Body Temperature Regulation
CONCEPTUALExplain how the human body detects and responds to environmental changes including temperature, including the role of the skin in temperature regulation (sweating, shivering, vasodilation, vasoconstriction)
Mastery Evidence
- Explains what homeostasis means in the context of body temperature
- Describes at least two mechanisms the body uses to cool down and two to warm up
- Explains why maintaining a constant core body temperature is important for enzyme activity
Assessment Prompt
“If [child] got too hot on a summer day and started sweating, could they explain what the body is doing to cool itself down — and why it's so important to keep body temperature steady?”

Prerequisites1
- Aerobic RespirationsoftAges 12—13
Show full prerequisite tree
- Aerobic Respiration soft
Temperature homeostasis links to enzyme activity in respiration and why stable temperature matters for cell function
- Parts of Plant and Animal Cells hard
Diffusion in and between cells requires knowing about the cell membrane as a selectively permeable boundary
- Cells Under the Microscope hard
Understanding cell components requires first knowing that cells are the fundamental unit of life
- Gas Exchange & Breathing hard
Aerobic respiration uses oxygen obtained through gas exchange — the supply mechanism must be understood first
- Cells to Organ Systems soft
The gas exchange system is an organ system — hierarchy concept provides structural context
- Plant Cells vs Animal Cells hard
The cell-to-organism hierarchy builds on understanding that different cell types exist
- Parts of Plant and Animal Cells hard
Comparing plant and animal cells requires knowing the components found in each
- Cells Under the Microscope hard
Understanding cell components requires first knowing that cells are the fundamental unit of life
- How Diffusion Works hard
Gas exchange at the alveoli is driven by diffusion — the mechanism must be understood first
- Parts of Plant and Animal Cells hard
Diffusion in and between cells requires knowing about the cell membrane as a selectively permeable boundary
- Cells Under the Microscope hard
Understanding cell components requires first knowing that cells are the fundamental unit of life
