Homework!!

Homework was to complete the crossword puzzle for the periodic table and if you did not finish the chemical formula for the ionic compounds.

Have a great night!

Homework Review

READ paging 131 and 132 and complete the ionic problems that was given in class

Not hard

Ionic bonding

Todays lesson is about ionic bonding

Engage/Explore:

Explain:

Please click on the link below (choose "bonding part 2") the last from the list the same one in class

for additional help use the link below

Elaborate: this is just creating the dot diagram not showing the ions

This is creating the Ion compounds 
there are a few that would need more than one element to complete the electrons needed. (example- Aluminum fluoride aluminum needs 3 fluorides to take all of aluminums electrons [Al]+3 ----> 3[F]-1

 

Evaluate: Write down if it is not ionic bond or the dot diagram FOR ionic compounds

Example:

Periodic Project!

Most of the 8th graders have received an Element they should be working on this weekend. This is due Monday November 21

For those that that missed the directions you can get them again.

The cover of you project should be the card of your element in a specific color. No two students will have the same element.

The cover will complete number 1 and 2 of the list of 7 tasks.

 The cover should look something like this

For the rest of the tasks you can list them or get creative and present a visual picture ( please number it)

For the sheets complete: 

Identify the category-  until 9

Identify the Element- until 10

You will need to complete the constructed response

question: Does the periodic table help determine the properties of the element? How/Why?

Organizing the Elements 3.2

Menedeleev..... he was given credit for creating the first version of the periodic table in 1869

In the table cards he included the atomic mass and the chemical symbol. He organized the elements by Group and periods (rows)

Lets look at a new periodic table.

Click on the table cards to see the information 

and the electron config

how the periodic table is organized

Essential Question:What did medeleev discover?
What information does the periodic table contain?
How is the periodic table useful?

Unit Essential Question/Big Idea:How is the periodic table organized?


What Type of Lesson: (Introductory/Aquisition, Extending Thinking, or Assessment)


Scholar Centered Learning Goal: (Statement of Objective should be posted on the board)Students will read the periodic table in order find information about specific elements in the periodic table



Resources/Materials:

• Chemistry Scavenger Hunt (PDF) handout (PDF)

Instructional Presentation (Please see the instructional presentation sequences per content)

Explain:
1) Distribute the Periodic Table of the Elements essay handout and have students read it. When they have finished, lead a discussion about how it was possible for Mendeleyev to develop a periodic table of elements before atomic structure, the essence of the table, was even known. 

students work in pairs as they explore the Periodic Table of the Elements interactive activity.

Direct students to several sample elements within the interactive and identify the following information specific to each:

• The atomic number refers to the number of protons in the nucleus of the element's atoms. (Gallium, for example, has 31 protons.)
• The atomic mass increases as the atomic number increases, but unevenly. This is because the number of protons does not always equal the number of neutrons. The listed atomic mass is the average mass for all forms, or isotopes, of each element.
• The number of neutrons shown is the number for the most common isotope of the element.
• Electron configuration is the number of electrons found in each energy level of the element's atoms, starting from the innermost, or lowest, energy level.

2) Distribute copies of the Chemistry Scavenger Hunt (PDF) handout and allow 10 minutes for pairs of students to locate the missing information.

 

CFU:What four pieces of infromation are included in each element square of the periodic table? 

What is the atomic number?


Elaborate/ Evaluate:

3) students to work independently to create their own Chemistry Scavenger Hunt. Tthey are to plan the table so that the left column symbols, when placed in order side by side, spell a word. The symbols for francium (Fr), iodine (I), carbon (C), titanium (Ti), oxygen (O), and nitrogen (N), for example, spell the word friction.

• For each element,  students fill in three or four columns, including at least one of the shaded columns.
• students exchange their Chemistry Scavenger Hunts with fellow students and complete them.

Quiz time!!! chapter 3 lesson 1

The atomic Models (names and the person that discover it)
The parts of the Atom!!!

Be prepared (Test Day)

Today is Wednesday!!! Tomorrow is Thursday!!! TEST DAY!!! 

Ok.... I had a day of review planned for Thursday because we were going take the test on Friday. But there was a trip of Friday........

As the week continued I see that 
1) the trip might be cancelled because of scholars that lack self control. so..... we could have test Friday
2) we finished Chapter 2 (we can have the test)

Choices Choices (either way I will have a lesson prepared)

So because we finished the chapter I see no reason not to give the test Tomorrow. 

BE prepared to have a test!!

this is not a quiz but a test. There will be a constructed response piece.

Energy Forms and State of Matter

Focus Question: How does heat affect the state of matter and energy changes?

 Click on the link below to get some helpful hints and tips about the 3 states - solid, liquids and gases. Click on the play video button to begin!

http://studyjams.scholastic.com/studyjams/jams/science/matter/solids-liquids-gases.htm

Activity one

handout for activity one below. It contains the three states of matter and arrows linking them up. 

One the sheet write down examples of solids, liquids and gases in the corner of each of the states of matter. These can be anything; it might be easier to start with some things that are in the room (don’t forget the air!). 

Secondly, fill in the boxes that link the different states of matter with how the state of matter can be changed into the next. Think about ice, water and steam as examples, how do you turn water into steam?

Mini Experiment!

In this experiment we will be investigating the effect of temperature on how fast the molecules are moving in a liquid.

You will need: 

Cold water (kept in the fridge overnight)

Hot water (ask your teacher for this)

Food dye

Method:

1.    Pour 50ml of food dye into the warm water.

2.    Observe how the food dye is combined into the water.

3.    Take a photo of the food dye as it combines with the water.

4.    Pour 50ml of food dye into the cold water.

5.    Observe how the food dye is combined into the water.

6.    Take a photo of the food dye as it combines with the water.

7.    Compare the two incorporations.

Discussion

In small group discuss your results. Discuss and write down why you believe the food dye in the hot water incorporated quickly and evenly while the food dye in the cold water was slower and formed patterns.

Also, discuss what would happen if the hot water was heated to the point of boiling? And the cold put in the freezer? 

Activity Two

Open the handout for activity 2.   (gas liquid, solid)

In each box fill in everything you know about that state of matter. It can be new information from todays lesson, any prior knowledge you have, examples of solids, liquids gases and the observable properties of the three states of matter. 

Activity Three

Click on the below link to access the online simulation.

https://phet.colorado.edu/en/simulation/energy-forms-and-changes 

Experiment with the simulation to explore how heating and cooling affects states of matter and energy changes.

Compete the document while experimenting with the online simulation

Activity Four

Once you have completed the table you are to write a descriptive paragraph summarizing your findings using vocabulary you have learnt. Some words you may use include

matter     liquid   solid   material   combining   energy   bonds   shape

point    boiling   pressure   melting   temperature   volume   heat
