Grade 3, Science Std 1: Classify substances as soluble or insoluble. Examples: soluble—sugar in water, powdered drink in water; insoluble—sand in water, oil in water

Lesson Plans: Homogenous and Heterogeneous Mixtures Student will distinguish between the two types of mixtures which are heterogeneous and homogenous. Sensational Slime Predicting, observing, and drawing conclusions are key elements in the scientific process. This activity is designed to foster utilization of these skills while performing a hands-on experiment. Making Ice Cream! Each student will complete a recipe for ice cream in the bag. Mixtures Students will experiment with several variables, against a control, to observe the different rates that a solute (sugar) dissolves in a solvent (water) to form a solution. Homogenous and Heterogeneous Mixtures Student will experiment and record findings. Mixtures Variables affecting the rate of the dissolving of a substance (solute) in water (solvent) are discussed and observed through experimentation. Compared to What? Comparing the Density of Different Liquids: Students will understand that different liquids have different densities. Homogenous and Heterogeneous Mixtures Students will learn how to distinguish between homogenous and heterogeneous mixtures. Rate of Solubility Students explore the factors affecting the rate of solubility. This lesson can be adapted for any grade. Solubility In this lesson, students will tell the difference between a soluble and an insoluble solution. Structure of Matter Students will learn about mixtures, including solutions and suspensions. Why Is the Sea Salty? Students will observe how salt concentration increases in water. Solutions and Mixtures This lesson plan is Activity 8 in the unit Matter and Its Changes. Scroll down the pages to Activity 8.

Resources: Chem4Kids Resources for matter Science Online A must see! Great site for links to Blueprint Skills, Lesson Plans, Topical Sites, Interactive Websites for Students and Worksheets Science Clips You will find an alphabetical list of science interactive movie clips. Suspensions and Solutions This is a printable lab observation report for solutions. Matter This unit has a great concept web for matter and mixtures. Layered Liquids This experiment main purpose is density. However, It is a good experiment for showing insolubility of liquids.
