Which of the following are testable using scientific experimentation? a. Are there more seeds in a medium sized Red Delicious Apple or a medium size Green Granny Smith Apple? Yes b. Why do people smoke cigarettes? Nicotine is the really drug in tobacco. Nicotine is a medication that influences many pieces of your body, including your mind. Over the long haul, your organic and cerebrum become accustomed to getting nicotine in them. Nicotine arrives at your mind and makes the cerebrum discharge adrenaline. c.

It's the second largest planet and there's a lot to investigate. It has 62 moons that make it special compared to other planets. e. Which objects are attracted by a magnet: a metal paperclip, copper penny, or aluminum foil? Magnets are simply drawn to exceptional metals. Iron, cobalt and nickel are attractive. Metals that have iron in them draw in magnets well. Steel is one. Metals like metal, copper, zinc and aluminum are not drawn to magnets. Thus, copper penny and aluminum foil are not right. Might be the metal paperclip if its comprised of attractive material lOMoARcPSD|3013804 Lab 2 The Scientific Method CHEM101L 2. For each of the following questions, write a reasonable hypothesis using the “If (independent variable), then (dependent variable)” format. a. Does water affect the growth of a plant? If water influences the development of a plant then the plant ought to develop more subsequent to watering it. b. Does temperature affect the amount of sugar that dissolves into tea? If temperature influences the measure of sugar that breaks up into tea then at the point when tea is colder sugar takes more time to completely vanish and disintegrate Click here to enter text.. c. Does the volume of a container affect how quickly water will evaporate from it? If yes, the larger container the quicker water will evaporate from it then if a container is smaller water will evaporate but at a slower rate. Experiment 1: Testable Observations Determine which of the following observations are testable. For those that are testable, answer the following: Determine if the observation is qualitative or quantitative. Write a hypothesis and null hypothesis. What would be your experimental approach? What are the dependent and independent variables? What are your controls - both positive and negative? Observations
