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.
There is no narration in this video, just footage of a hand performing a chemical reaction set to magic-show-style music. Starting mass is shown in text. Solutions are mixed so that a precipitate forms, and then ending mass is shown. This brief video demonstrates the conservation of mass. It could be shown as you introduce the topic to young chemists.
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.
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 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.
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 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.
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.
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.
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.
Extremely short, this video is a computer animation of a double-pan balance with zinc and sulfur atoms on each side. The synthesis reaction between the two occurs, with the new zinc sulfide molecules. The balance is still balanced. This would be best used as part of a homework assignment; have your young chemists view it along with other video clips or the completion of a related worksheet.
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.
In this activity that integrates chemistry and algebra, learners solve systems of equations using matrices. The coefficients required to make chemical reaction balanced need to be determined.
In this atom activity, learners 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.
In this early atomic theory worksheet, 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.
In this matter learning exercise, students answer five questions about the law of conservation of mass. They identify substances as solids, liquids, gases or mixtures and they identify given items as matter or energy.
For this chemical reactions worksheet, students fill in 7 blanks, determine if 5 statements are true or false, match 5 terms with the appropriate definitions, and solve 3 problems. Students answer questions about chemical changes, the law of conservation of mass and chemical reactions.
Students discover the law of conservation of mass though experimentation. In this chemistry instructional activity, students experiment with acid - base indicators to determine the presence of carbon dioxide. Students complete the labs with analysis questions on chemical regents.
Students discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
Students research chemical components of coal, as well as environmental health impacts of mining and burning coal. They discuss conservation of mass as it relates to combustion of organic compounds.
