Texas TEKS 5.5

5.5 is a TEKS knowledge and skills statement. These are the student expectations under it.

• 5.5.A

  identify and use patterns to explain scientific phenomena or to design solutions

• 5.5.B

  identify and investigate cause-and-effect relationships to explain scientific phenomena or analyze problems

• 5.5.C

  use scale, proportion, and quantity to describe, compare, or model different systems

• 5.5.D

  examine and model the parts of a system and their interdependence in the function of the system

• 5.5.E

  investigate how energy flows and matter cycles through systems and how matter is conserved

• 5.5.F

  explain the relationship between the structure and function of objects, organisms, and systems

• 5.5.G

  explain how factors or conditions impact stability and change in objects, organisms, and systems.

01

What Students Need to Do

Students use patterns, measurements, and cause-and-effect evidence to explain observations and solve problems. They model connected parts, track matter and energy, link form to job, and predict change when conditions shift.

02

What Mastery Looks Like

A student can study a system, label its parts, and explain how changing one part affects the others. The student supports a prediction with measurements, observed patterns, or evidence from a model.

03

Common Misconceptions

Students may confuse a repeated pattern with proof that one event caused another. They may think matter disappears, energy and matter are the same, or one system part can change without affecting other parts.

04

How to Assess It

Give students a pond food web and ask them to predict what happens if insects decrease. Have them trace one matter pathway and support their prediction with two links from the diagram.

1. 01

   Connect organism cards with yarn to build a food web, then remove one card and trace the effects through the system.

2. 02

   Show a bird beak and two tools, then ask students to explain how each shape helps it perform a specific job.

3. 03

   Play Pattern Detective by giving teams measurement tables and asking them to state the pattern, predict the next result, and explain why.

4. 04

   Check the classroom thermostat every hour, graph the readings, and explain how sunlight, open doors, or air conditioning affect temperature stability.
