3rd Grade Science Unit 2

Big Idea:

Matter has physical properties that can be measured, tested, and recorded.

Student Expectations:

Priority TEKS

3.5(A) [Readiness] Measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float

Focus TEKS

3.2(C) [Ways to Show] Construct maps, graphic organizers, simple tables, charts, and bar graphs using tools and current technology to organize, examine, and evaluate measured data

3.2(D) [Ways to Show] Analyze and interpret patterns in data to construct reasonable explanations based on evidence from investigations

3.5(B) [Supporting] Describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container.

3.5(D) [Supporting] Explore and recognize that a mixture is created when two materials are combined such as gravel and sand or metal and plastic paper clips.

Ongoing TEKS

3.2(A) [Tools to Know] Plan and implement descriptive investigations, including asking and answering questions, making inferences, and selecting and using equipment or technology needed, to solve a specific problem in the natural world.

3.2(B) [Ways to Show] Collect and record data by observing and measuring using the metric system and recognize differences between observed and measured data.

3.2(E) [Tools to Know] Demonstrate that repeated investigations may increase the reliability of results.

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

3.3(C) [Ways to Show] Connect grade-level appropriate science concepts with the history of science, science careers, and contributions of scientists

3.4(A) [Tools to Know] Collect, record, and analyze information using tools, including cameras, computers, hand lenses, metric rulers, Celsius thermometers, wind vanes, rain gauges, pan balances, graduated cylinders, beakers, spring scales, hot plates, meter sticks, magnets, collecting nets, notebooks, and Sun, Earth, and Moon system models; timing devices and materials to support observation of habitats of organisms such as terrariums and aquariums

Student Learning Targets:

• I will measure, test and record physical properties of solids, liquids, and gases.
• I will describe and demonstrate the shapes solids, liquids, and gases form.
• I will write an explanation of how a mixture can be created and separated.

Essential Questions:

• What gives matter its unique qualities?
• What information about the physical properties of matter can be gathered by observation?
• What objects in your daily life are affected by magnetism?
