Atoms Computer Lab Assignment Static electricity overview: Go to http://www.school-for-champions.com/science/static.htm Read the info, then scroll down to the mini-quiz (3 big questions). Just answer them to yourself. You don’t need to write the answers to these 3 questions. They are just to get you thinking. ☺ Now that you’re all warmed up, write your answers to these questions on notebook paper. Static Electricity 1. What is the difference between electrons and protons? 2. When does a piece of matter have a “charge?” 3. What happens if two objects have the same charge? What happens if two objects have different charges? Can you think of an example of this? Go to http://www.windows.ucar.edu/tour/link=/physical_science/physics/atom_particle/atom.html&ed u=high and read about atoms. Click the link What’s a molecule? and read the information to answer: (Be sure you are reading at the “Advanced” level. Atoms & Molecules 4. How are the atoms in a molecule held together? 5. What are molecules always doing? 6. What causes molecules to move faster? Click on Reactions make and break molecules. After reading the information, click on chemical components in the third paragraph. 7. What information do the rows on the periodic table tell you? Click on Elements in living things, and answer the following questions. 8. List the four most common elements in a cell. 9. Calcium is needed for ______________________. 10.
