How the Body Stays in Balance
Explain homeostasis as the process of maintaining a stable internal environment; describe the main feedback loop systems (negative feedback) using blood glucose regulation (insulin/glucagon) and body temperature as concrete examples; and connect the endocrine system (hormone-secreting glands) to the nervous system as two complementary communication systems with different speeds and durations
Lesson
Set out your lesson
“How the Body Stays in Balance means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A simple body outline printout or drawing
- Pencil and labels
Extra for the adult
Worked example. The brain sends signals so muscles know when to move.
Optional challenge. For How the Body Stays in Balance, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples How the Body Stays in Balance, not mastery.

How the Body Stays in Balance means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A simple body outline printout or drawing; Pencil and labels. 1. Say the goal of How the Body Stays in Balance in plain words once. 2. Adult points to one organ or system and names its job in plain words. 3. Child labels three parts and says the job of each. 4. Fresh check: one fresh organ/system job. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Defines homeostasis and explains why maintaining a stable internal environment is essential for survival
- Describes the blood glucose negative feedback loop: glucose rises → pancreas releases insulin → cells take up glucose → glucose falls → insulin release stops
- Compares the nervous system (fast, electrical, short-duration signals) with the endocrine system (slower, chemical, longer-duration signals) and gives an example where each is more appropriate
“If your child ate a large meal of sugary food and was asked what their body does to keep blood sugar from getting dangerously high, could they explain the role of insulin and describe how the feedback system brings levels back to normal?”
