Year 3 Science
Lesson: Science
Class: Year 3 Year: 2017 - 2018
Year 3 have been working very hard on their rocks topic in science and they would like to show you some of their most recent investigations.
The 'Choc' Cycle
To help the children understand how each different type of rock is formed, we used chocolate to speed up the rock cycle. Melted chococlate represented igneous rock being formed underground from magma and lava. We then grated the chocolate to show the effects of weathering and how rocks break up into bits of sediment. Next, we layered the different sediment on top of each other to represent the formation of sedimentary rock. Finally, we used pressure and heat from our hands and squeezed the sedimentary rock to show how metamorphic rock is formed. The children recorded their observations as we went and they were able to use the correct scientific vocabularly.
Fossils
On Tuesday, the children looked at images of fossils and discovered four different types; trace fossils, body fossils, cast fossils and mold fossils. The children made excellent information posters about each fossil before making their very own mold fossil! These are currently drying out but once they are dry, the children will be able to take their fossils home.
