[2.PS.3.1] - Design and conduct an experiment to show the effects of friction on the relative temperature and speed of objects that rub against each other. Clarification Statements: Examples could include an object sliding on rough vs. smooth surfaces; Observations of temperature and speed should be qualitative.

Predecessor Standards:

  • 1.MD.C.4
    Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

Successor Standards:

  • 3.PS.2.1
    Provide evidence to explain the effect of multiple forces, including friction, on an object. Include balanced forces that do not change the motion of the object and unbalanced forces that do change the motion of the object. Clarification Statements: Descriptions of force magnitude should be qualitative and relative; Force due to gravity is appropriate but only as a force that pulls objects down; State Assessment Boundaries: Quantitative force magnitude is not expected in state assessment; State assessment will be limited to one variable at a time: number, size, or direction of forces.

Same Level Standards:

  • W.2.2
    Write informative/explanatory texts that introduce a topic, use facts and definitions to develop points, and provide a concluding statement or section.
  • SL.2.5
    Create audio recordings of stories or poems; add drawings or other visual displays to stories or descriptions of experiences when appropriate to clarify ideas, thoughts, and feelings.
  • 2.MD.D.9
    Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Organize and record the data on a line plot (dot plot) where the horizontal scale is marked off in whole-number units.
  • 2.MD.D.10
    Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph. See Glossary, Table 1
