Grasshoppers Sniffing Out the Case

Ashton B, Johnathan F, Kylie S, Jack K

We observed the food choices of grasshoppers.  We were looking for the preferred food from a selection of geranium. marigold, grass, and lemon balm.  Our group predicted that the hoppers would prefer the lemon balm because of the strong scent.  We put the picked leaves near opposite walls of a square box and waeched to see where the grasshoppers went.  The large grasshoppers consistently preferred the marigolds.  The smaller grasshoppers were very actiive but did not choose to be near food.
