Can We Manipulate The Materials In Milk To Make The Stickiest Glue?

439 Words2 Pages
The leading question in the experiment was how can we manipulate the materials in milk to make the stickiest glue? By altering some of the ingredients and adding others, glue can be made. Depending on what ingredients and the amount being added, the more sticky or less sticky it will be. Based on our background information including all the Ingredients and what they do and how they affect the milk, the hypothesis that made the most sense in this experiment was, if we add more baking soda to the curdled milk, the glue will be stronger. The measurements recorded were set back from a complication. The glue popsicle stick had fallen apart without any force. Having to work with what happened, another group with the same independent variable was

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.

Our hypothesis was partially correct, the property changing substances did have the weakest coherency with the lowest drop counts of 23(carbonated), and 14(soap), and pure water did have the strongest bond. What we also found was the the salt also dampened the liquid’s ability to hold onto a penny in large volumes, as all the different salts had a drop average of 24(28x2 & 16), five less than Tap water’s drop count (30). This led us to conclude that pure water has the strongest bond and that all foreign materials weaken the coherency of water. This evidence has led me to believe that similar substances are attracted and are more coherent towards themselves, in this case the water pieces get separated and generally less connected on a really small level due to the obstruction of foreign objects, this is why the different salts perform better than the huge air bubbles or the slippery properties of soap since the latter is more obstructive and the former dissolves with the water and blocks less. When studying a few other groups’ conclusions and data we did indeed find differences: some groups had differing data where a solution had better coherence than water itself which led to differing conclusions.

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 .

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 some of the competitions that were performed there were prizes such as medals and trophies for the winning team, both teams had one goal and that was to win. The way they responded to these situations was the independent variable. The purpose of this experiment was to observe the effects of resources have on intergroup conflicts. In relation to the real world this is supposed to be a representation of how people compete for necessary things such as jobs. Although this is not the exact situation as it would happen in the real world it is an example of sampling.

The independent variable tested in the lab was the type of Oreo cookie. The dependent variable in the lab was the mass of the stuffing in grams. Two control variables are the scale we used and the same brand of cookies. My hypothesis was if I measured the mass of the filling in the Double-Stuff and regular Oreos, then it would show that Double-Stuff Oreos do not have “double the stuff” because the mass of the Double-Stuff Oreo’s filling would be less than double the mass of a regular Oreo ’s filling.

All three of these participants became frustrated when they were unable to communicate their wants and needs. In the experiment they used trials of who, and where. They would have them play with something like marbles then take them away and hide them. Then the participants would have to say, “where marbles”. If they communicated

Step two: Students placed their samples from the lake into four separate pans, which would later be carried to the lab to be analyzed. Step three: Before leaving the field there was about 16 round finfish that was captured and released back into the lake. Step four: In the lab, each student was placed in four different subgroups and given a pan full of samples from the lake. In each subgroup, students

They were 13 to 14 years old in the second grade of guidance school. Due to small sample size in classes the researcher had to select the participants from two classes to conduct the study. Both divisions were in the same situations and the same English teacher instructed them. Notice that in this research the teacher is the researcher too. Class A (N=16) assigned as the control group, and class B (N=16) as the experimental group.
