Cleaning Coins

For our money theme a perfect science activity is cleaning coins!  
I knew we would be using money a lot for our money theme and handling clean money is a better option then dirty money that has passed through hundreds of fingers.  

Cleaning money is simple and most of the supplies are already in your home. 

  • Vinegar
  • salt
A quarter cup of vinegar to 1 tablespoon of salt for the solution.  













Let the coins soak in the solution for a bit
 then take them out of the solution and wipe off the grime with a towel and watch them shine!

We did talk about the vinegar breaking down and lifting the dirt for easy wipe off.  The Dragons were so excited to have a pile of their own 'real' shiny money that they didn't pay much attention to the science of it. 

When the money was clean it was time to play with it.

Painting With Squirt Guns

We did this as a Fathers Day project, but it fits in outside play perfectly.   I liked this for Fathers because it was an interactive activity for the kids to do with Jerry to celebrate him and the time they enjoy spending with him. I filled 1 gun with yellow paint and 2 guns with black paint.  The squirt guns we used were from the dollar store and had a decently big hole to pour the paint into.  Some squirt guns have itty bitty holes that make squirting paint into the gun very difficult. Taped off the canvas...and made the kids pose Then the guns were handed to the kids and dad.  Instructions were to shoot the canvas not each other. Very simple. Start squirting!   The squirting went on and on.  I refilled the guns a couple times so the activity could continue.     Jerry also took time with each Dragon to squirt with them.  With a Star Wars theme we were looking at having black as the primary color and yellow as the secondar

Elephant Faces

Elephant Faces (masks) We used:  Three paper plates Paint or markers Paint brushes Stapler Scissors Yarn First 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.

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 teeth scissors glue markers 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 an
