Whiteboarding Questions

Covalent Compounds

Today we introduced the idea of covalent bonds and discussed what types of molecules make up covalent compounds and how covalent compounds are named

Classwork

Even more practice with Ionic Compounds

Today, we talked about how Ionic Compounds are named and practiced Lewis Dot Diagrams with them. Students should plan for a quiz on Ionic Bonding and Compounds on Thursday.

The students were also given a review sheet for tomorrow's remediation quiz. Points earned on the remediation quiz will be applied to the Unit 1 test.

Practice with Ionic Compounds

Students were given the day to work on a sheet of ionic compounds and Lewis Dot Diagrams. Attached to the sheets were a set of notes for any student that needs additional support.

Notes

Worksheet 1

Worksheet 2

Ionic Compounds and Lewis Dot Diagrams

Today, we reviewed the number of valence electrons surrounding each element in its neutral state and what type of ion is created most commonly. We then used this information to create Lewis Dot Diagrams for common ionic compounds. In doing so, we discussed conservation of mass.

Classwork

SLO

Today we took our pre-SLO. We will resume regular instruction tomorrow. Students should expect a quiz by the end of tomorrow on valence electrons and ions. 

Valence Electrons day 2

Today, we practiced Lewis dot structures and filled out a table to show the number of valence electrons in each uncharged element. We then related this to the tendency for ions to be present in the world, defining the terms cation and anion. We then previewed the idea of Ionic Bonds.

Valence Electrons

Today, we first went over our test. I attempted to show the students how to answer each question and connect each question to a piece of classwork that we completed earlier. Some of the students that struggled had some misconceptions that we tried to talk through. The information on this test will be covered again on our upcoming test, so students will be able to show their mastery later if they make improvements in the meantime.

In the second half of the class, we covered the Bohr model of the atom and the electron shells that were the basis for chemical understanding before quantum theory gained hold. This is a simplified form of electron formation that should make the fundamentals of chemistry easier to understand for our students while still communicating the most important parts of why chemical reactions occur.

The students finished by completing dot diagrams for a series of atoms to show the number of valence electrons.

Khan academy unit

Ions and Isotopes

Today, we had a short quiz over the periodic table's organization. We then completed our first lab using two pieces of tape. We observed them attracting and repelling other pieces of tape after being pulled off one another. We used this observation to discuss positive and negative charge and the atomic cause of charge. We looked at a few drawn examples of ions and indicated which part of the periodic table is most likely to be the home of positive ions and which part is most likely to show negative ions. Finally, we discussed isotopes and the use of carbon-14 in dating.

Upcoming: Short plickers quiz on Thursday
Test on Friday covering the structure of matter. Study guide available here.

The Periodic Table Lesson 2

classwork

The Periodic Table Lesson 1

Today, the students were told a short version of the life of Dmitri Mendeleev and his journey from poverty and familial isolation to being one of the first to publish the periodic table. We looked into the nature of the table and why it is "periodic." We also distinguished between periods and groups and discussed how groups share chemical properties.

Notes

Atomic Structure

Today, we discussed the makeup of the Universe. Students should now be able to differentiate between the terms molecule, element, and atom. We worked on identifying the atomic mass and atomic number of atoms and reading basic information on a periodic table. Students also received their plickers cards which will be used for basic quizzes at the beginning of classes.
