In this chemical equations instructional activity, students learn to balance chemical equations by counting the number of atoms of each element in the products and reactants and making them equal. This instructional activity has 5...

The first of two worksheets methodically prepares chemistry novices for naming polyatomic compounds. It begins by having them acknowledge the number of each atom contained in a molecule. Then learners list the valence electrons for a...

In this chemistry worksheet, 10th graders write the name for each of the 12 chemical element symbols that are shown in the chart.

Eleventh graders study the use of the periodic table to develop a better understanding of the chemical elements.

Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Here is an interesting activity which invites learners to focus on understanding and interpreting the symbols used in writing and communicating information about chemical elements, compounds, and equations. The hope is that this...

Learners discuss matter and atoms using this resource. First, they look at a website describing atoms. Then, they learn about the periodic table and discuss how it is organized. Finally, they create a comic strip to display their...

In this chemistry worksheet, 10th graders write the names for 12 element symbols. They complete a chart by writing the element names next their symbols.

For this chemistry worksheet, 10th graders write the symbols for 12 elements that are named in a table. They complete the chart by writing the names in the blanks next to each element name.

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

High schoolers divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Students examine the effect of hazardous chemicals on humans. They discover how the chemicals are cleaned up and the facilities in their neighborhood. They identify federal and local agencies that oversee environmental hazards

In this alchemy worksheet, students read about how alchemists kept their experiment notes in secret code. Students design their own secret code for the given elements. This worksheet has 2 problems to solve.

Students explain how the elements are arranged in the periodic table. In this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

In this elements worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 25 clues given.

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Biology learners should understand a few chemistry basics. Here is a worksheet that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to life....

A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Tenth graders observe various chemical reactions in the lab. For this chemistry lesson, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.

Students prepare an ad for an element, including properties and uses, in an attention getting format such as that used in the advertising business.

Students, using a Web site about the periodic table of elements, create spreadsheets representing elements and their properties. They also create graphs that compare the physical properties of the elements.
