For my STEAM project I used sea glass, rocks, and markers to explain how chemicals can mimic or interfere with our body’s natural hormones. These chemicals are known as endocrine disrupting chemicals. They can be natural or man-made. We can be exposed to them through the food we eat, beverages we drink, air we breathe, and things our skin comes into contact with. Endocrine disruptors have been linked to reproductive problems, thyroid issues, developmental abnormalities, cognitive issues, and more.
