Supported TEKS

5.1 Mathematical process standards. The student uses mathematical processes to acquire and
demonstrate mathematical understanding. The student is expected to:

(A) apply mathematics to problems arising in everyday life, society, and the workplace;

5.3 Number and operations. The student applies mathematical process standards to develop and use
strategies and methods for positive rational number computations in order to solve problems with
efficiency and accuracy. The student is expected to:

(A) estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division;

5.1 Scientific investigation and reasoning. The student conducts classroom and outdoor investigations following home and school safety procedures and environmentally appropriate and ethical practices. The student is expected to:

(B) make informed choices in the conservation, disposal, and recycling of materials.

5.3 Scientific investigation and reasoning. The student uses critical thinking and scientific problem solving to make informed decisions. The student is expected to:

(C) connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists.

5.5 Matter and energy. The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used. The student is expected to:

(C) identify changes that can occur in the physical properties of the ingredients of solutions such as dissolving salt in water or adding lemon juice to water.

5.8 Earth and space. The student knows that there are recognizable patterns in the natural world and among the Sun, Earth, and Moon system. The student is expected to:

(A) differentiate between weather and climate;

(B) explain how the Sun and the ocean interact in the water cycle;

5.8 Geography. The student understands how people adapt to and modify their environment. The student is expected to:

(A) describe how and why people have adapted to and modified their environment in the United States such as the use of human resources to meet basic needs; and

(B) analyze the positive and negative consequences of human modification of the environment in the United States.
