The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Teaching about Earth's history is a challenge for all teachers.

Such material, called detritus, consists of fragments of rocks and minerals.
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.
This type of sedimentation is referred to as chemical sedimentation.
Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water.
They usually consist of layers or ; hence they are also called stratified rocks.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.The accumulation of plant matter, such as at the bottom of a swamp, is referred to as In general, the coarser sediment gets left behind by the transportation process.
