Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...

For this chemical compounds worksheet, young scholars review the different types of bonding, define the octet rule, and draw Lewis structures (electron-dot diagrams) for given compounds. This worksheet has 7 fill in the blank, 5 short...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

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.

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

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

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

If you use this as an outline for your chemistry lecture on metals, your young chemists will absorb a well-rounded overview. This is not a worksheet per se, but a useful summary of the behavior of metals. Save yourself some planning and...

Designed to be a study guide or self assessment for high school biologists, the learning exercise has good questions about cell chemistry, but would need to be reformatted if you want your kids to write their answers on the paper. There...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.

In this reactions worksheet, students are given nine chemical reactions to identify as single replacement, double replacement, synthesis or decomposition reactions.

Every sort of chemical bond is touched upon during this assignment. Chemistry whizzes identify what type of bond is formed by analyzing chemical formulas or Lewis structure diagrams. Multiple choice questions also ask learners about...

In this chemical formulas worksheet, students practice naming molecular compounds by their formulas and determine if a gas is a compound or an element. This worksheet has 13 fill in the blank questions.

In this polar molecules worksheet, students complete a graphic organizer by writing in the bond type, electron dot diagram, and the type of compound for the chemical compounds given.

Students assume the role of police detectives and investigate chemical agents used to make explosives and suspected terrorists based on information provided. Students have a list of questions to lead their investigation and must produce...

Students measure the toxic levels of runoff and discuss the effects it would have on the aquatic system. In this runoff lesson plan, students answer questions to how runoff would affect the animals in an aquatic system.

In this limestone reactions worksheet, students read about the various types of limestone reactions and complete a diagram of deposits in a cave. They answer two questions about limestone reactions.

For this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that...

In this photosynthesis worksheet, students complete 20 various types of questions related to photosynthesis. First, they match each description in the first column with the correct vocabulary term in the second. Then, students explain...

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

In this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.

In this review of general science worksheet, students classify examples of matter as mixtures or substances, homogeneous or heterogeneous mixtures, or elements or compounds. Students also convert several examples using the standard...

Students explore the world of polymers. In this chemistry lesson, students make polymers and observe their properties. Follow-up questions and extension activities are included.
