4th Grade Science Unit 2

Big Idea:

Matter has specific physical properties.

Student Expectations:

Priority TEKS

4.5(A) [Readiness] Measure, compare, and contrast physical properties of matter, including size, mass, volume, states (solid, liquid, and gas), temperature, magnetism, and the ability to sink or float

Focus TEKS

4.5(B) [Supporting] Compare and contrast a variety of mixtures, including solutions

Ongoing TEKS

4.1(A) [Tools to Know] Demonstrate safe practices and the use of safety equipment as described in Texas Education Agency-approved safety standards during classroom and outdoor investigations using safety equipment, including safety goggles or chemical splash goggles, as appropriate, and gloves, as appropriate.

4.2(A) [Tools to Know] Plan and implement descriptive investigations, including asking well-defined questions, making inferences, and selecting and using appropriate equipment or technology to answer his/her questions

4.2(B) [Ways to Show] Collect and record data by observing and measuring, using the metric system, and using descriptive words and numerals such as labeled drawings, writing, and concept maps

4.2(F) [Ways to Show] Communicate valid oral and written results supported by data

4.3(A) [Ways to Show] Analyze, evaluate, and critique scientific explanations by using evidence, logical reasoning, and experimental and observational testing

4.4(A) [Tools to Know] Collect, record, and analyze information using tools, including calculators, microscopes, cameras, computers, hand lenses, metric rulers, Celsius thermometers, spring scales, balances, graduated cylinders, beakers, hot plates, meter sticks, magnets, collecting nets, and notebooks; timing devices; and materials to support observations of habitats of organisms such as terrariums and aquariums

Student Learning Targets:

• I will measure size, mass, volume, and temperature of various objects.
• I will observe and identify the states of matter, the ability to sink or float and the magnetism of various objects.
• I will write to explain the changes that can occur with water when heated or cooled.
• I will compare and contrast physical properties of different types of matter.
• I will compare and contrast a variety of mixtures and solutions.

Essential Questions:

• How can you differentiate between a mixture and solution?
• What can you learn about an object by identifying and measuring its physical properties?
• What changes can occur when a physical property is altered?
