Card Flick and Newton's First Law

1/31/2019

Today we competed against each other to see who could flick an index card out from under the biggest stack of pennies. We also did an experiment crashing a scooter into some books with various passengers including a dodgeball, basketball, and bowling ball. All of the experiments today demonstrated Newton's first law, the law of inertia. Watch the video to the right to see a recap of our day!

Congratulations on finishing your quiz!

Tomorrow we begin our new unit, Physics! Enjoy the sense of accomplishment that comes with having learned chemistry and get ready for your next adventure!

Quiz Tomorrow

1/29/2019

Tomorrow you will have a quiz over atomic structure, Bohr Models, Lewis Dot Structures for both single atoms and molecules, as well as different types of molecular bonding. Use the previous posts and the videos below to study for your quiz.

More Lewis Dot Diagrams

1/28/2019

Wednesday will be our final assessment for our chemistry unit. It will be over Atomic structure (Protons, Neutrons, Electrons) as well as molecular bonding. An important technique to know is how to make Lewis Dot Diagrams. Watch the video to the right to learn more about these useful molecular models.

Bonding Models and Lewis Dot Sctructures

1/23/2019

In class we learned how to make Lewis Dot Structures along with Bohr Models. Watch the video to the right to learn more about these types of models.

Electron Shells

1/22/2019

Today we talked about why reactions happen in the first place. It all has to do with energy and electrons. Electrons can't go where ever they want in an atom but rather have very specific locations where they can hang out. These places are called levels or shells. Use the video to the right to review how many electrons can fit in each of the different shells.

GOLD TAPE Question: Balance the following equation

Keep on Balancing Equations!

1/17/2019

Tomorrow you have a summative assessment over balancing chemical equations. Use the videos below to help you study.

Balancing Chemical Equations Quiz

1/16/2019

Today in class we took a formative pop quiz over balancing chemical equations. If you missed class or would like to study the answers, the quiz as well as a completed quiz (with answers) are provided below. Balancing chemical equation will be on the unit exam tentatively scheduled for the end of next week.

Balancing Equations Continued

1/14/2019

We continued balancing equations in class today, keeping in mid that we must balance chemical equations to ensure that we uphold the Law of Conservation of Mass. Tomorrow is NWEA testing in the morning.
