After a little more than a month of almost daily reminders and it being mentioned in the weekly emails, today was the day. Each student was given a set of 5 pencils for his/her own with the expectation that students would now be responsible for bringing pencils to class.
Beginning tomorrow, students will be expected to bring their own pencils to each class and keep track of them. This will help teach them to be responsible and hopefully cut down on the amount of pencils carelessly discarded on the floors each day.
In math, today was more of a focus on problem solving before be go into the relationship between fractions and decimals. That will begin tomorrow and it will conclude the entire unit on fractions that began back in January.
In science, the students took the following notes for the second part of the Earth History unit:
Weathering – the process of breaking down rock by wind or water (mechanical) or by acids and oxygen (chemical) . A plant’s roots can also break down rock by expanding existing cracks.
Sediment – tiny particles of rock or soil
Erosion – the process in which sediment it picked up by wind or water
*Older mountains are rounder and smoother due to more erosion
*Younger mountains are more jagged due to less erosion
*It took the Colorado River millions of years to erode enough rock and soil to create what is now the Grand Canyon.
*Underground water can erode away soil and rock which can cause sinkholes to form.
Stalactite – an icicle-like structure hanging from the roof of a cave, formed of minerals deposited by dripping water.
Deposition – the process in which sediment is dropped. This can make land more fertile.
Delta – a landform that forms from deposition of sediment carried by a river where the water slows down
Landslide – the usually rapid downward movement of a mass of rock, earth, or artificial fill on a slope
Earthquake – a sudden and violent shaking of the ground
Vibration – a series of small, fast movements back and forth or from side to side
Geologist – a scientist who studies the nonliving things that the Earth is made of, how they form, and how they change
Seismic Wave – a wave of energy that is generated by an earthquake or other vibration
Seismometer – a device used to measure the energy of an earthquake
Volcano – a vent, or opening, in Earth's surface through which molten rock,
gases, and ash erupt.
*Volcanic activity creates new crust (rock) on the Earth’s surface
Crust – the outermost layer of the Earth that is solid
*Some crust is melted back into the mantle while new crust is made by lava from volcanoes
*The amount of Earth’s crust always stays the same
