Cells, Tissues & Organs

ScienceThe Human BodyAges 7–9

Understand that the body is organised in a hierarchy: tiny cells are the building blocks, groups of similar cells form tissues, tissues combine into organs (like the heart or stomach), and organs work together in organ systems (like the circulatory system)

Teaching Table

Set out your lesson

Build the cell–tissue–organ–system hierarchy and explain a cardiac example.

Activity

Can attend to a short explanation and respond orally, by pointing, drawing or writing; check relevant prerequisite understanding rather than assuming age proves readiness.

Policy

Check readiness rather than assuming age or source graph order establishes attainment.

Materials

Prepared passage, diagram materials are available in each step.

Preparation

Open the teaching material first. Keep the adult key and check sheet separate until their named stage. No printing, purchase or external media is required for the supplied adapted text tasks.

Safety

Use the supplied text/schematic indoors. Do not collect, taste, touch or disturb wildlife or unknown materials. Discussion does not require a personal experience.

Optional Observation

Only record a real observation after the activity is actually carried out safely; otherwise mark not carried out.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

partial: Understand that the body is organised in a hierarchy: tiny cells are the building blocks, groups of similar cells form tissues, tissues combine into organs (like the heart or stomach), and organs work together in organ systems (like the circulatory system)
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
partial: State that cells are the smallest building blocks of the body, too small to see without a microscope
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
partial: Describe the hierarchy: cells → tissues → organs → organ systems
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
partial: Give an example: muscle cells form muscle tissue, which forms the heart organ, which is part of the circulatory system
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
partial: Can {{name}} explain that the body is made of tiny cells, and that cells group together to make tissues, which make organs, which make whole systems?
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.

Canonical smallest building blocks is biological organization, not atoms; heart contains more than muscle tissue.

“Can your child explain that the body is made of tiny cells, and that cells group together to make tissues, which make organs, which make whole systems?”
