Working in Physical Science on testing samples and narrowing down what group on the periodic table they belong to (non-metal, metalloid, transition metals, metals, or Noble gases).

While they observed properties like conductivity, magnetism, luster, ductility, malleability, and brittleness, they had to eliminate possible groups and narrow in on the groups it *could* be. Trying to use Dr. Eugenia Etkina’s fall-back, vs. leading questioning. Asking students what they know to help them narrow what they don’t know.
