Blast Off!

Projectile points, arrow heads, atlatl (spear thrower), archeological sites, tools, stone tool making, debitage, excavation, discovery, chemical reaction, bones, burial sites. The Nurseries are expanding their vocabularies and minds while they take part in some wonderful experience with Jeff White, our resident archeologist.

On Monday, there was a lot of looking, listening, and handling of artifacts plus some archeological basics. On Tuesday, each child excavated artifacts (m&ms) from an archeological site (chocolate chip cookie) with a tool (tooth pick). They also each excavated an actual stone projectile point from a ball of play dough. Brian and I labeled sandwich bags with their names to help them keep their personal artifact safe.  Later, back in the Nursery room, several children tested out their projectile points by carefully poking the points through a series of circles they had drawn on paper.

"Look it actually pokes through."

"It saws!"

On Wednesday morning, Archeology was put on hold for the Nursery while the Dayton Philharmonic's String Quartet performed "Goldilocks and the Three Bears" in the Art/Science room. The Kindergarten came, and the parent volunteers, who were in the hallway helping with the school mailing, got to listen to the fine concert as well.

On Thursday, and back to Archeology, Jeff had bins of sand marked off with grid lines ready for excavation. Projectile points and some pottery artifacts were found. After they finished with that, on the floor on a blue tarp there were two much larger bins of mulch also marked off with grid lines for the Nurseries to excavate. They found bones (molded blue plastic) and many other artifacts in each. One child even found a golden earring in one of the bins (burial site). Jeff asked lots of questions and here were lots of answers.

On Friday, Jeff talked about chemical reactions and escaping gases. The Nurseries watched some chemical reactions and beautiful changes happening in their individual home made lava lamps: water and oil and food color in a small mason jar to which Jeff added a half a tablet of alka seltzer. Afterwards, Jeff set up another experiment with small cylinders with lids (film roll sized), water and (drum roll please) more alka seltzer! Jeff asked questions about what they thought would happen. People thought a long time and then one child smiled, his arms shot up into the air and he joyously proclaimed, "Blast off!!"

That is exactly what happened.
