I Can Statements For UNIT 1

Chapter 1

• I can define physical science as the study of matter and energy.

• I can describe the components of a good controlled experiment.

• I can define terms associated with controlled experiments (independent variable, dependent variable, constants, and control).

• I can read about a scientific experiment and determine the independent variable, dependent variable, constants, and control.

• I can interpret data on a scientific graph and describe data trends using proper terms (e.g. linear, nonlinear, directly proportional, inversely proportional, direct relationship, and inverse relationship).

• I can use SI units to measure length, mass, and volume.

• I can use a standard science reference sheet to find SI units and equations for calculating things such as volume or density.

• I can convert between units in the metric system (e.g. cm à km) using the goal-post method.

• I can calculate the density of a substance or object.

Chapter 2

• I can describe the difference between physical and chemical properties.

• I can describe the difference between physical and chemical changes.

• I can interpret a data table of common physical properties (e.g. density, melting / boiling point, malleability) and chemical properties (reactivity, flammability, corrosivity).

• I can differentiate between elements, compounds and mixtures based on their composition and understanding how they can or cannot be separated.

• I can describe different methods for separating mixtures including filtering, centrifuge, and distillation.

Chapter 3

• I can describe the 4 states of matter in terms of KMT (the energy of the particles and the force of attraction between those particles).

• I can predict how changes in volume, mass, and temperature affect the pressure of a gas.

• I can describe the 6 changes of state (melting, sublimation, vaporization, condensation, deposition, and freezing) in terms of what happens to the energy and spacing of the particles.

• I can describe the differences between endothermic and exothermic changes of state.

• I can find the melting and boiling points on a change of state graph.

• I can determine portions of a change of state graph that represent solid, liquid, and gas.
