Lesson Planning

Until this course, I did not realize the true extent of creating lesson plans, let alone unit plans. A lot of time and patience goes into creating a great lesson plan. Looking back at our direct lesson, we should have made that part of the lesson a little shorter and more concise. I wish that we had known all that I know now about creating successful lessons. For our inquiry lesson, we should not have been as ambitious as we were. In reality, having four labs going on at one time, was a bit much. We should have had one lab experiment (like the other teacher candidates ended up doing) so that we could have spent more time working on that lab and gathering the data. We were so focused on completing each lab in time, that not all of the students were able complete their investigation sheet. When I was completing the EdTPA, I wish that I had more student examples and completed work. As the first group that went, we did not know we had to keep the student work and those samples we ended up saving came from the garbage! As the saying goes, you live and you learn or hindsight is 20 20!
                                                  
If I were to do this again, I would take a completely different approach to the fieldwork lesson. I would make sure that my direct instruction was short and to the point. I would also incorporate more technology learning activities, like smart board games or even having the students come up to write on the board. I would also only have one experiment, so that we could focus on completing that and sharing our results and findings. We unfortunately did not get much time to go over our results and findings. It is very important that scientists share their findings, so that they can compare and contrast with others. The Scientific Method will also be incorporated into future lessons, as this process is very important to students to know.
                                                     

Research article review


I chose the article, “Breaking Science Stereotypes” by Alec Bodzin and Mike Gehringer. This article appealed to me because it made me think back to our first class and how we had to draw a scientist and almost all of us drew a male scientist (even with the majority of the class being females)! The authors of this article wanted to see if a scientist’s visit to the classroom would change students perceptions of scientists.
This article also had the students they were working with draw a scientist  and write about the scientists they drew. These drawings were scored using the “Draw-a-Scientist Test-Checklist,” which has common stereotypes of scientists that other students have had in the past. 
The first scientist that these students met was a female chemical engineer. “As the scientist spoke, she described that there were few females in her profession and encouraged girls in the class to enjoy science and mathematics in school and consider careers in science” (Bodzin & Gehringer, 2011, p. 37). I thought that it was great that this female scientist was the first scientist to visit the classroom, because I am sure that is not what the class was expecting. It is important for young females to have role models to look up too and aspire to be like one day. I feel like most young girls don’t see or think of many females in the science or math field. The scientist also wore a blue lab coat, instead of the stereotypical white lab coat that many people think a scientists wears. The lab activity she chose for the class to complete was great, as it was hands on and allowed the students to complete an experiment very similar to what this scientist does for her job.
The other class had a male physicist come to their class and he wore a shirt and tie, instead of a lab coat. He gave the students rubber gloves and goggles to wear while he conducted a number of demonstrations. By allowing these students to observe these chemical reactions in person, it not only taught students about changes in matter but also made them interested in some of the things that a physicist does.
After the scientists visited the classes, the students were asked to draw a scientist again and the researchers compared both drawings.
“In both drawings, students drew scientists with several types of stereotypic features, including laboratory coats, eyeglass, and symbols of research such as laboratory tables, flasks, test tubes, and so on. In most of the drawings scientists were depicted as white males working indoors in a laboratory setting” (Bodzin & Gehringer, 2011, p. 39). It is interesting that both these students and our class had many of these stereotypical drawings and features in our pictures. “After the visit, the students’ drawings depicted fewer scientists wearing lab coats (60.9 percent down from 85.5 percent) and eyeglasses (46.4 percent down from 53.6 percent). Also, more female images were drawn during the posttest” (Bodzin & Gehringer, 2011, p. 40). Overall, all of the common stereotypes that were found in the drawings before the scientist visit were found less after in the drawings after the scientist visited.
“It appears the that interaction between the scientists and the students during the classroom visit influenced the students’ perception regarding scientists. The scientists’ visits provided students with the opportunity to see scientists as ordinary people” (Bodzin & Gehringer, 2011, p. 40). I think that this last sentence is so important. Many students have only read about or watched scientists in movies before meeting one in person. The scientists they read about or watch in movies are given these stereotypes, thus, why these students have a certain image of what a scientist looks like. It is great that these researchers wanted to break that stereotype and broaden the image of who a scientist is. “Furthermore, we believe that exposing young girls to female scientists in an elementary school classroom may have a positive influence on their perception of careers for women in the science and engineering fields” (Bodzin & Gehringer, 2011, p. 40). Young girls often hold the misconception that their future career may be in teaching or nursing rather than science and research. Although, the science field is male dominated, there are still women who work in these fields. It is important for you girls to realize that they really can be anything that they want to be and that the world is their oyster. The incorporating of STEM classes into elementary classrooms is a great way to get students involved in the math and science fields, especially girls. I wish that my elementary class had more of a STEM program when I was there.  
It is important that this stereotypical image of a scientist as a white male is broken at a young age. Had we had this experience in our elementary classes, we probably would have all drew different images of scientists. Hopefully, as the time goes on, there will be more and more female scientists and that they will be depicted in textbooks and movies. Right now, it seems like only males are represented in these medias. Although breaking the stereotype of the image of a scientist may take a while, it is our job as future educators to make sure that we help teach our students who a scientist is and what they do. I hope to incorporate having scientists come into my future science class to do an activity similar to these researchers.

