Natural Sciences and Technology Grade 6 Term 4: Planet Earth and Beyond Systems for Looking into Space (ppt 1)
Topic 4 Systems for Looking into Space Telescopes [part 1] Natural Sciences and Technology - Grade 6
A Magnifying Glass A magnifying glass can also make faraway things look bigger as well as closer. Natural Sciences and Technology - Grade 6
Galileo Telescope Galileo was a Mathematics professor in Italy at the University of Padua. He was inspired to make a telescope after Hans Lippershey had made one in Holland in 1608. He used his own telescope to look at the planets in the night sky. Natural Sciences and Technology - Grade 6
Galileo Telescope He made notes of all the important things that he saw. Only a small part of the sky could be seen. Natural Sciences and Technology - Grade 6
Galileo Telescope Galileo shows his telescope to some scientists. Natural Sciences and Technology - Grade 6
Galileo Galilei Telescope He made the following planet discoveries: - Saturn has rings. - Venus has phases. - Jupiter has a moon. - The Milky Way which was actually made up of billions of stars. Galileo became blind because he looked directly at the Sun with his telescope. Natural Sciences and Technology - Grade 6
Other telescope facts The Hubble Space Telescope was launched into space over two decades ago. It remained in orbit until 2014. It was then replaced by The James Webb Space Telescope. (see picture) Natural Sciences and Technology - Grade 6
Other telescope facts Glass lenses were used to make the first telescopes. Modern telescopes can detect radio and electromagnetic waves. The word telescope is derived from the Greek words which mean "far" and "to look and see". Isaac Newton invented the reflecting telescope. Natural Sciences and Technology - Grade 6
