#EscapeCult - The origin of the magnifying glass

Magnifying glass was the first vision-enhancing invention. It was a forerunner of all the wide-ranging observation instruments of Modern Science.

Created in the year 1250, the LUPA is an instrument with the capacity to enlarge the size of images, allowing the visualization of small details. Also called a "magnifying glass", the magnifying glass was the first glasses, as it was used by people who had difficulty seeing.

The magnifying glass is also considered as a simple microscope, which began to assist Science in the expanded observation of its research objects.

Later, the evolution of this invention gave rise to advanced visualization instruments, such as an astronomical telescope, projectors, camera, high-range microscope, telescope, among others.

Studying the theme of the didactic material “Instruments of observation of the stars”, the students of the 5th year of Elementary School, guided by the team of Science teachers and Maker (“do-it-yourself” project, in which significant objects to the studied subject are built in class), created a “homemade magnifying glass”.

In their lives, teachers Silvana, Karina, Flávia and Bruna helped students to use very simple materials, such as PET bottles, quick-drying glue and water, for the construction of magnifying glasses.

Then, they experience for themselves the “mother” effect of the sophisticated instruments of optics and astronomy that exist today.