Science Fair Project...Middle School Style

What does it take to complete a Science Fair Project? This assignment gave us the opportunity to create and carry out a Science Fair Project, just like the students of Bishop Dunn were.

The idea behind completing this project was so that we would know what our students would be going through if they were assigned a Science Fair Project. It is important for students to work with the Scientific Method and use all of the steps to complete an experiment from start to finish. 
This process allowed me to become aware of all of the expectations and work that is required to create a successful and meaningful project. There is time and work required to create a Science Fair project. It is not a one day project, instead, it is one that takes days, even weeks to complete properly.  
Now that I have completed the project, I am aware of the work and steps it takes to create a science fair project. It all starts with the brainstorming phase, then the developing stage and creating stage. I know that students will have the most trouble coming up with an idea and I want to make sure that I help each of these students to the best of my ability. It is important that they have a project that they are interested in. If they are interested in the project and outcome of the experiment, they will put their best effort into the project. 
For this project, I chose to ask the following question: "How can we prevent an apple from browning once it is cut?" I then went on to investigate if an acid solution or a base solution would be the best option to prevent the browning of an apple. I thought this would be a good science fair project as I have an interest in seeing which solution will keep my apples from browning and prolonging their edible life. I knew that this project would lend itself to a number of results, which I would be able to use to prove or disprove my hypothesis which was: "Acidity of a solution or liquid does effect the rate of of the enzymatic browning of cut apple slices."
Here is a close up picture of my apples at the beginning of the experiment:
This is a close up picture of the apples after they have been exposed to the acids and bases:
From my experiment, I found that the apple slices in the water and lemon juice browned the least of all of the samples used. 

Here is my finished projects poster board: 

Book talk and creating a book talk trailer!


We had to create a book talk for a Science Trade Book that could be used inside the classroom. I think that trade books are a great tool for teachers to use, instead of always referring to Textbooks, as those can get old after a while!

I chose a book called Egg: Nature's Perfect Package because we just recently had chicks hatch from eggs that we had in incubators at the school I work. I saw first hand, how this activity really got students excited. This book has great illustrations and facts about animals who lay eggs, what the eggs look like, etc. You can find my book talk here.  The book talk is a great activity, as it highlights the important aspects of the book and how teachers can apply its use in the classroom.

Dr. Smirnova also challenged us to create a "Book Talk Trailer" to add the digital teaching aspect to the assignment. I was a bit apprehensive about this part, as I had never used any of these recommended websites! I chose to go with GoAnimate and created my trailer with that website. It was actually so much easier to make that I thought it would be. I chose to use two animals talking about the book, since the book is about animals! I think that my trailer came out really well and it leaves the viewer wanting to go get the book.

After I created and saved the trailer I found out that I was not allowed to share the video because I was not a subscriber to the website, which was a bummer. So I had to get creative! I recorded my GoAnimate video with my phone and uploaded it to YouTube, another first for me! I was able to upload my video from my phone right to my YouTube app, I could not believe how easy and quick that process was! You can check out my trailer here. I hope you enjoy it as much I enjoyed making it!



This class has continued to broaden my horizons with my "tech savvy" abilities!

Astronomy in the News

                                             

The comic above gave me a good laugh! :)

For a few weeks of Science Methods, we spent some time working on Space concepts. One of our first activities to get us into the topic was to find a number of news articles about Astronomy. 
                                              

I was surprised to find so many articles that were released so recently. Apparently, news about Space is almost as frequent as the interesting quotes the Presidential Candidates are making! 

