Moon Crater Experiment

We read an adorable book about the moon and this moon crater experiment was a great way to continue the adventure from the book.

The book: 
This was one of the books The Dragons picked off the shelf.  Our theme for preschool this week was space, this book has a big moon on the front so they picked it out.  It looked like an adventure book as well so it was very fitting for the week. 
Opening up this book was an adventure all right! I enjoyed reading it and The Dragons enjoyed listening. They were very intrigued with the man who kept coming into the boy's room.  He was so mysterious.  In the end of the book the little boy goes to the moon to have his own adventure.  The pictures in this book were big and beautiful.  

The pictures of the moon showed the craters.  In other moon books it is a glowing ball so this was perfect for out experiment. 

Set up

  • small pan or bin
  • flour
  • marbles or jaw breakers
  • imagination
For this experiment you only need to cover the bottom of the bin or pan you are using with flour. 
I put a bit extra in because I knew The Dragons would be playing in it afterwords. 

Before we started dropping the marbles we had to engage our imaginations for the adventure.  I told The Dragons we were giants up in space and the marbles were our asteroids.  The bin was the moon and we were going to make big craters in the moon with our asteroids.  They agreed this was the best was way to conduct the experiment. 

Using marbles The Dragons first dropped them in one at a time while sitting down

We observed the craters

Next they dropped them in standing up
And observed the craters

What is different about the craters? 
  • The craters made while sitting down were smaller and the marbles stayed in place. 
  • The craters made while standing were bigger and deeper.  The marbles also bounced to make multiple craters sometimes. 
Why would this happen? 
There were many ideas that I don't remember now, some made sense some were very silly.  We did discuss the ideas through the end to discover if they were possible.  

Then I explained when a meteor is coming from farther away it has more speed thus the impact is greater. 
When a meteor is closer to the moon and hits it it is traveling slower so the impact or impression is smaller. 

They reexplained this concept to Jerry during lunch, which was neat to see them understand and excited about science! 

Then it was time for the giants to play in the dust of the moon :)

Teeth Craft

This craft went with our meat eater unit you can see here

I was having a difficult time thinking of activities for meat eaters.  I didn't want the sole focus to be on dinosaurs because carnivores and herbivores is a way to categorize many animals today. But everything I was running into was dinosaur related. 
Finally I found this craft! 

paper template of a carnivore and herbivore (I drew a hippo and t-rex head outline) page of teethscissorsgluemarkers

Little Dragon cut out the heads and then the mouth pieces. 
Then he cut out the teeth and glued them inside the mouth
To finish it he drew eyes on the head and a tongue on the inside of the mouth. 

Little Dragon was very excited to see the finished animals and open their mouths to look at their teeth.

We wrote what the animal was on the inside

This was a fun easy craft that helps identify the difference in the teeth between carnivore and herbivore.  It is a visual reference that can be used again and again.  It can also be used for…

Paint Squirt Gun Fight

I was waiting for the perfect opportunity to do this activity ever since I saw a post about painting with squirt guns.

Paint squirt gun fight!  And it was AMAZING! 
I first bought an 8 pack of large boys white t-shirts.  I wanted the shirts to fit all of the kids and I wanted them to be able to save the shirts for the future. The 8 pack was perfect.
I filled the water guns up with paint and a pinch of water.  Each gun had a different color so we could determine a 'winner'. 
I squirted each 'player' with their color first.  So they knew their color and to demonstrate where to aim. 

Talking about the aim was very important.  All of the kids involved were 4 and above.  Aim had to be in the tummy or the back.  No faces, bottoms, heads/hair, or legs. We didn't want paint in eyes, noses, or mouths. The other places would be more difficult to clean and giving two aiming places was simple.����������������������������������������������������������������������������������������…

Elephant Faces

Elephant Faces (masks)
We used: 

Three paper platesPaint or markersPaint brushesStaplerScissorsYarnFirst paint the bottom of the paper plate.  While the kids painted I cut the other paper plate in half for the ears. Using the third plate I cut out the textured part of the plate to make the trunks.  
Paint (or color) the rest of the pieces. 
Staple them together to make an elephant.
Cut out small holes for eyes and small holes behind the ears to attach the yarn.

Now that the lesson is over I have the masks hanging in the playroom.  They make a neat decoration.
