Build an Atom

Goal:
Draw conclusions about the role each subatomic particle plays in determining the properties of a substance.

Agenda:
Warmup

Review Games!

Warmup
Create a new journal entry entitled "Subatomic Particle Role." In your journal, answer the following question:
What do we need to know about the subatomic particles in order to find out if our penny is real gold?

Counting Subatomic Particles

Goals: 
Use the periodic table as a model to identify the average number of subatomic particles (protons, neutrons, and electrons) that make up any element.

Atomic Models

Goal:
Cite evidence from theories to construct a model of the atom that includes the mass, charge, and relative location of the subatomic particles.

Socrative Exit Ticket

Warmup
I will pass back your exit tickets from yesterday. Flip them over. On the back draw a particle and formula model for the following:

1. If the penny and zinc turned into gold.
2. If the penny and zinc did not turn into gold. 

Then take the Socrative quiz. 

The Size of Atoms

Watch this video and consider the following questions:

• What do atoms look like?
• How big are atoms?

How Do We Learn About Something So Small?
Play with the simulation below. Knowing that alpha particles are positively charged, what can we infer about the Rutherford Atom?



Models Card Sort

1. Take out all of the pictures of atomic models. Put the pictures of the atomic models in the order you think they were discovered. What criteria did you use to put them in this order.
2. Take out all of the evidence cards. Match the pieces of evidence to the model they support. 
3. Take out all of the claim cards. Match the claims to the evidence.
4. Take a photo.

Socrative Exit Ticket

Teacher's question: How did our understanding of the atom change with new evidence? What did scientists discover?

You Matter!

Goals:
Define and classify what is and isn't matter.
Use models (particle and formula) to categorize forms of matter as atoms, elements, compounds, and mixtures.

Complete the Warmup

Warmup

1. Discuss: What is a model? Why do we use models?
2. On the paper I provided for you, complete box A. Draw a model of what happened to the penny in yesterday's lab. Include labels as necessary. 

Defining Matter & Forms of Matter
Create a new journal entry entitled "Matter." We will review the slides below as a class. Record notes in your journal. We will also take a brief Socrative Quiz as a class and practice with the new quizlet flashcards.

Card Sort
Divide your whiteboard into 4 sections and label them Atom, Element, Compound, and Mixture. Sort the cards into the correct form of matter. Raise your hand and I will check if you are correct.

Complete the Warmup
Complete boxes B, C, and D on the warmup paper from the beginning of class by drawing particle and formula models of what happened to the penny. 

Penny Lab

Goal:Collect evidence to support or refute a scientist’s claim.

Agenda:
Introduction to Alchemy
Setup Procedure and Observations
Do the Penny Lab
Closing Discussion

Introduction to Alchemy

1. Watch this video.
2. Read the article "Local Scientists Turns Copper into Gold."
3. Discuss: What do you PREDICT will happen if Dr. Barron’s claim is true? What evidence will we need to collect as we test his procedure?

Setup Procedures and Observations

1. Create a new entry in your journal entitled "Penny Lab."
2. Create a procedures and observations table in your journal entry. 
3. Read the lab document and copy the procedures into your journal entry. 

Do the Penny Lab
Before we start... let's talk about what makes good observations. Then let's draw a flowgram of what you will be doing in today's lab.

Closing Discussion
In your journal for today, answer the following questions. Then discuss with your elbow partner. 

1. What can we INFER about Dr. Barron’s claim based on our evidence? 
2. Can we support or refute his claim? Why or why not?
3. What else do we need to know?
