Class Response: Making Atoms!

Recently in science class, we had 2 Rutgers University students come and teach us how to figure out what an atom is made up of(electrons, neutrons, protons). We recieved a work sheet, blue and gold marbles and green beads. In the same order, these represent protons, neutrons, and electrons. We also recieved two sizes of plastic spheres representing the atom shell, or the orbit, and the nucleus. On the worksheet, it told us to construct the correct atom by decoding the periodic table. Then we had a quiz, a partner quiz, on the symbols of 22 elements. We recieved 22/20.
