Our Year 3 pupils have been delving into the fascinating world of fossils, discovering not only how they are formed over millions of years, but also how to recreate the process in the Science Lab.
Excitement levels were high as the children donned lab coats and goggles for their first lab lesson. They set out to make a “fast-forward” version of fossil formation, transforming classroom learning into a hands-on experiment.
The activity began with softening and moulding clay to represent layers of sedimentary rock – the kind of surface on which ancient creatures might once have lived and died. Each pupil then selected a bone, shell or tooth to press into the clay, creating a detailed imprint. Just as in nature, this imprint became the mould that, over time, would capture the exact shape of the original.
To simulate the slow process of mineral replacement, Plaster of Paris was poured into the moulds, which set overnight. The following day, like palaeontologists uncovering fossils, they carefully excavated their creations, revealing beautifully formed casts.
This creative and immersive lesson brought scientific theory vividly to life, sparking curiosity and building practical skills.
