3. Introduction to Science Chapter 3.1 Exploring Physical science

4. Objectives: Explainthat science involves asking questions. Describe the relationship of matter and energy to physical science. Describe the two branches of physical science. Identifythree areas of science that use physical science.

5. That’s Science! Science Process of gathering knowledge about the natural world. Everyday Science Learning to do everyday actions requires: making observations and asking questions, which is what science is all about.

6. Physical science study of matter and energy Matter is the “stuff” everything is made of. Energyis the ability to do work. What is Physical Science?

7. A Study of Matter and Energy Learning about matter and energy will help you answer questions such as: Why will paper burn and gold will not? Why is throwing a bowling ball harder than throwing a baseball? How can water turn into steam and back into water?

8. Branches of Physical Science: Physical science is usually divided into: Chemistry––A Matter of Reactions! The study of all forms of matter, including how matter interacts with matter. Physics––A Matter of Energy! Looks mostly at energy and the way that energy affects matter.

9. Other related sciences: Meteorology The study of the Earth’s atmosphere, especially in relation to weather and climate, is called meteorology. Meteorologists must understand high and low pressure, motion, and force before the can predict the weather.

10. Geology The study of the origin, history, and structure of Earth. Geochemist are geologists who apply their knowledge of heat, force, and chemistry to understand how rocks and soil change over time.

11. Biology The study of life. Chemistry and physics explain many things that happen in biology. A chemical reaction explains how animals use sugar and oxygen to produce carbon dioxide and water and to release energy.
