Student Exploration: Sight vs. Sound Reactions Vocabulary: histogram‚ mean‚ normal distribution‚ range‚ standard deviation‚ stimulus Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Most professional baseball pitchers can throw a fastball over 145 km/h (90 mph). This gives the batter less than half a second to read the pitch‚ decide whether to swing‚ and then try to hit the ball. No wonder hitting a baseball is considered one of the hardest things to do in sports! 1. What

or hourly wages would be equivalent to. 1. Suppose a winter jacket costs $80 in 2003 and inflation was measured at 27% over the period from 2003 to 2013. If all other variables were to remain constant‚ how much would that jacket cost in year-2013 dollars? Use the inflation formula below to complete this calculation:

calculate the fraction that will be used up after 6.0 minutes. 4. [15 points] The rate law for the decomposition of ozone to molecular oxygen 3 O3 (g) −→ 3 O2 (g) is rate = k [O3 ]2 . [O2 ] The mechanism for this process is k1 O3 O + O2 k−1 k 2 O + O3 −→ 2 O2 Derive a rate law from these elementary steps. Clearly state the assumptions you use in the derivation. Explain why the rate decreases with increasing O2 concentration. 5. [15 points] Consider the following

Bob Rosenthal’s famous rat study. In this study‚ participants are told that their rats are either “smart” or “dumb”. Then‚ after interacting with the rat‚ they have them run a maze. Interestingly‚ the rats that were labeled‚ and treated‚ as “smart” performed better. This effect has also been found in the classroom‚ where teacher’s expectations of students translates into IQ scores. Next‚ enters the Batman‚ otherwise known as Daniel Kish.

Transfer of Food Preference in Rats after Initial Taste Preference ---------- --------------- Abstract Rats are animals known to be neophobic‚ fearful of new experiences and tend to show behaviors of avoidance to eat novel foods. However‚ there are high chances that rats will eat novel foods if they have reasons to expect that the food is safe to consume and not harmful. The social transmission of food preference paradigm (STFP) was tested in 28 male rats that were about 5 months old

The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute.
