After having read about oil exploration, we repeated the experiment that we had done with Kabir in 2014. We filled a shoebox with sand and small stones and somewhere in between, I hid a small plastic box with green and blue colored dishwashing liquid to represent oil. We taped a graph paper on top of the shoebox. We marked the directions for North, South, East and West. Then Arjun started exploring for oil by digging into our pretend earth with skewers. When he hit the spot, we used a pipette to suck out the oil. He had fun doing this.
