6.1BPractice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials

The student uses scientific practices inquiry methods during laboratory and field investigations. The student is
expected to:

TEKSLessons
6.2APlan and implement comparative and descriptive investigations by making observations, asking well defined questions, and using appropriate equipment and technology

6.2BDesign and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology

6.2CCollect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers

6.2DConstruct tables and graphs, using repeated trials and means, to organise data and identify patterns

6.2EAnalyze data to formulate reasonable explanations, communicate valid conclusions supported by the data, and predict trends

The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions and knows
the contributions of relevant scientists. The student is expected to:

TEKSLessons
6.3AAnalyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student

6.3BUse models to represent aspects of the natural world such as a model of Earth’s layers

6.3CIdentify advantages and limitations of models such as size, scale, properties, and materials

6.3DRelate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content

The student knows how to use a variety of tools and safety equipment to conduct science inquiry. The student is
expected to:

TEKSLessons
6.4AUse appropriate tools, including journals/ notebooks, beakers, petri dishes, meter sticks, graduated cylinders, hot plates, test tubes, balances, microscopes, thermometers, calculators, computers, timing devices, and other necessary equipment to collect, record and analyze information
6.4BUse preventative safety equipment, including chemical splash goggles, aprons, and gloves, and be prepared to use emergency safety equipment, including an eye/face wash, a fire blanket, and a fire extinguisher

The student knows the differences between elements and compounds. The student is expected to:

TEKSLessons
6.5AKnow that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula

6.5BRecognize that a limited number of the many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere

6.5CIdentify the formation of a new substance by using the evidence of a possible chemical change such as production of a gas, change in temperature, production of a precipitate, or color change

The student knows matter has physical properties that can be used for classification. The student is expected to:

TEKSLessons
6.6ACompare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability

6.6BCalculate density to identify an unknown substance

6.6CTest the physical properties of minerals, including hardness, color, luster, and streak

The student knows that some of Earth’s energy resources are available on a nearly perpetual basis, while others can be renewed over a
relatively short period of time. Some energy resources, once depleted, are essentially nonrenewable. The student is expected to:

TEKSLessons
6.7AResearch and discuss the advantages and disadvantages of using coal, oil, natural gas, nuclear power, biomass, wind, hydropower, geothermal, and solar resources

The student knows force and motion are related to potential and kinetic energy. The student is expected to:

TEKSLessons
6.8ACompare and contrast potential and kinetic energy

6.8BIdentify and describe the changes in position, direction, and speed of an object when acted upon by unbalanced forces

6.8CCalculate average speed using distance and time measurements

6.8DMeasure and graph changes in motion

6.8EInvestigate how inclined planes can be used to change the amount of force to move an object

The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just
changes form. The student is expected to:

TEKSLessons
6.9AInvestigate methods of thermal energy transfer, including conduction, convection, and radiation

6.9BVerify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting

6.9CDemonstrate energy transformations such as energy in a flashlight battery changes from chemical energy to electrical energy to light energy

TEKSLessons
6.10ABuild a model to illustrate the compositional and mechanical layers of Earth, including the inner core, outer core, mantle, crust, asthenosphere, and lithosphere

6.10BClassify rocks as metamorphic, igneous, or sedimentary by the processes of their formation

6.10CIdentify the major tectonic plates, including Eurasian, African, Indo-Australian, Pacific, North American, and South American

6.10DDescribe how plate tectonics causes major geological events such as ocean basin formation, earthquakes, volcanic eruptions, and mountain building
