TITLE : Unit 03: Investigating Force and Motion SUGGESTED DURATION : 11 days

Unit Overview

Introduction

This unit bundles Student Expectations that address force and motion. Applying a force causes a change in the position and motion of objects.

 

Prior to this Unit

  • Kindergarten
    • K.6B – Explore interactions between magnets and various materials.
    • K.6C – Observe and describe the location of an object in relation to another such as above, below, behind, in front of, and beside.
    • K.6D – Observe and describe the ways that objects can move such as in a straight line, zigzag, up and down, back and forth, round and round, and fast and slow.
  • Grade 1
    • 1.6B – Predict and describe how a magnet can be used to push or pull an object.
    • 1.6C – Demonstrate and record the ways that objects can move such as in a straight line, zig zag, up and down, back and forth, round and round, and fast and slow.
  • Grade 2
    • 2.6B – Observe and identify how magnets are used in everyday life.
    • 2.6C – Trace and compare patterns of movement of objects such as sliding, rolling, and spinning over time.

 

During this Unit

Students demonstrate safe practices as outlined in the Texas Education Agency-approved safety standards while engaging in descriptive investigations to explore how forces can change the position and motion of an object, including pushes, pulls, magnetism, and gravity. Additionally, students communicate and discuss their observations and record data in their notebooks. Furthermore, students consider environmentally appropriate and responsible practices with resources during investigations.

 

Streamlining Note

TEKS 3.6B removed pulleys and work. See the Science TEKS Streamlining Side by Side Grade 3 (link in System Resources below).

 

After this Unit

In Grade 4, students will design a descriptive investigation to explore the effects of force on an object.

 

Additional Notes

STAAR Note

The Grade 5 Science STAAR will directly assess Student Expectations in the following Reporting Categories:

  • Reporting Category 2: Force, Motion, and Energy
    • 3.6B – Supporting Standard
    • 5.6D – Supporting Standard

 

Research

“Students should continue describing motion. And they can be more experimental and more quantitative as their measurement skills sharpen…They also can work out for themselves some of the general relationships between force and change of motion and internalize the notion of force as a push or pull of one thing on another—whether rubber bands, magnets…”

 

“By the end of 5th grade, students should know that:

  • Changes in speed or direction of motion are caused by forces. 4F/E1a
  • The greater the force is, the greater the change in motion will be. The more massive an object is, the less effect a given force will have. 4F/E1bc
  • How fast things move differs greatly. Some things are so slow that their journey takes a long time; others move too fast for people to even see them.” 4F/E2

The main notion to convey here is that forces can act at a distance. Students should carry out investigations to become familiar with the pushes and pulls of magnets. The term gravity may interfere with students' understanding because it often is used as an empty label for the common (and ancient) notion of "natural motion" toward the earth. The important point is that the earth pulls on objects.

 

“By the end of 5th grade, students should know that:

  • The earth's gravity pulls any object on or near the earth toward it without touching it. 4G/E1*
  • Without touching them, a magnet pulls on all things made of iron and either pushes or pulls on other magnets.” 4G/E2

Scientists investigate the natural world in order to understand and explain its systems.

  • Why is it important to know and understand how the natural world works?
  • How are the components (parts), processes, and patterns of systems connected?

 

Scientific investigation is an orderly process to ensure that scientific claims are trustworthy.

  • Why is it important to be able to trust scientists’ work?
  • How do scientists make and support their claims?
  • What processes help scientists investigate their claim?

 

Data is collected and organized in an orderly manner, and analyzed by observing patterns and relationships in order to develop reasonable explanations and make predictions.

  • What are some ways data can be organized?
  • How can data be used to make reasonable explanations?

 

Scientists analyze, assess, and review each other’s work using processes of scientific investigations, and build on one another’s ideas through new investigations.

  • How can we know what to believe about a scientific claim?
  • Why is it important to know and understand how things work and why things happen?

MISCONCEPTIONS / UNDERDEVELOPED CONCEPTS

Misconceptions:

  • Students may think objects only move when an organism applies force, rather than a variety of forces affecting the motion of objects.

 

Underdeveloped Concepts:

  • Students may think the location of an object can be described by stating its distance from a given point, ignoring direction.
  • Students may think that if an object is at rest, no forces are acting on the object, rather than that the Earth’s gravitational pull is exerting a force on the (still) object.

The English Language Proficiency Standards (ELPS), as required by 19 Texas Administrative Code, Chapter 74, Subchapter A, §74.4, outline English language proficiency level descriptors and student expectations for English language learners (ELLs). School districts are required to implement ELPS as an integral part of each subject in the required curriculum.

School districts shall provide instruction in the knowledge and skills of the foundation and enrichment curriculum in a manner that is linguistically accommodated commensurate with the student’s levels of English language proficiency to ensure that the student learns the knowledge and skills in the required curriculum.


School districts shall provide content-based instruction including the cross-curricular second language acquisition essential knowledge and skills in subsection (c) of the ELPS in a manner that is linguistically accommodated to help the student acquire English language proficiency.

ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in reading. In order for the ELL to meet grade-level learning expectations across the foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. For Kindergarten and Grade 1, certain of these student expectations apply to text read aloud for students not yet at the stage of decoding written text. The student is expected to:

ELPS.c.5 The ELL writes in a variety of forms with increasing accuracy to effectively address a specific purpose and audience in all content areas. ELLs may be at the beginning, intermediate, advanced, or advanced high stage of English language acquisition in writing. In order for the ELL to meet grade-level learning expectations across foundation and enrichment curriculum, all instruction delivered in English must be linguistically accommodated (communicated, sequenced, and scaffolded) commensurate with the student's level of English language proficiency. For Kindergarten and Grade 1, certain of these student expectations do not apply until the student has reached the stage of generating original written text using a standard writing system.
