Today we learned what dehydrating means and why it was used to preserve food in the past.

We used a crank apple corer/slicer to prepare apples for dehydration. 

The apples were spread on a tray on the food dehydrator. 

It takes about 15 hours until the fruit is ready to eat so I had strawberries, apples, and banana chips that I had already dried for the students to try.  We compared the fresh apples to the dried ones and about half of the group preferred the dried apples.

I also purchased some dried vegetables but they were not a big hit. :-)

We had some time leftover so each child chose a Lego challenge card and used Legos to complete the challenge.
