Atoms comes from a Greek word that means: _______________________________________________ 3. What are the main parts of the atom? a. ____________________________________ b. ____________________________________ c. ____________________________________ 4. Atoms are mostly ______________________________. 5. Explain how are atoms like letters. _______________________________________________ _______________________________________________ _______________________________________________ _______________________________________________ 6. What makes one atom different than another? _______________________________________________ _______________________________________________ 7. What does the atomic number represent? ______________________________________________ 8. Name 3 types of energy. a. _______________________ b. _______________________ c. _______________________ 9. What are the building blocks of all matter? ______________________________________________ 10.Why is carbon important? ______________________________________________ ______________________________________________ ______________________________________________ 11. Since the periodic table is like the alphabet and we use the letters (atoms) to form words (molecules) lets start with some practice. Make some words out of the symbols from the periodic table. Try to make the longest words you can think of. There is a prize (food) for the longest word and the most words. Examples: He + At = HeAt Ag + U + Ir + Re = Aguirre

Hypothesis: When you add pennies to the can, the buoyant force will ________ because _________. B. Test it out: C. 1. Weight of heavier film can in air: _____ N 2. Weight of heavier film can under water: _____N 3. Buoyant force (subtract!!!) : _____N Compare the buoyant forces (todays vs yesterdays) #8. How does the buoyant force compare to the weight of the displaced water? A) Collect displaced water from displacement tank

B) Weigh it on the scale using NEWTONS!!! 47 Science Notebook Layout DONT COPY UNDERLINED TEXT Mrs. Aguirres Webpage: http://www.quia.com/profiles/caguirre Whats Inside an Atom?

Empty space of gold atom Electrons What does the Hit the Penny model mean? Why did so few alpha particles hit the nucleus? Watch video segment- write 3 notes HYPOTHESIS: Rutherford expected the positively charged alpha particles to pass through the gold atom Why did they bounce off? (2 reasons) Why did so many alpha particles miss the nucleus? Because the atom is mostly. Findings Evidence QuickTime and a TIFF (LZW) decompressor are needed to see this picture.
