BARK PAINTING dates to the early 19th century when it was noted by early European visitors. Its origin is in question due to the perishable nature of bark.

The Eucalyptus tree provides optimum bark for painting. It is harvested in the wet season, then placed over a fire to dry. The bark is then weighted with rocks to flatten it. In a couple of weeks, the bark is dry and ready to use.

The Dreaming stories, captured on bark, depict animals and ancestors, handprints, mythological creatures and, most recently, European ships. These pictures provide a record of vast changes in environment and lifestyles. Although the rock art of 1000 years ago depicts birds and plants that provided new food sources, this theme is also found on bark painting. Newcomers to the Australian continent of 400 years ago are represented in the form of things they brought, including modes of transportation, ie, ships and horses.

Create your own bark painting. Locate bark from trees that have been cut down. Use a piece in its natural form, about 12 inches square (fallen pine trees that are a bit rotted have excellent bark samples, easily peeled).

CARBON DATING allows scientists to figure the age of ancient objects. Explore the methods of carbon dating. Investigate how the process works and what needs to be in place for the process to successfully find the age of an object. List several objects from a newly discovered cave which, after carbon dating, might tell the story of the cave’s occupants.
