      TEKS 3.8B: Speed and Mechanical Energy

      • Speed & Mechanical Energy

        About this lesson

        Learning Target: I can explain the factors that impacts speed and apply that knowledge to a scenario.

        Focuses On:

        • The speed of an object is relative to its position and amount of mechanical energy.

        Builds On:

        This is the first time that students are introduced to speed.

        Next Level:

        7.7B:

        distinguish between speed and velocity in linear motion in terms of distance, displacement, and direction


        7.7A:

        calculate average speed using distance and time measurements from investigations

        This lesson is designed to support students' understanding of speed and its relationship to mechanical energy.


        The lesson begins with an introduction to the concept of speed. It explores how an object's speed is interconnected with its mechanical energy and position, and introduces the role that gravity plays in this system.


        This serves as the students' first introduction to the concept of speed as it relates to energy, providing a foundational understanding for future learning in 7th grade.

      Frequently Asked Questions

      How do you teach Speed and Mechanical Energy to 3rd graders?

      To teach Speed and Mechanical Energy to 3rd grade Science students, anchor the concept in a hands-on investigation or real-world phenomenon, then build academic vocabulary and scientific reasoning through guided practice. TEKS 3.8B asks students to plan and conduct investigations that demonstrate how the speed of an object is related to its mechanical energy. Crystal Instruction's free ClearLessons for 3.8B walk through this progression with modeling, guided practice, and built-in checks for understanding, while the ClearSheets provide scaffolded practice. You can download both free on this page.

      What is 3.8B in 3rd grade Science?

      TEKS 3.8B is a 3rd grade Science standard for Speed and Mechanical Energy. It requires students to plan and conduct investigations that demonstrate how the speed of an object is related to its mechanical energy. It is part of the Texas Essential Knowledge and Skills (TEKS) for Grade 3 Science.

      Where can I find free TEKS 3.8B lessons and worksheets?

      You can download free TEKS 3.8B lessons and worksheets directly on this page — no login or account required. Crystal Instruction provides free PDF versions of our Speed and Mechanical Energy ClearLessons and ClearSheets for Grade 3 Science, and each one is also available as an interactive lesson inside the full Crystal Instruction platform.

      What skills are included in 3rd grade Speed and Mechanical Energy?

      TEKS 3.8B (Speed and Mechanical Energy) covers the following 3rd grade Science skills: students learn to plan and conduct investigations that demonstrate how the speed of an object is related to its mechanical energy. Free resources for this standard include Speed & Mechanical Energy.

      Are TEKS 3.8B resources aligned to STAAR?

      Although Grade 3 Science is not directly tested on the Texas STAAR test, TEKS 3.8B builds the foundational skills students need for later STAAR assessments. Every Crystal Instruction ClearSheet for 3.8B is STAAR-aligned, and our ClearLessons are built to STAAR rigor using released STAAR test items, so students practice Speed and Mechanical Energy at the depth STAAR expects.
