Education Standards
Nanotechnology and Water-Day 4
Overview
The activity for high school students aims to display the importance of water quality and how nanotechnology can be used to help purify the water.
Standards
ES.3.3 Identify and differentiate between renewable and nonrenewable resources present within Earth’s systems. Describe the possible long-term consequences that increased human consumption has placed on natural processes that renew some resources.
ES.4.2 Describe the relationships among evaporation, precipitation, ground water, surface water, and glacial systems in the water cycle. Discuss the effect of human interactions with the water cycle.
Learning Objectives
Students will gain an appreciation for the importance of access to clean water.
Students will explore how osmosis and cell behavior relates to the human body and polluted water.
Students will prove that our cells can transfer dangerous materials through their membranes, similar to the egg in their experiment.
Materials
gloves
goggles
lab aprons
plastic storage containers with egg soaking in polluted water sample
tongs
tray
pencil or pen
measuring tape
caliper
scale
plastic squirt bottle of distilled water
Exacto knife or razor
strainer
small cup
an HMT mercury test kit
test tube holder
paper towels
Other Important Notes
Differentiation /Instructional Strategies:
Using multimedia instructional strategies, students will gain background information and an understanding of what nanotechnology is.
Technology/Science and society will also be addressed by discussing what human behaviors can help or hurt water quality.
How will you differentiate the content, process, and/or product?
Students with varying strengths and weaknesses will be grouped together for the lab.
Assessments:
A final lab report will be handed in at the end of the lab.
