Chemical weathering lab simulating the process of carbonic acid and the weathering of limestone bedrock. Easy for all to do and fun. 2 day lab – one day for data, one day or graphing and conclusion questions. Great for grades 5-9 in general science, physical science, and/or earth science.
Content emphasis is on chemical weathering - focused specifically on the process of carbonic acid and the weathering of limestone bedrock (how caves and sinkholes are created).
This is an engaging and dynamic lab that kids love to do incorporating arithmetic and chemistry in combination with the scientific method.
Students receive background information on how rocks weather diving into the details of chemical weathering and the specific processes carbonic acid.
Materials are required: primary materials include beakers, thermometers, and effervescent tablets.
Very special cut and paste, Smartboard, or Velcro and laminate activity that challenges many learners based on how the information is presented. The instructor decides the difficulty!
This works well for any level but is GREAT for special education students or college prep learners that need an alternative assessment and may not be great at traditional labs.
Also, perfect for homeschooling!
WIDE RANGE OF ABILITY LEVELS! The application to a diverse body of learners, whether it be age or ability level, is predicated on the fact that the instructor determines the difficulty level of the whole activity or part of the activity based on what information is given and what information is not as well as how verbal questions are presented to the student(s).
This has been used as a pre-class, lab/activity, study guide, review, and assessment. This is an effective teaching tool one on one, in small groups, and as a class when using a Smart Board/Promethean Board/Projection.
A guaranteed hit all around!
A great addition to your geology and chemistry teaching library.
Cut and paste or Velcro and laminate for special education applications and alternative assessments.
Within the classroom, this activity has been consistently very successful and acclaimed by students in grades 5th – 9th within multiple types of schools - public, private, and charter.
This work has also been shared at workshops, in-services, and conferences.
Great feedback from parents, teachers, and administrators.
Even used by teachers in New York State as a preparation for the Earth Science Grade 9 Regents Exam.
