Students read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.

Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...

Students conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Learners use runaway slave advertisements to discover how the language varies from the 18th to 21st century. Using primary source documents, they research the brutality of slavery and the desire of those in slavery to be free. They...

Fifth graders investigate atoms. For this atom lesson, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

How can one easily classify metals, nonmetals, and metalloids? Pupils answer this question as they experiment with unknown substances and perform tests on conductivity, brittleness, and malleability to determine...

Students research about the chemical processes involved in cave formation. In this chemistry activity, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

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...

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...

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

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

In this chemistry worksheet, students complete 29 fill in the bank questions about atoms based on the movie Exploring Atoms from the website www.brainpop.com .

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

For this compounds worksheet, learners learn the rules for naming compounds, the stock system. Students apply these rules by writing the names or formulas for the 20 given compounds.

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,...

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

In this naming chemical compounds worksheet, students are given 9 lettered statements that they use to match with 10 statements about compounds. Students also review the rules for naming compounds by filling in 25 blanks to complete...

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...

In this chemical bonding worksheet, learners answer 10 questions about ionic bonding, covalent bonding, metallic bonding, Lewis structures, and intermolecular forces.

In this stoichiometry worksheet, students review definitions and equations associated with molarity, density, atomic mass, molarity, and dilutions. This worksheet has 18 word problems.

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

Eighth graders practice balancing chemical equations. In this chemistry instructional activity, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.
