Students measure the heat of physical and chemical changes in reactions. In this chemistry lesson students determine at what extent changes emit or absorb heat.
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the conventional step-by-step manner. A worksheet is provided with questions to help learners process their observations. Although this was written for a high school chemistry course, it seems more appropriate for middle schoolers.
Students compare and contrast the five major types of chemical reactions. They participate in a demonstration called "Elephant Toothpaste" and predict which type of reaction will occur. After the demo the write a reflection in their journals.
Students study chemical reactions and how to speed up or slow down one. In this experimental lesson students participate in an activity that allows them to observe chemical reactions.
In this chemistry worksheet, students investigate 15 different chemical reactions using the internet. They classify them according to their correct type.
Students understand the difference between four different types of chemical reactions: composition, synthesis, single replacement, and double replacement and identify the type of reaction and predict the products of these types of reactions.
In this chemical reaction worksheet, students balance the given chemical reactions. Students decide which statements are true about chemical reactions. Students also calculate the number of moles, grams, or molecules will be produced in a chemical reactions.
In this chemical reactions activity, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This activity has 3 problems to solve.
In this chemical reactions worksheet, students compare physical changes and chemical reactions. Students learn to balance chemical equations. This worksheet has 10 short answer questions.
In this chemical reaction worksheet, students 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.
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 worksheet, high schoolers describe catalyst, enzyme, and activation energy. Students use two graphs of chemical reactions to determine activation energy. This worksheet has 4 fill in the blank and 6 short answer questions.
Students perform various laboratory activities involving chemical reactions. They write balanced chemical equations for all reactions observed using computer software.
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.
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.
In this chemical reactions learning exercise, students compare the different types of chemical reactions and then classify the given reactions. This learning exercise has 5 fill in the blank and 2 short answer questions.
In this chemistry worksheet, students complete a crossword puzzle with 25 questions on chemical reactions. They identify common terminologies used in describing chemical reactions.
In this chemical reactions worksheet, students balance an equation, determine the type of reaction, and write the net ionic equation. This worksheet has 5 problems to solve.
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. In this chemical reactions lesson, 5th graders create polymer snow powder and make predictions regarding their creation of a second polymer.
