• Classroom Environment
I observed a second grade classroom on Wednesday November 18, 2015. During science block time, and the experiment I observed was chemical reactions. I arrived fifteen minutes before the science block time, because I wanted to observe the transition. The transitioning indeed was smooth, and the children shared their happiness about the science experiment. The class on this day had the 23 students and the teacher present. During my observation I was able to observe the classroom environment during the science experiment, teacher-student interactions, and science process skills. During my observation I was also able to learn a lot of strategies to teach science. For example, my host teacher asked a lot of questions, and even if the students answer the question correct the teacher kept asking more open-ended question. Also, I noticed the teacher used a lot of science vocabulary words such as, collecting data, observation, prediction,

The experiment process was for the students to inquire about the reaction of the chemicals when mixing them. The materials were, a jar, a spoon, baking soda, dish soap and vinegar. The teacher wanted to demonstrate the chemical change to the whole class. So the students observed the materials first, then the teacher assisted the students to combine the materials. While the chemicals were reacting, the teacher was asking open-ended questions. Also, the teacher ask the students to draw a picture of the reaction. The teacher then explained that the when the baking soda and the vinegar are combined is when the chemical change reaction happened, and the bubbles form because of the reaction. The teacher was very attentive to all the students’ questions, and I noticed that by labeling the materials and pointing at all the steps she was doing she was accommodating student
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.
For this lab the knowledge to tell the difference between a chemical and physical changes was needed. To tell this the knowledge of the five signs of a chemical change was needed. These five signs are color change, odor change, production of bubbles/gas, production of heat/light, and the production of precipitate. Also prior to the lab one question was provided that needed to be answered. This question was what chemical must be present for a color change.
The teacher starts with pictures related to pollution in the environment. T shows it on the PPT and students try to guess what it might be. (Appendix 1) The teacher elicits answers. The students are expected to say “pollution” and after they say this word, the teacher writes it on the board.
The Honors Earth Science classes went to the Susquehanna River to solve a problem. The problem was not knowing if the is healthy. The classes want to know if the river is healthy, because the students live near the river, and it affects the classes everyday lives. To answer the problem, the classes did a series of tests, and made physical observations at various islands in the river. The students used test kits and other tools to test pH, temperature, phosphate, nitrate, turbidity, and dissolved oxygen.
The fourth finding I found was that even though Pre-K environments have an emphasis on group activities there was often a designated area in the classroom where children could go and be alone and self-reflect. However, these spaces were used differently throughout the three programs. In one program children went to what they called the “cool down chair” when they misbehaved. In this particular program usually a talkative child who may have been disruptive would have to go to the chair and think about what he or she did wrong. The chair was located in a corner where there were crayons and other play items that the child was allowed to use, but mainly it was a sort of punishment.
1. Which actions by the teacher seemed to support student engagement and understanding? During the explain portion of the 5E lesson, Dr. Bradbury supported student engagement and understanding by asking higher level thinking questions; evidence for this can be seen in sections .35-1:15 min and 9:19-11:26 min of the video. The questions Dr. Bradbury asked provided an opportunity for rich in-depth conversations by student to discuss the idea of heat transfer.
The hypothesis that the scientist will be testing is that alka seltzer tablets with smaller particles will react faster than tablets with larger particles. This would happen because the water would not have to break down the tablets as much as it would with the tablets with larger particles. Without having to break down the tablet, the water could begin reacting immediately with the tablets having smaller particle size. The scientist will do this by placing tablets of alka seltzer, each with different particle sizes, into water, and measuring the
Do not believe in Cuttimungus; that is what my eighth grade science teacher taught me. Walking into my science class on the first day of eighth grade was very exciting prospect given that I had the same teacher I had in seventh grade; a year filled with exciting hands on experiments and projects. My love of science, having already been sparked the year before, had led me to enter the science classroom ready to learn as much as I could. What I didn't know at that time was that this class would have such a huge impact on how I looked at the world.
Unselds’ School Classroom Observation Report Background of the Unselds’ School The Unselds’ School is a private school, located in Baltimore, Maryland. The school teaches less than one hundred students from the ages of nine months to teenagers in the eighth grade with a faculty of fourteen. The goal of the school is to provide their students with the necessary skills needed to be accepted and potentially awarded scholarships to high schools that are beneficial in furthering the child’s education, as the public high school of the county has a graduation acceptance rate of forty-eight percent. The Unselds’ School has a thematic teaching approach, which means that the curriculum implemented is based around key subjects and concepts.
Case study The case study entitled, “The Classroom”, is about a teacher, Frank Oakley, and his struggle to find the proper way to teach his physical science class. Since teaching requires preparation, we look at several different topics. It is important to note what lesson Frank wants the students to learn, however, it is also important to know the time allotted, materials at hand, previous experiences, and an objective. While the lesson is all taught at once, the teacher will focus on these main parts.
The second question asked was, “Describe how the new mixture is different from the original substances?” The new mixture that was created is different from the original substances because when you would touch the mixture is was a chalky feeling liquid and when you wouldn’t touch it at all it was a solid. From the original substances to the new mixture the cornstarch was very soft and felt like powder sugar and the water was so clear that you could see through it. The third question that was asked was, “Was the new mixture made from a physical change or chemical change? How do you know?”
Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of
Then the balloon is lifted up so that the baking soda runs into bottle to react with the vinegar inside. Immediately the balloon is inflated by the carbon dioxide formed. The baking soda is kept constant when the experiment is repeated for another different amount of vinegar. Results/Findings When sodium bicarbonate and vinegar mix,
On Wednesday, September 30th I observed Mrs. Bangham’s three to six year old classroom. The observation was from 8:00 to 10:00, at Greensboro Montessori School. Since they combine different ages I focused more on the five and six year olds that would be in a normal Kindergarten class. I learned so much about Montessori schools and how they work in the two hours I observed.
The classroom that I will be observing is a Preschool classroom at KinderCare Learning Center in Bartlett, Illinois. The teacher I will be observing over the next period of time is Laura Sturgulewski. She has worked at KinderCare for 8 years, mostly in the 2 year-old room until fall of 2013, when she took the lead teaching position of the Preschool classroom. Her classroom mainly has 3 year-olds, but on occasion has a mix of 4 year-olds and transitioning 2 year-olds. The number of students in her class depends on the day, because they are a child care center some students have a part time schedule, unlike an elementary school where children attend every day.
