                                                                      Big Ideas

A note to corps members:
You learned in an IL session that it is critical to deeply understand your objectives prior to planning a daily lesson, and you also learned that part of
understanding your objectives is connecting them to the “big ideas” of your content area. The statement below is meant to give you an overarching
picture of the “big ideas” of what Physical Science and specifically, Chemistry B is all about, and it was developed and reviewed by experts in
teaching this content. While the statement won’t necessarily incorporate 100% of all objectives you might teach, you should be able to connect
most of your objectives to a larger purpose found in this statement. In essence, this statement should help you answer the following questions,
both for yourself and for your students:
              Why are we learning this?
              How will mastering this objective be important over the long-term?
Being able to answer these questions will help you write more relevant key points, more valid lesson assessments, and stronger instructional
methods. To better understand how to use this statement, talk to educators with more experience in teaching this content area, such as your CMA
and your FA.
                                                         Big Idea of Physical Science
The physical sciences are about understanding physical laws, including:
 The properties of matter and energy, and the interactions between the two.
 The relationships between motion, force, and energy.
These understandings enable us to make predictions based on physical laws.

Underlying this content knowledge should be an overarching focus on building these scientific habits of mind:
 Collecting and synthesizing multiple types of evidence
 Generating knowledge and drawing conclusions
                                                            Big Idea of Chemistry B
Chemistry in a very important course in the high school science sequence. Students in Chemistry practice both literacy and math skills, while
simultaneously refining the basic chemical concepts developed in middle school science classes. Students will extend their knowledge of atoms,
molecules, and compounds through practice and experience with the Periodic Table. It is expected that students leave Chemistry with a strong
foundation as to what the Periodic Table shows and how it is organized. Ultimately, one of the major goals is to have students feel comfortable with
using it, reading it, and picking out important information. Though some standards (for example, the periodic trends) may seem to lack utility beyond
the scope of the course, these concepts, in reality, are excellent opportunities to practice critical thinking, analysis, and pattern recognition.
Students often feel empowered when they can use previously learned concepts and skills to make predictions or discern explanations on their own.
Unlike Biology, Chemistry is very much skills-based. This offers students the opportunity to extend their thinking and come up with their own
rationales to explain concepts (for example, electronegativity and its connection to the creation of an ionic bond). By using engaging demonstrations
                                                                                                                                                        2
and analogies, students are able to access the content more readily and feel more comfortable with the difficult vocabulary.
        The second goal of Chemistry is to leave students with unique enduring understandings that spark interest in the explanation of everyday
phenomena. Through the different units and strands, teachers and students are able to articulate unique properties of the world that are explained
through chemical principles. Some of these properties include: how hot and cold packs work, why a balloon expands or shrinks when placed in a
freezer or brought to the top of a mountain, why air freshener spreads in a room, why vinegar (acetic acid) is added to a salad, and many other
phenomena. It is up to the teacher to think “outside the box” and use their creativity to connect the chemical principles to everyday occurrences.
Though this can be difficult, one should not hesitate at all to extrapolate lessons beyond conventional boundaries and mold them to be engaging
and connected to students’ lives. Creativity is key, and by developing student rationale to explain real world applications of chemistry (or
connections to Biology, Physics, Earth sciences, etc.), students are more aptly set up for success to remember the desired enduring
understandings.

                                                          Author’s Notes

 Topic                                                                     Notes
                 Given time constraints of summer school and advising from district partners, specific standards from each strand of the CA
                 state standards were picked to include in the unit plan. Unfortunately, some pieces of information had to be omitted, as not
                 everything could be tested in such a short amount of time. Objectives were written to be as scaffolded as possible, in such
                 a way that an experienced teacher would do during a full academic year. Having said that, CMs may find the scope of
                 some objectives to be limiting (or a 45 min block too long to teach some skills/knowledge). It is important to remember
                 that, as chemistry can be very foreign and “intangible” to many students, repetition is one of the best ways to solidify a skill
                 or certain piece of knowledge. Taking a scaffolded objective and practicing it in new ways, often connecting it to recently
Chemistry
                 taught objectives is the best way for students to learn through repetition and build their confidence. Additionally, if a CM
                 feels limited by the scope of an objective, they should feel free to branch out and make connections to the skill or
                 knowledge being taught. A 45 minute lesson on a seemingly simple skill can go by very quickly and be extremely fruitful by
                 bringing in additional complexity (as the CM sees fit) beyond what is required from the pre- and post-tests. Going beyond
                 is not a bad thing at all, and as long as the core skill/knowledge is mastered any enrichment information is outstanding and
                 beneficial for students.

