Climate Change Virtual Laboratory
Introduction Global warming has become a huge controversial topic over the last several years. Some believe in it, some do not. Climate change also is another controversial topic. Global warming is the gradual increase of the earth’s surface. Climate change is the long-term in our weather patterns (USGS, n.d.). Understanding the impacts and the differences can help us learn on how we can make changes to protect our planet, which is why this lab was so important. The demonstrations in the virtual lab provided us with the results the impact our planet will have over periods of time. For activity 1, my hypothesis was that the Earth with the atmosphere would be warmer than that of Earth without an atmosphere. The reasoning behind this was for the greenhouse gases that would be present. Activity 2, my hypothesis was that the ocean ice would be warmer than the Arctic Sea ice. My reasoning behind this prediction was that the Arctic Sea is already much cooler. Lastly, activity 3, my hypothesis was that the island with the glacial ice would have a lower sea level than that of the island with sea ice. My reasoning was that glacier ice is bigger causing it to take longer to melt. Results

Graphs and Photographs
Activity 1: Average Surface Temperature of Earth vs. Time
– Based on the above graph it shows the Earth with atmoshere has higher temperatures over a 1,000 year period.

Activity 2: Average Temperature of Ocean or Sea Ice vs. Time
- Based on the above it shows the Open Ocean has higher temperatures.

Activity 3: Difference in Sea Level Elevation After Ice Melt
– Based on the above results, the island with melted Glaceier ice had a higher sea level.
Analysis
My hypothesis for activity 1 was that the Earth with an atmosphere would be warmer over a 1,000-year period compared to Earth two that did not have an atmosphere. The results showed that the Earth with the atmosphere was significantly warmer than that of the second Earth. Based
on the results I would accept my hypothesis. Based on the evidence, my hypothesis was correct. For activity 2, my hypothesis was that the ocean ice would be warmer than that of the Arctic Sea ice. The reasoning behind this was the Arctic Sea is already much cooler than the ocean. I accepted my hypotheses, and this was because it was correct. Arctic ice is lighter which is more reflective. The ocean is darker and retains more heat.

For the last activity, number 3, my hypothesis was that the glacial ice would not melt as fast causing the island with the sea ice would have a higher sea level. My reasoning behind this was that glaciers are much bigger thinking it would take longer to melt. I would reject my hypothesis since I was incorrect. This is because the combination of warmer water and air combination, it caused the glacier ice to melt quicker causing a higher sea level. Discussion
The results of this lab have opened my eyes more for the need to make global warming and climate changes more heard. I also need to promote this more by making daily changes in my household. One way is to limit carbon pollution and move towards cleaner energy sources (Denchak, 2023). Some simple things that can take place to help make some of these changes is to lower non-renewable energy consumption by doing simple things around your house like replacing weather stripping around doors and windows, installing energy efficient appliances, reducing water waste, and eating food we buy preventing less waste (Denchak, 2023).
I would not say I had any mistakes this week. However, the virtual lab did freeze on me so I had to start over since I was not real sure where it would resume. This happened twice to me. The only mistake I would say I made was in activity 3, predicting incorrectly. I had to go back to read
more on the subject to understand better the why the glacier ice would have melted faster than the sea ice. References