The first article I found was, "Black holes mysteriously align." This article talked about supermassive black holes in the distant universe are all spinning out radio jets in the same direction. Scientists believe that this spin formation began when the galaxies first formed in the early universe.

The second article I found was, "SpaceX makes waves with landing at sea." This rocket was able to send supplies to the International Space Station and then land safely on a landing strip in the ocean. Other rockets have not had as successful time of a landing/recovery of the rocket in the past. 

The third article was, "An artificial comet holds secrets to Earths life." Researchers have created an artificial comet that contains ribose. Ribose is one of the building blocks of genetic material, which may have actually formed in cometary ices. 

The fourth article, "Supernova showered earth with radioactive debris" discusses a series of supernova explosions near our solar system, which happened millions of years ago. According to Scientists, this explosion contained radioactive debris. 

The fifth article, "Early Mars bombardment likely enhanced life-supporting habitat," was about Mars having a certain atmospheric pressure that would have supported a water cycle. 

The sixth article I found was, "Saturn spacecraft not affected by hypothetical Planet 9." Scientists are saying that NASA's Cassini spacecraft is not having any changes in its orbit around Saturn. Some thought it may have issues, due to the proximity of Planet 9. 

The seventh article I found was, "New gravity map gives best yet view inside Mars." This article discusses the technology that is used to see inside planets, much like x-rays used to see inside Humans. This will be helpful for scientists to learn more information about Mars. 

All of these articles, provided me with informative and current information about Astronomy. I hope to incorporate a "Science- Current Events" into my future classroom! 

You can access my news articles from the Glogster I created for this project.

What's going on with the Earth's poles?

I'm sure you are wondering what I mean when I say poles... I mean the North and South Poles!        

                                                     

A few weeks ago, I came across an article that caught my eye. The article, "Climate Change May Be Causing Earth's Poles To Shift" by Jacqueline Howard and Chris D'Angelo. According to the authors, the Earth's axis position has shifted its location. A new study in the journal called Science Advances claims that this shift is due to melting ice sheets and changes in water storage. To me, this is very concerning! There are so many he said, she said controversies surrounding climate change, yet here is even more proof that climate change is REALLY happening!

According to Erik Ivins, who is a scientist at NASA: "... the movement of water on Earth's surface affects the planet's distribution of mass- and its axis- much like adding weight to a spinning top" (2016). He goes on to state: "The researchers wrote in their study that the Earth's spin axis has been shifting 75-degrees eastward from its normal long-term drift since the early 2000s" (2016).

This kind of shift seems like a big deal, but the scientists say it is not something to be alarmed about now. Apparently, this will not really effect us. I think that this article is just another example of how Global Warming is negatively effecting our Planet. Even though scientists don't believe this to be harmful, it is still a change! I can't imagine it providing any positive changes for us!

It's been a while....

Woah, where has the time gone?! Between snow days, class, assignments and work- I have fallen behind in my blog posts! Hmm, what has been going on since last time?

All of my classmates and I have completed our Science lesson plans. It was really interesting to see how different each of our lessons actually were. There was a lesson on Life Science, Earth Science and the Scientific Method.

The second group (after our lesson- which seems like so long ago- especially with all of the snow days in between!) had the topic of life science. I was curious to see what topic they would teach in this broad subject. Actually, all of our subjects were very broad and I know that it is quite difficult to narrow down the subject to one topic. My group went through a few ideas before we finally decided on our topic- so many choices- so little time. And most importantly, what will the students enjoy the most?

The teacher candidates did a lesson on the Dichotomous Key, something I remember doing back in Middle School! The direct instruction lesson was done really well. I liked how they used the SmartTools for their presentation/lesson and all of the tricks they were able to do with this program. It was very interactive and really kept the students engaged. The lesson had great flow and the two teachers were well prepared and worked really well together .

During the inquiry lesson, the teachers conducted a lab with the students, which the students absolutely loved. They had to use a Dichotomous Key to figure out the flavor of the Harry Potter Jelly Beans. I thought this was a great idea for a lab and really allowed the students to use their new knowledge about a Dichotomous Key. Some jelly beans looked really similar and if the students weren't careful- could end up identifying a peach flavor one as vomit! Could you imagine?! I was not brave enough to try the gross flavors, but I heard that they really are true to the taste! Once the students were done identifying the different jelly beans, they were able to try them out. The students really enjoyed the lesson and the teachers did a great job!
