Evaporation Science

As much as I love science I am bad at remembering to do science projects. Lucky my dragons love science and are always asking questions, so when the opportunity presented itself Little Dragon asked if we could do a science experiment on evaporation.
He had been learning about the water cycle in preschool which is what brought this on. 

We were outside doing our shape science when he asked if we could do another experiment.  
He had it all planned out. 

He wanted to fill up a container with dirt
add water
and watch it evaporate. 

For some reason Little Dragon thought you had to have dirt for water to evaporate.  I explained that water needs nothing but heat to evaporate and demonstrated this by showing him the cement drying in the heat of the sun from our earlier experiment. 

He seemed to understand and gave me a few examples of water evaporating without dirt. 
Such as: 
after it rains
rivers
puddles

Although he now understood dirt was not necessary for water to evaporate he still wanted to add water to the experiment.  I told him his results may change with he dirt but he didn't mind. 
He got started on his experiment. 

What he wanted to know was how long would it take for all of the water to evaporate.  We knew it would happen (or at least I knew and he was told but wanted to see it for himself).

He added some water


We put a sign on the container so none of the neighbors would think it was something to play with


and we put it in the hot sun

The first time we checked on it there was not much change because we finished getting it put together later in the day. 


The next day it rained and filled our container back up. 
Little Dragon thought this was cool too. 


We checked it a couple days later and found the dirt dry and the water gone! 

It took about 2 days for all of the water to evaporate.

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! 
Materials: 

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.
