Be familiar with Earth's history.
Learn the changes that Earth underwent over its history.
Create a timeline of Earth's history.

","materials","

For the class, prepare:

Meter stick of measuring tape
Masking tape
String or yarn. At least 5 meters long.
Colored construction paper

For each group of students, prepare:

Events/Timeline cards print out

","preparation","

Measure out 4.6 meters in a straight line.

Place a piece of tape every half meter from the beginning. Each meter represents 1 billion years of earth’s history, each centimeter represents 10 million years, and each millimeter represents 1 million years.

Mark the first piece of tape as the present, the next piece as 500 million years ago, the next as 1 billion years ago, and continue on. The last piece of tape will read 4.5 billion years ago, add one extra piece of tape at the end to represent 4.6 billion years ago and the formation of the planet.

Add one extra piece of tape at the end to represent 4.6 billion years ago and the formation of the planet.

Make sure all materials are ready and accessible for students.

","worksheets","","multimedia","steps","

Introduce the topic to students. Ask the following and discuss the following:
- How do people figure out that the Earth and life on Earth have changed over time?
- How does the movement of tectonic plates impact the surface of the Earth?
Break students up into small groups. 3-5 students per group. Each group will get a subset of the 15 event cards (see included PDF “Timeline Cards” – these should be cut up along the black lines).
Each group will get a set of cards printed out on different colored paper. The sets can be marked with colored markers to distinguish between each group.group. All groups can place their ‘formation of planet Earth’ card at the beginning of the timeline.
Ask students to work together to place the rest of the event cards in the appropriate place along their timeline. The students do not need any prior knowledge to put their events on the timeline – the idea is for them to work together to figure out their events – let the students know it’s OK to be wrong!
After the discussion, work with the students to place the events in their correct location along the timeline. As you re-place each event, engage the students in a brief discussion.
After the discussion, work with the students to place the events in their correct location along the timeline. As you re-place each event, engage the students in a brief discussion.
Discuss any events that the students were surprised by. Note that the last two events will be totally indistinguishable from each other and from the end of the timeline – this is key! Events that we think of as being really old, like the extinction of mammoths, are actually very recent when compared to the entire history of the Earth. Discuss any other thoughts and observations that students have.
