World of Color for Smiley Faced Kindergarten

A class of Kindergartener's earned 100 smiley faces for good behavior and chose the science lab as their prize.  As a result, I got to see 28 smiley faces in my lab today!

Color is a physical property we can use to classify objects into groups.

Sometimes scientists have a hard time classifying things if they don't quite fit into categories.  Scientists put a platypus into the mammal category, but it has a bill and lays eggs!  We found objects like that as well.  How would you classify this?

The primary colors (needed to make all the other colors) are RED, BLUE, and YELLOW.  We did a little color mixing to test this out!

We set 3 primary colored water cups next to each other.

 

 

 We connected them with paper towels.

 

 The water absorbed through the paper towels.

 

 

We left them overnight and they mixed in the empty cups and formed purple and green!

 

We also created a glue color creation with watered down glue, food coloring and a stick dipped in soap.

 

Check out our creations!

 

Then we created secondary colors (green, orange and purple) from primary colors in our test tubes.

 

 

We also found that black contains all the colors, and....it is possible to separate them!

Black ink finger print on a coffee filter.  Dip the bottom in a little water and voilà, primary colors!

 

 

Separated colors on the coffee filter.

Lastly we talked about white light containing all the colors of the rainbow!  We used CD's, special glasses and bubbles to break up the white light into colors!

 

We took a picture through the glasses and this is what it looked like.
