1. oneone GTE-3 Objective: To identify the particles within an atom in order to create a diagram of an atom Energy Note: What are atoms made of? Drill: 1. Get a ditto from the SET. 2. Take out your AGENDA.

2. oneone GTE-3 Activity 1: How Small is an Atom? 1.Take your piece of aluminum foil. 2.Fold it in half. 3.Tear along the fold. 4.Repeat steps 2 and 3 10 more times. 5.Think…What will happen if you keep doing this?

3. oneone GTE-3 ATOMS The building blocks of all matter. The smallest amount of any element that maintains the properties of that element.

4. oneone GTE-3 Activity 2: A Question to Ponder… Everything in the universe is made up of atoms. There are gold atoms, oxygen atoms, mercury atoms, etc. How many different types of atoms do you think are in existence (as far as we know)? 118 – Periodic Table

5. oneone GTE-3 Activity 3: Let’s Explore the Atom. BRAIN POP Take notes

6. oneone GTE-3 Objective: To identify the particles within an atom in order to create a diagram of an atom Energy Note: What are atoms made of? Drill: 1. Take out you “atoms” ditto. 2. Get a ditto from the SET. 3. Read the information to yourself. 4. Write any questions that you have in the margins.

7. oneone GTE-3 Read the article, “The Atom.” Complete the table on your worksheet based on your reading. Subatomic Particle : a smaller particle found within the atom

8. oneone GTE-3 PROTON Positive charge Found in the nucleus (center of the atom) 2,000 times the mass of an electron much larger than electrons

9. oneone GTE-3 ELECTRON Negative charge Found outside the nucleus (in the electron cloud) Smallest and least massive particle Travel near the speed of light Are able to escape the atom Their movement creates electricity.

10. oneone GTE-3 NEUTRON No Charge – electrically neutral Found in the nucleus (center of the atom) 2,000 times the mass of an electron much larger than electrons

11. oneone GTE-3 Draw a diagram of an atom. Include 3 protons, 3 electrons, and 4 neutrons. Create a key for your symbols if necessary.
