In this mixtures learning exercise, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous mixtures, and the comparison of mixtures and substances.
Middle school scientists compare and contrast heterogeneous and homogeneous mixtures. They differentiate solutions, colloids, and suspensions by examining samples of each. Note that the bulk of the lesson plan directs you how to incorporate a physical science video which is not available. Nonetheless, the activities and discussion involved are worthwhile if you don't mind sifting through the write-up.
This is a great worksheet with an infographic to assist your learners in categorizing matter into mixtures and non-mixtures. Information is given about the metric system of measurement. Your young students match 13 terms with their definitions, identify homogeneous and heterogeneous mixtures and identify elements and compounds. Learners make observations in the lab at 3 stations and record their discoveries of mixtures, elements and compounds.
In this mixture worksheet, students fill two test tubes with water and add starch to one and salt to the other. They stir the solutions and observe their appearance. They answer four questions about their mixtures and determine if they are homogeneous or heterogeneous mixtures.
Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight activities in all, along with 11 assessment questions. This resource is a valuable addition to your chemistry curriculum collection.
Although the images on the opening slide are not displayed, the slideshow itself is informative, orderly, and eye-catching. A graphic organizer sorts matter into its classifications: elements, compounds, and mixtures. Examples are given of each. Five slides on sulfur seem out of place, but can be hidden should you choose not to include them in this otherwise outstanding PowerPoint.
Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a mixture? How difficult is it to obtain pure substances?
Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and covalent bonds and give examples of physical and chemical changes in matter.
In this solutions, suspension and colloid worksheet, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of each and can test three for the Tyndall effect to help determine if the mixture is a colloid.
Students explore concrete. In this physical science and computer research lesson, students work in groups to answer specific questions about concrete. Each group of students completes a different worksheet with a specific subtopic. Students share their research with the whole class. Lesson plan structure, website lists, and specific topic questions are good examples of the "jigsaw" cooperative learning instructional procedure that could be adapted for many content areas.
In this matter worksheet, students review the characteristics of elements, compounds, and mixtures. Students identify matter changes as either physical or chemical. Students fill in the periodic table. This worksheet has 2 graphic organizer, 70 fill in the blank, 2 true or false, and 10 short answer questions.
