Science Lesson Plan II: Water Quality Remediation

Science Lesson Plan II: Water Quality Remediation

Related Standards:

NCSCOS (http://www.ncpublicschools.org/curriculum/science/scos/2004/21grade8): In Grade 8, Competency Goal 3 states, “The learner will conduct investigations and utilize appropriate technologies and information systems to build an understanding of the hydrosphere”.

Objective 3.05 Analyze hydrospheric data over time to predict the health of a water system including:

· Temperature, Dissolved Oxygen, pH, Nitrates, Turbidity, Bio-indicators

Objective 3.08 Recognize that the good health of environments and organisms requires:

· Monitoring of the hydrosphere, Water quality standards, Methods of water treatment, Maintaining safe water quality, Stewardship

Goals and objectives:

· Given a scenario of sickness from chemical exposure, students will use their knowledge of exposure, potency, dose, and individual susceptibility to identify the chemical responsible for the sickness.

· Given a scenario of chemical exposure, students will identify possible means to eliminate the exposure from reoccurring.

Essential Question:

What factors are used to determine water quality?

Special Considerations:

For students with Learning Disability/ADHD/Autism:

• Cooperative learning will allow students peer interaction.

Prerequisite Knowledge:

Student lab summaries from last week demonstrated insufficient understanding of water quality characteristics, remediation is needed.

Materials:

Student labs from last week, water quality data collected from field trip

Pre-lesson Activities:

Students copy class objectives

1) Water quality table

2) Analyze pond and stream data from field trip

3) Water Assessment Lab rewrite

4) Poor water quality diagram and paragraph

Homework: Complete water quality diagram and paragraph

Remediation:

Remediate knowledge of water quality:

1) Make sure students have water quality table from last week

2) Class discussion: What are the 6 main characteristics of water quality? Make sure students write them down in their tables.

3) Students work in groups to complete the water quality table to the best of their knowledge.

4) Class discussion: Check and correct water quality table.

Remediate water quality lab:

Return water assessment labs to students and review 1-4 listed below. Students will work in groups of two to complete the assignment and determine which had the best water quality.

1. D.O.

2. How to score data

3. What is required in their paragraph

4. What is required regarding their bioindicators

Expansion:

Whole class discussion:

1) Use the table to analyze the Pond and Stream Data we took on the field trip on Friday and determine whether the water sources were good or poor quality.

2) Copy the data from the lab sheet tallies and use the information to determine water quality.

Evaluation:

Students will sketch and label a diagram and write a paragraph of poor water quality. Due Tuesday
