PRODUCT DESCRIPTION

This is an ACTIVITY to help students visualize the immense amount of time needed for certain evolutionary events to take place. A FOOTBALL FIELD is NOT necessary but makes this activity a lot more engaging for students. Students also have a chance to practice the MATH concept of proportions.

TEACHER NOTES*********************************************************

1. After students complete this handout, I usually make use of the football field and have students show me where each event occurs. I try to use the orange hazard cones to mark each event in order for students to see/experience the amount of time that passes between each. I also demonstrate THEIR approximate time on earth as the thinness of a blade of grass.
2. If you don’t have a football field, you can just have students mark the 2-D one on the back of the handout for perspective. Of course the last events will stack up on each other so they’ll have to decide how to best show these.
3. Sometimes I don’t have students complete all of these but rather have them do a select few as a group and have them present them in class or on the field.
5. The “exceed expectations” portion of this activity is designed to be a bit more challenging. Students will need to do a little research on radiometric daitng. I’ve given a Wikipedia link as a starting point for research. You may want to include it on the student handouts. Not sure how much freedom you want with this but it’s a great exercise in understanding the limitations of science and how science deals with these limitations. You could also substitute this section with extra events that students would have to research and present.
6. EDITABLE! Feel free to edit this to fit your needs.
