What are the independent variables?
The independent variable for The Enriched Environment Study experiment is the type of environment, either an enriched or unstimulating environment, the rats are exposed to.
What are the dependent variables?
The dependent variables for The Enriched Environment Study experiment are the morphological and chemical effects of rat brains in an enriched or an unstimulating environment.
What controls did the experimenters include in the design of the study?
The Enriched Environment Study experiment included many controls such as having male rats who are twins, twelve rats that are randomly

The pipette was used to put the water into the behavior tray to create the wet environment in the second part of the lab. The water was used to create the wet environment. The procedure for the control part of the experiment starts by taking the Animal Behavior Tray and placing the filter paper in both sides of it. Next take the five Pill Bugs and place them into the behavior tray. Start the timer on the watch and observe the amount of Pill Bugs on each side of the behavior tray and how they are acting.

In this experiment, Pill bugs were exposed to different environments within a closed space and observed to determine which environment they preferred. The four different environments tested consisted of flowers, dirt, grass, and an empty space. Ten pill bugs were placed within the shoe box and observed for a total of 15 minutes to determine what environment the bugs preferred. The independent variables were the different conditions in each section of the shoe box, while the dependent variable was the behavior the pill bugs displayed. Throughout the experiment, the control variable was the empty section of the shoe box.

The experimental process could be improved by having more than two replications of each treatments. We could have 3 or even four treatments for each variable to increase the confidence in our results. If we increase the number of replications, any obscure data will be reduced with the average. This may allow us to see our data more

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

In 1938 Nicholas Winton grew concerned over the growing violence of Jews in a Czechoslovakian refugee camp. Since Winton knew that Britain had been already attempting to save Jewish children in an operation called Kindertransport from Austria and Germany, he needed to come up with a way to save the children in Czechoslovakia. Winton couldn't have worked alone. “As word of his efforts spread, thousands of parents lined up to implore Winton to save their children,” (“Saving the Children” 1).Winton got permits to transport the children into foster homes where they would travel on ships across the North Sea and trains from Prague to the Netherlands which would eventually let the kids be taken in by parents. Winton made sure that each children

The Constant Variable would be environment and temperature. The Materials needed for the experiment are pencil, paper bag, and stopwatch. There are two components of the procedures section, as there was a pre-lab activity, and the actual experiment. For the pre-lab activity, there was one group member who would breathe into the bag for three minutes, while another group member times thirty-second intervals. The other two group members would observe the

But, after retesting the experiment they realized that was not the case. Only the presence of the mouse seem to stop the elephant in their tracks. The independent variables in this experiment were the methods (such as the elephant dung, the string, the mouse) used as well as the breed of the elephant and mouse. The dependent

VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.

After comparing shared and non-shared environment, it was also seen in both studies that a non-shared environment has higher variance compared to a shared environment variance. In addition to having a similar conclusion, there was a trend within the numbers caused by the mean age of the samples. Samples from the Bergeman et al. study had an average age of 59 years while the samples from the Jang et al. study had an average of 31 years. This concludes that age can also be a factor that would influence the environment and the genetic influence (Table 3)
