Today is the day that students voted to elect the mayor of JA Biztown.  In the interests of student privacy, I will not be posting the name but I will definitely congratulate him/her!

What the students also did was continue to work in their groups on the various tasks that each company has to undergo beforehand (promissory note, payroll, ads, etc.).  So far, they are doing a great job!

In math, the students did multiplication by the area modeling method.  I have a video below that shows how towards the latter part of the lesson.  Or, you can see how by the image below.

For the in-class activity, we played multiplication bingo.

In science, the students took notes on the three types of rocks, the processes involved in their formation, and the rock cycle.

Here are the notes:

• Rocks are classified as metamorphic, igneous or sedimentary, and that these classifications are based on the processes that created the rock.
• Rocks are made up of one or more minerals.
• The rock cycle is the continuous process of rocks changing from one form to another

Magma - molten rock beneath the surface of the Earth.
Lava - molten rock that reaches the surface.
Igneous - rocks that are formed from molten rock near or at volcanoes.

• Lava changes to igneous rock by the processes of cooling and crystallization.
• Igneous and metamorphic rocks form below the surface of the Earth.
• An igneous rock that is black, glassy, and smooth is formed by rapidly cooling lava above the surface.

Sedimentary - rocks that are formed from deposited rock particles (sediments) that are then compacted.
Cementation - the name for sediments being compacted over time, or compressed.

• Sedimentary rocks are much more likely to have layers and contain fossils

Metamorphic - rock that forms as the result of heat and pressure causing a rock to change from one form to another.

• A rock sample will contain minerals.
• An increase of pressure will cause a rock to undergo metamorphosis.
• The layers show the buildup of rock over time. The lower layers are the oldest due to sediment buildup. This is known as the Law of Superposition.

Weathering - the process of rock being broken down into sediment.
Erosion - the process in which wind or water pick up sediment and move it.
Deposition - the process in which sediment is dropped.

• Weathering causes sedimentary rock to form.
• Igneous and sedimentary rocks can be transformed into metamorphic

The notes for the entire unit are found on my Notes and Study Guides page.
