5th Grade Science Unit 2

Big Idea:

Matter has measurable physical properties and those properties determine how matter is classified, changed, and used.

Student Expectations:

Priority TEKS

5.5A Classify matter based on measurable, testable, and observable physical properties, including mass, magnetism, physical state (solid, liquid, gas), relative density (sinking and floating using water as a reference point), solubility in water, and the ability to conduct or insulate thermal energy or electric energy

Focus TEKS

5.4A collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, prisms, mirrors, pan balances, triple beam balances, spring scales, graduated cylinders, beakers, hot plates, meter sticks, magnets, collecting nets, and notebooks; timing devices, including clocks and stopwatches; and materials to support observations of habitats or organisms such as terrariums and aquariums

5.5B Demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand or sand and water;

5.5C identify changes that occur in the physical properties of the ingredients of solutions such as dissolving salt in water or adding lemon juice to water.

Ongoing TEKS

5.1A use safety equipment, including safety goggles and gloves.

5.1B Make informed choices in the conservation, disposal, and recycling of materials.

Student Learning Targets:

• I will classify matter according to its physical properties.
• I will compare the mass of different objects.
• I will write to compare and contrast the physical state of matter.
• I will determine what types of matter are magnetic.
• I will relate sinking and floating in water to the density of matter.
• I will organize objects based on the ability to conduct heat or electricity.
• I will recognize that some materials will dissolve when mixed in water.

Essential Questions:

• How can you measure the different properties of matter?
• According to which physical properties can the following objects be separated/categorized?
• What does it mean if one object sinks while another object floats?
• Which physical property is the most helpful in classifying matter?
• How does heat affect matter?
