What were the learning outcomes for the lesson? How did the learning outcomes meet the needs of individual students?
The learning targets were met; therefore the following was the outcome:
The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.
The 3D models created a bridge from the abstract to the concrete. Ionization energy is difficult topic to for students to analyze and to “visualize.” The 3D model for ionization energy enabled the student to use visuals to identify which elements in the periodic table require the largest amount of energy to remove valence electrons. The 3D visual enabled them to notice the general periodic trends about each of the characteristics. In addition, students with limited language proficiency were able to relate the size of straws to the properties under investigation—these students determined that larger straws indicate larger ionization energy relative to other straws that represented different element ionization energies.
How successful was the lesson? Did the students learn what you intended for them to learn? How do you know?

The first one was “Informational Texts” by Nicole Gavin. In this video I saw a second grade classroom with English learners. In the lesson the students where reading about information about certain animals. They were thinking about questions. I personally, liked how they touched their heads when doing this thinking process. In addition, while they were reading, they were writing questions on a post-it note and sticking it on the book, which prevented fake reading. Moreover, they were working in groups of 2 and one member said the question that his partner had, which builds listening skills. With this lesson idea I learned so much. I learned how to make group learning interesting and how to have the students get a better understanding of what they are reading. Also, to have the students ask questions while reading as opposed to after when most likely they have forgotten half of them. Finally, I learned how the teacher use informational text with the students that creates questions, which lead to facts. These facts, become learned material due to the great amount of thought that went though. This again, will build in other subjects that the student will need for later in his or hers education. The second lesson was the “Formative Assessment: Collaborative Discussion” by Kelly Bouchard. In this video it was about fourth graders who were English learners. This lesson has four parts that the students need to do to be able to have a successful criteria. First, is define, which isn’t really part of the four parts. It’s where the teacher gives the question to discuss. As a result, a student collaborates on their own idea. Once that is set the first step is to clarify, which clarifies intended learning. Second, is elicit, which is elicit evidence of learning. Then, is to interpret, mining, to interpret the evidence by asking questions and by linking your ideas to others. Finally, is action, which
Dimitri Mendeleev was considered the first chemist to discover that patterns would become apparent when elements were classified to their properties. Mendeleev’s adjustment of elements was the one and only due to his idea of leaving blank spaces for elements he believed were undiscovered in 1869. The purpose of the Mendeleev Lab of 1869 is to use knowledge of the periodic table in order to identify the undiscovered elements. Ultimately the whole idea is to observe, and draw conclusions to identify the elements. For instance, observing properties, samples, and trends will help us learn more about the periodic table also, learn more about the hidden elements of Mendeleev’s Lab.
She is not only interested in learning new topics, but also grasps the concepts quickly. Since summer, she was looking forward to learning about the periodic table. She questioned about how atoms join to make a molecule and researched on the structures of Sodium Chloride and water molecule. Due to her interest to learn about various elements and questions about Carbon as an element, her elder sister introduced her to the concepts of organic and inorganic chemistry.
Over the past millennia, our understanding of the atom has evolved through eager hypothesizing, numerous trials and startling discoveries. From the first atomic theories of the Democritus in Ancient Greece to the gold foil experiment that allowed Ernest Rutherford to discover the atomic nucleus in 1909, humanity has come far on the path to crack the mysteries of the atomic structure and the hidden secrets that lie within. However, it was only in the 1930s that the full basic structure of the atom was finally completed with the discovery of the neutrally charged particle known as the neutron.
This chapter talks mainly about the importance of the periodic table and discusses some of the stories behind some unique and important elements, along with interesting scientific discoveries. Chapter 1 really intrigued me, and I wasn’t expecting that. Even after I read the back of the book summary, I still reluctantly started reading. However, I don’t regret it now because this book is pretty fascinating.
1.Obtain, evaluate, and communicate information about the use of the modern atomic theory and periodic law to explain the characteristics of atoms and elements.
Electronegativity and Ionization energy increase from bottom to top in a periodic table. P1.00 has the highest ionization energy (smallest atomic radius) as a result it has the largest band gap energy. The data shows as the size decreases (ionization energy increases) the band gap energy increases.
The periodic table was a display of all known elements ordered in increasing atomic number. The modern periodic table has groups, a column of elements, and periods, a row of elements. Elements within the same group have similar chemical properties because they all possess the same amount of electrons in the highest occupied energy level, also known as valence electrons. Due to the fact that chemical properties are determined by electron configuration, elements in the same group will react similarly. This was because elements in the same group want to lose or gain the same amount of electrons, in order for them to become stable ions. For metals, the elements lose electrons in order to become stable ions and nonmetals gain electrons to become stable ions. All the elements in a group will
The purpose of this lab was to determine the atomic structure of small molecules and ions which we did by drawing Lewis Dot Structures, drawing molecular geometries, and using the VSEPR model on a computer. The VSEPR Theory states that molecular geometries of molecules can be predicted through their number of electron pairs on the central atom because these electrons will repulse each other as much as they can while still being bound to the central atom. The Lewis Dot Structures and the molecular geometries that we were asked to draw were in order for us to have background knowledge of how each molecule was shaped before we had to make them on the computer.
One of the biggest weaknesses in executing the lesson, to include a self-assessment, was my lack of ability to learn names quickly, fully understanding the climate of the classes, and lack of experience with teaching the subjects. Many day to day adjustments had to be made in both subject areas. One in particular for the Geometry classroom was that the PowerPoint presentations had to be adjusted to further break down and reteach Algebra concepts, the lowers level learning objectives, prior knowledge that did not consistently transfer to this classroom. In addition, the anti-bullying assignment was changed from a group assignment, an anti-bullying campaign to an individual quick write essay where basically the whole class successfully shared
I am going to discuss the modern concept of the atom. I am going to give a brief history of the atomic model including Thomson's atom, Rutherford's atom, Bohr's atom, and Schrödinger's atom. I am going to include a diagram for each of these models.
