What is Health?
Many indicators of health are beyond a teenager's control, but there are many changes they can make in their daily life that can improve their health. Middle schoolers think about their physical, social, and mental health status before...
Curated OER
Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...
