(02) The Timeline of Life

This week we will continue the discussion of the formation of the universe, solar system, and earth.

Many scientists have come to use the “Big Bang” theory to explore the creation of the universe – There was nothing and suddenly there was something. Scientists followed theories down various paths by using telescopes to observe the universe.  In the past, some theories have been modified or surpassed by other theories.  Some scientific theories have been disproved.  This is a very important characteristic of science.

Please choose three work cards to research.  Unlike work cards that you have used prior, these work cards only provide you with the topic and some helpful research sites. You must include at least one book in your research. You will need to spend no more than 15 minutes researching the topic and write a minimum of one paragraph about the topic.

Work Cards


Work Card 1:  Telescopes and the theories that early astronomers had.

Research who created the first telescopes.  Discuss in a paragraph the earliest scientists who used telescopes and their theories about the Universe.

Helpful web sites.

  1. A man named Johannes Lipperhey from Middelburg ‘‘invented‘’ the telescope. But unfortunately for him, he could not get the credit because to other men named Sacharias Jansen, who was also from Middelburg, and Jacob Metius from Alkmaar. One famous astronomer, Galileo Galilei, discovered the craters and mountains on the Moon, the phases of Venus, Saturn’s rings and Jupiter’s moon’s. He also really got into the stars. He proved that the Earth was not in the center of the solar system. A Polish astronomer named Nicholas Copernicus discovered the sun was the center of the solar system.Telescopes have improved over the centuries; now, we have digital telescopes and telescopes in space like the Hubble Telescope which takes pictures and sends them back to Earth so we can understand more about space. Space is bigger then we can ever imagine.

  3. Telescopes

    There are two types of telescopes, reflecting and refracting. Refracting telescopes use lenses to bend the light. It does this by bending the light up side down and aiming the light through a smaller lens which focuses it in to your eye. The reflecting telescope reflects light off a concave mirror to hit a triangular mirror, bouncing the light to your eye. There are other types of telescopes but they do not use light gathering as their way of viewing space.
