This lab is analogous with some nanofabrication processes. This lab will help students understand some of the challenges encountered while making semiconductor chips and waveguides, both of which are found in electronic circuits.
Students will visualize the order of numerical properties of objects from the nanoscale to visible scale using exponents and decimals. Students will make size comparisons of objects. Students will develop an understanding of how small a nanometer is in comparison to common objects. They will also learn about the metric system.
Electro-deposition of Copper on a Filter Template for Growing Nanowires (High School AP and Undergraduate Chemistry curriculum lesson)
This experiment will use an electro-plating process to transfer metal ions in a solution to a template to produce nanowires. In this experiment, an anode (platinum strip) will be used in a solution of copper sulfate. Copper will be plated out onto the pores of a filter at the cathode. Students will discover how nanowires can be created to further understand the reduction-oxidation process, Ohm’s law, and the mechanism of metal electroplating.
By using an EasyBake® oven and a spinning apparatus made of simple, easy-to-find components, middle school students can learn basic science concepts and develop their understanding of wafer fabrication which is an important part of nanotechnology processes and methods.
Silver nanoparticles can take the shape of cubes, spheres, bars, wires, bi-pyramids, beams, plates, and discs depending upon the seed it forms from. Students will learn about the differences in physical properties and behavior at the nanoscale as compared to the same materials at the macroscale. This lesson assists students in working with scale and unit conversion.
Coffee Break with Nanoscience: Film Formation and "Coffee Rings" (Middle/High School curriculum lesson)
This lab will explore the phenomena involved in making thin film coatings. Students will explore the problems that crop up in real- life coating applications, and see how to avoid coffee rings and reduce cracking during the drop-casting deposition of a thin film.
The Effects of Gold and Silver Nanoparticles on Brine Shrimp: A Toxicology Study (High School curriculum lesson)
This lab is designed to help students understand the following: the interdisciplinary fields of science, a practical application of chemistry in the real world, and the need to carefully conduct experiments and evaluate data in a collaborative environment. In this experiment, students will compare the toxicity of different concentrations of nanoparticle suspensions on brine shrimp, along with controls, to perform toxicity assays and data analysis.
This inquiry based lesson leads students through several activities that has them compare and contrast physical properties of superhydrophobic coated materials with uncoated materials. In the process they will learn what constitutes “superhydropobic” and surface tension.
The purpose of the lab is to measure the glucose concentration of several synthetic blood and urine samples to determine which patients have diabetes. Students will also build models based on the conservation of mass to further their understanding of the role of insulin on the concentration of glucose in the blood.
