Geological timeline and Extinction events -
After a quick review of the taxonomic classification of living things, Chase worked on an extinction lab. She was given a roll of adding machine paper and a short description of extinction events. We used the paper to create a geological timeline, starting with ‘today’ and the millimeter width line signifying human existence. We then rolled out 5 meters of paper along the counter. Using the scale of one meter = 1 billion years, one centimeter = ten million years, and one millimeter = one million years, Chase marked off the geological eras. She then determined where to mark off significant times in the Earth’s history; the first appearance of bacteria, plants, animals, etc. Once the timeline was completed, I gave her the dates of the five (or seven) extinction events we know have happened for her to mark on the timeline. Once the project was complete we discussed the significance, causes, and result of each event and answered several questions I had prepared for her to answer. We made plans to meet on Monday for a field trip to see the sea turtles.
