Texas TEKS 2.5

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

• 2.5.A

  identify and use patterns to describe phenomena or design solutions

• 2.5.B

  investigate and predict cause-and-effect relationships in science

• 2.5.C

  measure and describe the properties of objects in terms of size and quantity

• 2.5.D

  examine the parts of a whole to define or model a system

• 2.5.E

  identify forms of energy and properties of matter

• 2.5.F

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

• 2.5.G

  describe how factors or conditions can cause objects, organisms, and systems to either change or stay the same.

01

What Students Need to Do

Students spot patterns and use them to explain observations, make predictions, and improve simple designs. They measure properties, identify matter and energy, and explain how parts work together in a system. They connect causes, structures, and changing conditions to what happens or stays the same.

02

What Mastery Looks Like

Given a simple setup, a student records measurements, finds a pattern, and predicts what will happen when one condition changes. The student names a system's parts and purpose, then links a structure to its job. The student identifies the matter, energy, cause, effect, and any change.

03

Common Misconceptions

Students may call any group a pattern or assume that two events happening together proves cause and effect. They may list system parts without explaining how those parts work together. They may confuse energy with matter, omit measurement units, or assume all changes are permanent.

04

How to Assess It

Give this exit ticket: “A toy car rolls 20 cm from a low ramp, 40 cm from a medium ramp, and 60 cm from a high ramp. State the pattern, predict the next distance, and explain the cause.”

1. 01

   Build foil boats, add pennies one at a time, record capacity, then change the shape to improve the design.

2. 02

   Write: How does moving a cup of ice from shade to sunlight change it, and what causes the change?

3. 03

   Play System Match by pairing picture cards of parts, wholes, and jobs, such as wheel, bicycle, and movement.

4. 04

   Inspect a classroom fan, identify its matter and energy, and explain how blade shape helps move air.
