        Q2: What electronic devices do I need to access the ChemExplained.com website?

        ChemExplained is available online from any computer, iPad or smart phone with internet access. With the ease and flexibility of this online program, students can learn chemistry at home on the computer, on their phone, in a classroom, in a car, on a bus, in the hospital, on vacation, in the airport or in any other place where Wi-Fi is available.

        top


          Q3: Why is learning high school chemistry important?

          Learning and understanding chemistry is important because more and more post-college careers are requiring students to take college chemistry. Colleges record (but don’t always report) that many of the students that register for their first year inorganic chemistry classes and second year organic chemistry classes drop out after the first few weeks. These students drop out because they were not properly prepared to take chemistry at the college level. Plus, in some states (i.e. Minnesota) all public school students must now take one full year of chemistry or physics in order to graduate from high school. Although homeschool students are not always bound by public school graduation requirements, taking a solid, math-based chemistry course is a good idea if a homeschool student has college chemistry aspirations.

            Q4: Can students of all academic ability succeed in taking this course?

            Absolutely. ChemExplained.com is designed with three types of student in mind; the Honor student, the Traditional student and the Foundational student.

            top


              Q5: How are Honor, Traditional and Foundational Students defined?

              1. The Honor student typically receives A or A- grades, does well in math, enjoys an academic challenge and is college bound. They have no problem with a fast-paced curriculum. They don’t need any modifications to the curriculum to succeed. Approximately 20% of students are in this category. The Honor student should cover all 20 chapters in ChemExplained.com.
              2. Most students are considered Traditional students. For the most part, this type of student has average or above average grades. Some are college-bound, some are not, but their desire is to be “college prepared” from the courses they take. Modifications may or may not be made, depending on the needs of the student. Approximately 60% of all students are in this category. The Traditional student will cover 15-16 chapters in ChemExplained.com.
              3. The Foundational student may or may not have grades that are C- or lower and they may or may not desire education beyond high school. School is usually challenging and modifications (i.e. using their notes on the tests) are usually made in taking the course. Approximately 20% of the students, or 1 in 5 students are in this category. The Foundational student will cover 12-13 chapters in ChemExplained.com.

                  Q7: What are the main differences between ChemExplained.com and other online chemistry courses?

                  ChemExplained.com comes with a TEACHER!  This means that the #1 difference is the 365+ teaching video podcasts!  The students do not have to read a textbook and try to figure out chemistry on their own.  Ask the students that have done this.  It’s frustrating!  As the student listens to Mr. Riz, a licensed professional chemistry instructor, the student will be engaged in learning even difficult chemistry concepts in a way they can understand. Difference #2 is the rigor and success of the course which will help the student take their understanding of chemistry to the next level.  Students that successfully complete the ChemExplained.com course do NOT drop out of chemistry at the next academic level; in fact, most students earn A’s and B’s.

                    Q8: Who teaches in the ChemExplained.com podcasts?

                    Richard Risbrudt has been a high school chemistry teacher for 44 years, teaching at a private Christian high school for 29 years and now at a community high school for the last 16 years. Over the years he has learned to teach and explain chemistry in language, examples and problems that thousands of students could understand. He has mastered chemistry concepts and the math associated with those concepts. Students that have completed his chemistry courses have been very successful in chemistry courses at a higher academic level. Richard’s teaching honors include the Ashland Oil Excellence in Education Award, Fergus Falls (MN) Teacher of the Year Award, the Chamber of Commerce Excellence in Education Award, and certificates of recognition for his outstanding teaching from three Minnesota Governors; Rudy Perpich, Arne Carlson, and Jesse Ventura. He has been recognized as the high school’s, “Most Influential Teacher” five times.  Richard was encouraged by homeschool parents, many of them former students, to create a chemistry curriculum where chemistry could be taught, explained, AND understood by their children as well.

                                      Q17: How do I use the Student Lecture Notes and Worksheets for each Chapter?

                                        1. Once the student lecture notes are downloaded from ChemExplained.com and printed out, they are used as a self study guide in the following manner:
                                        1. A STAR symbol followed by a Title in the notes indicates it is now time to watch a teaching video online.
                                          – Login to ChemExplained.com and watch the video covering the same title as identified in the notes.
                                          – The Student will actively fill in the notes along with the Instructor.
                                          – The student can pause or replay the video as needed.
                                          – Each video will last from 8 to 15 minutes and there are 2 to 5 videos per unit.
                                        2. A BOXED area identifies a chemistry worksheet and the chapter number and subject are shown.
                                          – When the student has listened and filled in their notes to this point, the student’s assignment is to complete the worksheet.
                                        3. When lecture notes and worksheets are complete use the answer keys found in the Teacher tab to correct them:

                                                      Q25: How much time should a student spend on high school chemistry each day?

                                                      When we travel across the country to various homeschool conferences, this is a common question. Here is a fact: If you really want your child to be prepared for the next academic level, learning real high school chemistry, from the right company, doing it the right way, being taught by a real teacher, does not include many short cuts. Some science companies advertise their course as “high school level” when in reality, it is not. 7th, 8th and 9th grade level chemistry classes are not high school chemistry. Here is another fact: If we didn’t homeschool our kids, they would be attending a ~50 minute chemistry class each day in a school somewhere. They would receive on average, between 0 to 30 minutes of homework each day doing worksheets, lab reports, reading, etc. (0 minutes of homework means students are able to get their homework done during class time.) Add those two numbers together and students spend anywhere from 50 to 80 minutes doing chemistry each day.  Also, by asking this question, this leads us to ask you this question: “How much high school chemistry do you want your child to learn?” The entire 20 chapter ChemExplained course has ~90 hours of video instruction. For a 180-day school year, that’s an average of 30 minutes of watching teaching videos per day. The rest of the time can be spent on doing labs, worksheets and tests.

