Texas TEKS 6.5

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

• 6.5.A

  identify and apply patterns to understand and connect scientific phenomena or to design solutions

• 6.5.B

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

• 6.5.C

  analyze how differences in scale, proportion, or quantity affect a system's structure or performance

• 6.5.D

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

• 6.5.E

  analyze and explain how energy flows and matter cycles through systems and how energy and matter are conserved through a variety of systems

• 6.5.F

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

• 6.5.G

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

01

What Students Need to Do

Students use observations, measurements, and models to explain natural and designed systems. They track materials and energy, connect form to function, and predict how changing one condition affects other parts. They use these connections to explain evidence and improve designs.

02

What Mastery Looks Like

Given an unfamiliar system, students can label its parts, show interactions, and track where materials and energy go. They can use data to explain a pattern, identify a likely cause, and predict how changes in size, amount, or conditions affect performance. Their explanation connects an object's form to its job and cites evidence.

03

Common Misconceptions

Students may treat a repeating pattern as proof that one event caused another. They may think matter is used up, energy cycles like matter, larger always means better, or one part can change without affecting the rest. They may also call any unchanged result stable without identifying the conditions that keep it stable.

04

How to Assess It

Show a sealed terrarium diagram with plants, soil, decomposers, water, and sunlight. Ask students to draw arrows for matter and energy, then predict and explain what changes if light is cut in half.

1. 01

   Build two cup terrariums with equal soil and water, vary light, then diagram parts and predict changes over one week.

2. 02

   Write a claim explaining why a metal spoon heats in soup, using observations to connect structure, energy transfer, and cause.

3. 03

   Sort phenomenon cards into pattern, cause, scale, system, flow, structure, or stability groups, then defend one card that fits two groups.

4. 04

   Map how water and energy move through the school cafeteria, then suggest one change that reduces waste without disrupting the system.
