Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: This promising practice resource is a hands-on inquiry that asks students to design a bridge given specific constraints under which to work. This lesson is strongest when used during a unit on forces or technology, as this lesson emphasizes science processes rather than science content. (author/cb) 922 Using Current Data for Graphing Skills Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: This promising practice resource focuses on graphing and is designed to help students identify the difference between an effective and ineffective graph, draw their own graphs, and interpret and relay information in a graph into another form of communication. This lesson requires the use of computers and the Internet and will be most effective if real-time scientific data is used, as is found in the following ORC resources: USGS Real-time Water Data for the Nation, U.S.... Projects: COR 923 Exploring the Physical and Chemical Properties of Polymers Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 9–10 Professional Commentary: This promising practice resource involves students in an inquiry-based examination of the physical and chemical properties of polymers. By the end of this lesson, students should be able to operationally apply physical and chemical property definitions to specific examples, discuss that plastics are polymers that can be categorized into six types, and identify physical and chemical properties and differences in polymers.It is important to note that this lesson asks students to use various chemicals, some of which require the use of a fume hood. If a fume hood is not available, the chemicals that require a fume hood should not be used.Also, this resource asks teachers to refer to MSDS sheets. See ORC Resource #4815 for a comprehensive list of the MSDS sheets for the chemicals required in this lesson as well as many more. (author/cb) 924 Heat Loss and Gain in Physical Changes and Chemical Reactions Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 9–10 Professional Commentary: In this promising practice lesson students measure both qualitatively and quantitatively the heat of physical changes and a chemical reaction. Students dissolve various compounds in water to determine if the process is exothermic or endothermic.... 925 How Are Polymers Utilized in Everyday Life? Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 9–12 Professional Commentary: This is a promising practice resource designed around the topic of polymer science. Students use the Macrogalleria website to gather polymer information, put it into a graphic organizer and then present their polymer information to the class. By the end of the lesson, students should be able to identify chemical and physical properties of the polymer, explain how it's used in everyday life, describe the pros and cons of using this polymer, and identify how the polymer has improved over time. (author/cb) Projects: COR Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: In this promising practice resource, students examine mystery polymers by observing physical properties and analyzing their physical changes. This resource gets students to think about polymers, and the fact that there are polymers other than plastics all around them. Use, or have students use ORC Resource #36, Macrogalleria, in conjunction with this resource, as it does an excellent job of relating polymers to students' everyday lives. (author/cb) Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: Through hands-on activities and inquiry, students will construct a simple calorimeter. Students will determine the number of calories in a sample of food through experimentation and simple calculation. Through the use of the Internet, students will plan a meal and calculate the number of calories the meal contains.... Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: In this promising practice lesson, three substances are mixed in a sealed plastic bag causing a chemical reaction to occur. The reaction causes the bag to get warm and expand while the color of the contents of the bag changes. As a result of this lesson, students will design simple experiments to determine the role of each chemical in the reaction. Students should be able to identify which mixture of chemicals caused the color to change, temperature to change, and gas to be produced. (author/cb) 929 Movement With Functions: Road Rage Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: In this lesson, students use remote-controlled cars to create a system of equations. The solution of the system corresponds to the cars crashing.... Resource Type: Instructional Resource -- Promising Practice Discipline: Science Ohio Standards Alignment: Grades 6–8 Professional Commentary: This is an excellent promising practice resource demonstrating that air has mass and exerts a force called air pressure. Throughout this lesson students will begin to understand that forces may be either balanced or unbalanced. They will also develop scientific process skills that will enable them to gain an understanding of the need to identify and control variables. (author/cb) |
