Fossil dating worksheet
This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.
In reading earth history, these layers would be "read" from bottom to top or oldest to most recent.
INTRODUCTION Scientists have good evidence that the earth is very old, approximately four and one-half billion years old.
This also means that fossils found in the lowest levels in a sequence of layered rocks represent the oldest record of life there.Materials: two sets of sequence cards in random order (set A: nonsense syllables; set B: sketches of fossils), pencil, paper Procedure Set A: 1) Spread the cards with the nonsense syllables on the table and determine the correct sequence of the eight cards by comparing letters that are common to individual cards and, therefore, overlap.The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence.In this activity, students begin a sequencing activity with familiar items letters written on cards.Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.
For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed.
