Internal Body Basics

An introduction to major internal organs like the heart and brain, understanding their basic functions.

• National Curriculum Attainment Targets
• KS1: Science - Animals, including humans

About This Topic

The study of the five senses allows Year 1 pupils to explore how humans perceive and interact with their environment. Students identify which part of the body is associated with each sense: sight (eyes), hearing (ears), touch (hands/skin), smell (nose), and taste (tongue). This topic is a cornerstone of the 'Animals, including humans' strand of the National Curriculum, fostering early skills in observation and data collection.

Understanding the senses is not just about naming them; it is about discovering how they protect us and help us navigate the world. Students learn to describe sensations, such as the texture of a fabric or the pitch of a sound. Students grasp this concept faster through structured discussion and peer explanation during sensory experiments.

Key Questions

1. Compare the function of the heart to the function of the brain.
2. Explain why we cannot see our internal organs.
3. Predict what might happen if our heart stopped working properly.

Learning Objectives

• Identify the heart, brain, lungs, stomach, and intestines as major internal organs.
• Explain the primary function of the heart (pumping blood) and the brain (controlling the body).
• Compare the roles of the heart and the brain in maintaining life.
• Predict the immediate consequences if the heart stops functioning.

Before You Start

Body Parts Identification

Why: Students need to be able to identify external body parts before learning about internal ones.

Basic Needs of Living Things

Why: Understanding that living things need things like air and food provides context for the functions of internal organs.

Key Vocabulary

Heart	An organ that pumps blood around your body, delivering oxygen and nutrients.
Brain	The organ inside your head that controls your thoughts, feelings, and movements.
Lungs	Organs that help you breathe, taking in oxygen and releasing carbon dioxide.
Stomach	An organ that digests food, breaking it down so your body can use it.
Intestines	Long tubes where food is digested further and nutrients are absorbed into the body.

Watch Out for These Misconceptions

Common Misconception

Students often think we only feel things with our fingers.

What to Teach Instead

Explain that the skin covers our whole body and is the organ for touch. Using a 'feather test' on the arm or leg during a peer activity helps students realize touch is everywhere.

Common Misconception

Children may believe that taste and smell are completely separate.

What to Teach Instead

Demonstrate how holding your nose while eating a jelly bean makes it harder to identify the flavor. This hands-on test reveals the connection between the two senses immediately.

Active Learning Ideas

Stations Rotation: The Sensory Circus

Set up five stations: mystery smell jars, sound shakers, feely bags, taste tests, and optical illusions. Groups rotate through each, recording their findings and discussing which sense they relied on most at each stop.

Think-Pair-Share: The Safety Sense

Present scenarios like a smoke alarm ringing or smelling burnt toast. Partners discuss which sense warns them of the danger and what might happen if that sense was not working.

Role Play: The Senses Robot

One student acts as a robot who can only use one sense at a time. Another student must guide them to complete a task, like finding a ball, by only giving inputs for that specific sense.

Real-World Connections

• Doctors, like pediatricians at Great Ormond Street Hospital, use stethoscopes to listen to heartbeats and check lung function to assess a child's health.
• Emergency medical technicians (EMTs) are trained to perform CPR, which manually pumps the heart when it stops beating, to keep blood flowing to the brain until more advanced help arrives.
• Scientists in research labs study the brain to understand how we learn and remember, which can help develop new ways to support children with learning difficulties.

Assessment Ideas

Exit Ticket

Give each student a card with a picture of one internal organ (heart, brain, stomach). Ask them to draw a simple picture of what that organ does and write one word to describe its job.

Quick Check

Hold up a model of the human body or a diagram. Point to the heart and ask: 'What is this organ called and what is its main job?' Repeat for the brain and stomach. Observe student responses for understanding.

Discussion Prompt

Ask students: 'Imagine your heart suddenly stopped working. What do you think would happen to your body right away? Why?' Guide the discussion to focus on the immediate need for blood circulation.

Frequently Asked Questions

Are there more than five senses?

While we traditionally teach the five main senses in Year 1 to meet curriculum targets, humans also have senses for balance (vestibular) and body position (proprioception). You can mention these if students ask how they know where their feet are without looking.

How do I safely conduct a taste test in class?

Always check for allergies and religious dietary requirements first. Use hygienic, disposable applicators and stick to simple flavors like sweet (sugar water), sour (lemon), and salty (saltwater) to avoid choking hazards or strong reactions.

How can I support students with sensory processing needs?

Provide 'opt-out' options for intense smells or sounds. Use visual schedules and allow students to observe others before participating. Active learning should be inclusive, not overwhelming.

What are the best hands-on strategies for teaching the five senses?

Inquiry-based 'mystery boxes' are highly effective. By removing sight, students must use touch or hearing to identify objects. This forced focus on a single sense encourages deeper descriptive language and peer-to-peer debate about the evidence they are gathering.
