Chemistry is the study of matter. So how does one study matter, you may ask? One studies matter by following the “Scientific Method”. In a more general sense, we can observe matter how it behaves by making observations, hypothesizing, doing experiments and making conclusions through our observations and experimentation. Below is a video about Dry Ice.
After watching this video, you will answer some questions. You may not know all the answers, and PLEASE, do NOT google the answers to these questions. This is an exploration of your mind only. From your experiences of previous classes and your own intuition, what do you observe? Try to think like a chemist. Use your mind from common knowledge of things that you have learned in previous classes and your own life experiences. Please be honest!
Think in terms of matter and its physical and chemical changes. The video will show 10 different demonstrations when using dry ice. Try answering these questions.
(Note: Physical Change – matter that has specific characteristics and changes its form. Chemical change – matter that changes its chemical composition resulting from chemical reaction and its identity is changed.)