                                                        Q26: In many places on your Foundational, Traditional and Honor student Calendars, it says to “Podcast Ahead.” What does that mean?

                                                        ChemExplained is not a chemistry course that starts out easy in the first chapter and then gets progressively harder with each subsequent chapter. Yes, the course “builds” on what was previously learned, but depending on the topic, the material may be very easy, difficult or somewhere in between. On our ChemExplained calendars, students are encouraged to “Podcast Ahead,” or work ahead on what’s coming next whenever they have extra time. Students that “quit for the day,” because they’ve completed the day’s assignment in a few minutes, will wish they had more time when they come upon a chemistry topic that is more demanding. If a student “podcasts ahead” whenever they are able, and uses their time wisely and efficiently, they will never run out of time when it comes to understanding a more challenging topic.

                                                          Q27: Does ChemExplained have Labs?

                                                          Absolutely! ChemExplained has 18 lab experiments and activities in all. High school chemistry is a course that needs to be taught by a real teacher, that does real experiments, with real lab equipment and real chemicals. At ChemExplained, the student has the best of both worlds when it comes to doing labs. For all 18 labs, students can watch Mr. Riz explain and perform the experiment/activity on video . . . or they can do the experiment/activity themselves . . . or BOTH! Most students choose to watch Mr. Riz do the experiment first, and then try it themselves. While others do the experiment at the same time as Mr. Riz, following along step-by-step.

                                                            Q28: What happens after a student performs or watches Mr. Riz do an experiment?

                                                            All 18 ChemExplained lab experiments/activities come with easy-to-follow lab report sheets, also called lab write-ups. These lab sheets include: TITLE (name and number of the experiment); SAFETY PRECAUTIONS (safety rules for all students to follow because this is our #1 concern); OBJECTIVES (what we can expect to learn); EQUIPMENT and MATERIALS (what is needed to do the experiment); PROCEDURE (how to do the experiment step-by-step); OBSERVATIONS (what we notice and know happened); DATA TABLE (values obtained that are used to do our calculations); EQUATIONS (what is going on chemically in the experiment); CALCULATIONS (used to help us understand the math behind the experiment); TABLE of PHYSICAL PROPERTIES (a chart that tells us important properties about the substances involved); QUESTIONS and CONCLUSIONS (help us to think critically about the experiment performed); and RESULTS (how well we did the experiment). All lab sheets are found in the Student Lab Manual or can be printed off the website. When completed by the student, these lab sheets are corrected and recorded as part of the student’s grade. The answer keys for all 18 labs are found in the Teacher Resources Manual and the Teacher tab on the website menu bar.

                                                              Yes. Prior to a student or parent having access to any ChemExplained laboratory experiment/activity resources, they must agree to a one-time acceptance of the ChemExplained.com Lab Safety Agreement and Contract. To do this, click Student on the menu bar, then click Lab Resources (purple button), then click Enter the Laboratory (door), then follow the instructions. Download and print off the Lab Safety Agreement and Contract and keep it in the student’s three-ring binder.

                                                                All this information is found in the Master Lab Equipment and Supplies list found in the Teacher tab on the menu bar (red button). This 9-page PDF document can be downloaded and printed off so the parent knows exactly what lab equipment and supplies are needed for each experiment/activity. In addition, there are easy to follow instructions of where and how to order what is specifically needed in each lab. With many of the supplies found in most homes, the lab equipment and chemicals can be ordered from our recommended supplier; Home Science Tools in Billings, MT or Amazon.com

                                                                  In a perfect world, the answer is yes. But our world is not perfect. Is it best to cover everything in ChemExplained? Yes. Is it realistic? Probably not, but it would be a great goal to set! Consider this: If a teacher hands out a thick 26-chapter history textbook at the beginning of the school year, will the class be able to get through every chapter and do every assignment and answer every question from cover to cover in that textbook? Probably not, unless each student wants to and is given more time! In reality, the teacher will get as far as they can, with the time they have to work with. That’s the beauty of ChemExplained – FLEXIBILITY! Each parent has the discretion to do what’s best for their child and cover as many chapters, and do as many labs as they can, with the time they have according to their schedule.

                                                                  top

                                                                      First, ALL of the ChemExplained labs are high school quality. We use real chemicals in our labs that are taught by a real chemistry teacher. Students in ChemExplained can do the labs virtually together with the instructor as he goes through the experiment or they can do it themselves by ordering the equipment and supplies through our recommended supplier mentioned in Question 30. Most students do both. Rather than require a specific lab kit for all 18 labs, we let parents decide which ones they want to do and then order the supplies from there. The labs typically performed by our homeschool students are Labs 1, 2, 3, 4, 6, 8, 10, 11, 12, 16, 17, 18. Labs typically watched and completed virtually are Labs 5, 7, 13, 14-15. These labs use more chemicals which increase the cost. Students involved in a co-op do most or all of the labs because they share in the expense.

                                                                      top

                                                                        ChemExplained is a college-prep high school chemistry course that is neutral. We do make a statement at the beginning of Ch. 3 that states, “The diversity of matter in the world and in the universe is so astounding that only God or the Big Bang could have created it!” In the course, we do not talk about the origin of the Earth or evolution. Other than that, we believe that chemistry is chemistry and we leave it at that. FYI – The instructor that wrote the ChemExplained curriculum has 46 years of experience teaching in a private Christian school, a public high school and an Area Learning Center in the State of Minnesota.
