Proficiency Standards By the End of Grade Two Students will be able to: Invent their own unit of measurement (e.g., the room is nine &quot;Nancys&quot; wide) Explain the need for standard universal measurement units (e.g., initiated by measuring width of room using one's own feet and a meter stick) Measure net mass (e.g., subtracting mass of container holding some material whose mass is to be measured) Use rulers, thermometers, and balances to observe, measure, and construct objects By the End of Grade Four Students will be able to: Invent a tool or device for accomplishing a particular measurement task or goal Compare the usefulness of various devices and measurement units for accomplishing a particular measurement task Use tools such as balances, graduated cylinders, tape measures, and stopwatches to make accurate and precise measurements By the End of Grade Six Students will be able to: Use an assortment of measuring instruments, with a variety of scales, such as rulers, thermometers, graduated cylinders, balances, and timers Describe and practice appropriate techniques for using simple measuring devices Use technology to explore events in nature, e.g., telescopes, microscopes, computer probes 2b. Curriculum Standard: Students will demonstrate an increasing ability to use technology to observe nature.
