In-Class Experiment

Classroom Observation Conducting classroom observations are very important to the prospective teacher. Observing helps show how experienced teachers manage their classroom. For this observation it was important to notice how the classroom was arranged, how the teacher interacted with the students, the teacher’s management style, and interview the teacher.

PSYC 101 – Experiment Assignment (40 pts) Students will carefully observe acts of aggression and prosocial behavior on television, report their observations, and analyze their data to draw conclusions.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

Children in the experiment: A Class Divided Children in the experiment: A Class Divided In the video, “A Class Divided,” the video shows a teacher from Iowa named, Jane Elliot who wants to teach her students the importance of discrimination. During her experimentation, she starts off her lesson by asking questions such as, “What is brotherhood?” “What is discrimination?” and “How are we supposed to treat people who look different than us?” Elliot then proceeds to ask her class if they would like to know what it feels like to be discriminated. Her emphasis in this experiment is to show how it felt to be discriminated. Elliot was inspired to do this experiment when she was listening to the television the night after they assassinated Martin Luther king. She kept hearing the news reporter say things like: “who will look after your people?” and “How will your people manage?” After this she knew she had to explain to her class in a way they will understand. Elliot decided to divide the class into two categories: the brown eyed kids and the blue eyed kids. At first the blue eyed kids were the superior race while, the brown eyed kids were the lower race. Being the inferior race meant that they had to wear blue collars around their necks in order to differentiate their eye color. Of course, the brown eyed kids had restrictions. They could not play in the playground, they could not befriend nor socialize with the blue eyed kids, and etc. The kids had a chance to walk in

We can also take into account the factor of temperature difference between the mixture of borax and the crystallized borax which had settled on the bottom of the 100mL beaker. From what I have gathered during this experiment, crystallized borax was warmer than the solution above it. This is something that could greatly vary the results of an experiment as we could have pipetted 5mL of what we believed was 45*C solution but in actuality could have been much different due to incorrect temperature measurement.

Trial 2 I think this time blue on top will fail and seep into the red. So my guess was correct again. The blue water did slowly enter the red water.

Thesis The purpose of this experiment was to determine which temperature (hot, cold or room temperature) affects the growth of crystals the most.

Looking back at the first test trial of making the rock candy, there is plenty of room for improvement. To start off I would change the type of jar we are using into a taller, more slender one. This way we are able to see the crystals form better onto the wooden stick, as it was hard to see what was happening when we observed them. After reading the article about the crystals growing in the caves of Mexico, I believe that we can improve the experiment through the temperature. In the article it talks about how the crystals grew into giant sizes due to the temperature being very hot and consistent. So, if we were to put the crystal experiment into something else, it would be a container that will insulate the heat, like a thermos. The thermos

Method Participants The participants were 21 (19 female and two male) undergraduate students enrolled in a general psychology laboratory class at a small Midwestern university. The participants were selected by convenience sampling, and they received a grade for participating in and completing the experiment. Each participant completed the experiment, and the participants

This experiment has been split into several mini-experiments and procedures with the whole purpose serving to teach basic laboratory techniques. To begin, the first experiment requires the use of a meter stick or ruler which is then used to measure a lab notebook’s width and length in both inches and

For the Career Laboratory/Interactive Lab assignment, I selected tow Interactive Lab activities to critique. The two activities were the card sort and career matching game. I chose these two activities because I recently did an assignment on qualitative assessments and I was curious on how I would answer. I also

• The students in the fifth-grade classroom where I taught the two-day science lesson seemed to understand the objectives of the lesson fully. Throughout the lesson, I offered multiple opportunities for discussion and critical thinking from when the lesson first started, and until the lesson ended. During the first day of the lesson there was a section of it where the students had to debate or argue against one another if they thought they were incorrect with where they were placing their sort card. The student who wanted to debate against the placement had to present his or her own reasoning and evidence as to why the card should not have been placed there. I made sure to get every student involved with the card sort even if they did not debate against other students, he or she still had to present their own reasoning why they placed the card under the specific heading. All of the students during this time seemed to be highly engaged, and had no difficulty debating whether something was correct or incorrect. For the second day of the lesson when the students were asked to share their Venn diagrams most of them wanted to share what they had written or drawn on their diagram to the whole class. When we had our

The following lab report will determine if the mass of the unknown object be predicted based on the analysis of previous data. The purpose of this lab experiment is to find the mass of an unknown object. The way this experiment will be accomplished is through a use of the line regression method. This lab will begin with eight objects whose mass is known to see if there is a perfect fit relation between the mass of the objects to the period that is being tested. This lab consists of the use of five materials that included a standard masses, a stopwatch, tape, a C-clamp, and an internal balance. The procedure was simple, measure the time it took eight masses to get to ten periods cycles within the internal balance and record the results. One

Evaluation: There were couple of mistakes that occurred over the span of experiment. These mistakes could have irrelevantly influenced the outcomes obtained through the procedure. One common error that occurred was an extremely basic blunder within the lab and that was over-titration, which regularly happens. This is the point in which an excess of titrate is added to the analyte amid the trial. Therefore, the reaction passed the endpoint as too much of the essential sodium hydroxide was added to the Hydroxide arrangement. Fortunately, this occurred only in one trial. Case in point, phenolphthalein reaches its endpoint when it changes from being clear and straightforward to turning into a light shade of pink. In spite of the fact that this might be, for one of our trials when using this indicator the shading turned into a hot pink shade demonstrating that over-titration had occurred. An improvement for this component of the lab is simple. An improvement to control this error would be to use a burette with a smaller opening. This is because the endpoint can be overshot quite easily and this would ensure the error would not take place. It would have been best to manage the amount of base entering the beaker as much as possible with greater accuracy.

Classroom observation is a main approach of teaching research. Scholars or researchers use video to record the real whole class and observe the teachers and students’ actions, words and the efficiency in the class. Though the observation, they analyze what approach is more suitable. This paper will select video 5 and video 3 as the material to do the classroom observation. Different aspects such as teachers’ responds, questions, instructions notes and students’ behavior will be addressed to analyze the efficacy of this class.
