agree on both

The scientific method is a systematic approach used to answer scientific questions. In the given scenario, Rick wants to investigate the relationship between rising carbon dioxide levels and global temperature.

The step of the scientific method that applies to this scenario is "Make a hypothesis."

A hypothesis is an educated guess or an assumption that can be tested to determine its validity. In this case, Rick's hypothesis could be that increasing carbon dioxide levels in the atmosphere have an impact on global temperature. This hypothesis is based on prior knowledge and observations of the greenhouse effect, which suggests that high levels of carbon dioxide can contribute to global warming.

To test this hypothesis, Rick would need to gather data and conduct experiments to see if there is a correlation between rising carbon dioxide levels and changes in global temperature. This could involve analyzing historical data, monitoring current atmospheric conditions, or conducting climate simulations.

Once the hypothesis is tested through experiments and data analysis, Rick will be able to draw conclusions about the relationship between carbon dioxide levels and global temperature. These conclusions will help contribute to scientific knowledge and can be used to inform future studies and decision-making regarding climate change.
