1 Students know and understand common properties, forms and changes in matter and energy.
1 All matter is made of atoms, which are far too small to see directly through a light microscope. Elements have unique atoms and thus, unique properties. Atoms themselves are made of even smaller particles
a Identify evidence that suggests there is a fundamental building block of matter
b Use the particle model of matter to illustrate characteristics of different substances
c Develop an evidence based scientific explanation of the atomic model as the foundation for all chemistry
e Use tools to gather, view, analyze, and report results for scientific investigations about the relationships among mass, weight, volume, and density
2 Students know and understand the characteristics and structure of living things, the processes of life and how living things interact with each other and their environment.
1 Changes in environmental conditions can affect the survival of individual organisms, populations, and entire species
a Interpret and analyze data about changes in environmental conditions – such as climate change – and populations that support a claim describing why a specific population might be increasing or decreasing
b Develop, communicate, and justify an evidence-based explanation about how ecosystems interact with and impact the global environment
c Model equilibrium in an ecosystem, including basic inputs and outputs, to predict how a change to that ecosystem such as climate change might impact the organisms, populations, and species within it such as the removal of a top predator or introduction of a new species
d Examine, evaluate, question, and ethically use information from a variety of sources and media to investigate how environmental conditions affect the survival of individual organisms
2 Organisms interact with each other and their environment in various ways that create a flow of energy and cycling of matter in an ecosystem
a Develop, communicate, and justify an evidence-based explanation about why there generally are more producers than consumers in an ecosystem
