Tools & Instruments 400pts.During the summer a student noticed the color of the clothes she wore affected how hot she felt. The student designed an experiment to test this. The student obtained four identical samples of sand. Each sample was covered with a different color of cotton fabric. Each sample was then placed directly under a 110-watt light bulb. The student recorded the initial temperatures of the sand, then turned on the lamps. At one-minute intervals, for six minutes total, the student measured the temperature of each sample. The data are shown in the figure below.Which of the following instruments would be necessary to collect the data in this experiment?

Many human features, such as height, hair color, and bone structure, are determined by genes and the influence of the environment on the action of genes. The effects of different genes and their interaction with the environment produces variation (measurable differences in features among individuals). As part of an exercise on variation, an Ohio class measured the heights of both female and male students. The distribution of heights is shown in the figure below.

In order to collect the data, the students would have needed to use which of the following pieces of equipment?

The custodian in Brandon’s school used a cleaning solution mixed in water. Brandon wanted to see what effect it had on students in his classroom, so he set up a model. He placed 5 fruit flies in mesh containers arranged in the same pattern as the desks. He then added undiluted cleaning solution and covered the entire container so outside air would not contaminate the model. When the fruit flies died, Brandon concluded the solution was harmful. The custodian said his cleaning solution had been approved as safe, and that it was the model that had some problems. How could Brandon strengthen his model?
