Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: In this promising practice lesson, students will learn how telescopes work, will build a model of their own, and will consider how real telescopes can be used to ask-and help answer-questions about the universe. This is an excellent lesson for getting students to understand the relationship of technology and science.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics, Science Ohio Standards Alignment: Grades 3–5 Professional Commentary: By flipping coins, pulling marbles out of a bag, and playing with an online applet, students develop a basic understanding of probabilities, how they are determined, and how the outcome of an experiment can be affected by the number of times it is conducted. This lesson supports the development of scientific and mathematical processes such as... Projects: COR Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: The purpose of this lesson is to determine the pattern (length and direction) of shadows cast by sunlight over several months to develop an interpretation of the daily and seasonal patterns and variations observed. Students are then asked to make a table of the times, lengths of lines, and angles for the shadow data....

In this lesson, students build and reflect on the usefulness of models that demonstrate the water cycle in a closed system.... 425 Plasmolysis in Elodea Plant Cells Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 9–10 Professional Commentary: In this lesson, students observe chloroplasts, cell walls, and cell membranes of the common aquarium plant, Elodea. Students will then determine the effects of different salt solutions on the Elodea plant cell structures.... Career Fields: Agricultural & Environmental Systems, Health Science Projects: Standards First Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 3–5 Professional Commentary: The purpose of this lesson is to investigate familiar and unfamiliar ecosystems using Internet resources; to explore how various organisms satisfy their needs within their environments; to study the kinds of relationships that exist between organisms within an environment. (author) 427 Pond 2: Life in a Drop of Pond Water Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 3–5 Professional Commentary: The objective of this promising practice lesson is to investigate the living creatures in a drop of pond water. Students travel to a local pond where they collect samples of pond water.... 428 Pottery 2: Pots and People Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: The purpose of this promising practice lesson is to develop an understanding of the human perspective in the history of pottery making and ceramics. This lesson provides students with a context in which to compare present technology with that of earlier times.... Career Fields: Arts & Communication, Manufacturing Technologies Projects: Standards First Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 3–8 Professional Commentary: In this best practice lesson students test their visual and auditory abilities (both separately and together) as they play an online game and record their reaction times. This lesson could be used to model data collection, representation, and analysis.... Projects: COR Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 9–12 Professional Commentary: In this promising practice lesson, students will explore design considerations of model rockets. They will consider how model rockets are similar to real rockets (in design and flight), as well as how they are different due to the constraints placed upon them such as size and intended user....
