Some might view Mommy and Daddy as packrats. They have a lot of scrap from house and craft projects. They're not fans of throwing out things (especially if money was spent) in case they might find a creative use. But Mommy CAN bring herself to do it. Before purging, though, Mommy has to consider one last time how something might be used.
On this particular day, Mommy, Vanessa and Zane had a lot of fun creating tunnels and ramps with leftover pipe. They learned about inclines and declines and diameter. They practiced ordering things from smallest to largest. They explored time and speed. They tested cause and effect by positioning pipe along and above other forms of ramps and planes.
The spontaneous learning was enjoyable, even with Zane and Vanessa scrapping over the implementation of ideas.
