Discovery Bottle

This is the second time we have tried discovery bottles and this time the results were much better then the first.
The first time I made the discovery bottle.  All The Dragons wanted to do with it was open it up to see what was inside instead of looking at the items through the bottle.

This time I set out different items and let the kids create their own discovery bottle. 

One thing we were focusing on this week was the color blue, that is why there blue items.  The cotton balls I added because I thought it would be fun for them to push inside the bottles.  I would have never thought to add clothespins to a discovery bottle, I got this idea from my lesson plan at motherhoodonadime

The discovery bottles were a mathematical science activity. Who knew putting stuff into a bottle could be called science and math! 

We started with a question: How many items can you fit in the bottle?
How many clothespins? 
How many cotton balls? 

They started off counting the items they were putting in but soon lost count when they started adding handfuls of beads and marbles (of course). 
But they continued filling and filling until the bottles were full. 

When they were finished filling them up I asked them to dump them out so we could count how much stuff they shoved inside.  They were very excited to dumb.  As it goes dumping is a favorite for preschoolers. 

Dump them out! 

Pull out the cotton balls

Shake out the rest!

Then the counting started.  The Dragons counted them first, then I helped them count them again to make sure we had the right number. 

Doll Dragon had a 20 oz bottle and had 36 items. 
Little Dragon had a 16 oz bottle and had 42 items. 

This is where volume comes into play-mathematical science! 

We asked The Dragons why the smaller bottle had more things inside it?  We gave The Dragons some time to examine the items on each tray. 

Doll Dragon saw that Little Dragon had more small items and less big items.  She had more big items then small items. 

Bigger items take up more space where smaller items take up less space.  Thus Little Dragon had more items in his bottle.

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.����������������������������������������������������������������������������������������…

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…

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.
