The Endocrine System and Heredity

While the nervous system uses electrical impulses, the endocrine system uses chemical messengers called hormones to regulate behaviour. This topic covers the major glands, such as the pituitary, thyroid, and adrenal glands, and their impact on growth, metabolism, and emotional responses. Students learn how the 'master gland' (pituitary) coordinates with the hypothalamus to maintain the body's internal balance.

Activity 01

Peer Teaching45 min · Small Groups

Peer Teaching: The Gland Experts

Divide the class into groups, each assigned one endocrine gland. They must create a 'fact sheet' and teach the rest of the class about the hormones it produces and how they affect behaviour, using a real-life example like the 'adrenaline rush.'

Think-Pair-Share20 min · Pairs

Think-Pair-Share: Nature vs. Nurture

Students choose a trait they possess (e.g., musical talent or height). They discuss with a partner how much of it they think comes from their parents (genetics) and how much from their upbringing (environment), presenting their reasoning to the class.

Inquiry Circle35 min · Small Groups

Inquiry Circle: Twin Studies

Groups are given summaries of famous twin studies (identical vs. fraternal). They must analyse the data to determine which traits seem to be more influenced by genetics and present their findings on a poster.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • Genes determine exactly who we will become.

    Genes provide a blueprint, but the environment influences how those genes are expressed (epigenetics). Discussion of 'nature via nurture' helps students see that environment can 'turn on' or 'turn off' certain genetic potentials.

  • Hormones only affect physical growth.

    Hormones have a massive impact on emotions and social behaviour, such as Oxytocin's role in bonding. Using case studies of hormonal imbalances helps students see the psychological impact of the endocrine system.
