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!

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.

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.

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.

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.
