Put one hand where you think your heart is. Now point to where you think your brain is. After lunch, where do you feel the food sitting?

Today we will find out the names of five main organs, where each one sits, and the job each one does.

Point with me, one organ at a time.

Brain — point to your head. Job: the control centre that thinks and tells your body what to do.

Heart — hand on your chest, a little to the left. Job: the pump that moves blood around.

Lungs — both hands on your chest. Job: two soft, spongy organs that fill and empty when you breathe.

Stomach — hand on your upper tummy. Job: the stretchy bag that holds food.

Intestines — hand on your lower tummy. Job: long tubes that finish the food job.

Which organ do you think sits highest in the body?

In your group, you will make a life-size body map, and every one of you places one organ.

1. One volunteer lies still on the paper, arms a little out from their sides. Two of you draw carefully around them with a marker. Then the volunteer stands up.
2. Each of you takes one organ card: brain, heart, lungs, stomach or intestines.
3. Take turns. Put your card where that organ sits in the body, and write its name beside it.
4. After each card, your group checks: do you agree, or would you move it? Read out the organ's job from the card.

Nobody has to be drawn around. If no one in your group wants to be, draw a body shape on the paper instead.

Are the chest organs higher than the tummy organs?

Look at the body on the board. This time the labels are not the names of the organs. They are the jobs the organs do.

Some of you will come up, one at a time, and drag a job onto the organ that does it. Everyone else decides whether you agree, and says why.

Two of these jobs happen in the chest. Two of them are about food, and that is the tricky pair.

On your Investigation Journal page, put the five organs in roughly the right places on the body outline. Label each one: brain, heart, lungs, stomach, intestines (the words are on the board to copy).
