Several members of the East Carolina 4H Club that are way into entomology came out to discuss the order Orthoptera with the Explorers. After discussing what makes crickets, grasshoppers and katydids unique, they started the jumping experiment. The experiment was to compare the jumping ability of the cricket to humans (students). Supplies needed for this experiment:
First, the length of the cricket was measured (2 cm) and then the length of the cricket's jump was measured (5cm). Next, each of the students took a turn jumping (standing broad jump style) and the length of their jump was recorded. Then, the height of each of the students was measured. Finally, to determine the jump to size ratio, the jump was divided by the participant's height/length. As the chart above shows, the cricket was the best jumper. It jumped 2.5 times its size. The closest student jumped 1.23 times their size. While we had researched that insects in the order Orthoptera can jump up to 20 times their size, we were quite impressed by the 2.5 times that our specimen jumped. After the ratios had been calculated and discussed, the students participated in a cricket jumping race. While most of the crickets preferred jumping in the opposite direction of where the students were trying to coach them to jump, we did have a couple that went for gold. Explorers planted the following in the two raised beds:
The differences between annual and perrenial plants were discussed. And how to properly plant the plants was demonstrated. The Explorers had a great time planting and tending to the new butterfly garden. |
