Systems in Motion Projects

Overview

Students complete a group project that demonstrates a system in motion. They plan, build/produce, test, and present evidence that their system transfers energy and follows cause-and-effect relationships.

Learning intentions

• Students will create a project that models a system in motion using materials, diagrams, or a simple digital simulation.
• Students will describe how forces and energy transfers cause predictable motion within the system.
• Students will use scientific vocabulary to explain how parts of the system interact.
• Students will present and refine their project based on feedback and testing.

Success criteria

• I can identify the system components and explain what interacts with what.
• I can use evidence from testing to explain how forces and energy transfer produce motion.
• I can communicate my model clearly using accurate scientific language.
• I can improve my project after receiving peer or teacher feedback.

Curriculum links

• Forces acting on objects and how they change motion in a system
• Conservation/transfer of energy in interactions within motion systems
• Scientific investigation skills: planning, testing, analyzing evidence, and communicating findings

Lesson structure (45 minutes)

1. 1–5 min: Project launch + success checklist

• Teacher reviews the unit goal for “Exploring Systems in Motion” and shows the class checklist (system parts, inputs/outputs, evidence from testing, clear explanation).
• Students confirm their group roles (builder, materials manager, tester, presenter, recorder).

2. 6–15 min: Final planning and task distribution

• Groups finalize their plan: what they will build or produce, how they will test, and what data/observations they will record during today’s quick test.
• Teacher circulates to check that the system is clear (e.g., moving parts, drivers/inputs, constraints, expected effects).

3. 16–28 min: Build/produce and teacher check-ins

• Groups build models (e.g., pulley/gear ramp systems, balloon/wind propulsion, spring or elastic launcher with a track, domino/relay-style energy transfer) or prepare a simulation/digital model plus a physical demonstration.
• Teacher provides targeted prompts: “What is the input? What is the output? What evidence shows the relationship between them?”

4. 29–34 min: Quick test + evidence capture

• Each group runs a short test cycle and records at least one piece of evidence (time/number of trials, distance moved, direction change, or qualitative observations tied to forces/energy).
• Students revise one element if results do not match their explanation (e.g., adjust alignment, friction, or explanation).

5. 35–42 min: Present and receive feedback

• Groups present for about 2–3 minutes each using: (1) system diagram, (2) how it works, (3) evidence from their test, (4) one improvement they will make.
• Peers complete brief feedback notes using sentence starters to support ESL (e.g., “I understand…”, “My question is…”, “A next step could be…”).

6. 43–45 min: Reflection and closure

• Individually, students write a short reflection: one claim supported by evidence, one new insight, and one next revision.
• Teacher collects reflections and checks group progress for the final submission/presentation.

Resources

• Materials for system models (e.g., ramps, tracks, pulleys, string, rubber bands, gears/toys, balloons, cardboard, tape, markers)
• Stopwatches or phones for timing (teacher-managed use)
• Student science journals or planning sheets
• Feedback sentence starters for peer review
• Safety glasses (if tools/materials require them) and general lab safety reminders
• Visual organizer: “System → Input/Forces → Energy Transfer → Output/Motion → Evidence”
• Access to teacher-provided simple digital simulation options (if school allows) or printed diagram templates

Assessment

• Formative assessment during build/test: teacher observes whether students can clearly identify system parts and explain cause-and-effect relationships.
• Evidence-based explanation check: student reflection and/or final presentation rubric focus on claims supported by observations.
• Communication assessment: teacher listens for use of scientific language (force, energy transfer, motion, interaction, system).

Differentiation

• Support (ESL/ELL): provide sentence frames for planning and presentation, bilingual glossaries where available, and allow students to record evidence with pictures/labels alongside words.
• Support (SEN/learning needs): offer partially completed diagrams and role cards; reduce writing load by allowing short bullet explanations; provide clear step-by-step group process.
• Extension (advanced learners): require an additional variable analysis question (e.g., “How would changing friction affect distance?”) and a refinement plan to improve the model’s accuracy.
• Choice: students can demonstrate learning through model building, poster + demonstration, or a supervised digital simulation paired with a physical “proof” component.
