Atoms and Elements Protons – positive, tell element identity Neutrons – no charge Electrons – negative GIST Reading: “The sound of atoms: Scientists communicate with matter at its smallest scales” DO NOT WRITE ON CLASS COPIES

Elements and Structure Valence Electrons- Atomic Number- Protons Mass Number- Protons plus Neutrons Draw the Atom YOUR TURN 8 15.99 O

Interpreting Graphs and Data Read any background information given to help Use the key/color coding to tell what is what Look for differences Look for trends Try to explain why you see the given results

The Periodic Table The periodic table has changed over time as new elements have been added to it. Explain the most likely reason scientists update the periodic table. SILENTLY!!! Sort the class in as many ways as you can at once Ie: Age, Gender, Shirt Color, Height, etc. 2. If you could organize your own periodic table for something, show how you would lay it out. 

Trends in the Table 1

Trends in the Table 2 Reactivity Metallic Character Valence Electrons Mass Number Atomic Radius Ionization Energy Electronegativity

Understanding the Periodic Table 3. Why should we organize the elements? 4. What can we learn about the way the world works by looking at the periodic table?

Last Items/ Questions Poster & Final Report Tomorrow Calendar on Class Website outlines when sections due Catch-up! Poster & Final Report Tomorrow Alternate Assignments for those who are too far behind: Due tomorrow Extra Assignments (Kids with Cameras) due tomorrow

Poster Requirements 1. Neat and Organized     2. Includes most of the general elements from their report Title, Question, Purpose, Hypothesis, Results/Graph, Conclusion     3. Graphs and Tables are clear and labeled     4. Title and Identification present

Alternate Assignment Order the scientific method How can you use it in your experiments?/ In your daily life? Why should we always think using it? (Why is it good?) How do you make a project? Put everything in a poster to present with the Science Fair
