In this conservation of mass worksheet, students 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.
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!
Students 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.
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.
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.
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.
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.
In this chemical reactions 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.
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.
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.
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 chemical equation must have the same number and types of atoms on each side of the arrow.
