Week 8: Chemical Bonding and The Law

As we come to the end of our learning on the periodic table, we will now look at the relationship between the elements, chemical bonding, and the Law of Conservation of Matter. We spent the first two days of the previous week discussing the Law of Conservation of Matter, but this week we will get into more of the math behind it. Review these videos in preparation for class this week.

Week 7: The Periodic Table

There is a new hit song on the radio waves now...well...maybe not on your local radio station, but definitely a cool song to listen to if I say so myself.

How cool was that?

So probably by now you have figured out that we are finally going to talk about that big poster on the classroom wall.  Well if that was your thought, you are most certainly correct. We already know the story of Dmitri Mendeleev and how the periodic table came about, but if you need a refresher click here. 

Before we get into the heart of the matter, we will start this week with three discovery learning stations. 

Learning Station 1: The Periodic Table
This learning station is all about figuring out how to organize the missing elements from the periodic table and then hypothesizing about five elements with regard to their chemical properties. Check out this video before class on Monday. 

Learning Station 2: Atomic Structure Models
This learning stations requires that you choose an atom and build it according to the information provided on the periodic table. You will be assigned one element to study at this station. You will want to review your notes on the structure of the atom to help you out on this activity. Please watch this video before class on Monday.

Learning Station 3: The Law of Conservation of Matter
The Law of Conservation of Matter states that in the formation of new substances matter can neither be created nor destroyed.  You will be busy providing evidence to support this law. Be careful though, things can get pretty messy if you don't follow the directions! Here's the last video you need to watch before Monday.

After we have completed the learning stations, we will share our findings as a class. Be prepared to discuss what you've learned, in addition to asking any questions that will help you clear up any areas of confusion. 

Our focus for the remainder of the week will be the periodic table. Are you ready?

Additional resources for this week include:
Hunting the Elements Periodic Table [PDF]
Periodic Table Games
Element Flash Cards
Periodic Table Name Game
Nova's Elemental Quiz
Periodic Table Quiz
Printable Periodic Table Test (Don't do 28-29 and 43-46; answer key available in classroom)

 

Week 5: Hunting the Elements

Okay so far we have talked about ways in which to describe matter

• Physical properties
• Physical changes
• Chemical properties
• Chemical changes
• States of Matter (motion of particles)
• Changes of States
• Pure Substances (elements and compounds)
• Mixtures (homogeneous and heterogeneous)
• Atoms*
• Molecules*

*We will talk about these for another couple of weeks.

After a long weekend and a test (or video productions), it's time to go on a hunt of the elements. We have been talking about the elements for a few days and now it's time to see elements in action. Here is a snapshot of where we are headed this week! No 80s clothes or scratchy footage in this awesome video!




Good luck on Tuesday's test! See YOU in the classroom!
Matter Practice Test

The Periodic Table

Last week we got a small introduction to the organization of the periodic table.  You probably thought that was enough right? Well, you guessed wrong! There is a whole new world that we have yet to discover about these magnificent elements.

This week, we will take an even deeper look at the periodic table through video and activities.  The periodic table is actually pretty amazing!  There is so much meaning behind the information that is provided just based on what is on each element square and where each element is located.  How exactly is the periodic table organized?

The periodic table handout in class is just one way to present the information on the elements.  If you were to conduct an Internet search, you would see a periodic table for organizing a bunch of cool things.  However, we will just focus on the real periodic table. Here are pictures of different period tables here, here, and here. Check them out and tell me what you think. How are they alike? How are they not alike?

So far we've talked about the atomic structure and now we are going to see how the atomic structure plays a role in the organization of the periodic table.  Mendeleev created the very first period table around 1869 and organized it according to the atomic mass of the elements.  However, we will learn that is no longer the case in the organization of the elements.  In wasn't until the earlier 1900s that another scientist realized through his own research that the atomic mass didn't determine the organization of the elements.  Rather, it was the atomic number that dictated the organization.  Upon making a few adjustments to Mendeleev's periodic table the elements were now aligned and scientist noticed that once in groups the elements shared similar properties with one another.

Learning Targets this Week:

• I can explain the different trends on the periodic table.
• I can differentiate between most reactive and least reactive elements.
• I can identify simple bonds between some elements.

Wrapping up Matter Part 1

Last Week: We revisited concepts that students didn't demonstrate an adequate level of mastery.

This Week: We will continue reviewing missed concepts this week and begin the introductory stages of Matter Part II.

