Motion Basics

Overview

This is Lesson 1 of 15 in the unit Exploring Systems in Motion. Students will be introduced to motion as a concept, learn to classify common types of motion using everyday examples, and build key vocabulary for the unit.

Learning intentions

• Students will be able to define motion in everyday terms.
• Students will be able to identify and describe examples of motion in daily life.
• Students will be able to distinguish types of motion (such as linear, circular, and repeating/oscillating) using simple observations.
• Students will be able to use science vocabulary accurately in short explanations and discussions.

Success criteria

• I can explain what motion means and give at least two examples from my life.
• I can classify an everyday example as one type of motion and justify my choice.
• I can use key terms (motion, position, distance, speed, trajectory, linear, circular, oscillating) correctly in speaking and writing.
• I can participate in a group discussion and record evidence from observations.

Curriculum links

• Scientific thinking: using evidence and observations to describe and compare physical situations.
• Understanding Earth and space/physical science foundations: recognizing and explaining motion-related changes in objects.
• Skills: communicating ideas using appropriate science vocabulary.
• Inquiry: asking questions, making predictions, and testing ideas through simple classroom activities.

Lesson structure (45 minutes)

1. 0–5 min: Hook + question

• Display 3 short teacher-read scenarios (e.g., skateboard moving, pendulum swinging, merry-go-round turning). Students do a quick “Think–Pair–Share”: “What is changing about the object?”
• Teacher probes misconceptions: “Is an object always moving just because it is near movement?”

2. 5–12 min: Mini-lesson—defining motion

• Teach a student-friendly definition: motion is a change in an object’s position over time.
• Model a sentence frame: “The object is in motion because its position changes as time passes.”
• Introduce core vocabulary with quick gestures and examples (no long definitions): position, distance, speed (qualitative at first), trajectory.

3. 12–20 min: Types of motion sorting (stations)

• In small groups, students rotate through 3 stations with picture cards and simple demonstrations (teacher-led if needed).
• Students sort examples into categories: linear (straight path), circular (around a centre), oscillating (back and forth/repeating).
• Each group records: the type of motion and one justification sentence using evidence (what you notice about the path or repetition).

4. 20–28 min: Class discussion—building vocabulary

• Create a class chart: Motion type → observable features → key vocabulary.
• Use guided questions:
• “What do you notice about the path?”
• “What suggests it repeats?”
• “How would you describe the direction of movement?”
• Students add one new vocabulary word to their notes and practice it with a partner.

5. 28–37 min: Quick write + evidence

• Individually, students complete a short response:
• Choose one everyday object from the room or outside the window.
• Describe whether it is in motion and identify the type of motion if applicable.
• Include a sentence using “because its position changes over time.”
• Teacher circulates for formative assessment, checking for correct definition and vocabulary use.

6. 37–42 min: Exit ticket

• Exit ticket prompts (choose one if needed):
• “Define motion.”
• “Give an example of circular or oscillating motion and explain why.”
• Students submit on paper or digitally; teacher collects immediately.

7. 42–45 min: Wrap-up + preview

• Summarize: Today we defined motion and classified common types.
• Preview: next lessons will connect motion to measurements and patterns (distance and time, speed as a concept, and how systems affect movement).

Resources

• Picture cards/scenario cards showing examples of linear, circular, and oscillating motion
• Simple demo items (e.g., ball rolling down a ramp, toy car on a straight track, a string-and-weight pendulum, a small spinner or rotating toy)
• Motion vocabulary cards (position, motion, distance, speed, trajectory, linear, circular, oscillating)
• Sentence frames for ELL support
• Group recording sheet for station sorting (type of motion + justification)
• Student notebooks or science journals
• Timer for station rotations
• Exit ticket slips

Assessment

• Formative: teacher observes station discussions and checks that groups can justify motion types using observable features.
• Formative: quick write checks students’ understanding of the definition of motion and correct use of at least one vocabulary term.
• Diagnostic: exit ticket reveals common misconceptions (e.g., confusing “being moved” with “changing position over time”).

Differentiation

• Support for ESL/ELL:
• Provide sentence frames and word banks during stations and the quick write.
• Allow oral responses or audio recording for the exit ticket if needed.
• Pre-teach vocabulary using gestures/pictures before stations.
• Support for SEN/learning needs:
• Use fewer categories initially (linear vs circular) for students who need it, then extend to oscillating.
• Offer a partially completed class chart for reference.
• Provide visual scaffolds: arrow/path drawings on the sorting cards.
• Extension for advanced learners:
• Ask for an additional feature: “How would you describe the speed qualitatively (fast/slow) based on your observations?”
• Have students create one original example for each motion type and label observable features.
• Flexible grouping:
• Mix students strategically (language strengths, peer support) and assign roles (reader, sorter, recorder, reporter).
