Marina S. Robescu; Daniela Ubiali; Riccardo Semproli; Teodora Bavaro – Journal of Chemical Education, 2024
A laboratory experiment was designed to introduce the practical application of biocatalysis in Bachelor and Master courses in biotechnology and medicinal chemistry, respectively. To this aim, the lipase from "Candida rugosa" was characterized (protein concentration and activity), immobilized on a carrier (by hydrophobic adsorption), and…

Elia Bergamin; Giacomo Fabris; Matteo Neffat; Paola Baron Toaldo; Daniela De Luchi; Renato Bonomi – Journal of Chemical Education, 2023
A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

Giuseppe Prete; Federica Chiappetta; Piefrancesco Riccardi; Rosanna Tucci; Antonio Bruzzese; Claudio Meringolo – International Society for Technology, Education, and Science, 2023
Recent research emphasizes the need for a more sustained interaction of schools with universities and research institutions. For example, informal after-school programs integrated into the school curriculum can provide opportunities for meaningful interaction with researchers in active learning settings. At the physics department of University of…

Corni, Federico; Fuchs, Hans U.; Savino, Giovanni – International Journal of Science Education, 2018
This is a description of the conceptual foundations used for designing a novel learning environment for mechanics implemented as an "Industrial Educational Laboratory"--called Fisica in Moto (FiM)--at the Ducati Foundation in Bologna. In this paper, we will describe the motivation for and design of the conceptual approach to mechanics…

Leonello, Rocco; Savio, Matteo; Toaldo, Paola Baron; Bonomi, Renato – Journal of Chemical Education, 2018
Determination of enzymatic activity is a relevant experiment in teaching chemistry and biochemistry to high school and college students. A method for measuring the kinetic parameters of lactose cleavage by the enzyme lactase is described. This enzyme catalyzes the hydrolysis of lactose to galactose and glucose. The kinetic parameters can be…

Basso, A.; Chiorri, C.; Bracco, F.; Carnasciali, M. M.; Alloisio, M.; Grotti, M. – Chemistry Education Research and Practice, 2018
Improving the interest of high-school students towards chemistry (and science in general) is one of the goals of the Italian Ministry of Education. To this aim, we designed a context-based activity that actively involved students in six different laboratory experiences interconnected by a case study of the murder of Miss Scarlet, from the famous…
