Units of Study
Classify and describe matter using observable physical properties, including: temperature, mass, magnetism, relative density (sink/float), physical state
Investigate and compare a variety of mixtures including solutions that are composed of liquids in liquids and solids in liquids.
Demonstrate that matter is conserved when mixtures such as soil and water or oil and water are formed.
Plan and conduct descriptive investigations to explore the patterns of forces such as gravity, friction, or magnetism in contact or at a distance on an object.
Investigate and identify the transfer of energy by objects in motion, waves in water, and sound.
Identify conductors and insulators of thermal and electrical energy.
Demonstrate and describe how electrical energy travels in a closed path that can produce light and thermal energy.
Collect and analyze data to identify sequences and predict patterns of change in sequences such as changes in temperature and length of daylight.
Collect and analyze data to identify sequences and predict patterns of change in the observable appearance of the Moon from Earth.
Describe and illustrate the continuous movement of water above and on the surface of Earth through the water cycle and explain the role of the Sun as a major source of energy in this process.
Differentiate between weather and climate.
Model and describe slow changes to Earth's surface caused by weathering, erosion, and deposition from water, wind, and ice.
Identify and explain advantages and disadvantages of using Earth's renewable and nonrenewable natural resources such as wind, water, sunlight, plants, animals, coal, oil, and natural gas.
Explain the critical role of energy resources to modern life and how conservation, disposal, and recycling of natural resources impacts the environment.
Determine physical properties of rocks that allow Earth's natural resources to be stored there.
Investigate and explain how most producers can make their own food using sunlight, water, and carbon dioxide through cycling of matter.
Explore and explain how structures and functions of plants such as waxy leaves and deep roots enable them to survive in their environment.
Describe the cycling of matter and flow of energy through food webs, including the roles of the Sun, producers, consumers, and decomposers.
Identify and describe past environments based on fossil evidence, including common Texas fossils.
Differentiate between inherited and acquired physical traits of organisms.
