Hands-on science,
by teachers for teachers.
A growing library of the most effective and engaging activities for hands-on science learning — built and curated by a community of experienced educators. Free for every teacher, everywhere.
Earthquake! Where was it?
When a seismologist sees a trace on their seismograph, they know immediately there has been an earthquake. But where? In this activity, students use seismograph traces from real earthquakes and must collaborate with others to determine the location of the epicenter.
Purple Tea Acids and Bases
This activity is a quick introduction to identifying acids and bases using blue butterfly pea flower tea as a pH indicator, drawing particle diagrams, and an introduction to reversible reactions and equilibrium. Blue pea flower tea is in expensive, non-toxic, and easy to use.
Measuring brightness with a grease spot photometer
A piece of white paper stained with oil or grease allows students to compare the intensity of light sources. The device takes seconds to make: just rub a small amount of oil or grease onto a piece of paper. Then place one light source on either side of the paper and observe whether the grease spot looks light or dark.
