Off the Rails (2nd-3rd)

Forces and Motion

Grades 2-3

Patterns in motion can be observed and measured to predict future motion.

• Represent data in tables and/or various graphical displays (bar graphs, pictographs and/or pie charts) to reveal patterns that indicate relationships.

• Analyze and interpret data to make sense of phenomena, using logical reasoning, mathematics, and/or computation.

• Use data to evaluate and refine design solutions.

• Make observations and/or measurements to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution.

• Make predictions about what would happen if a variable changes.

• Test two different models of the same proposed object, tool, or process to determine which better meets criteria for success.

• They identify patterns related to time, including simple rates of change and cycles, and to use these patterns to make predictions.

• Students routinely identify and test causal relationships and use these relationships to explain change. They understand events that occur together with regularity might or might not signify a cause and effect relationship.

• Students understand objects and organisms can be described in terms of their parts; and systems in the natural and designed world have parts that work together.

• The effect of unbalanced forces on an object results in a change of motion. Patterns of motion can be used to predict future motion. Some forces act through contact, some forces act even when the objects are not in contact. The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center.
