Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal.
Science lab experiments demonstrate what happens visibly and at a molecular level with the Group 1 highly reactive metals and the Group 17 highly reactive halogens from the periodic table. Experiments also illustrate the range of reactivity among metals. Video has three 5-minute segments for convenience.

Students design and build magnetic-field detectors and use them to find hidden magnets in this activity from "Design Squad Nation." They also learn how NASA uses magnetometers to learn what is going on inside a planet or moon. As they build their magnetic detectors, they use the engineering design process, apply a variety of science concepts, and learn how a planet's or moon's magnetic field gives NASA scientists insights into its structure. Part of the "Design Squad Nation" series.
Cadmium is a chemical element with the symbol Cd and atomic number 48. It is a soft, silvery-white metal.
