|Unit of Instruction||Matter, Changes in Matter, Mixtures and Solutions|
SC.5.P.8.1 – Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature.
SC.5.P.9.1 – Investigate and describe that many physical and chemical changes are affected by temperature.
SC.5.P.8.3 – Demonstrate and explain that mixtures of solids can be separated based on observable properties of their parts such as particle size, shape, color, and magnetic attraction.
SC.5.P.8.2 – Investigate and identify materials that will dissolve in water and those that will not and identify the conditions that will speed up or slow down the dissolving process.
|Learning Targets and Learning Criteria|
SC.5.P.8.1- Students will:
• review by describing and classifying a material as a solid, liquid, or gas.
• review how to use the water displacement method to find the volume of regular- and irregular-shaped solids.
• justify the reasoning for the classification of materials based on shape, mass (weight) and volume (water displacement).
• recognize that physical properties include both observable and measurable properties.
• compare and contrast the observable properties of solids, liquids, and gases (e.g., shape, color, hardness, texture, taste, attraction to magnets).
• compare and contrast the measurable properties of solids, liquids, and gases (e.g., mass, volume, temperature).
SC.5.P.9.1 Students will:
• review the causes for the weathering of rocks (ice wedging, precipitation and flowing water, abrasion of particles carried by the wind, plant roots, temperature change)
• review the causes for the erosion of rocks (gravity, ice/glaciers, flowing water, wind).
• review by describing visible signs of a chemical change that may occur (odor, color change, temperature change, gas production/fizzing sound).
• review by comparing the similarities and differences of physical and chemical changes.
• investigate and describe that many physical changes to solids and liquids are affected by temperature change (e.g., melting, freezing, evaporating, condensing, dissolving).
• investigate and describe how temperature can cause a chemical change that results in the formation of a new material with different characteristics (e.g., baking, grilling, frying, toasting, decaying plant and animal matter, rusting, releasing of carbon dioxide).
SC.5.P.8.3 & SC.5.P.8.2 Students will:
• demonstrate and explain how mixtures of solids can be separated based on observable properties of their parts (e.g., particle size, shape, color, magnetic attraction) through sorting, screening-sieve, filtration, magnets, and evaporation.
• investigate common household materials (liquids or solids) that will dissolve in water (e.g., salt, sugar, drink mixes) and those that will not (e.g., rice, beans, cooking oil, lard).
• recognize that not all parts of a mixture will dissolve.
• investigate the conditions (temperature, stirring/shaking, surface area) that will speed up or slow down the dissolving process and/or chemical reactions (e.g., heat speeds up reactions and the dissolving process).
