What's A Peeling?

Gan Gimmel has been learning about etrogim. The etrog is a citrus fruit. We examined various citrus fruits such as oranges, grapefruits, lemons and limes and compared and sorted them according to size, shape and color.

The children were excited to perform several experiments with oranges, a citrus fruit. We placed an orange in a container of water and it floated. When we peeled the orange and placed it into the container the children were surpised to see it sink. The peel floated when placed in the water. Zaviel deduced that the orange peel contains a lot of air and therefore is lighter than the water. . The fruit of the orange is heavier than the water so it sinks. We then wrapped the peel back around the fruit and when put into the water, the orange floated again.

We loved doing the experiments and can't wait to taste the citrus fruits.

Does an etrog float? Try it at home.
