Spatula
Clean, uncontaminated spatulas are used for taking samples and putting them into sealed containers. Researchers can examine these samples in the laboratory. Researchers take samples for a variety of reasons. Samples of the residue from a fire can be carbon dated. Researchers sometimes examine soil samples to find grains of pollen that can help them determine what types of plants grew in the area and also the climate. Researchers can even tell what types of crops were planted and when large areas of trees were cut by examining the pollen!
