The name of the lab is “Drops on a Penny.” I was expected to find the independant variable, dependant variable, write a hypothesis, and test the experiment. After testing the experiment multiple times, I needed to find the average amount of drops for each trial, graph them, and tell what kind of relationship it is. The last thing I needed to do was rewrite the details of the project and write a conclusion. The point of the experiment was to have the students get used to the idea of a lab, and get familiar with independent and dependent variables.
Our dependant variable in this experiment was the dissolved oxygen parts per million in each sample. We recorded this data on the white board back in our classroom, writing down the specific parts per million that we found in the water. The variables that were the same for all
Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
What were the variables? The independent variables are the male and female gender. The dependent variable are the dosage of bolus given. 1.
We were asked to correctly communicate these findings as we tested each of the substances she had encountered with both water and hexane. In experiment number three, The Relationship Between the Volume of a Gas and the Temperature, we where given a list of materials and asked to come up with our own procedure, which we did using zip lock bags filled with air, and submerged fully in a measured amount of water in order to find the volume, and then the change in volume when the temperature of the water was increased. In the fourth experiment we were asked to find the temperature of heated water, based on the cold and warm water. The experiment also required that each section be preformed several times in order to ensure accuracy, and also asked that the experimental responsibilities be split up between lab partners, each doing a section of the testing. This gave us an opportunity to work together with our fellow lab partners, with no one person doing the bulk of the work.
The independent variables that were used include: beans, temperature, light, darkness, reproduction, emerging adult bean beetles. The dependent variable used will solely be the oviposition chosen by the bean
In almost every experiment, there’s an independent and dependent variable, a constant, and a control group. The independent variable in this lab was the coins. The dependent variable was the density. The constant was the amount of water. In this lab, there was no control group .
Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .
a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?
The variable for each experiment will be the brand of toilet paper otherwise, for each experiment everything else will be
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.
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 independent variable in the experiment was the different types of locations used. In the experiment only two different types of locations were used, the park and the desert. In order to test the biodiversity and have accurate results it was needed to have multiple sites to test the effect of human interference. The differences in the two locations were that the desert had little to no human interference allowing time and room for the plants to grow, creating more biodiversity, versus the park which had many people who go through there causing damage to the area. The independent variable could be manipulated easily by choosing different sites to go to.
In this experiment, the independent variable is turning the stairs into a piano, or making the stairs “fun” to passerby’s since it is being changed in the experiment. On the other hand, the dependent
The Stanford Prison Experiment was an interesting movie. The way the experiment turned out versus the expectations was different and changed completely. The independent variable was the roles that the participants were assigned, which was determined by a coin flip. The dependent variable was the participants’ behaviors throughout the experiment. Some of the guards’ behaviors were cruel and immoral.
