The student knows that systems have parts and are composed of organisms and objects. The student is expected to identify parts that, when separated from the whole, may result in the part or the whole not working, such as cars without wheels and plants without roots, and manipulate parts of objects such as toys, vehicles, or construction sets that, when put together, can do things they cannot do by themselves.
Physical Changes (K.7A)
Observe, describe, and record changes in size, mass, color, position, quantity, time, temperature, sound, and movement.
Changes from Heat (K.7B)
identify that heat causes change, such as ice melting or the Sun warming the air and compare objects according to temperature.
Systems, Structures, & Processes: Machines (1.6CD Note old 1998 TEKS)
Manipulate objects such as toys, vehicles, or construction sets so that the parts are separated from the whole which may result in the part or the whole not working; and identify parts that, when put together, can do things they cannot do by themselves, such as a working camera with film, a car moving with a motor, and an airplane flying with fuel.
Physical Changes (1.7A Old 1998 TEKS)
Observe, measure, and record changes in size, mass, color, position, quantity, sound, and movement.
Changes from Heat (1.5B) Updated
Predict and identify changes in materials caused by heating and cooling such as ice melting, water freezing and water evaporating.
Physical Changes (2.5A)
Classify matter by physical properties including shape, relative mass and temperature, texture, flexibility and whether material is solid or liquid
Changes from Heat (2.7B)
Identify, predict, and test uses of heat to cause change such as melting and evaporation.
Force and Motion (2.7C)
Demonstrate a change in the motion of an object by giving the object a push or a pull.
Force and Motion (3.6B) Updated
Demonstrate and observe how position and motion can be changed by pushing and pulling objects to show work being done, such as swings, balls, pulleys and wagons.
Classifying Matter (3.5A & 3.6C) Updated
Gather information including temperature, magnetism, hardness, and mass using appropriate tools to identify physical properties of matter; and identify matter as liquids, solids, and gases.
Identify and describe the roles of some parts of nonliving systems such as a light bulb in a circuit, and predict and draw conclusions about what happens when part of a system is removed.
Identify patterns of change
Patterns of Change: Symmetry (math-science connections)
Illustrate that certain characteristics of an object can remain constant even when the object is rotated like a spinning top, translated like a skater moving in a straight line, or reflected on a smooth surface, and use reflections to verify that a natural object has symmetry.
Changes from Heat (4.5B) Updated
Predict the changes caused by heating and cooling, such as ice becoming liquid water and condensation forming on the outside of a glass of ice water.
Forms of Energy (4.6A) Updated
Differentiate among forms of energy including mechanical, sound, electrical, light and heat/thermal.
GCCE Greenhouse Earth (5.8A) Updated
Describe the physical processes that create the earth's greenhouse effect. Identify several greenhouse gases and their major sources. Explain the “enhanced greenhouse” effect.
GCCE Light and the Earth (5.6C) Updated
Describe the relationship between absorption and reflection of sunlight and its conversion to thermal energy. Describe the reflection of sunlight as the albedo effect. Describe the basic albedo of various objects
GCCE Energy of the Sun and Earth (5.6A ) Updated
Describe sunlight and heat in terms of their energy. Describe the transformation of sunlight to heat. Discuss how materials affect energy transformation.
GCCE Atmosphere Mixture (5.5C) Updated
Describe earth’s atmosphere as a mixture of solids, liquids, and gases. Identify common gases of the atmosphere, i.e. N2, O2, CO2, and H2O. Describe the physical and/or chemical properties of the air mixture. Demonstrate the separation and addition of mixture components
GCCE Properties of the Atmosphere (5.5A) Updated
Learn about the atmosphere as a protective layer around the earth. Identify common solids, liquids, and gases in the atmosphere. Classify components of the atmosphere according to physical properties. Describe the transformation of components from one state to another.
Mixtures and Solutions (5.5CD) Updated
Demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand. Identify changes that can occur in the physical properties of the ingredients such as dissolving salt in water or adding lemon juice to water.
Properties of water (5.5B) Updated
Identify the boiling and freezing/melting points of water on the Celsius scale.
Light (5.6C) Updated
Demonstrate that light travels in a straight line until it strikes an object or travels from one medium to another and demonstrate that light can be reflected, such as the use of mirrors or other shiny surfaces, and refracted, such as the appearance of an object when observed through water
Circuits and Electricity (5.6B) Updated
Demonstrate the flow of electricity in circuits requires a complete path through which an electric current can pass and can produce light, heat, and sound
Classifying Matter (5.5A) Updated
Classify matter based on physical properties including mass, magnetism, physical state (solid, liquid, gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal or electric energy.
