DO NOW Date: 9/5 Do Now: Pick up Homework and Do Now Review the periodic table that you picked up and list three elements (full name) and their atomic numbers.

-Identify atoms as the building blocks of matter. What are we doing today? ESSENTIAL QUESTION: What are the building blocks of matter? OBJECTIVES: -Identify atoms as the building blocks of matter. -Label the parts of an atom

Tape the periodic table onto the inside BACK cover of your interactive notebook

Research an element Work with your shoulder partner Find an element that has one letter from each of your names in it Ex: Sally and Joe could choose Silicon (“S” from Sally, “O” from Joe) Use your own devices to research Find at least three facts about your element Be prepared to share

Atom Model Comparative Investigation Directions: Look at the two atom models at your table: Record your observations in your INB: SIMILARITIES DIFFERENCES

What are ATOMS?

What are atoms? What are the building blocks of all matter? Atoms

Subatomic Particles

Check for Understanding 1)How many protons does carbon have?

Check for Understanding How many electrons does helium have?

-Identify atoms as the building blocks of matter. What did we do today? ESSENTIAL QUESTION: What are the building blocks of matter? OBJECTIVES: -Identify atoms as the building blocks of matter. -Label the parts of an atom

Using complete sentences, explain atoms in your own words. Date: Sept. 6 and 7th DO NOW Using complete sentences, explain atoms in your own words. Be prepared to share.

What are we doing today? ESSENTIAL QUESTION: How are the atoms of each element different? OBJECTIVES: Use the periodic table as a resource to identify elements and their properties.

Periodic Table and Atoms Using the ATOM model in your INB: INFER what the numbers on this tile mean and record your inferences on your white board.

DRAW and LABEL the tile in your INB, under your Helium Atom Model, p 2 He 4.0026 # of protons = electrons

White Board Practice How many protons are in nitrogen? How many electrons? How many neutrons?

White Board Practice How many protons does Hydrogen have? What is the atomic mass of Hydrogen? How many neutrons does it have?

White Board Practice Find the element that has 10 protons and 10 electrons. Write the symbol on your white board. How many neutrons does it have?

White Board Practice What is the atomic number of Potassium? How many protons does it have? How many neutrons? How many electrons?

Create Your Own Atom Create a key for each part of the atom. Draw the correct number of protons, neutrons, and electrons on the model Use your periodic table to DISCOVER your element. Write it on the back. We will use this later in class. Protons – Neutrons- Electrons-

Protons, Neutrons, Electrons Fill out the Protons, Neutrons, Electrons WS You may use your notes
