Perky Description: Patty Proton, like her sisters, is Positive quite large with a huge smile and Favorite Activity: eyes that sparkle (+). Patty is always Hanging out at the Nucleus Arcade happy and has a very positive personality. Nerdy Nelda Neutron Name: is large like Patty, but she has a Nelda Neutron boring, flat mouth and eyes with zero expression (o). Her family is very Description: apathetic and neutral about Neutral everything. Patty, Nelda, and their Favorite Activity: sisters spend all their time at the Hanging out at the Nucleus Arcade arcade. Around the Nucleus Arcade, you will find a series of roadways that are used by another member of the Atoms Family, Enraged Elliott Electron. Elliott races madly around the Arcade on his bright red chrome-plated Harley-Davidson. He rides so fast that no one can be sure where he is at any time. Elliott is much smaller than Patty and Nelda and he is always angry because these bigger relatives will not let him in the Arcade. He has a frown on his face, eyes that are squinted with anger, and a very negative (-) attitude. Name: Elliott Electron Description: Negative Favorite Activity: Racing around the arcade The Atom Part A: How big is an atom? Let’s investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as you can. If you can cut the strip of paper in half 31 times you will end up with a piece of paper the size of an atom! Part A: How big is an atom? What you will do: • Take your strip of paper and cut it into equal halves. • Cut one of the remaining pieces of paper into equal halves. • Continue to cut the strip into equal halves as many times as you can. • Make all cuts parallel to the first one. When the width gets longer than the length, you may cut off the excess, but that does not count as a cut. Part A: How big is an atom? How far did you get? _______ cuts What is that equal to? Cut 1: Child's hand, pockets Cut 2: Fingers, ears, toes Cut 3: Watch, mushroom, eye Cut 4: Keyboard keys, rings, insects Cut 6: Poppy seeds Cut 8: Thread. Congratulations if you’re still in! Cut 10: Still cutting? Most have quit by now!! Cut 12: Microscopic range, human hair Cut 14: Width of paper, microchip components Cut 18: Water purification openings, bacteria Cut 19: Visible light waves Cut 24: Electron microscope range Cut 31: The size of an Atom! Here are some comparisons to think about! Is there anything smaller? • Yes!! The size of an atom nucleus would take about 41 cuts! • Scientists use advanced technology to explore the world of electrons and quarks that are at least 9,000 times smaller than a nucleus. • We can not see anything smaller than an atom with our eyes, even with the electron microscope. Physicists study much smaller things without seeing them directly. Part B: The Smallest Part of Matter You need 3 colored pencils… • Red • Blue • Yellow A.
