Bug-eyed Adventures: Discovering Insect Defense Mechanisms Through Hands-On Learning

A group of 20 enthusiastic youths gathered at a 4-H day camp in Worthington to learn about insect defense mechanisms. Led by Minnesota West biology professor Heidi Tarus, the children embarked on a science-filled morning to explore the fascinating world of insects.

Armed with bug nets and petri dishes, the young scientists ventured outside to the Minnesota West pollinator plots. Using sweep nets, they discovered a diverse array of insects residing in the plot, including mosquitoes, dragonflies, spiders, and more. Back in the biology lab, they examined their collected specimens under a microscope and marveled at their intricate exoskeletons.

To wrap up the day camp, the children were tasked with constructing an exoskeleton model that could safeguard a model bug. Using materials such as cardboard, bubble wrap, and egg cartons, they crafted protective models that withstood the weight of 10 heavy biology books. Many of the models proved to be incredibly sturdy and effective in shielding their bugs from harm.

The camp was expertly led by Minnesota West Biology and Natural Science Instructor Heidi Tarus and Nobles County 4-H Extension Educator Anna Rose. The children engaged in hands-on activities and experiments to deepen their understanding of insects and their protective mechanisms. Through this immersive learning experience, these young scientists gained a newfound appreciation for the incredible adaptations that allow insects to thrive in our world.
