We reviewed some of the vocab Nicole missed on her quiz last class, and watched another video on the placebo effect. We discussed why a placebo is not necessary for all experiments with a control group. We then went over goals on level 1 and 2 on the learning goal scale, which included reviewing observation vs inference, qualitative and quantitative observations, scientific models, identifying variables, the scientific method, and replication vs repetition. We then headed outside to time how long it takes different sized vehicles to travel the 83 meters we measured out yesterday. Because of the parameters of the experiment, it takes patience to wait for the right vehicle to do the right thing, so we only got one piece of data today, but Nicole was able to use it to calculate the average speed of the vehicle. We will collect more data tomorrow. On our way out to the street and back, we stopped and examined several flowers and identified them as male/female. Nicole did a great job identifying potential vehicle "test subjects" and in timing the vehicles.
