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 manmade 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
