On Friday, weather permitting, we will go outside and record our observations of weathering and erosion happening right here at Lone Star! Turn your notebook sideways, and create a t-chart with the left side for "mechanical weathering" and the right for "chemical weathering". When outside, record at least five examples of each type of weathering that you can observe. For mechanical weathering, look for animal actions, plant growth, abrasion, ice wedging, and pressure release. For chemical weathering, look for animal/plant actions, oxidation (rust), CO2 reactions, water reactions, and acid rain.
If you need to make up this assignment, you can do it at home or any location where weathering and erosion occur . . . which is everywhere!
Watch the following videos in class on Thursday (or at home) and take notes in your class notebook by finding a total of 10 interesting and important facts about weathering and erosion.
Skim, then read, pages 38-45 in your textbook, and then follow the directions on the worksheet carefully.
Create flash cards for the vocabulary words listed on the attached worksheet. If you do not have index cards to use, you may create a vocabulary list in your notebook instead.
