What’s So Big about Nanotechnology? Activity–Stations Kit
By: The Flinn Staff
From nanofabric to nanobots, nanotechnology has created so much “buzz” that it’s hard to tell where the science ends and the science fiction begins. In this activity-stations lab, students explore some of the fascinating developments in the rapidly growing field of nanotechnol- ogy. Simply set up the four mini-lab activities and allow students to rotate through the stations in any order. Student activities include:
• Placing objects in order of relative size from the astronomical to the atomic level.
• Exploring the properties of a magnetic fluid.
• Simulating a method of using nanoparticles to deliver medicine to
targeted cells.
• Investigating water-repellent sand.
The activity-stations format allows more labs to be completed in less time, with each activity designed to take 10 minutes to complete. This versatile kit fits into many areas of the science curriculum with applica- tions in measurement, physical and chemical properties, the health and biomedical fields, consumer science, and STEM education. Includes Instructor’s Notes with sample data, extensive background information, reproducible student handouts, and all necessary supplies.
Complete for 24 students working in groups of three.
“Golden” Silver Nanoparticles—
Super Value Laboratory Kit
By: The Flinn Staff
Discover the incredible properties of silver nanoparticles in this hands- on nanotechnology activity. Students create their own colloidal silver solution, observe the ability of the solution to scatter light, and learn about its antimicrobial properties. The unique physical and chemi- cal properties of silver nanoparticles and macroscopic silver will be compared and contrasted. Students will see how the silver nanoparticles appear gold rather than silver! Instructor’s Notes, background material, and reproducible student handouts are included.
Super Value Kit is complete for 5 classes of 30 students working in pairs. Flashlight or laser pointer is required and available separately.
Modeling Nanotechnology— Encapsulation by Sodium Alginate—Student Laboratory Kit By: Brett Criswell
Central Columbia H.S., Bloomsburg, PA
Nanotechnology is the study of the preparation and properties of atomic, molecular, or macromolecular particles in the size range of 1–100 nanometers. An exciting new breakthrough in nanotechnology involves the delivery and transport of medicines to treatment areas in the body by encapsulating drugs in molecular “cages” consisting of nanoparticles. In this modern, hands-on lab activity, students will model this technology on a larger scale using sodium alginate, a natural polymer from seaweed. When sodium alginate is added to a solution containing calcium ions, calcium alginate precipitates out as micro- spheres. These “capsules” can be used to trap and also release indicator dye molecules. An engaging modern-chemistry experiment!
Complete for 30 students working in pairs. Reusable 6-well reaction plates are recommended and available separately.
