As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

For this chemistry worksheet, young scholars write the structures for the compounds listed at the top of the sheet. Then they name the compounds whose structures are illustrated. Students also write the mechanism for the reaction of...

For this chemistry worksheet, young scholars determine which compound is the most acidic in each multiple choice question. Then they determine what the major product would be in each of the reactions stated on the sheet.

Determine if sentences are simple, compound, or complex in this grammar worksheet. Young grammarians write the sentence type on the line under each of eleven sentences.

In this chemical compounds worksheet, students draw and correct Lewis structure for the given compounds or ions. Students draw the resonance structure if applicable. This worksheet has 8 problems to solve.

Learners use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

Students visualize and manipulate sentences as building blocks, and, given a key, use Legos™ to demonstrate how to construct sentences of variety (simple, compound, complex, and compound-complex).

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.

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

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

In this matter worksheet, students complete a table in which they compare elements, compounds, and mixtures. Once table is finished, they answer 6 fill in the blank questions.

In this matter worksheet, students review the structure of matter including elements, atoms, and the periodic table. This worksheet is a graphic organizer.

An inquiry lab where students try to separate as much as the pure substance they can in a set time period. This lab helps students understand that physical means can be used to take apart a mixture.
