Day 147 – The Expanding Universe


Science 9 – As part of their learning about the Big Bang and the expanding universe, students do an activity where they model this expansion with balloons.  They noticed that all of the galaxies move away from each other and that the expansion goes in all directions.  To help with these topics, I’m using parts from the Perimeter Institutes resource package.

Pseudo Day 120 – Universe Expansion


Science 9 – May 12

Students used balloons to model the concept of universe expansion and how galaxies move away from each other. This model does not accommodate gravitational effects between galaxies.
