 Scientific Research: Standard 3 - Investigate Checks for Understanding 3.1 | 3.2 | 3.3 | 3.4 | 3.5 | 3.6 | 3.7 | 3.8 | 3.9 | 3.10 | 3.11 Science Curriculum Standards 3295 - Scientific Research Internet Resources Develop a testable question for a scientific investigation. 3.1 Differentiate between variables and controls in an experiment and select appropriate variables for an experiment. 3.2 Conducting a Scientific Investigation - a two part lesson plan - Part 2 of the lesson plan Doing Science: The Process of Scientific Inquiry - a web based lesson plan from the National Institutes of Health How Science works: Types of Variables - Explains the difference between 'categoric', 'ordered', 'discrete' and 'continuous' variables, with examples. How Science works: Variables - Explains the meaning of 'independent', 'dependent' and 'control' variables, with examples from typical practicals. Identify the Controls and Variables - worksheet to print and use in class [the author of this activity probably violated copyright by using Simpson's characters, but you will not be guilty if you use it in class] Develop an experimental design with proper application of controls and variables for testing a hypothesis. 3.3 Perform an experiment to test a prediction. 3.4 Basic format of any hypothesis test - from Skills4Study Conducting a Scientific Investigation - a two part lesson plan - Part 2 of the lesson plan Designing Science Experiments - from Crystal Clear Science Fair Projects Doing Science: The Process of Scientific Inquiry - a web based lesson plan from the National Institutes of Health Experiment - Wikipedia entry How to Use the Scientific Method to Test a Hypothesis - six steps are listed How Science works: Types of Variables - Explains the difference between 'categoric', 'ordered', 'discrete' and 'continuous' variables, with examples. How Science works: Variables - Explains the meaning of 'independent', 'dependent' and 'control' variables, with examples from typical practicals Hypothesis Test - from Cool Science Projects.com Hypothesis test 1: an experiment on telepathy - used as an example of the process Hypothesis test 2: the shuffle test - using statistical analysis Identify the Controls and Variables - worksheet to print and use in class [the author of this activity probably violated copyright by using Simpson's characters, but you will not be guilty if you use it in class] Practicing Scientific Processes - from Glencoe Science Statistical hypothesis testing - Wikipedia entry Student Design of Drop Bounce Experiment - Test Your Hypothesis - from Lane Libraries Science Fair Zone Design and use appropriate procedures for laboratory and fieldwork. 3.5 Apply appropriate safety guidelines. 3.6 Make correct use of scientific materials. 3.7 Demonstrate appropriate measurement techniques. 3.8 British and Metric Conversions - a series of pages relating to converting to or from metric units Calculating the Density of a Liquid - tutorial on the math involved plus sample questions Calculating Density of a Solid - tutorial on the math involved plus sample questions Converting Fahrenheit to Celsius - interactive problem from Annenberg Converting Length Measurements - use your knowledge of meters, centimeters and millimeters to answer questions to build a shed Finding the Mass of an Object - tutorial on using a triple-beam balance which includes questions to answer Finding the Volume of an Object - tutorial on using a graduated cylinder which includes questions to answer Platform Scales Addition - weigh several items and find the sum in hundredths of a gram or Platform Scales Subtraction - weigh several items and find the difference in hundredths of a gram or Teaching Measures - links to length, mass, or capacity activities and printables - good for using on an interactive whiteboard for a whole class activity Transparency Master - use this high quality picture of a block of metal on a triple beam balance as a review for your students Using a Graduated Cylinder - [L and mL] a whole class activity for reading a scale, estimating and converting between units or Using a Platform Scale - practice using scales like the one in a doctor's office, five Gregs will drop on the scale, waiting to be weighed, see how quickly you can weigh them or Using a Ruler - a whole class activity for reading a ruler, estimating and converting between units or Maintain a well-documented project journal. 3.9 Modify or design an alternative experimental procedure to test a hypothesis. 3.10 Apply established procedures to novel situations. 3.11
