Science Methods II

 We started this lab discussing our interview with elders about climate change We next read a climate change article and the questions that goes with it are: 1. how bad is climate change now  2. How do scientists know 3. who is influencing key decisions 4. how do we stop fossil fuel emissions  5. Do environmental rules matter 6. Can insurance protect us 7. Is what I do important Green house effect: A greenhouse gas is a gas that absorbs and re-emits infrared light Molecules vibrate with infrared light but not all of them do  Every molecule lets visible light through

 April 18th We started today's class discussion our exam last week. After that we start talking about climate change which is a huge topic in today's world. We looked at a "hot" days chart for Des Moines. The chart is proves that more and more days are getting hotter which means most days in the future are going to be over 90 degrees. Iowa has millions of acres of land to grow corn which is huge but due to climate change how damaging is it? Due to the climate change (the rise in hotter days and more precipitation) means the Iowa agriculture will hurt from it. because of this change Iowa is adapting to many of these changes such as: wetter season, longer growing season, more summer precipitation, and higher humidity, and the fall will become dryer) Driving Question: How does climate change affect sea level? One of the major drivers of the SLR the world has experienced in recent decades is not from melting glaciers or ice sheets. Rather, it is driven by the  thermal exp...

 Lab: Looking at sand through a microscope (Excused absence from class) Archimedes Law: W(air)/(W(air)-W(water)) 1. Sand in water Characteristics: - Colors: Brown, Green, White, and Clear - Size: Varying sizes - Appearance: Shiny 2. Dessert - Colors: Pink, Tan, Gray, White, and Orange - Size: Similar Size Appearance: Very nice to look at! Looks like Himalayan Salt 3. Volcano - Colors: Brown and Black - Size: Most are about the same size some pieces are bigger than others - Appearance: Pieces reflect the light 4. Beach Sand - Colors: White, Pink, and Clear - Size: Different sizes - Appearance: Sizes vary 5. Hawaii Sand - Colors: Clear, White, Black, Brown, and Green - Size: Sizes vary - Appearance: Speckled 6. Sand with Rock in it - Color: Orange, Pink, and White - Size: Similar Sizes - Appearance: Very textured and round. The rock looks like many sand pieces smashed together Characteristics of Sand: Sand and water- polished, smooth, and similar size Sand and glaciers- polished, sm...
