Properties of Fluids (Middle and High School curriculum lesson)

This lab explores the properties of water flow. This inquiry-based lab consists of 2 sections: the Guided Lab Activity and the Going Further (research) portion. The guided lab activity, performed on the first day, is designed to help students observe and understand the way fluids interact with a stationary phase for example, chromatography paper. As the students do their guided lab activity, they will be responsible for generating a minimum of three questions related to the lab activity that would require further research.

CDs and DVDs as Diffraction Gratings (High School curriculum lesson)

The objective of this lab is to campare the diffraction behavior of light waves between a CD and DVD. CDs and DVDs contain regularly spaced micrometer sized features which can act like a diffraction grating. Using commercial electronic storage devices like CDs and DVDs as gratings rather than commercially produced plan transmission gratings enhances student interest in the activity and also opens up a discussion on the trend of improving storage capacity with the invention of Blu-ray and layered DVDs.

SI System and Nanoscale Science (Middle School curriculum lesson)

This unit provides activities for students to learn about the metric system of measurement. A connection to the nanoscale is made by having students read the How Stuff Works article –“How Nanotechnology Works” and answer questions about the article. Further connections of size and the nanoscale can be found in the Resources at the end of the unit.

Using Media to Explore Social and Ethical Issues in Nanoscience and Nanotechnologies (High School curriculum lesson)

This lesson introduces students to social and ethical issues related to nanotechnology. The lesson demonstrates possible social issues through case studeies using popular films, books, and news stories. The lesson is intented to stimulate discussion about social and ethical issues related to nanotechnology as well as, in a broader context, the interaction of science and technology with society.

Water Filtration and Purity of Water (Middle and High School curriculum lesson)

This activity—in which students test a local water supply—is designed to be used as an extension to classroom activities related to treating foul water for consumption. This activity should be done after students have been introduced to the concept of nanoscale and before Lesson 2 - Water Filtration and Nanoparticles lab. Students should have a good grasp of how to convert the size of objects to the nanometer scale.
