We can’t observer how the universe formed, but scientists are still willing to say that we know the universe was created through a Big Bang. In this scenario, students will learn the three main lines of evidence for the Big Bang: the universe is expanding, the Cosmic Microwave Radiation, and the mixture of chemical elements.

Inspiring Science Education hangout on 27 May 2015 discussed ‘The Big Bang’. If you missed the live hangout, enjoy the video of the recording and stay tuned to the future hangouts.

This is series Hangouts on Astronomy and Planetary Science supported by Ellinogermaniki Agogi and NUCLIO in the framework of the European Science Education Academy and the Galileo Teacher Training Programme. Hangouts are hosted by Dr Pamela L. Gay. GTTP invite you to work along with the series to create classroom educational materials while earning badges as you progress.
