Energy of Objects

4th Grade

The speed of an object is related to the energy of an object.

• 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.

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

• Organize simple data sets to reveal patterns that suggest relationships.

• Describe, measure, estimate, and/or graph quantities (e.g., area, volume, weight, time) to address scientific and engineering questions and problems.

• Construct an explanation of observed relationships (e.g., the distribution of plants in the back yard).

• Use evidence (e.g., measurements, observations, patterns) to construct or support an explanation or design a solution to a problem.

• Identify the evidence that supports particular points in an explanation.

• Compare and refine arguments based on an evaluation of the evidence presented.

• Distinguish among facts, reasoned judgement based on research findings, and speculation in an explanation.

• Construct and/or support an argument with evidence, data, and/or a model.

• Use data to evaluate claims about cause and effect.

• Read and comprehend grade appropriate complex texts and/or other reliable media to summarize and obtain scientific and technical ideas and describe how they are supported by evidence.

• Combine information in written text with that contained in corresponding tables, diagrams, and/or charts to support the engagement in other scientific and/or engineering practices.

• Students learn matter is made of particles and energy can be transferred in various ways and between objects. Students observe the conservation of matter by tracking matter flows and cycles before and after processes and recognizing the total weight of substances does not change.

• 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.

• Moving objects contain energy. The faster the object moves, the more energy it has. Energy can be moved from place to place by moving objects, or through sound, light, or electrical currents. Energy can be converted from one form to another form.

When objects collide, contact forces transfer energy so as to change the objects' motions.
