Hands-on health & medicine projects covering hygiene, germs, UV, heart rate and healthy habits measured safely. Each one lists the exact materials, the time and cost involved, the variables to control and a data table you can fill in — so it works as a class activity or as a full science fair entry.

Health projects here use safe, indirect measures — UV beads, glow lotion, timers and self-ratings — never anything that puts a person at risk. Read the safety notes first; an adult should supervise anything involving microbes.
A research question and hypothesis, an independent and dependent variable, the variables you hold constant, a materials list with costs, numbered steps, safety guidance and a reproducibility score based on how completely the method is documented.
