Physical Science Introduction to Scientific Inquiry Background Scientific inquiry is a process scientists use to study the natural world in order to answer questions or solve problems. It consists of several steps including asking questions, conducting research, forming hypotheses, conducting experiments, collecting and analyzing data, drawing conclusions, and communicating experimental results to others. In today’s activity, you will follow some steps of the scientific inquiry process as you investigate a natural phenomenon known as Charles’ Law. Introduction 1. Posing Questions Have you ever observed what happens to a sports ball when it is left in the sun all day, or left outside overnight? What questions could you ask about how a change in…show more content…
What is the manipulated variable in your experiment? Putting the ball in a cold freezer. c. What is the responding variable in your experiment? The gas pressure change inside the ball in the freezer. 4. Collecting and Analyzing Data There are two types of observations: qualitative and quantitative. Qualitative observations use words to describe what is observed during the experiment. These notes are kept in a journal or logbook. Quantitative observations use numbers, such as calculations and measurements that are recorded in data tables. Scientists around the world use the same system of measurement called the metric system. In your experiment the unit for volume is cubic meters (m3). The unit for temperature is Kelvin (K). Ball A is in room temperature at 600k. While ball B is in a freezer 273k. Both balls started with about 455.9cm^3. Ball B seem to have lost a volume. Analyze and Conclude 1. Communicating (Qualitative Data) Your written observations about what happened in the experiment is qualitative data. Write a short summary of what you observed. I've learned that the temperature can cause the deflation of the ball. The colder the temperature is the more the ball volume will go
