E.S. 1 Experimental Design and Measurement

Master scientific tools and experimental design!

Tools, Scientific Method, Properties of Matter Match the words to the correct definitions. Graduated cylinder A tool used to measure the volume of a liquid or an irregularly shaped object. Triple Beam balance A tool used to find the mass of an object. Hypothesis An idea that can be tested by an experiment or an observation. Density Mass divided by volume mass the amount of matter in an object volume the amount of space an object takes up What is the amount of matter in an object or substance? matter relative density mass What is the amount of mass in an object? It determines whether an object sinks or floats. matter density solubility What is an instrument used for viewing very small objects such as mineral samples or animal or plant cells? telescope graduated cylinder microscope What is a simple container for stirring, mixing or heating liquids? beaker thermometer graduated cylinder What is an instrument for measuring and indicating temperature? thermometer hand lens hot plate What is a tool used to measure weight (force) by balancing the force due to gravity against the force on a spring> triple beam balance spring scale scale What is a magnifying glass with a convex lens that is used to produce a magnified image of an object? hand lens microscope telescope What is a measuring stick one meter long that is marked off in centimeters or millimeters? ruler yard stick meter stick What is a flat heated surface typically portable used for cooking food or keeping it hot? microwave hot plate fire What is something used for making mathematical calculations? calculator Rubiks cube ruler Determine if each part of the sentence has to do with the IV or the DV. Fill it in as you go. An IV is the variable that is changed or controlled in a scientific experiment to test the effects on the DV. A IV is the variable being tested and the DV is measured in a scientific experiment.The DVis 'dependent' on IV. As the experimenter changes the IV, the effect on the DV is observed and recorded.If the IV is changed, then an effect is seen in the DV.When results are plotted in graphs, the convention is to use the IV as the x-axis and the DV as the y-axis. What is the SI unit for each of the following? mass grams volume cubic centimeters or liters length meters weight newtons Metric Conversions Convert the following. Write in your answers for each. .005 700 .00006 2500 .000045 770 3700 .02 .044 88000
