Messy Mondays: Dinosaur Excavation

Josiah is pretty certain he's going to be a paleontologist when he grows up.  Not only can he name dozens of dinosaurs but he can tell you tons of facts about each one - like if they are a herbivore or carnivore. Instead of riding his bike or playing ball, he has spent the summer discovering "fossils" around our yard.  He's quite satisfied with pretending our broken sidewalk is fossils but I thought I'd try my hand making it a little more realistic. So last week we buried and excavated a toy dinosaur.
Burying the dinosaur
1- water, 2 old plastic bowls, plaster of paris, coffee grounds, dollar store dinosaur, Cooking Spray 
2 & 3-  mix plaster according to instructions adding coffee grounds
4- pour 1/2 plaster in to bowl, wait about 3-5 minutes until plaster is thick, 
spray dinosaur with cooking oil & set in plaster, pour remaining plaster over dinosaur, let set over night

** before using Plaster of Paris: make sure you throughly read the instructions on the container, since it can cause 
injury if not used properly.  You may also noticed that Micah was missing for this activity - that's because he still
 eats everything and Plaster of Paris is not something to be eaten, or even tasted.  
The excavation
Tools: hammer, chip brush, safety googles
This was very serious business, no smiles, no giggles, just complete focused on his "work"
The reward
Still all business

It was a lot of fun watching Josiah do this activity, as he was very focused and precise the entire time.  He would hit the plaster with his hammer a couple times and then careful brush the dust away examining for any exposed bones. We'll definitely do it again sometime with just a few adjustments.  I added the coffee grounds to make it a more interesting color and to hopefully weaken the plaster, next time I think I'll add a lot more grounds and maybe another aggregate like sand.  The plaster was still pretty solid, which kept Josiah busy for awhile. Daddy eventually helped with the big hammer.  Josiah was happy focused the whole time but I'd like to make it a little easier to get to the dinosaur.  For a budding paleontologist it's a perfect activity.

A Little Red Cardboard Barn

We've finished our farm unit and are moving on to a new theme tomorrow - but before we do I wanted share the barn we made. The wooden farm animals came with a beautiful handmade ark that we gave Big Buddy for Christmas a couple years ago.  I would someday love to have a wood barn but it's currently not in the budget. So in the mean time we decided to improvise and make our own.  I stumbled upon this perfectly sized milk box (4 gallons per box) while subbing and thought it would be sturdy enough to handle play. Hubandie and the boys used an x-acto knife and wood glue to build a barn shape. to get the doors to fold out hubandie used an x-acto knife and scored the inside of the cardboard We then painted with a basic primer and outlined a window and a door with painters tape. cardboard is very porous so priming is a must if you want decent coverage Big Buddy however insisted that we add more windows so it looked like the barn in our book The Big

Preschool Syllabus: Dr. Seuss

Normally I'd do a Dr. Seuss unit in March around his birthday. We had to do one now though because on Saturday Big Buddy and I going on a date to a  Dr. Seuss exhibit . The exhibit is only at the museum until January and I'm afraid if we don't go now we might not get the chance. We are of course reading lots of Dr. Seuss's books. A great advatage to studying Dr. Seuss in November rather than March is that all his books were available at the library. I also found a great children's biography which is perfect for preschoolers. Pebble First Biographies: Dr. Seuss  We've read it a couple times and Big Buddy loves reciting all the facts he's learned WRITING CENTER ADDITIONS big buddy's name in sand paper letters, coloring pages  & mazes from seussville.com skills practiced: fine motor, letter recognition, creativity,  reading comprehension LEARNING "TRAYS" -   I rotate these, setting out about four a day from which the boy&#

Jack-O-Lanterns on the Fridge

Last fall I saw the idea for refrigerator pumpkins with face pieces in FamilyFun Magazine  and have been anxious to recreate them ever since. It was pretty quick and easy and since the only thing we didn't have on hand was magnetic sheets ($1.50 with coupon at Joann's) it was also very cheap. my supplies: magnetic sheets, orange & black construction paper, white pen, tacky glue *i know they have self adhesive sheets but my Joann's didn't carry them   glued (very messily) and ready to cut Both the boys were quite enthused when they discovered them after rest time :) Hopefully it will keep them entertained until we carve real pumpkins.
