Superworm Lab

The Dependent variable for this study is the amount of water absorbed by the paper towels. This will be measured in milliliters. The independent variable for this study is different brands of paper towels. The controlled variables will be the amount of water the paper towels are given to absorb, the size of the paper towels at the beginning of the experiment, and using the same measuring instruments in each trial. I will reduce the threat to internal validity by conducting the experiments in the

There are several parts to the experiment such as both the independent and dependent variables. The independent variable is controlled or changed during the experiment to test the effects on the dependent variable. The dependent variable is tested and measured during the test .A controlled variable is an example for an independent variable would be variable that is held constant throughout the experiment. An example is a theory that could extend a person’s life expectancy. The independent variable is the amount of vitamin given to the subject within the experiment. The dependent variable is the life span

One sowbug was then placed in the 3cm gap of the container and 30 seconds was started on the stopwatch. When time was completed we observed which side, grass or sand, the sowbug had preferred. Then, the sowbug was removed and a new one was placed in the container. The same steps were taken for each of the 20 bugs.

In our Penny Lab, we wanted to extend what we were told to do with experimental design. We’re doing this because we wanted to prove what he thought our hypothesis had been, and a hypothesis can not be true unless it can be tested. We investigated what variables made the Penny Lab easier, or harder. As a class we decided to investigate variables like, dropping the penny from the same height, and applying the same pressure to the penny for each drop. But first we had to know what variables were, and which variables we needed to use in the experiment. The variables were, the independent variable, dependent variable, the experimental group, and the control group. We investigated this to show how much water a penny could hold, but we introduced

Keeping the experiment isolated on the focus of body size is as simple as not changing any other variables concerning the experiment. Therefore, predator number, predator size, habitat type, and any other possible variable in the experiment that is not body size will be kept as consistent and identical throughout the groups and replicable tests as

The purpose of this lab was to save a little gummy worm named Sam from drowning. In addition, one of the labs key terms was a hypothesis which is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Furthermore, we also learned that an independent variable is a factor that is changed during the experiment. On the other hand, the dependent variable is the factor that is observed or measured during the experiment. To begin with, the experiment the hypothesis formulated was if we reshape the paperclips into hooks and pick up sam, and the lifesaver (without touching them), then the lifesaver would be stretched enough for Sam to go through it.

The main reason of choosing the stimulus for the lab group was to conduct an experiment to see in which colored light that pill bugs prefer more out of red and blue. If pill bugs went to red more than blue lights, in which means they like bright light more. The pill bug move slowing in red side of the chamber then moves to blues side of chamber, where it return back to red side of the chamber where it stay immobile .The pill bug adapted to red and blue light which show more significant their locomotive movement.

Question: What will happen to a gummy bear if it is left in water for 24 hours?

In this gummy bear lab, the goal was to see the movement of water in cells depending on the concentration of solutes in the environment. The control group was the type of water used. The research question for this experiment was, how does concentration of solute in the environment affect water movement in cells? The hypothesis thought of for this question was that the salt water would enlarge the gummy bear the most. The distilled water would not enlarge the gummy bear as much as the salt water.

The pill bugs lab was done to solve the problem of which type of food the pill bugs preferred, cucumber of pepperoni. My hypothesis was that the pill bugs will favor cucumber over pepperoni. In order to carry out this experiment, we used the chamber method to determine which food was favored by the pill bugs. Pieces of cucumber and pepperoni were placed on each end. Then five pill bugs were placed in each chamber, and their movement was observed and recorded. Because the results were so close to each other, we concluded that their reaction to the stimulus was a kinesis reaction, and it is only random. My hypothesis was not true because the standard error from the number of pill bugs in cucumber chamber and pepperoni chamber overlapped. This means that there is no scientific reason for why the pill bugs chose cucumber over pepperoni. I learned many new things in this experiment, such as, how to use a choice chamber, and how to calculate the standard deviation and error of the data. Also, I learned how pill bugs react to an outside threat.

The independent variable of my experience meant is what I’m going to be changing which is the substance, coffee. The dependent variable of my experiment is the Daphnia’s heartbeat per minute, which will also increase immensely. The units I will be using to collect the data is one minute per trial.

We started out with three populations; B, D, and G. In order for us to properly create controlled genetic crosses, we had to ensure that all the female flies were “virgins”.

Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with a hard shell, the New Guinea Flatworm latches itself onto the shell’s opening and then spits out its own stomach through the opening in its belly. This allows an acidic goo to dissolve the snail’s flesh and the worm can continue on with its meal by swallowing both its stomach and the snail.

I love gummy worms I been in a gummy worm factory I fell in love with it just the flavors and sweet texture just grab my attention not in that way. I use to buy gummy bears a lot everyday I had a little bit of a sweet tooth my mom just always buy me some gummies at dollar the store. It's kinda funny how i just always on my birthday my mom would ask me what i want for my birthday I would just say money and gummy worms. My mom would just be cool with it she really didn't even care she wasn't buying expensive things that's why.

* In every experiment there are variables that affect the way an experiment will go. The three types of variables that are measured are Independent, Dependent, and Controllable variables. In my experiment the Independent variable is the three different models of paper airplanes that I have chosen to make and experiment with. The Dependent variable includes the distance the paper airplane goes. The Controlled variable is me making sure that I throw the paper airplanes from the same starting point a well as the same weather conditions. The controlled variable is the one that cannot be changed because it would affect the other two variables. In this case I threw them in my house since I have a very long hallway that leads into the front family room and there is no furniture that would interfere with the results.
