Thursday, November 8th Entry Task

Think back to 4.2……

Draw a diagram of a soil profile. Include and label the following: A horizon, B horizon, C horizon, Include arrows showing nutrients cycling between organisms and soil

Schedule:Soil Horizons Poster

Objective:I can identify how

weathering and organic processes create the layers of the soil profile

Homework: Chemical Weathering Formal Lab Due Tomorrow

Soil Horizon A

Soil Horizon B

Soil Horizon C

Plants and animals break down nutrients that get absorbed down into the layers

Plant roots gather nutrients and bring back up to surface in them

Name_____________________________________ Date_______

Soil Horizons PosterLearning objective: to identify how weathering and organic processes create the

layers of the soil profile.

Activity: to create a poster that:• depicts the three layers of a soil profile• gives numerous facts about each layer of soil including

– it’s location in relation to the other layers– what living organisms live in that layer ( incl. pictures)– what affect the organisms might have on each layer – what the soil contains ( incl. pictures)– how climate and region might affect each layer

Grading:

Horizon A Picture (3 pts) __________Description (3 pts) __________

Horizon B Picture (3 pts) __________Description (3 pts) __________

Horizon C Picture (3 pts) __________Description (3 pts) __________

Attach this half sheet to your poster when you turn it in.

Horizons

• Do this in your notebook before your begin your poster

• You can find information from your textbook in section 4.2 and in the ScienceSaurus books page 191– For each horizon write down information about:

– it’s location in relation to the other layers– what living organisms live in that layer– what affect the organisms might have on each layer – what the soil contains– how climate and region might affect each layer

On a scratch piece of paper…..

• Copy down the chart• Fill it in with information

about 1. how weathering helps

create soil

2. How organic processes help create soil

• Must have at least two examples for each

Weathering Organic processes

What creates the soil profile

Friday, November 9th Entry Task

Answer the following questions using full sentences, IQIA.1.What are the main ingredients of soil?2.How do climate and landforms affect soils characteristics?3.How do the activities of organisms affect the characteristics of soil?4.Describe 4 properties of soil?

Schedule:• Soil Poster
