Questioning and observing are skills needed for both science and for kindergarten readiness. Instead of using paper for coloring, cutting, and creating, here’s a fun activity that uses paper for dropping.
For this activity, two sheets of paper or notepaper are needed. Ask your child what might happen if you drop a sheet of paper. All kids know it will fall. Scrunch one piece of paper into a ball, Ask again what might happen if you drop it. 
Again, you will get the answer that it would fall. This time drop the paper ball. Your child was right, it did fall! Now try the sheet of paper. Did it fall the same? At this point, many kids open their eyes wide as they notice the paper floating.
Kids like to try this for themselves. Sometimes, they so like the floating instead of the dropping that they will uncrumple the paper ball and smooth out the sheet of paper so that it 
floats, too. Kids can try dropping the paper from a little stool, or off a step. They can add some colors to the paper to see as the paper floats. Older kids might want some help folding the paper into a paper airplane and trying that, as well. Isn’t it amazing that kids can enjoy all this science fun and learning from a simple activity with two pieces of paper?
