Standards: Mass, Volumes, & Concentrations

TEKS for Middle School Science	How the TEKS are Integrated into the Lesson
(6.2) (7.2) (8.2) The student uses scientific inquiry during field and laboratory investigations.	During the Activity, students will calculate, interpret, and analyze the relationships between mass, volume and concentration. Students will also record their results in the worksheet that is provided.
(8.3) The students will analyze, review, and critique scientific explanations using scientific evidence and information.	During the Presentation, students will learn the scientific explanations including the hypotheses, quoted along with examples to simplify the scientific concepts.
(6.4) (7.4) (8.4) The student knows how to use a variety of tools and methods to conduct science inquiry.	Through the Presentation, students will learn the different units of measurements which are useful in analyzing and recording information. Through the Activity, students will use tools including beakers, stirrers and calculators.

TEKS for Middle School Mathematics	How the TEKS are Integrated into the Lesson
(6.2) (7.2) (8.2) The student multiplies and divides to solve problems and justify solutions	During the Activity, students will use multiplication and division of whole numbers to solve problems.
(6.8) (7.9) The student solves application problems involving estimation and measurement.	During the Activity, students will select and use appropriate units, tools, or formulas to solve problems.
(6.10) (8.13) The student uses statistical representations to analyze data.	Through the Activity, 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 Activity, students will select tools such as paper/pencil, 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 Activity, students will validate his/her conclusions using mathematical properties and relationships.

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 formats digital information for appropriate and effective communication.	The students will be required to fill in the activity sheets which are provided. This activity could be useful in communicating information of the relationships between mass, volume and concentration.
