Unit One Test Corrections

Worth 10 homework points

For each MC you missed, give me the correct answer and why the answer you chose doesn’t make sense.

Example: 1. C

My answer, B, doesn’t make sense because an ecosystem has to have both living (biotic) and non-living (abiotic) components to function.

Soil Salinization Lab

Soil Salinization is the process of salt becoming concentrated in areas where irrigation is used to make soil fertile.

Why? Irrigation water usually come from underground aquifers, which have a lot of minerals dissolved in them. In areas with a dry climate, the water evaporates, leaving behind salts in high levels.

Soil Salinization Lab- in your lab book

1.

Pre-Lab: compare answers 1-10 with your new group. Then, make a flowchart or some other visual representation of the background info.

What causes soil salinization?

What are the negative effects?

Where does it happen?

Somewhere in your visual representation, also include definitions for: irrigation, minerals, salinization, aquifers, osmotic potential, germinating seeds

3.

You will test 8 salt solutions, varying in concentration between 0-4%, using the directions at the top of page two and bottom of page 3.

Decide on your concentrations and determine how you will make them as a group. Show calculations for all 8 baggies, with units, in your lab book

(can split this work up)

Discuss a procedure as a group and record a quick rough draft of it.

Do it!

Due next time…

Type up a testable question, hypothesis, procedure, and empty data table in a Google

Doc.

Share it with me before class starts!
