Today in class the students took the periodic trends performance assessment where they had to use their knowledge of groups/families and periodic trends to organize unknown elements onto the periodic table.
HW: None

Today in class the students took the periodic trends performance assessment where they had to use their knowledge of groups/families and periodic trends to organize unknown elements onto the periodic table.
HW: None Today in class we reviewed oxidation states in preparation for the periodic table performance assessment tomorrow. Afterwards, the students continued working on the Reactivity of Metals lab, performing various experiments to determine a trend in reactivity on the periodic table.
HW: Review for the performance assessment tomorrow Today in class the students began working on a lab to determine periodic trends in the reactivity of metals on the periodic table. We observed the reaction of various alkali metals in water, and then began testing the alkaline earth metals in water and dilute acid. Tomorrow the students will finish their experiments, and work to answer the question of "What is the most reactive metal?"
HW: Periodic Trends Performance Assessment Friday Periodic Trends Written Re-Assessment Tomorrow after school Today in class we discusses oxidation states, the charges that elements can obtain when ionized, and how to predict them using the periodic table. Following the discussion of oxidation states, we went over the assessment from last week and had an in-class review session for any students wishing to reassess.
All reassessments must be done Thursday after school. HW: Complete the Reassessment Study Plan by class on Thursday if you are reassessing. Study and prepare for the Periodic Trends Performance Assessment Friday Today in class we took our written assessment on the electron cloud model and periodic trends. The second portion, the performance assessment, will follow next week.
HW: None Today in class we reviewed for our written assessment tomorrow on the periodic table and trends. The students broke into groups based on their preferred study method to either review the study guide or complete practice problems.
HW: Complete 3 of the study questions that the class created last night for homework. These review questions can be found on Google Classroom and may be submitted online or in class tomorrow. Periodic Table & Trends Assessment tomorrow. Today in class we played a review game to help prepare for our assessment coming up this Friday. The students broke into groups of 4 with a stack of "element cards". After each receiving their stack of cards, they had to arrange them according to different criteria based on dice rolls.
Tomorrow we will do a more formal review in preparation for our assessment. The students should have their study guides completed by then to review any major issues. HW: Create two "test worthy" questions and submit them to Google Classroom by 9pm tonight (Wednesday) Complete study guide by tomorrow. Periodic Table and Trends assessment Friday. Start studying and asking questions NOW. Today in class we reviewed using models to predict electronegativity difference between atoms. Afterwards, we finished using periodic trends and clues to complete the periodic table project. Students who were unable to complete the project by the end of class today should seek extra time either before or after school before Friday to complete their project.
The students were also given a study guide to complete in preparation for their assessment this Friday. HW: Periodic Table and Trends Assessment this Friday (No Notes; Blank Periodic Table will be provided). Begin studying and seeking extra help now! Study guide due Thursday. Today in class we introduced our final trend, electronegativity. We used models to illustrate how different atoms would be more strongly attracted to electrons in bonds based on the strength of the attractive forces between their nuclei and the electrons.
HW: Begin reviewing for your test! Today in class we practiced how to approach a problem that deals with familiar concepts, but in a new (unpredictable) way. There students were presented with an isoelectric series, and and to rank them in order from the largest to smallest atomic radius.
They utilized models we have gone over in class such as: Bohr Model, Electron Configuration, and Orbital filling diagrams to determine the strength of Coulombic forces and highest occupied energy level the atom contains. With this information, the students were able to correctly order the elements & ions. HW: Use models to develop and explanation as to why the trend in ionization energy dips at the s- to p-block transition, as well as the group 15 to group 16 transition |