Learning Targets this Week:

• I can analyze literature to find the main ideas, similarities, and differences.
• I recognize that the periodic table contains more than 100 elements.
• I can explain  the organization of periodic table of elements.

Ten Study & Test Preparation Tips:
1. Organize the information from lessons, notes, and activities graphically to help yourself understand concepts in a different way.
        *draw pictures or cartoon
        *make graphs or charts
2. Give your notes to your parents and ask them to quiz you.
3. For study groups with your peers and challenge each other to give new examples based on the notes.
4. Watch the videos located here and add new ideas to your notes that you may have missed in class.
5. Download and listen to podcasts from here.
6. Don't just review one or two nights before an assessment. Review every evening for at least 20 minutes.
7. Only memorize facts! For everything else, use the suggestions listed in Tips 1-6.
8. Conduct an internet search on topics you are still unclear about and find more information to support your learning. (You can even add these things to the left side of your notes.)
9. Come to Help Sessions on Wednesdays from 7:45 to 8:15 in the morning.
10. Ask more questions in class! Don't be afraid to raise your hand if something is not clear for you.  My job is to try and answer your questions or direct you to resources that will help you find the answers.

       

Review and the New

Last week, we learned about the differences between atoms and molecules (1a), pure substances and mixtures (1b), and the basics of an element on the periodic table.

This week we will continue learning about the element squares and how to read them.  In fact, I believe some of you might be able to tell your parents what the information this image means.  Okay, so give it a shot!

***UPDATE - I AM REVISING OUR PLANS DUE TO THE NEEDS OF STUDENTS. I HAVE CROSSED OUT ANYTHING THAT IS NO LONGER ON THE SCHEDULE FOR THIS WEEK.***

(c) M. Prince, 2012

We will have a first major test this week, but not without doing a unique type of review.  Instead of a study guide (that's what your notebook is for), students will get the answers to a mock test that an imaginary student completed.  Our student, whose name is Kaleb, prepared for a matter test similar to the one we will take this week.  How well did he do? Only you can determine the answer to that.  Make sure you're in school Tuesday to join in on this exciting review session.

Besides this we will wrap up the week diving into the period table and pruning our literacy skills in science.  By now we should know the importance of reading for information in science as this always adds to the body of knowledge in class.  We will analyze articles to identify the big picture and conduct a comparative analysis about the content.  Bring your critical thinking hats as we venture into another part of physical science education.

Learning Targets this Week:

• I can interpret the information given on an element square.
• I can analyze literature to find the main ideas, similarities, and differences.
• I recognize that the period table contains more than 100 elements. 
• I can explain how the periodic table is organized.

Classroom Videos

Have you seen what we've been learning in class lately? If not, just step on over to my virtual video channel here.

And Here's Where Your Journey Begins

The world is really amazing and to think all that we can see around us is made up of one thing: atoms.  That's right! Over 100 elements--alone or in various combinations--make up everything we use, eat, and even take for granted.  When you go grocery shopping, have you ever taken a look at the nutrition label on the items in your cart?  Perhaps you've wondered about the materials used in a computer chip.  Why does a cold glass of lemonade look like it's sweating on a hot summer day? Maybe the fact that using a neodymium magnet to extract the iron from iron-fortified cereal seems gross, yet pretty cool at the same time! Then again maybe you're wondering how something so much smaller than the sharpened point of a pencil can be responsible for everything around you!

(c) M. Prince 2012

All matter (which has mass and takes up space) is made up of atoms.  Matter falls under four different states of matter and goes though energy processes in order to change from one state to the next.  Just like you and another person are different from one another so are atoms.  Each atom has unique qualities that set it apart from the next one.  Tee properties of each atom help us to identify matter.  For instance, if I asked you to describe  an ear of corn, how would you describe it? What about play doh? What makes an ear of corn and play different from each other?  

When we look at the nature of matter here are some things I want to you think about?

• How has the concept of matter shaped how we see our world and the things around us?
• How can I symbolically or physically represent models of atoms, compounds, particle movement, and the law of conservation of matter to understand the concept better?
• How can I describe the differences of matter according to mass, volume, shape, and particle arrangement?
• How do I know if a mixture is homogeneous or heterogeneous?
• How do I know if a substance is an element or a compound?
• How would I describe the Law of Conservation of Matter?

These are the things I want to you inquire about as we start are new unit on the nature of matter.
