Overview

This final lesson brings together learning from the Support and Movement unit. In groups, students classify examples involving animal skeletons, plant support systems and human movement, then present evidence explaining how structures provide support, protection and movement.

Learning intentions

• WALT classify examples of body and plant structures.
• WALT explain how skeletons, muscles and plant structures help living things.
• WALT use observations and evidence to support our ideas.
• WALT communicate a scientific explanation clearly as a group.

Success criteria

• I can sort examples into animal skeletons, plant support systems or human movement.
• I can explain how a structure provides support, protection or movement.
• I can use evidence from a picture, action or observation.
• I can contribute to a clear group presentation.

Curriculum links

• Biological Science — humans and some other animals have internal skeletons and muscles for support, protection and movement.
• Biological Science — investigating how muscles and bones interact during physical activities.
• Biological Science — classifying plants using their structural support systems.
• Biological Science — observing and recording movement to understand how muscles create motion.

Lesson structure (30 minutes)

1. 0–4 min · Recall and hook. Teacher opens the question and recap slides and asks, “How could you prove that a structure helps an organism?” Students briefly discuss examples from the unit, such as a ribcage, a tree trunk or bending an elbow.

2. 4–7 min · Explain the challenge. Teacher places students in five groups of five, displays the three categories—animal skeletons, plant support systems and human movement—and models one example: “A ribcage supports the body and protects important organs.” Students listen, ask clarifying questions and decide which group role they would like: reader, sorter, recorder, evidence finder or presenter.

3. 7–17 min · Group classification and explanation. Teacher gives each group a mixed set of teacher-prepared picture or word cards and the support and movement evidence organiser. Students classify each example, record the structure involved, identify whether it provides support, protection or movement, and write or draw evidence. Include examples such as a bird wing and bones, a dog’s skeleton, a tree trunk, a grass stem, a person bending an arm and a person walking. Teacher circulates, asking, “What is the structure?” and “What evidence shows what it does?”

4. 17–25 min · Group presentations. Teacher uses the presentation prompt slides to keep presentations focused and invites each group to share two examples. Students present using the sentence frame: “We classified ___ as ___. The structure is ___. It helps by ___. Our evidence is ___.” Classmates listen for one accurate use of support, protection or movement and show a quiet thumbs-up when they hear evidence.

5. 25–28 min · Check and correct. Teacher revisits any misconceptions, particularly that muscles pull on bones to create movement and that plants have support structures even though they do not move from place to place. Students revise one statement on their organiser if needed and explain their correction to a partner.

6. 28–30 min · Exit reflection. Teacher asks students to complete the final prompt on the support and movement evidence organiser: “Choose one structure and explain how it helps a living thing.” Students hand in their organisers as they leave.

Resources

• the Support and Movement recap and presentation deck
• the Support and Movement evidence organiser
• Teacher-prepared mixed picture or word cards
• Five group sorting trays or envelopes
• Pencils, crayons and writing boards
• Board or chart paper
• Timer

Assessment

• Listen to group discussions and check whether students correctly classify animal skeletons, plant support structures and human movement examples.
• Question groups during sorting: “What is your evidence?” and “Does this structure support, protect or help movement?”
• Use presentations and the final written explanation to assess whether students can identify a structure and explain its function accurately.

Differentiation

• Provide illustrated cards, a word bank and sentence frames: “The ___ has ___.” “It helps with ___ because ___.” Allow students to draw evidence rather than write full sentences.
• Pair students who need writing support with a confident scribe, while ensuring every student has a speaking, sorting or evidence-finding role.
• Pre-teach or display the words skeleton, bone, muscle, joint, support, protect, movement, trunk and stem; pronounce and gesture each term for multilingual learners.
• Extend confident students by asking them to explain how two structures work together, such as muscles and bones, or to compare a woody tree trunk with a grass stem.
