A team of scientists working at a particle collider perform the following experiment: Accelerate gold nuclei to incredibly high speeds and let them collide in order to produce and magnetically contain a small amount of the anti-matter which is known to be produced in these collisions. This experiment would best be called an observational experiment a testing experiment an application experiment You visit your friend and find her in her kitchen with a rubber ball and a bucket of ice water conducting an experiment. When you ask her what she is doing this is what she says: "I wanted to know if how high a rubber ball bounces is affected by its temperature so I'm dropping the ball a few times, then cooling it down with the ice water and dropping it again." Which of the following best describes the kind of experiment your friend is conducting and why? It is an observational experiment because it is entirely qualitative (no measurements are being taken). It is an observational experiment because your friend is trying to learn more about a phenomenon. It is a testing experiment because your friend is actively participating in the experiment. It is a testing experiment because your friend is testing the relationship between between temperature and bounce height. A team of scientists working at a particle collider perform the following experiment: They accelerate two protons to incredibly high speeds and let them collide in order to see what particles they can detect in the residue. This experiment would best be called an observational experiment a testing experiment an application experiment You are given the setup below where three metal disks are suspended by strings hanging from a rod. You are asked to conduct an experiment to determine if the length of a string has an effect on the time it takes for the metal disk to swing back and forth. Which strings would you use to conduct this experiment? Only one of the strings, it doesn't matter which All three of the strings Strings 2 and 3 Strings 1 and 2 Strings 1 and 3 While studying the salivation response in dogs, Russian physiologist Ivan Pavlov observed that dogs would not only salivate when they were fed but would actually start to salivate when they heard the footsteps of his lab assistant. Which of the following best describes this situation. This was a testing experiment because Pavlov's assistants were interacting with the dogs rather than passively observing them. This was an observational experiment because Pavlov did not take any measurements. This was a testing experiment because it happened in Pavlov's lab. This was not an experiment because Pavlov did not intend to make this observation. This was an observational experiment because Pavlov was not testing a hypothesis when he observed this.
