I thought I'd share them, in case anyone else is in need of some princess science ideas.
And to prove that you can connect science to anything!
I didn't get any shots while the girls were in action - we were too busy having fun to worry about the camera, but I can give you an idea what we did.
First, we did some Princess Potions
The girls each had a "place mat" like the one shown above. In the large circle there was a cup that contained some red cabbage juice. There were smaller cups sitting in spots A, B and C. Cup A contained some baking soda dissolved in water, Cup B contained vinegar and Cup C contained water.
Each girl selected one of the smaller cups (A, B or C) and poured it into the large cup. If the potion turned pink, she earned her tiara. If the potion turned green, she had to kiss a frog and try again. If the potion stayed blue/purple she had to try again.
Next up was the Magic Paper:
The girls kept the A, B and C cups from above. They were each given a piece of "magic" paper - goldenrod paper. They needed to unlock the paper's magical powers. They dipped a q-tip into one of the solutions (A, B or C) and then attempted to write on the paper. Choosing the right solution would result in red marks on the paper and earn the princesses a candy bracelet.
This was a race to see who could make a cup of "tea" the fastest - i.e. who could dissolve a sugar cube the fastest.
The girls were each given a menu:
After they made their selections, we raced. Completion of the task earned the girls a new wand.
And finally, to complete the whole princess ensemble, the girls made shirts using the pinwheel chromatography method (i.e. Sharpies and rubbing alcohol). Lots of fun and creative designs.
