Dear All,
The grade window for 3rd quarter opens on Mon 3/30 and closes on Thurs 4/2. Consequently all missing assignments for third quarter should be turned in by Tuesday 31 to allow time for grading .
Please students check your schoolmax grades and parent follow up with your children to make sure they are not missing any assignments and if they do should turn it in.
Have a great learning week!

Dear All,
The next test of Weathering and soil Formation, Erosion, Deposition will be held on Friday 27th . Given the new vocabulary and concepts in this section students are advised to read/review daily.
A 15% extra credit will be provided on the hard copy to be given in Class.
Good Luck!1

Study guide for weathering erosion Deposition Test
Rocks and Weathering
Key Concepts
- Weathering and erosion work together continuously to wear down and carry away the rocks at Earth’s surface.
- The causes of mechanical weathering include freezing and thawing, release of pressure, plant growth, actions of animals, and abrasion.
- The causes of chemical weathering include the action of water, oxygen, carbon dioxide, living organisms, and acid rain.
- The most important factors that determine the rate at which weathering occurs are the type of rock and the climate
Key Terms
- weathering erosion, uniformitarianism, mechanical weathering, abrasion
- ice wedging, chemical weathering, oxidation
How Soil Forms
Key Concepts
- Soil is a mixture of rock particles, minerals, decayed organic material, water, and air.
- Soil forms as rock is broken down by weathering and mixes with other materials on the surface. Soil is constantly being formed wherever bedrock is exposed.
- Scientists classify the different types of soil into major groups based on climate, plants, and soil composition.
- Some soil organisms make humus, the material that makes soil fertile. Other soil organisms mix the soil and make spaces in it for air and water.
Key Terms
soil, bedrock, humus,fertility, loam,soil horizon, topsoil, subsoil, litter, decomposer
Soil Conservation
Key Concepts
- Soil is one of Earth’s most valuable natural resources because everything that lives on land, including humans, depends directly or indirectly on soil.
- The value of soil is reduced when soil loses its fertility and when topsoil is lost due to erosion.
- Soil can be conserved through contour plowing, conservation plowing, and crop rotation.
Key Terms
- sod , natural resource , Dust Bowl , soil conservation
- contour plowing, conservation plowing , crop rotation
Changing Earth’s Surface
Key Concepts
- Weathering, erosion, and deposition act together in a cycle that wears down and builds up Earth’s surface.
- Gravity causes mass movement, including landslides, mudflows, slump, and creep.
Key Terms
Water Erosion
Key Concepts
- Moving water is the major agent of the erosion that has shaped Earth’s land surface.
- Through erosion, a river creates valleys, water–falls, flood plains, meanders, and oxbow lakes.
- Deposition creates alluvial fans and deltas. It can also add soil to a river’s flood plain.
- Groundwater can cause erosion through a process of chemical weathering.
Key Terms
runoff , rill , gully , stream, tributary, flood plain, meander, oxbow lake, alluvial fan
The Force of Moving Water
Key Concepts
- As gravity pulls water down a slope, the water’s potential energy changes to kinetic energy.
- Most sediment washes or falls into a river as a result of mass movement and runoff.
- A river’s slope, volume of flow, and the shape of its streambed all affect how fast the river flows and how much sediment it can erode.
Key Terms
Glaciers
Key Concepts
- There are two kinds of glaciers—continental glaciers and valley glaciers.
- Glaciers can form only in an area where more snow falls than melts. Once the depth of snow and ice reaches more than 30 to 40 meters, gravity begins to pull the glacier downhill.
- The two processes by which glaciers erode the land are plucking and abrasion.
- When a glacier melts, it deposits the sediment it eroded from the land, creating various landforms.
Key Terms
glacier continental, glacier, ice age, valley glacier, plucking, till, moraine, kettle
Waves
Key Concepts
- The energy in waves comes from wind that blows across the water’s surface.
- Waves shape the coast through erosion by breaking down rock and transporting sand and other sediment.
- Waves shape a coast when they deposit sediment, forming coastal features such as beaches, spits, and barrier beaches.
Key Terms
Wind
Key Concepts
- Wind causes erosion by deflation and abrasion.
- Wind erosion and deposition may form sand dunes and loess deposits.

Hi Everyone!
As you have noticed, my after school tutoring is not going as scheduled due to my involvement in professional development courses since Feb 2015.
That makes it harder to personally assist students who need help. However, the National Honors society is also offering after school tutoring but students need to go to guidance and fill out a tutoring request form so that students can be paired with the appropriate tutor.
As at this time of the year, we expect students to maintain good academic behavior and conduct themselves in a manner that supports learning.
They may not be getting Homework this week through Wed because of the PARCC testing.
I hope you can encourage them to sleep early and so they wake up fresh and ready to give their best.
Have a great learning Week!

Hi Parents and students,
Quick and easy to set up
