Fossils - 29.9.21

Wednesday 29th September 2021

What are fossils and how are they made?


Today we recapped our previous knowledge about 'Rocks'. We remembered the 3 different types of rocks, Metamorphic, Igneous and Sedimentary. We also discussed how they are different and their recognisable differences. 


We then looked at Fossils. We learned that fossils can be made in a number of ways, and focussed closely on 2 of them. A 'Mould' and 'Amber'. 


We used a 'salt dough' mixture to make a tough dough that we could imprint small figures, shells and other objects into. This left a imprint, as would be found in Sedimentary rocks. We watched a video that demonstrated how the layers of sediment built up on top of the dead animal, until an indentation is left in the rock and uncovered when the rock rises above sea level. 


The amber fossil lead us to melting candle wax. The wax represented the tree sap that would trap insects and form an amber fossil once solidified. 


Take a look at our photographs from our fun, interactive lesson.
