Core Skills Analysis
Science
Tony planned and carried out a fair comparison of differently sized and shaped bouncy balls by testing their elasticity on both a hard floor and carpet. By changing the surface and repeating the experiment, Tony learned that results depended on the testing conditions: the balls that performed best on the hard floor were not necessarily the best on carpet. Tony also identified one ball that performed well on both surfaces, demonstrating how repeated tests can reveal patterns as well as differences.
Mathematics and Data Skills
Tony organized and ranked the balls’ results, turning observations from the two surface tests into comparisons. Tony learned to interpret rankings in context: a ball’s position could change when the testing surface changed, so a result from one condition did not automatically predict performance in another. Comparing the two sets of outcomes helped Tony notice which ball performed well across both conditions.
Language Arts and Scientific Communication
Tony’s experiment involved communicating a testable question through a planned procedure and organizing the resulting observations. Tony distinguished between findings for the hard floor and findings for the carpet, then recognized that the outcomes were not identical across conditions. This activity supported clear scientific explanation by connecting the procedure—testing balls on different surfaces—to the conclusion that surface affected which balls ranked highest.
Tips
Tips Extend Tony’s investigation by having the child agree on a consistent way to measure each bounce, then repeat trials and record the results in a table. Invite Tony to create a bar graph comparing each ball’s results on the two surfaces and explain what patterns the graph shows. Try another surface or a new set of balls, changing one condition at a time so the effect of that change is easier to interpret. To connect science with communication, have Tony write a short experiment report with the question, procedure, results, and evidence-based conclusion.

Learning Standards
- RST.6-8.3: Tony followed a planned, repeated experimental procedure while changing the test surface.
- RST.6-8.7: Organizing and ranking results created an opportunity to connect written observations with a visual table or graph.
- RST.6-8.8: Tony’s conclusions were grounded in observed test results, including the difference between surface conditions.
- WHST.6-8.2: A written report of the experiment can explain the procedure, findings, and conclusion using relevant details.
- 6.SP.A.2 and 6.SP.B.5: Comparing and summarizing results across the two surfaces aligns with describing data patterns in context.
- SL.6.4: Presenting the findings with a logical sequence and details would communicate Tony’s results clearly.
