Energy Transfers Lab

Overview

Students classify energy as kinetic or potential and investigate energy transfer in a simple movement-based experiment. They then write a short scientific lab report using a structured template with sentence starters, correct grammar, and domain vocabulary, focusing on potential-to-kinetic energy transformations.

Learning intentions

Students will:

• classify examples of energy as kinetic or potential in everyday situations
• investigate how height (potential energy) affects movement (kinetic energy) in a simple experiment
• use a cause-and-effect investigable question, a reasoned prediction, and record observations/data
• write a scientifically structured lab report (aim, method, results, discussion, conclusion) using sentence starters and a jumbled-report sorting activity

Success criteria

Students can:

• correctly match words to meanings on an energy terms worksheet (potential, kinetic, transfer, transformation)
• explain that raising an object increases potential energy, which can transfer into kinetic energy as it moves
• complete a table of measurements/observations and identify the relationship (pattern) between drop height and movement outcome
• produce a lab report in correct sequence using the template (noting at least one source of error/an assumption)

Curriculum links

• AC9S8U05: classify different types of energy as kinetic or potential and investigate energy transfer and transformations in simple systems
• AC9S8I01: develop investigable questions, reasoned predictions and hypotheses to explore scientific models and identify causal relationships
• AC9S8I05: analyse data and information to describe patterns, trends and relationships and identify anomalies
• AC9S8I08: write and create texts to communicate ideas and findings for a science investigation, using appropriate language and text structure

Lesson structure ({total minutes})

1. 0–8 min · Hook (energy snap). Teacher shows three quick scenarios on the board (e.g., “rollercoaster at the top”, “moving skateboard”, “heated air from a lamp”) and asks: “Which ones are mainly kinetic, which are mainly potential?” Students hold up mini-cards labelled K or P, then share one reason with a partner.

2. 8–18 min · Direct teaching (mini-model). Teacher introduces a simple energy model: height → gravitational potential energy → movement → kinetic energy. Teacher explicitly models key language for the lab report (aim, method, results, discussion) and uses 2–3 sentence starters aloud. Students complete a short “Match word to meaning” worksheet (e.g., potential = stored energy due to position; kinetic = energy of motion; energy transfer = energy moving from one object/system to another; transformation = change from one form to another).

3. 18–28 min · Investigable question + prediction. Teacher provides the investigation context: “How does drop height affect how far a moving object travels after release?” Teacher prompts causal wording: “If…, then… because…”. Students write:

• an investigable question
• a reasoned prediction using sentence starters (Example: “If the height is increased, then the distance travelled will increase because more potential energy is available to transfer into kinetic energy.”)

4. 28–52 min · Simple experiment (no special equipment). Teacher sets up a station with basic materials: metre ruler/tape measure, a small ball/marble (or similar), a clear surface (bench with tape markers), and a paper/worksheet data table. Students work in pairs with roles (measurer/recorder).

• Procedure (teacher-led safety reminder): Mark three heights (e.g., 20 cm, 40 cm, 60 cm). Release the ball from each height (same release method). Measure how far it travels from the start line. Repeat twice per height if time allows.
• Students record distance (cm) and one observation phrase (e.g., “slides farther”, “stops sooner”, “curve slightly”). Teacher circulates to check: accurate units, consistency of release, and correct energy classification in the notes.

5. 52–60 min · Data pattern check. Teacher displays a worked example of a results table and briefly models analysing patterns (not just isolated values). Students complete one sentence: “The pattern in the data shows that as height increases, the distance travelled…” and they identify one possible anomaly/outlier (e.g., one distance differs from the others) and suggest a simple reason (e.g., release inconsistency, surface friction, air resistance).

6. 60–70 min · Lab report writing (jumbled report + structure). Teacher hands out:

• a lab report exemplar (short, students read only)
• a jumbled-report worksheet (sentences/paragraphs mixed)
• a sentence-starter bank and a vocab bank (potential, kinetic, transfer, transformation, distance, height, release, energy). Students sort the jumbled report into the correct order (Aim → Method → Results → Discussion → Conclusion) and then write their own 6–8 sentence lab report using the template and correct grammar supports (e.g., past tense in method/results: “I released…”, “The ball travelled…”). Teacher checks each student has: aim, at least two data references, and one explanation linking potential to kinetic energy.

Resources

• Energy terms word-meaning match worksheet
• Jumbled lab report worksheet (mixed sentences/sections)
• Lab report template with sentence starters and vocab bank
• Energy exemplar paragraph (teacher-provided printout)
• Basic materials: metre ruler or tape measure, small ball/marble, masking tape (start line), scrap paper for notes
• Data table printout (heights, distances, repeats)
• K/P mini-cards or small note cards
• Stopwatch/phone timer (optional for organisation only, not for measuring distance)

Assessment

• Formative checks: correct K/P classification reasons during the hook
• Checklist during experiment: recorded units (cm), consistent release, and at least one observation
• Lab report (short): teacher reviews for structure order, correct use of energy vocabulary, and a clear causal explanation (potential → kinetic)

Differentiation

• Support:
• Sentence starters for the investigable question, prediction, results statement, and conclusion
• Word bank with meanings; encourage students to underline key terms they used correctly
• Provide a partially completed method section (e.g., heights listed, instruction lines)
• Extension:
• Ask students to add an extra test height or suggest how to reduce error (e.g., reduce variation in release point)
• Challenge: identify whether any observed change is a transformation or transfer, and name where it occurs
• EAL/SEN:
• Offer sentence frames with connectors (because, therefore, as a result)
• Allow verbal rehearsal with partner before writing; highlight past-tense verbs (released, measured, recorded)
