Science SCI.IV.1.2 Strand: Standard: Grade: 5 Using Scientific Knowledge in Physical Science Matter and Energy - All students will measure and describe the things around us. Benchmark: Explain when length, mass, weight, density, area, volume or temperature are appropriate to describe the properties of an object or substance. Constructing and Reflecting: SCI.I.1.2 - Design and conduct scientific investigations. SCI.I.1.4 - Use metric measurement devices to provide consistency in an investigation. • Experiment with metric measurement tools to demonstrate proper usage. Vocabulary / Key Concepts Context Measurement tools: Balances, spring scales, measuring cups or graduated cylinders, thermometers, metric ruler Common substances such as: • hot and cold substances, • ice, snow, cold water, • hot water, steam, cold air, hot air. • Desks • Coins • Pencils • Buildings • Wood • Plastic • Styrofoam • • • • • • • • • • • • • • • • • • • • • • • • • standardized units of measurement length metric ruler / tape centimeter / meter / kilometer foot / yard / mile width surface area square meters square feet volume cubic centimeters / milliliters cup / quart / gallon weight pounds Mass Balance Grams Pounds Temperature Celsius Fahrenheit Density Liquid = g/cm3 Solid = g/ml Pounds/cubic foot Knowledge and Skills Students will use and explain the appropriate measurements for describing the size of an object and amount of a substance. For instance, one wouldn’t measure a table in miles.

Focus Question: What is the appropriate equipment and metric units used to describe the size and amount of a substance? Set up workstations with the following instruments: metric ruler, metric stick, graduated cylinder, measuring cup (with printed measures on the side), spring scale, balance, and thermometer. Have students measure a variety of commonly found solids, and liquids (water, wood block, box, vegetable oil, rubbing alcohol, etc.). Have students in groups discuss their results and possible reasons for error. Going Beyond: Challenge the students to compare the volume and mass of an empty balloon and one filled with carbon dioxide that is formed when mixing vinegar and baking soda by using a two pan balance. Assessment Optional Assessment: Students will be given a variety of objects in which they choose 6 objects to create a chart which include estimate and actual measure of length, volume, mass, area and temperature. In the room, various measuring devices will be available for them to use. Before each measurement is made, students should estimate the measurement and include the unit of measure. Objects could include: different types of breakfast cereal of different shapes, dry and “wet”: breakfast cereal, water and different types of soda in varying quantities, different kinds of candy, powdered and liquid laundry detergent, classroom materials, and containers of different sorts. (Scoring rubric available on MI-CLiMB) Scoring Rubric Criteria: Correctness of units: Apprentice - Contains two or fewer correct units. Basic - Contains three to four correct units. Meets - Contains five or six correct units. Exceeds - Contains all correct units with additional objects measured. Criteria: Appropriateness of tool: Apprentice - Contains two or fewer correct choices of tools. Basic - Contains three to four correct measurements (+/- 2 units). Meets - Contains five or six correct choices of tools. Exceeds - Contains all correct choices of tools with additional objects measured. Criteria: Correctness of measurement: Apprentice - Contains two or fewer correct measurements. Basic - Contains three to four correct choices of tools. Meets - Contains five to six correct measurements (+/2 units). Exceeds - All objects are measured correctly within +/- 2 units. Teacher Notes: Scientists describe and compare objects and substances by measuring them using standardized equipment. Objects have size (length, area, volume), mass, weight and temperature. Substances have density (a property that is independent of the amount of the substance). (JCISD) Focus Questions • How can objects be described in terms of mass, volume and temperature? • When is it appropriate to measure the weight of an object rather than its mass, or density rather than volume?
