An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....

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...

In this chemistry worksheet, students find the formula weight for each of the substances listed on the sheet. Then they find the percentage composition as indicated.

In this chemistry worksheet, students identify how much aluminum and hydrochloric acid is needed to produced a certain amount of hydrogen gas. Then they identify how many grams of oxygen are used.

In this chemistry lab worksheet, students perform an experiment using fluorine, chlorine, bromine, and iodine and determine their relative atomic weights.

In this Grahams Law learning exercise, students determine which gas will escape faster when equal amounts of helium and argon are placed in a porous container and allowed to escape. Then they determine what the molecular weight of a gas...

In this chemistry worksheet, students identify and locate various vocabulary terms related to metals found in the periodic table. There are 54 chemistry terms located in the word search.

For this chemistry worksheet, students identify and locate various vocabulary terms relating to the elements found in the periodic table. There are 116 chemistry terms located in the word search.

In this chemistry activity, students complete the chart for each of the given elements by naming the number of protons, electrons, Valence electrons, and the electrons used to fill the outer shell. Then they complete each covalent bond...

For this chemistry worksheet, students write the word equations listed as chemical equations and balance each one. There are eight of these to solve on the sheet.

In this chemistry worksheet, students name each of the listed compounds on the sheet. Then they compare each of the compounds to those of the periodic table.

In this chemistry learning exercise, students identify and write how many significant figures they would use for each problem. Then they round the answers to the appropriate number of significant figures. Finally, students calculate the...

In this chemistry instructional activity, students balance the listed equations by changing the coefficients. They identify and explain why iron bromide can react with water to produce iron oxide and hydrogen bromide.

In this chemistry activity, students balance the list of equations given using their knowledge of the Periodic table. There are 27 equations to solve on the sheet.

In this chemistry worksheet, students identify ways to memorize the elements and symbols of the periodic table for chemistry. They identify phrases that use each element in a unique way.

Learners use test kits to measure the level of chlorine, iron, sulfide, and dissolved oxygen in tap (drinking) water and stream water. They post and evaluate the results of these water quality tests.

Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.

Second graders examine the life cycle by observing tadpoles. After reading the book, Tadpole Diary, they draw the stages of tadpole development and write sentences about what they think is happening.

Students learn what happens when bleach comes in contact with various cloth fibers, chemical colors, nature and synthetics.
