  • Major Quiz 8-1.1 Technological DesignObjective(s) The Learner Will Be Able To:variable at a time; recognize steps appropriate for conducting a controlled investigation; detect inappropriate steps in a given investigation; organize the results of the investigation in tables or charts; classify by sequencing the steps of a controlled scientific investigation; or summarize the steps in a controlled scientific investigation.TLWBAT (8-1.4) construct questions that can be tested with an investigation related to a prior investigation; exemplify questions that can be tested through scientific investigations;TLWBAT (8-1.5) construct a cause-and-effect model showing the importance of repeated trials to detect patterns and trends in data; summarize reasons why the results of an investigation may produce different results; recall the importance of replication; identify conditions necessary to collect valid data; or exemplify valid investigations.Material(s): 
  • Metric ruler, Triple beam balance, Calculator, United Streaming, M&Ms, Graphs, Charts, Tennis Balls, Racket Balls, Meter Tapes, Meter Sticks, Antacid Tablets, Graduated Cylinder, Cup, Water, Calculator, Vinyl Record, 8 Track Tape, Cassette Tape, CD, iPod, Bubble Map, Jump Drive
  • critique a conclusion; identify the experimental variables in the investigation to determine a new investigation design; compare the results of one investigation with a question for further study; explain the relationship between the independent and dependent variable to determine questions for further investigation; or identify questions that are appropriate for previously generated conclusions.
  • TLWBAT (8-1.3) produce an explanation or conclusion for an investigation: interpret and analyze data collected in an investigation; recognize a valid conclusion for a given investigation; compare a conclusion to the appropriate investigation; compare the conclusion with a given hypothesis; or select an appropriate conclusion for a given investigation.
  • TLWBAT (8-1.1) devise a plan for conducting a science investigation that tests only one


Topic:    Density and Graphing


8.S.1A.3   Plan and conduct controlled scientific investigations to answer questions, test hypotheses, and develop explanations: (1) formulate scientific questions and testable hypotheses, (2) identify materials, procedures, and variables, (3) select and use appropriate tools or instruments to collect qualitative and quantitative data, and (4) record and represent data in an appropriate form. Use appropriate safety procedures.
