Mega Strength... or Science

This science experiment was great for our super hero week and it was part of the lesson I found at education.com 

To set my heroes up for this activity I talked up Jerry and his strength.  
He put his fists together, one on top of the other and pressed them together. 
I told the kids there is no way anybody could get his hands apart because he his very strong.
For an example I tried to separate his hands and couldn't get them apart. 
(I did this on purpose for effect. I tried pulling up.)

Then the heroes tried. 
 They put their finger tips on the sides of his hands and pushed his fists horizontally. 
And his hands came apart! 


Why it works: science! 

There are two forces in play here, horizontal and vertical.  When pressing your fists together you are applying vertical force.  You are unable to apply both horizontal and vertical forces at the same time, therefore when a horizontal force is applied the hands come apart easily.  Making it seem like the kids are really strong. 

This experiment must be done with the elbows close to the body, not with the arms at a 90 degree angle. 

The Dragons and Jerry did this experiment over and over again testing out their super powers!

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 blac...

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 ...

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.        ...
