Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Vocabulary that is essential to this topic is introduced and defined at the start of this slide show. The following slides help students understand proteins and their use and involvement in everyday substances. Great diagrams help your...

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The lesson is simplistic, but the Internet resources provided...

Pupils explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

In this intermolecular forces worksheet, students read about the two types of forces: dispersion forces and dipole-dipole forces. Students then complete 2 problems based on what they read.

In this solvent worksheet, students explore why water is considered a universal solvent. Students explore what can change dissolving rates. This worksheet has 8 matching, 3 short answer, 11 fill in the blank, and 4 problems to solve.

In this Chemistry 1A worksheet, students review, molecular weight, solubility, endothermic reactions, and number of protons, neutrons, and electrons for elements. Students review Lewis Structures and how to predict the amount of product...

Designed to prepare seventh graders for the Georgia Criterion-Referenced Competency Tests, this activity can be used for any type of standardized test, as well as reinforcement of reading comprehension skills. Eleven questions about two...

Students predict the shape of molecules using VSEPR theory. In this chemistry instructional activity, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

For this literature response worksheet, students draw a picture of the Northern Lights. This worksheet is in response to the events in the Magic Tree House book, Who Turned the Lights On?

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  For this water lesson students work in groups and complete several activities. 

In this molecular geometry and hybridization worksheet, students identify bond angles, Lewis structures, hybridization, polarity and valance electrons in given molecules. They also label a drawn compound with hybridization and bond angles.

In this intermolecular forces instructional activity, students answer 4 questions about the forces between atoms within molecules and compounds. Students rank the boiling points of compounds based on their intermolecular forces and they...

In this solubility and intermolecular force worksheet, students are given 26 clues about forces between molecules such as hydrogen bonds and London forces and about solubility of solutions.

For this covalent bonding worksheet, students answer questions about types of bonds, electronegativity, valence electrons, and Lewis dot structures. They answer specific questions about covalent bonds in molecules and explain the...

Students explain how melting glaciers affect global warming. In this earth science instructional activity, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...
