Reflection and Refraction by a Lens (001, 002, 003, 004, 005)(RNDr. Mária Bilišňanská, Phd.)
During the activity, students constructed the image of an object formed by a converging and a diverging lens in GeoGebra. They changed the distance of the object from the converging and diverging lens and observed the properties of the resulting image.
Isothermal Process (001, 002, 003)(RNDr. Mária Bilišňanská, Phd.)
At the start of the activity, a deep-sea fish that could not survive outside a high-pressure environment motivates students to investigate the topic "Isothermal Process". From experience, students probably know that when the volume of a gas/air increases at constant temperature, its pressure decreases, and vice versa. But they are probably not aware of the inverse proportionality, i.e. that the pressure p of an ideal gas decreases/increases by the same factor by which its volume V increases/decreases. By measuring and analyzing the measured results, students have the opportunity to understand this relationship.
