Abstract
The article contains description of several demonstration experiments connected with application of light scattering (LS) for investigation of optical properties of nanoparticles solutions. The demonstrations are based on the usage of laser pointers with different wavelengths (405, 532, and 650 nm) for observing of light scattering and absorbance by various nanoparticles (silver, gold, sulfur, and cadmium selenide). These experiments were used during short course for secondary school students ("Introduction to Nanotechnology") and applied as hands-on activities in order to introduce students to methods of investigation of nanostructures. The demonstrations (included to the course) were tested during summer-camp school (in 2015 and 2016) and in club in chemistry (2016) for secondary school students (15–17 years old).
