1.1 Science in Context – We learned how scientists share their findings and why peer review of these findings is so important. We reviewed the difference between scientific theory and scientific law.
1.3 Studying Life – We continued to discover the big ideas of biological study. We explored homeostasis, evolution, structure and function, unity and diversity of life. Next, we learned about the interdependence in nature and science as a way of knowing.
What is BPA? We learned that BPA stands for bisphenol A, which is an industrial chemical that has been used to make plastics and resins since the 1950s. This epoxy resin is used to coat the inside of metal products containing food, bottle tops, and water supply lines. Research shows that BPA can seep into food and beverages. BPA has been linked to cardiovascular disease, type II diabetes, and increased blood pressure. Exposure to BPA is a concern because of its effects on the brain, prostate gland of fetuses, infants, and children. We learned what type of plastics to avoid and how to prevent the leaching of this chemical into containers.
