2. Warm Up – November 27th As you come in quietly:
Pick up a warm-up sheet on the counter by the door
Grab your ASSIGNED laptop and log-in
Find the Ted ED video on TED ED website called The Wacky History of the Cell theory and watch it. If you have headphones, use them, if not, use Closed Captioning
Complete the Warm-Up sheet using the video and your ScienceSaurus

3. Atomic Theory

4. Just How small IS an atom?

5. Atomic Theory Timeline
LEFT side
RIGHT side
Write a power paragraph EXPLANING how the Atomic Theory has changed over time. 1. Main Idea/Introduction sentence 2-5 sentences that use evidence to describe details about the main idea 6. Closing sentence that summarizes what you know
Use your workbook (pg. 366), Ted Ed Video and ScienceSaurus (pg. 267) to fill out the Atomic Theory Timeline. Follow the directions on the sheet! When finished, this will go on the right side of your journal.

6. Warm Up – November 29th As you come in quietly:
Pick up a Cell Organelle handout from the counter by the door.
Use the ScienceSaurus and Pick workbook to fill out the FIRST 6 organelles of the Cell Organelle chart (cell membrane, cytosplasm, nucleus, mitochondria, ribosomes, and Smooth and Rough ER)
Glue into the warm-up section of your journal

7. The Atom
Atom: the smallest unit of matter, a nucleus surrounded by an electron cloud.
“atom” is from the Greek word “atomos” which means
“not able to be divided.”

8. E N Subatomic Particles Proton Electron Neutron
What are three subatomic particles of an atom? P E N
Proton
Electron
Neutron

9. Inside the atom
All atoms are made of the same 3 subatomic (smaller than an atom) particles.

10. Inside the atom…

11. Inside the nucleus of an atom

12. Inside the nucleus of an atom

13. Key Questions
If there are both protons and neutrons in the nucleus, why does the nucleus have a positive charge?
Protons are positive, and neutrons are neutral, so they don’t give any charge!

14. Outside the nucleus…

15. The Atom -
Electron
Nucleus +
Neutron
Proton
Electron Cloud

16. + - Key Questions What are the charges of the subatomic particles?
Protons Electrons Neutrons - +

17. How Do You Weigh an Atom?
What units do you use to measure the mass of an atom?
 Atomic Mass Units (AMU)
Atomic Mass Units (AMU)
 1 AMU = Mass of one proton

18. Sizes of Subatomic Particles
How big are protons, electrons, and neutrons compared to each other?
Big
Tiny + -

19. Summary of Key Concepts

20. Summary of Key Concepts
Protons (+) = Electrons (-)
#Neutrons =
Atomic Mass – Atomic Number
Atomic Mass =

a)Electrons and protons are in motion around a nucleus that contains neutrons.
b) Neutrons are in motion around a nucleus that contains protons and electrons.
c) Protons are in motion around a nucleus that contains electrons and neutrons.
d) Electrons are in motion around a nucleus that contains protons and neutrons.

23. Formative Checkpoint
Which of the following correctly describes a property of an atom? A.It has more protons than neutrons. B.It has a negative or positive charge. C.It has an equal number of protons and electrons. D.It has an equal number of neutrons and electrons.

24. Practice Problems
1. How many protons are there in an atom of Sodium (Na)?
2. How many electrons are there in an atom of Sodium (Na)?
3. What is the atomic mass of an atom of Sodium (Na)?
4. How many neutrons are there in an atom of Sodium (Na)?
5. How many protons are there in an atom of Lead (Pb)?
6. How many neutrons are there in an atom of Lead (Pb)?
7. Add the protons and neutrons of Lead together. What number is this?  
8. Draw a diagram for each element below. Be sure to label how many protons, neutrons and electrons there are: 
Draw an atom of Oxygen (O). Label the protons, neutrons, and electrons.
Draw an atom of Helium (He). Label the protons, neutrons, and electrons.
Draw an atom of Carbon (C). Label the protons, neutrons, and electrons.

25. PHET: Build an Atom Investigation
Before you begin, complete the Pre-assessment with your partner. This is part will not be graded 
Open Google and type in “PHET”
Click on “Phet Interactive Simulations”
In the search bar, type “Build an Atom”
A list will appear, Click on “Build an Atom”
Click the WHITE ARROW and download the program.
Click “Run”
Follow the directions on the Sheet!

26. Warm Up – December 1st As you come in quietly:
Open your journal to your Cell Organelle Chart
Use the ScienceSaurus and Pick workbook to fill out the Last 6 organelles of the Cell Organelle chart (Golgi Complex, Cell Wall, Chloroplast, Large Central Vacuole, Lysosome)

27. Show what you know! We Do together! You do independent!
Watch Brain Pop and Study Jams Atoms to review
Use chalk to create atoms on our table tops 
Complete the “Modeling Atoms Investigation” using the periodic table on pg. 265 of ScienceSaurus or pg. 381 in workbook.

28. Consider this picture…
What is shown in this picture (red and white)?
What is represented by the red spheres in the picture?

On the molecular level (very zoomed in), we see the molecules.
These molecules are called atoms.

30. For Tomorrow…
Any material that is made up of one type of atom is called an element
