Virial Theorem Lesson
Ninth graders describe how equilibrium can occur as the balance of two effects. They model the stability of elliptical galaxies based on how fast stars within the galaxy are moving.
Curated OER
Color Dots 3
Young scholars make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
Curated OER
Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
