Apples and Handwashing: "We put a clean apple slice in one jar. We passed another apple slice around the class as we came in from recess with dirty hands. We have been observing the two jars in the science center. This is the difference after 8 days - gross! (This picture doesn't really show the mold.)" - A great way to teach about germs.
Building with apples. good idea! much better than marshmallows. Kids can eat a healthy apple snack while building neat structures. Knowing me, I will toss in a handful of sticky marshmallows for good measure.
