scientists found to their correct description.

High schoolers demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.

Students review atomic numbers, positive and negative charges, and the periodic table. They examine the relationships among protons and electrons, location of various elements, electron energy levels, and oxidation numbers.

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 discuss the difference between atoms and elements. They analyze how compounds are formed. Students discuss the difference between covalent bonds, hydrogen bonds, and ionic bonds. They review bonding with diagrams, "Atoms or...

In this chemistry activity, learners locate and identify various vocabulary terms related to chemistry. There are nine words/phrases located in the puzzle to find.

Students identify the type of bonding between two atoms of elements given their electronegativity values. They study the trend of electronegativity across the periodic table in small groups.

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...

For this biochemistry worksheet, learners 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.

In this oxyanions worksheet, learners identify the common polyatomic ions. They write formulas and name polyatomic ions based on IUPAC rules.

Young scholars use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.

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

Learners 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.
