TEKS for Middle School Science How the TEKS are Integrated into the Lesson (6.1) (7.1) (8.1) The students make wise choices in the use and conservation of resources and the disposal of materials. Through the Introduction, students will learn that changes in pH can be the result of natural phenomena or man-made events such as acid rain. (6.2) (7.2) (8.2) The student will conduct different experiments and use scientific methods to record and interpret their observations. Through the Activity, students will perform a scientific experiment and observe the behavioral patterns of fish living in environments with high and low pH values. (6.4) (7.4) (8.4) The student will collect, analyze, and record information using several tools. The student will also identify patterns in collected information using average values. Through the Presentation, students will learn the methods of measuring pH by using tools such as- chemical strips and pH meters. Through the activity in the Presentation, students will observe the pH values for different bodies of water and compare the average pH value for each body of water with the pH range of each organism located on an online chart (6.11) (7.11) (8.11) The students will know the effects of different environmental conditions on the survival of organisms. Through the Presentation, students will learn the effects of changes in pH range on the survival of organisms. (e.g.- most adult fish die if the pH range is low) (6.12) (7.12) (8.12) The student knows how different environments support different varieties of organisms. Through the Presentation, students will learn the survival of certain organisms in specific pH range- either acidic, neutral or basic
 TEKS for Middle School Mathematics How the TEKS are Integrated into the Lesson (6.2) (7.2) (8.2) The student adds, subtracts, multiplies and divides to solve problems and justify solutions. Through the Presentation, students will learn to use addition, multiplication and division of whole numbers to solve problems. (6.5) The student uses letters to represent an unknown in an equation. Through the Presentation, students will learn to use letters to represent an unknown in an equation. (6.10) (8.13) The student uses statistical representations to analyze data. Through the Presentation, students will solve problems by collecting, organizing, displaying, and interpreting data. (6.11) (7.13) (8.14) The student applies Grade 6 mathematics to solve problems connected to everyday experiences, investigations in other disciplines, and activities in and outside of school. Through the Presentation and Activity, students will learn to select tools such as paper/pencil, technology or techniques such as mental math and estimation to solve problems. (6.13) (7.15) (8.16) The student uses logical reasoning to make conjectures and verify conclusions. Through the Presentation, students will validate his/her conclusions using mathematical properties and relationships. (7.1) The student represents and uses numbers in a variety of equivalent forms. Through the Presentation, students will learn to convert between fractions, decimals, and whole numbers mentally, on paper or with a calculator. (7.11) The student understands that the way a set of data is displayed influences its interpretation. Through the Presentation, students will make inferences and convincing arguments based on an analysis of given or collected data. (8.1) The student understands that different forms of numbers are appropriate for different situations. Through the Presentation, students will learn to express numbers in scientific notation, including negative exponents, in appropriate problem situations using a calculator. (8.5) The student uses graphs and tables to make predictions and solve problems. Through the Presentation, students will learn to estimate and justify solutions using an appropriate graph. Through the Activity, students will use a table to record their observations and make predictions based on the pH range of a body of water against the pH range of each organism.
 TEKS for Middle School Technology How the TEKS are Integrated into the Lesson (1) Foundations The student demonstrates knowledge and appropriate use of hardware components, software programs, and their connections. Throughout the lesson, students will use terminology including, but not limited to, World Wide Web (WWW), link, Internet, Uniform Resource Locators (URLs), and web page. (2) Foundations The student uses data input skills appropriate to the task. Students will demonstrate proficient use of the mouse and keyboard, as they navigate through the lesson and related web pages. (3) Foundations The student complies with the laws and examines the issues regarding the use of technology in society. While following links on the Internet and using the World Wide Web (WWW), the student will demonstrate proper etiquette and knowledge of acceptable computer use in the classroom or lab. (4) Communication The student forms digital information for appropriate and effective communication The students are expected to fill out the activity sheets provided which could be useful in communicating their information on the behavioral patterns of organisms in different oxygen levels
