# Paddling in the North Woods

## Summer Fun!

This summer I paddle boarded in Three Lakes, Wisconsin. There is a large island with several boulders that I paddle boarded around. Throughout the summer, my dog and I paddle boarded by balancing on the board using one paddle. The view from the paddle board is outstanding. Paddle boarding is a fun and creative way to spend time outside in nature!

## The Science of it.....

When paddle boarding, the paddle creates a force to propel on the water. Newton's Second Law of Motion states that the amount of force on an object affects the speed of the object. The harder you pull, the faster you move on the water. Newton's Third Law of Motion is, for every action there is an equal or opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. Example- The first object is the paddle that pulls the water and the second object is the paddle board which is pushed into the direction of the pulling force.

## I wonder.....

1- I wonder how the water current would affect the paddle boards direction?

2- I wonder how the paddle size would affect the pulling force?

3- I wonder how the wind interacts with the paddle board and the force?

4- I wonder if the design of the paddle board would affect the way the paddle board moves?

5- I wonder if the person's arm length and strength would affect the speed of the paddle board?
