Educator How-to: Teach archaeology with edible excavation

It’s time, once again, for our monthly Educator How-To! Today we’ll help you teach kids to keep track of what they find — just like an archaeologist does.

Archaeologists keep careful records, as do all scientists. One important way to keep track of their work is by mapping where each artifact is discovered. Show your students how to plot artifact locations onto a grid with this tasty activity!

Materials
• Large chocolate chip cookies with lots of chips
• Toothpicks – 1 box
• Waxed paper sheets
• Cookie grid
• Markers
• Masking tape
• Ziploc baggies – 1 per child

Procedure

1. Tell the students that they are going to be excavating a chocolate chip cookie. And just like a real archaeologist, they must record where each “artifact” is found. In addition, they must be as careful as possible to get each “artifact” out of the “dig site” with the least amount of damage.

2. Supply each student with a cookie, a piece of waxed paper, a toothpick, a pencil, and a cookie grid worksheet.

3. Students should carefully draw a grid on their cookie using a black marker. It should match the grid on the worksheet cookie as closely as possible.

4. Students should then carefully excavate the “artifacts” out of the cookie trying to cause as little damage to the “artifact” (the chips) or the “dig site” (the cookie).

5. When they retrieve an “artifact,” they must assign it a number and plot it on the cookie grid. When an “artifact” is removed, it should be put on a small piece of masking tape and numbered.

6. Give each child a baggie to put all of their “artifacts” in.

7. When the time is up for this activity, count each child’s “artifacts” and look at the condition of their “dig site” to determine the most successful archaeologist for the day.

While we are working with cookies here, we do not advise eating the dig site or munching on your priceless artifacts — extra cookies are recommended!
