Povzetek

Predstavil bom projektno delo pri izbirnem predmetu iz astronomije, v katerem učenci samostojno in povsem varno delajo s projektorjem za opazovanje Sonca v kombinaciji z digitalnim fotoaparatom in računalniškim programom za urejanje slik. Naučijo se tehnike fotografiranja projicirane slike Sonca na zaslon, arhivirajo slike, jih izbirajo in računalniško obdelajo. S slikami ugotovijo in spremljajo lastnosti Sonca: robno zatemnitev, razvoj Sončevih peg, vrtenje (ustvarijo animacijo), vrtilni čas in aktivnost Sonca. Razlika med slikami učencev in slikami profesionalnih observatorijev je neznatna.

Abstract

The paper presents project activities in the optional astronomy subject, in which pupils independently and without any risk work on solar observations using a projector combined with a digital camera and image-editing software. They learn the technique of photographing the projected solar image on the screen, they archive images, collect them and finally process them with the computer. Using the images, they determine and observe characteristics of the Sun: the fringe darkening, the development of sunspots, rotation (they make an animation), rotation time and solar activity. The difference between images made by pupils and images from professional observatories is negligible.
