What are the 5 components of a proper graph?
the Cartesian plane for space, the x and y-axes, the points and lines, and the labels of the axes
List in order the steps of the scientific method.
observations, forming a question, research, hypothesis, experiment, analyze results, and conclusion.
Johnny was testing the affect of a certain chemical thought to cause cancer on different kinds of cells. He forgot to look at his microplate while loading the cells and realized that he had loaded the wrong kinds of cells into the wells. Johnny decided that he needed to move the cells and put them all where they were supposed to be before his research professor saw his mistake. When the results came back the numbers didn’t look anything like what they had gotten on the first few trials of the experiment.
What did Johnny do wrong? How can he improve his experiment?
by doing it right and making sure he has all his equipment in check
How could he have fixed his mistake without compromising the whole experiment?
putting the glass over the cells
