Intro to Science and Chemical Reactions Essential for Life Unit Overview
(chapters 1.1-1.4,2.1-2.5,3.1-3.2, 4.1-4.2, 4.4,4.6)
Biology is the study of life. We will be exploring living things by asking meaningful questions and
conducting investigations. We’ll review the basics of chemistry as it applies to the chemical
reactions necessary for life.
NEXT GENERATION SCIENCE STANDARDS
HS-LS1-6 Construct and revise an explanation based on evidence for how carbon, hydrogen, and
oxygen from sugar molecules may combine with other elements to form amino acids and/or other
large carbon-based molecules.
HS-LS1-7 Use a model to illustrate that cellular respiration is a chemical process whereby the bonds
of food molecules and oxygen molecules are broken and the bonds in new compounds are formed
resulting in a net transfer of energy
HS-LS1-5 Use a model to illustrate how photosynthesis transforms light energy into stored chemical
energy.
HS-LS2-5 Develop a model to illustrate the role of photosynthesis and cellular respiration in the
cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.
