Making a Time Map for
Hands On Assignment Lesson 1
In this course we will be dealing with time spans that are
beyond our ability to imagine. However, we can try to understand
the time intervals for events. We will make a simple time model
of the events that have occurred in our universe so far.
|| Each group will receive 15 index cards
and some scotch tape.
||The universe is thought
to be between 12 and 15 billion years old.
Each index card stands for one billion years.
Tape the index cards together to make a long row of cards.
The orange is where the tape should be. Number each card.
Now let's put in the significant events.
On the left hand edge of the first card, make a line and label
it "The Big Bang". This represents the beginning of
the universe. All the matter in the universe suddenly appeared
in less than a second! Where we are today is on the right
hand edge of card 15.
Now let's put in some information
about the evolution of life on earth.

10 billion years ago.
Mark this event on the correct card.

sequence star 4.5 billion years ago.
Find the right card and label it. Think
