Compare the life cycles of different plants including germination, maturity, reproduction and death.
Describe how organisms interact with one another in various ways (e.g., many plants depend on animals for carrying pollen or dispersing seeds).
Relate plant structures to their specific functions (e.g., growth, survival and reproduction).
Classify common plants according to their characteristics (e.g., tree leaves, flowers, seeds, roots, stems).
Observe and explore that fossils provide evidence about plants that lived long ago and the nature of the environment at that time.
Identify characteristics of a simple physical change (e.g., heating or cooling can change water from one state to another and the change is reversible).
Identify characteristics of a simple chemical change. When a new material is made by combining two or more materials, it has chemical properties that are different from the original materials (e.g., burning paper, vinegar and baking soda).
Describe objects by the properties of the materials from which they are made and that these properties can be used to separate or sort a group of objects (e.g., paper, glass, plastic, metal).
Explain that matter has different states (e.g., solid, liquid and gas) and that each state has distinct physical properties.
Compare ways the temperature of an object can be changed (e.g., rubbing, heating, bending of metal).
Analyze a series of events and/or simple daily or seasonal cycles, describe the patterns and infer the next likely occurrence.
Develop, design and conduct safe, simple investigations or experiments to answer questions.
Explain the importance of keeping conditions the same in an experiment.
Describe how comparisons may not be fair when some conditions are not kept the same between experiments.
Formulate instructions and communicate data in a manner that allows others to understand and repeat an investigation or experiment.
