In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution. Learners soak one regular hard-boiled egg and one peeled hard-boiled egg in dyed water and then record how the eggs' circumference and appearance change after 24 hours. Learners investigate how the peeled egg represents amphibian skin and how amphibians are affected by pollution.
