For the lesson observed the objectives was to explain the trends of the periodic table based on the elements’ valence electrons and atomic numbers. Additionally, students were responsible for applying their previous knowledge in calculating subatomic particles to review the Bohr Models and discus the relationship among families in the periodic table. Students will use the information from today’s lesson to make future judgments on reactivity and bonding created during chemical reactions in the next unit. Lastly, students were to connect the information on elemental properties to previous experiences with their health, commercial products, and everyday life.

Once questions are answered and all students feel comfortable moving forward then give introduction of the lesson activity.

Using elemental analysis to determine the percent mass composition of each element in a compound is the first step in creating an empirical formula. There are many different types of elemental analysis, but in this experiment gravitational analysis and Beer’s Law are used. Elemental analysis is first used to find the moles of each element, then converted to mass, and then the percent mass of the element in the product is found (2).

We can use the small numbers to give information about the particles in the nucleus.

Students will be asked to write down anything they don’t understand from the lesson on a piece of paper (? Cards-see appendix 2.2) and it will be collected by the teacher

Next, as a group, we decide how to present the information in front of the class. This assignment strengthens my research skills, communication, problem-solving decision-making and the ability to take criticism. My improvement in these area has allowed me to be effective in further my education, as a union delegate, as a client advocate and an effective leader in my

YOUR TASK 1: You will begin today in class before the last day. You will discuss about your WebQuest and review the task to understand what is required to complete each task.

To maximize the students’ knowledge, this mandatory meeting should be held at the beginning of the school year during the fall term.

Answer- As the objective states, student’s behavior will be measured as they are expected to complete five addition problems with like denominators and three word problems. Students will also partake in coming up to the whiteboard and explaining to their classmates why they got the answer they did for either a word problem or an addition problem, followed by, a student slowly reading each part of the problem and having another student explain what part of the work should be done at that time.

In class each teacher reviews common assessments with the students and students are assigned the questions they got wrong. The students can go back to the test online to either print out or copy the questions they got wrong. The students are to then compare their wrong answer with correct answer and write an explanation for both. The explanation is to explain why the wrong answer is wrong and why the correct answer is correct, proof must be given with the explanation. If a student does not satisfactorily complete the assigned questions he or she will be expected to stay for after school tutoring, which occurs each day after school. Transportation is provided for the students in tutoring on Tuesday and Thursday.

2) How did you spend the required 50 hours for your learning plan? Report for each category.

they differ in the number of neutrons in each atom, the atomic mass, & their nuclear stability

For the Average Atomic Mass worksheet, the objective is to find the average atomic mass by using a specific formula. There is also problems on the back of the worksheet which are problems on isotopes. For the review packet, there are nine different worksheets that practice on a lot of different things like density calculations, physical and chemical changes, and the scientific method.
