Or, at least that these people had access to some very potent drugs. Moving into the Common Era we have the piece below. A classic “temple step” design suggests the piece below is solidly in the Nasca period.Yet this powerful and distinctive style tells us both how old the piece is and where it is from. The “proliferous” style graphically combines images of eyes and mouths to create figures within figures which places it in the proto Nasca era. It is carbon dated to about 320 AD, only slightly later than the previous piece .

Next we have the “jagged edged serpents and jaguars” of the Moche, carbon dated to about 820 AD.

The “war-like abstractions” of the Huari are instantly recognizable in the “Skull” tunic below and of about the same age as the Moche piece above.

Students will be introduced to being science/math detectives by trying to figure out the relationship of organisms using graphs.

Students then are introduced to the controversy around the Shroud of Turin, which has been carbon dated.

Her first piece was from the Chavin culture (1,000 to 400 B. The menacing faces, fangs and claws of Chavin art are unmistakable and when we see them we can say with confidence that the textile is amongst the very earliest decorative Andean textiles. On the South Coast of Peru Paracas culture followed Chavin and produced textiles with distinctive surreal floating figures.

Some Chavin images can be quite unsettling as in the piece above. As we look at the other-worldly “floating shamans” in this Paracas textile, it is easy to start believing in Aliens.

The Oxalic acid standard was made from a crop of 1955 sugar beet. The isotopic ratio of HOx I is -19.3 per mille with respect to (wrt) the PBD standard belemnite (Mann, 1983). T designation SRM 4990 C) was made from a crop of 1977 French beet molasses.

The Oxalic acid standard which was developed is no longer commercially available. In the early 1980's, a group of 12 laboratories measured the ratios of the two standards.

This lesson can be used as an introduction to radioactivity.

Students should have familiarity with the scientific notation and the units milli, micro, and nano.

Then students will analyze an article written about the C-14 dating of the Shroud of Turin and draw conclusions.
