Every region has a renewable resource that can be used to make hydrogen. But, what is hydrogen and why can it be used as an energy source? Find out with a presentation that answers these questions and then discusses where hydrogen is...

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...

Learners investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality studies.

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...

Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity...

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...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

In this compounds worksheet, students describe why metals and nonmetals form ionic compounds and why the formation of ionic compounds are exothermic. This worksheet has 5 short answer questions.

In this compounds worksheet, students compare the differences between compounds and mixtures. This worksheet has 3 short answer questions.

Students practice naming and writing formulas for simple chemicals. After a review of vocabulary, they create ion flash cards and discuss the rules for writing chemical compounds. They practice naming and writing the formulas based on...

For this elements worksheet, students complete a graphic organizer by comparing the elements' melting point, boiling point, density, and electronic configuration. Students determine the characteristics of Group 7 elements. This worksheet...

Students investigate how information about the atom has been determined. In this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

In this inorganic compounds worksheet, students complete 2 charts by writing the names or chemical formulas of given ionic and covalent compounds.

Learners conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

In this organic and biochemical compounds worksheet, students identify compounds as alkanes, alkenes or alcohols. They compare and contrast the similarities of each. This one-page worksheet contains 6 problems.

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

In this word search worksheet, students locate 20 words related to science. The word list includes volume, mixture, and solute.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students examine the carbon cycle while identifying its sources, sinks, and release agents. Using magazines and newspapers, groups of students design collages illustrating the carbon cycle. Finally, they write responses to several...

In this chemical bonding worksheet, students review the different types of bonds and calculate the number of valence electrons in molecules. This worksheet has 11 matching and 15 multiple choice questions.

Students investigate the effects of air pollution. In this environmental lesson, students discuss the causes of air pollution and identify how transportation has an effect on the air quality. Students identify other alternatives to driving.

In this chemical bonding worksheet, high schoolers review the three types of compounds: ionic, covalent, and polyatomic. Students practice drawing the covalent bonds of given compounds. This worksheet has 5 drawings and 13 fill in the...

In this chemical bonding learning exercise, students review the three types of bonds including ionic, covalent and polyatomic compounds. They identify 8 compounds as ionic, covalent or polyatomic and they make 4 ionic compounds and they...

In this formula mass activity, students read about molecular substances and their formula masses. They find the formula masses for six compounds using the atomic masses of its elements.
