Streaming out from the center of the galaxy M87 like a cosmic searchlight is one of nature's most amazing phenomena, a black-hole-powered jet of electrons and other sub-atomic particles traveling at nearly the speed of light. In this Hubble telescope image, the blue jet contrasts with the yellow glow from the combined light of billions of unseen stars and the yellow, point-like clusters of stars that make up this galaxy. Lying at the center of M87, the monstrous black hole has swallowed up…

Have your students practice using their Periodic Tables! Skills build on each other as the decks progress: Deck 1: Locate each element. Locate atomic mass, atomic number, chemical symbol. Practice rounding atomic mass. Deck 2: Locate elements by group and period. Identify the number of shells and number of outer electrons. Deck 3: Locate elements and calculate protons, neutrons, and electrons. Deck 4: Memorize the Chemical Symbols for the first 18 elements.
Periodic Table of Elements War! Great way to Review
Just like the card game war, but instead with the elements on the Periodic Table. After students have learned about the atomic #, atomic mass, protons, electrons, & neutrons this is a great way to review them.I like to play using either the highest atomic number, atomic mass, or you can even use protons, electrons, or neutrons.
