 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 � Internet4classrooms is a collaborative effort by Susan Brooks and Bill Byles.