                           Assessment Administration Instructions


A note to corps members:




                                                                    14
An essential component to starting your summer off well is successfully administering your diagnostic assessment. You must first confidently
invest your students in trying their hardest on the diagnostic; then give explicit instructions for how to take the assessment and what to do when
they finish. You should give instructions verbally and have them written on the board or a poster.

                                                         Sample Investment Script:
Teacher to students: “Raise your hand if you’ve ever been in a class when the skills you were learning were too hard (wait). Raise your hand if
you’ve ever been in a class when the skills were too easy (wait). Raise your hand if that’s frustrating to you (wait). I have been in both of those
situations as well. We (state all teachers’ names), want to make sure that does not happen this summer. In order to do that, we need to know
exactly what you know and you need to do your absolute best on this assessment. When you do your best, it’s going to tell us what you know and
how we can be the best possible teachers for you this summer and lead you all to achieving your goal.”

                                                             Sample Instructions:

“Please clear everything off of your desks. Right now I am going to pass out the assessment. Please be silent and do not begin until I give you
permission to begin (Pass out assessments). Please write your first and last name at the top of the assessment and look up once you’ve done that
(Wait). Now, please put your pencils on the word instructions and read along silently as I read the instructions to you (Read instructions). Are there
any questions?

When you finish your assessment:
   1. Please go back and check over every answer;
   2. Flip over your assessment and place it in the upper-right hand corner of your desk; and
   3. Raise your hand so we know you are finished and we can give you the class survey.”

William Kvasnicka (Los Angeles ’08)

Welcome to LA Institute 2010. This High School Chemistry ISAT has been written by William Kvasnicka, a 2008 Los Angeles CM. William as spent
the last two years teaching chemistry at South East High School in South Los Angeles. He has described these last two years of teaching as “the
most formative years of his life” as he has grown immensely and learned about himself, his students, and the educational landscape of Los
Angeles.

During his second year of teaching William once asked his students, “Be honest with me, on a scale of one to fun, how do you think class is
going?” Though he expected some low numbers, he was surprised to see everyone give a genuinely positive response. One girl in the front row of
his class even went as far to say, “Mister, this is the class I look forward to most during my day.” It was a simple comment like this that made the
hours and effort he put into his job extremely worthwhile. At South East, William took on other leadership opportunities to expand and improve the
curriculum at South East High School. He became the facilitator of his Chemistry PLC, which organized and analyzed data in order to create
rigorous common lessons among teachers. Additionally, William helped the Chemistry CST Review program by designing and executing a review
curriculum on the Saturdays leading up to the CST’s in May. With the creation of rigorous and standards-based exams, he saw averages
consistently hovering around 80%. William attributes this success to the disciplined thought he put in to scaffolding his content and breaking it apart
for all students to be able to grasp. During his unit on bonding in his second year, he was able to tell his students, “You guys are doing college level
problems right now. And I don’t mean introductory Chemistry, I mean advanced Chemistry from upper level college courses!”

William is excited to be returning to Institute as an ISAT writer. In 2009 he worked as a School Operations Manager at LA Institute and in 2010 as a
o Corps Member Advisor. The ISAT is challenging. Everyone has their own way of planning and teaching, and it may be difficult to mold oneself
into using a document that was made for you and not by you. His hope is that, within this ISAT, you will feel empowered to extend objectives in
ways that you feel are appropriate and relevant. Effective scaffolding for difficult standards and objectives is present within this ISAT, but a CM
should seek out opportunities to insert their own perspectives and knowledge to make the chemistry experience that much more enriching for their
students. Good luck!
