How to make a model of the Heart & Lungs

LEARNING OUTCOME 1: SCIENTIFIC INVESTIGATIONS

The learner will be able to act confidently on curiosity about natural phenomena and to investigate relationships and solve problems in scientific, technological and environmental contexts.

 MATERIALS  NEEDED :

  HOW TO MAKE A MODEL OF THE HEART AND LUNGS: (See photos below)

STEP :

Mix the play dough (see recipe below). 

STEP :

Shape the dough to form the left and right atria as well as the left and right ventricles of the heart. Remember to use the cardboard for a base.

STEP :

Cut the plastic tubing into lengths for the aorta and the pulmonary artery.

STEP :

Insert the tubing for the aorta into the right atrium at the correct place.  

STEP :

Insert the tubing for the pulmonary artery into the left ventricle at the correct place.   

STEP :

Paint the heart and the plastic tubing blue or red (see picture).

 STEP :

Place the sponges on either side of the heart to represent the lungs.  

 STEP :

Place the open ends of the tubing into the lungs at the correct places.  

STEP :

Using the black koki, write the following labels on pieces of paper (6 x 3 cm) and either paste or pin the labels onto the cardboard:

Right Atrium; Left Atrium; Right Ventricle; Left Ventricle; Aorta; Pulmonary Artery; Left lung; Right lung.

PLAY DOUGH RECIPE (MADE OF BREAD SLICES!)

INGREDIENTS:

7 Slices of white bread

7 tsp school glue (white glue, e.g. Ponal)

Half tsp dishwashing liquid

Half tsp Water

INSTRUCTIONS:

1. Cut the bread crusts off and break the bread into small pieces. Place in a mixing bowl.

2. Add the glue and mix well.

3. Add the dishwashing liquid and water, mix well until the paste is smooth (should feel like clay).

4. If mixture is too dry, add a little water.

5. Make your model and allow 24 hours to dry.
