ODONTOLOGY forensic science day

SAFETY FIRST includes:
a clay nostril covering to avoid burnt tooth powder odor.

So glad to be at THURSDAY!

here is our day:
I swept the back porch after stepping on a thorn. barefoot.

9AM- Ninja Training. our Magic Number was 15. We did Push Ups, butterfly Sit-ups, Floating Leaf, Frog Stretches, The Mantis Pose, and jump rope.

10AM- Odontology: each boy had a tooth to investigate. Draw a detailed picture, label areas, name tooth type, cut tooth open and use magnifying glass to look at internal structure.
All boys did a great job. They used different magnifying apparatuses and drew good pictures. they identified their teeth. Connor had a canine, the others had premolars.

Dremel was used. I think the boys had a lot of fun! They tried a tiny hacksaw and chisel and hammer. it was good to start the cutting with the dremel then use the chisel to finish the job. It was cool! They found the pulp chamber and what looked like a left over nerve or vessel sticking out. Shining the UV light on the teeth, esp the insides, was neat, too!



Plus we scraped the cavity tooth and looked at the decay under a microscope- after looking at the cavity with magnifying glasses and writing down some details. THIS was NEAT!!!! but, no pictures. sorry.

I found the mold/cast of the teeth- the dentist gave me.. but I can NOT find the X-ray! darn darn. We made our own casts and checked out X-rays online and found cat teeth Xrays.

Ki made Brownies.

Gavin made Guacamole.

That was the fun part of the day. Now they will do their math and reading on their own.
