New! Conservation of Mass
How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the balloon expand, showing that gas can be captured, which means it has mass. They weigh the masses of the reactant before and after the experiment and discuss the results.
Conservation of Mass
In this conservation of mass worksheet, learners experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the experiment to observe the conservation of mass. Students answer 5 questions and write a conclusion about their experiment.
The "Laws" and Principles of Chemical Reactions
In this chemical reaction principles learning exercise, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short answer questions, and 2 problems to solve.
Project EASE Module 13: Chemical Reactions
Four lessons can be found in this chemistry resource. A pretest is provided, and then young chemists explore the law of conservation of mass in chemical reactions. Then they learn about the laws of definite and multiple proportions. In the end they practice writing and balancing equations. The lessons all consist simply of printed instruction, sample problems, and a few practice problems. There is also a post-test and answer key. Give the packet to your class to work through at home, and then have them come to class to put it all into practice!
No Creation-No Destruction--All in a Baggie
Students investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions created specific observations.
The Conservation Of Mass (The Mass Of Gas)
Middle schoolers gain an understanding of matter in all of its phases. In this science lesson plan, students further their knowledge of the laws of conservation of mass, the loss in mass can be accounted for, when the gas is allowed to escape from the container which it is produced in.
Conservation of Mass
In this conservation of mass worksheet, students design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.
The "Laws" and Principles of Chemical Reactions
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.
The Chemistry of Coal
Students investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental health impacts of mining and burning coal.
What Is Inside the Atom?
Four lessons make up this mini unit about atomic structure and spectra. A pretest is provided to give an idea of what is already known about the atom. Through a series of demonstrations and lecture, you present the information to young chemists. They construct a fruit model of the boron atom. They fill in a chart using the periodic table of elements. They compare and contrast two potatoes as an example of how isotopes are related. Asides from the dissection of a fried fish head, this is a terrific set of lessons for introducing the atom and radioactivty.
What is a Chemical Reaction?-Evidence of Change
In this chemical reactions instructional activity, students experiment with hydrochloric acid and copper (I) chloride to identify the types of reactions they undergo with various other substances. They also observe the law of conservation of mass and record their observations of chemical reactions.
Chemical Formulas for Molecules
Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical reactions are set up to help learners identify evidence of a chemical reaction and understand the conservation of mass. Plenty of practice applying learned concepts is also provided through a series of assessment assignments. You can breathe easy using this resource as a guide to teaching chemical formulas.
Beads, Balls, and Beakers
Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being packed into a tiny area.
Balancing Chemical Equations Lesson Plan
High schoolers observe how to balance chemical equations and explore how to write formulas. In this chemistry lesson students balance chemical equations and visualize the concept by observing an experiment using one of the equations.
Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This will save you time in creating individual informative slides, but you might want to rearrange them in a way that is more coherent. Also, you probably would not want to teach all of this material in one day! Please also note that hyperlinks to worksheets do not work.
What are Atoms?
In this atom worksheet, high schoolers read about Dalton's contributions to the structure of the atom. They answer five questions about Dalton's ideas, the law of multiple proportions and the law of definite proportions.
COMPOSTING: WHY BOTHER?
Students explore the composting process and participate in a contest to make the most compost the fastest from the school's kitchen and yard waste.
Introduction to Materials Science - Part B
Students are able to give specific examples of what to do and what not to do during given safety situations, and classify materials as metals, polymers, ceramics/glass, or composites. They are able to distinguish between chemical and physical properties and chmeical anc physical changes.
Early Atomic Theory Homework
In this early atomic theory instructional activity, students answer 4 questions about the Law of Definite Proportions, the Law of Conservation of Mass and Dalton's Laws. Students are given 5 statements to determine if each true statement supports or refutes Dalton's Laws.
Everything about Equations
In this chemical reactions worksheet, students are given fifteen unbalanced equations and they must identify the reaction types, the phases of the products, the signs that a chemical change occurred and the sum of the coefficients of the balanced equations.
