Fifth graders design an experiment in which they separate mixtures. In this mixtures instructional activity, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate the parts of a mixture.
Students observe and compare an element, compound and mixture. In this elements, compounds and mixtures lesson plan, student observe taco salad, a beaker of salt and a helium balloon. Students make lists comparing and contrasting the three samples. They identify the 3 samples as an element, compound and mixture. Students experiment with nuts, bolts and washers to represent elements, compounds and mixtures.
What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the class will learn that the unit rate is the same. Extend the lesson by applying to other common mixtures.
Students experiment with solutions. In this mixtures and solutions science lesson, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the different rates at which the cube dissolves depending on the variables.
Students explore mixtures and compounds. For this lesson, students do an experiment to distinguish between mixtures and compounds. Students complete ten different phases of the experiment testing many different substances. Students will gain knowledge of mixtures and compounds and how to test for them.
Here is an easy-to-use tool for deepening young chemists' understanding of elements, mixtures, and compounds. With colorful graphics, informative text, a photo gallery, and collection of short films, children of several learning styles will deepen their understanding of matter.
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?
