Exploring Physical Science Chapter 1 Section 1

Physical Science The study of matter and energy – Matter-anything that has mass and takes up space Pencil Shoes Air – Energy- the ability to do work All matter has energy Responsible for rainbows, but is not the rainbow

Physical Science 2 categories – Chemistry-study of all forms of matter and how the interact Why yeast makes bread dough rise Why sugar dissolves faster in hot tea than in iced tea – Physics-study of forms of energy and how it affects matter Why you see a rainbow after a rainstorm How a compass works

Role of Physical Science in other Sciences Astronomy- – explain composition of planets, – Light given off by stars Meteorology – Movement of air masses – Composition of atmosphere Botany – Explain how plants use carbon dioxide and water to make food Geology – Explain earthquake waves – Rock composition

Role of Physical Science in other Sciences Oceanography – Explain waves – Explain currents Ecology – Explain nitrogen cycle – Explain transfer of energy between organisms in a food chain Biology – Explain how the heart pumps blood – How the eyes and ears work

Careers That Rely on Physical Science Auto mechanic – How engine parts move Chef – How ingredients interact Chemist – How substances can be made into products
