In this chemical reactions worksheet, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This worksheet has 3 problems to solve.
Describing a Chemical Reaction
In this chemical reactions learning exercise, students compare physical changes and chemical reactions. Students learn to balance chemical equations. This learning exercise has 10 short answer questions.
Energy in Chemical Reactions
In this chemical reaction worksheet, learners determine if reactions are exothermic or endothermic. Students define enthalpy and calculate how much heat is released or absorbed during reactions. This worksheet has 1 matching, 1 fill in the blank, 1 short answer question, and 5 problems to solve.
Nye: Chemical Reactions
In this "Bill Nye: Chemical Reactions" worksheet, students watch the movie and respond to 19 fill in the blank questions regarding information from the documentary on chemical reactions.
In this chemical reactions learning exercise, students describe catalyst, enzyme, and activation energy. Students use two graphs of chemical reactions to determine activation energy. This learning exercise has 4 fill in the blank and 6 short answer questions.
Chemical Reactions and Balancing Equations
Students perform various laboratory activities involving chemical reactions. They write balanced chemical equations for all reactions observed using computer software.
The Rates of Chemical Reactions
In this chemistry instructional activity, students complete a crossword puzzle with 25 questions on chemical reactions. They identify common terminologies used in describing chemical reactions.
5 Types of Chemical Reactions and a Lab on Mole
Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a sample of water.
Rates of Chemical Reactions
Review key terms after your lecture about chemical reactions with this crossword puzzle. Eleven questions prompt students to refer to their textbooks, lecture notes, and prior knowledge. This assignment would be a good homework assignment or quiz review activity.
Classifying Chemical Reactions
In this chemical reactions worksheet, students compare the different types of chemical reactions and then classify the given reactions. This worksheet has 5 fill in the blank and 2 short answer questions.
Chemical Reactions Quiz Review Sheet
In this chemical reactions learning exercise, students balance an equation, determine the type of reaction, and write the net ionic equation. This learning exercise has 5 problems to solve.
Balancing Chemical Reactions
In this balancing chemical reactions worksheet, students answer 12 questions about balancing reactions. They find the coefficients to balance atoms in equations, they balance reactions, they find the molecular mass of molecules and they write compounds in reaction notation.
Fifth graders investigate chemical reactions. For this chemical reactions lesson, 5th graders create polymer snow powder and make predictions regarding their creation of a second polymer.
In this chemical reactions instructional activity, learners give a definition and example of each of the terms listed. Students tell the evidence of a chemical reaction in the examples provided.
How Can we Measure the Rate of a Chemical Reaction?
Pupils examine different types of chemical reactions. They explore how alcohol molecules affect the reaction rates. They answer discussion questions to end the lesson.
Rates of Chemical Reactions: Combustion Reactions
How does a burning candle represent a combustion reaction? Use this activity to reinforce your young chemists' knowledge of chemical reactions. After drawing a picture of a lit candle and labeling it accordingly (no actual candle is required, but you could use one anyway), students answer two questions about the combustion reaction they are seeing. This activity would be a good homework activity after a lecture on combustion.
Classifying Chemical Reactions
Summarize your topic of chemical reactions with this short presentation about classifying and the properties of different reaction types. Your students should be able to name the reaction types, identify the ions involved, and write the equations for the covalent and ionic compounds. Sets of slides could be used to present information in single lessons, or all 9 would be a good review to assist in making notes.
Follow Up Questions Lab 1-Chemical Reactions
In this chemical reactions worksheet, students answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions about their lab results.
Describing a Chemical Reaction: Playing with Copper
Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two experiments involve minimal lab materials and could be done in one or two class sessions. Each experiment requires a short answer, which could be expanded into a lab report.
Chemical Reactions Homework Problem Set
In this chemical reactions practice worksheet, students balance 6 equations and give the name of the reactants and the products. In addition, students balance 3 equations and determine the molecular formula and the molecular weight of each species.
