Texas TEKS 2.1

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

• 2.1.A

  ask questions and define problems based on observations or information from text, phenomena, models, or investigations

• 2.1.B

  use scientific practices to plan and conduct simple descriptive investigations and use engineering practices to design solutions to problems

• 2.1.C

  identify, describe, and demonstrate safe practices during classroom and field investigations as outlined in Texas Education Agency-approved safety standards

• 2.1.D

  use tools, including hand lenses, goggles, heat-resistant gloves, trays, cups, bowls, beakers, notebooks, stream tables, soil, sand, gravel, flowering plants, s...

• 2.1.E

  collect observations and measurements as evidence

• 2.1.F

  record and organize data using pictures, numbers, words, symbols, and simple graphs

• 2.1.G

  develop and use models to represent phenomena, objects, and processes or design a prototype for a solution to a problem.

01

What Students Need to Do

Students ask questions from what they observe, then plan a simple test or design a solution. They use tools safely, collect measurements and observations, organize data, and make models or prototypes.

02

What Mastery Looks Like

Students can choose suitable tools, follow safety steps, and explain how their plan answers a question. They record accurate evidence with pictures, words, numbers, or graphs and use it to explain results.

03

Common Misconceptions

Students may ask questions that cannot be tested or change several conditions at once. They may treat guesses as evidence, record only expected results, or choose tools without considering safety.

04

How to Assess It

Show a toy car and ramp. Ask students to write a testable question, name one tool and one safety step, and draw a data table.

1. 01

   In teams, test how ramp height changes a ball’s travel, keep the path clear, measure distances, and graph the results.

2. 02

   Show a wilted plant and ask students to write one question, one possible cause, and one fair test.

3. 03

   Play Tool Match: students draw a task card, choose the safest useful tool, and explain their choice.

4. 04

   Design and build a foil shade for a playground thermometer, then compare temperatures in sunlight and shade.
