Yesterday, we read about oil exploration and so, we pretended to be one of the oil explorers. I found the directions online.
We filled a shoebox with sand and small stones and somewhere in between, I hid a small plastic box with green colored water to represent oil. We closed the shoebox and we taped a graph paper on it. Marked the directions for North, South, East and West. Then the kids started exploring for oil by digging into our pretend earth with skewers. When they hit the spot, we used a big dropper to suck out the oil. Kids really had fun doing this.
