Dinosaur Excavation in Preschool

Picture 1168We buried dinosaur bones in the sand box. They are actually cow femur bones. To clean them you can boil and then simmer them  for around 24 hours on each side in apple cider vinegar. Just to warn you the smell is AWFUL! and it seeps into everything my house will never be the same. Some butchers have a machine that will completely clean it for you ask around.

Picture 1159The kids dug up the bones and then carted them off to the museum. They then decided which animal each bone went to and sorted them out accordingly!

Making Fossils

Dinosaur Excavation Sensory Table

Museum- Imaginary Play

• Some bones, fossils etc
• Plastic bugs
• Sea shells
• Plastic Dinosaurs
• Magnifying glasses
• Kaleidoscopes

You will need to Create, Collect, or get donations for the following:

• We need some chicken bones preferably leg bones use hydrogen peroxide to bleach the bones.

• Dinosaur Eggs and Geodes go here for instructions on how to make Dinosaur Eggs and Geodes

• Instead of doing plastic bins I thought it should look more like a real museum with displays so I made display trays [picture frame take out glass use back board cover in felt and put back in frame] for all the “exhibits” they are really cute and the kids can take the trays out play with them and easily put them back.

Under the stairs we will have a planetarium use fabric to darken the area we need to figure out how we are going to hang it use a planet light that will cast stars and other fabric that will be in this area as well. Since the light thing will be casting the light I was thinking it would be fun if we also hung CD’s from the ceiling area under the stairs the light will cast a rainbow effect which could be pretty cool.

I added Fabric that will cover all the turned over furniture.

You can see above how I covered the table with fabric so it looks like a nice display not an overturned table

I have donated a tiered tower which we are now calling the Sensory Tower.

We have Science Bottles

Feelie Gloves
Sound Jars
Smell Jars

Sensory Baggies

Rainbow Stew Baggies
and anything else super sensory oriented.

Click on any of the Sensory item pictures above or on their link titles for detailed instructions on how to make them and find some great ideas.

• For the OBJECTS for display trays that we made I was hoping to go for a natural History theme. Use fossils, shells, arrowheads, rocks etc add any ideas and items you might have.


• We have baskets on the bottom row which have rocks, drift wood, dried flowers, silk flowers, and some different textured materials and some pinecones.

Silk flowers

Drift Wood

Pine Cones
• Use a framed mirror that lays flat and some Crystals and glass stones to put on it I placed flashlights near this so the kids can look through the crystals with some flashlights. Click the following link to see more activities with LIGHTS, MIRRORS, and GLASS

Mirror, beads, and lights. There is a lot to look at and explore here

• Try to catch a caterpillar and other real bugs maybe a plant (African violet) in a two liter bottle so you can see the roots growing you can throw some worms in there to. Set up life cycle.

• I also thought it would be fun if was had a weekly science experiment going on on top of the shelves I was thinking we could do colored flowers. By taking 3 or 4 white carnations and putting them in water with food coloring they will change color we could even split the stem of one and stick it in two different colors to see how the flower will change. I was also thinking of making a dinosaur egg another week by sticking a hardboiled egg in vinegar (it turns all leathery).

• I donated a Pheasant (it was real once) put it on display

• magnifying glass on each board

• Journal area- basket of paper and pencils/ crayons children can record their findings

* Sorting game bugs or buttons

• Small binoculars upstairs on loft attached with yarn or string.

• Plastic insects set up a terrarium or two for play exploration

I also created this…I guess ramp? Connecting the two mail chutes from when I made the Post Office Imaginary Play. I put a bucket attached to a pulley system so once the balls go through the ramp they fall into the bucket that can then be pulled up so you can start over.

Our Gravitiy, Inertia, Propolsion Testing. I also used this in the Space Station Imaginary Play
I  created this out of cardboard packing material

We have a basket at the bottom and a bucket connected to a pulley system that takes the bucket up to the loft

The boxes you see on the side actually create an air vortex by pointing the side with the hole in it at the Styrofoam cups you can hit the sides of the box and shoot the air out in a direct path or vortex and knock down the cups. The wood stand is there for the children to place a box on and aim at the cups.
Picture 141
The wood stand is there for aiming you can actually aim at certain cups etc.

I made a wind tunnel. Using packing material and the clear sheets you use for an overhead projector taped together. I then bought a fan from Walmart turned it facing up and now we have an awesome wind tunnel.

The kids stuff scarves, coffee filters, and my favorite balloons up inside the tube. Than watch the fan push them through and all the way up to the top of the loft they then fall down gently. This is so awesome!

I also made a pendulum out of some spare PVC pipe. It was super easy and took me only ten minutes to make. We actually tell the kids to try and miss the tower they create. Then they have to wait for the ball to completely stop before they try again.

I also made another type of wind tunnel learn how I made it here

Rainbow Stew- Color Mixing without a Mess

Materials Needed:
1/3 cup sugar
1 cup corn starch
4 cups water
Food Coloring Red, yellow, blue

1. Mix together all of the ingredients in a sauce pan over medium heat.
2. Stir constantly until the mixture begins to thicken. You should be able to drag a spoon through the mixture like below

3. Remove from heat and let cool.
4. Divide the mixture into three bowls.
5. Add a different color of food coloring to each bowl.
6. Put approximately three tablespoon each of two colors into a zip-lock baggie.
7. Push out all the air in the bag and then seal the bag and tape the top closed.
8. I double bag sealing each baggie with clear packing tape.
9. Once the top is sealed go around the perimeter sealing all edges for durability
10. Let the children knead the baggies to mix colors.

**I like to only do TWO colors at a time or one color that way the baggies last longer you can still play with a purple baggie and it looks pretty but brown and black baggies are not so cute and that is what happens when you mix more than two colors.

Dino Eggs or Geodes

Dino Eggs or Geodes

Coffee grounds – Go to Starbucks ask for Donation
1 cup of used coffee grounds
1/2 cup or so water
1 cup of flour
1/2 cup of salt
wax or parchment paper
mixing bowl
small objects to put inside the dough like small dinos or stones

Stir the together the coffee grounds, water, flour, and salt until well mixed.
Add water as needed. It should be like a thick dough.
Knead the dough together and then roll into a ball insert a small dinosaur or plastic gem etc in middle roll back into a ball (or Dinosaur egg)
Put onto the waxed paper or aluminum foil.
Bake at 275 degrees for about an hour.
Check to make sure they are hard and then remove.
Make sure to flip them over once taken out the bottom is always a bit wet still so once out if you flip it the “egg” will dry out overnight.

**Triple or quadruple this recipe to make enough for the school**
