<p>Resourced lesson that guides students through a heart dissection.</p>

<p>Resourced lesson that allows students to learn the effect that smoking, asthma and exercise has on the lungs.</p>

<p>Resourced lesson that provides revision opportunities on the topic of gas exchange at the lungs.</p>

<p>Resourced and differentiated lesson that teaches the mechanism of breathing, the relationship between pressure and volume and compares the composition of inhaled and exhaled air.</p>

<p>Resources lesson that investigates the rate of blood flow through model blood vessels. This lesson loosely follows the scientific method as much as possible.</p>

<p>Resourced and differentiated lesson where students learn the organs of te circulatory system, then gain a more detailed understanding of the blood vessels- full detail of the heart is learnt next lesson and full lung detail has been learnt in previous lessons.</p>

<p>Resourced and differentiated lesson that teaches gas exchange at the alveoli.</p>

<p>Resourced lesson that guides students through an investigation into the aerobic respiration of yeast, using methylene blue.</p>

<p>Resourced and differentiated lesson that explains the process of aerobic respiration.</p>

<p>Resourced lesson that allows students to learn the structure of the heart and the function of the different areas. This also stretches students to explain the term double circulation.</p>

<p>Resourced lesson begins by comparing anaerobic respiration in animals and microorganisms, then investigates anaerobic respiration in yeast and explains the value of fermentation.</p>

<p>This resourced and differentiated lesson focuses on anaerobic respiration in animals and encourages comparison with aerobic respiration.</p>

<p>Resourced and differentiated lesson that teaches the structure and function of the organs in the respiratory system, then focuses on surface area to volume ratio calculations.</p>
