Science Classroom Connection

Students: Make sure that you have printed and completed the following article assignment on Vacuum on a separate sheet of lined-paper to be turned in on Monday, April 08, 2019, upon your return from spring break. (If you are unable to print, you can still do the assignment with no problem; I’ll give you a copy if you need one upon your return to school. BUT THE ASSIGNMENT NEEDS TO BE COMPLETED OVER THE SPRING BREAK FOR FULL CREDIT, SINCE YOU HAVE THE ATTACHMENT ARTICLE BELOW!)

Vacuum Reading Directions

Guiding Question: Is a vacuum a medium?

C (Claim)

(Write a statement that responds to the question)

E (Evidence)

(Provide data to support your claim. Your evidence should be relevant & sufficient.)

R (Reasoning)

(Use knowledge that you have about the topic to explain WHY your evidence supports your claim.)

The scores for the ISN test have been posted.

Congratulations to those students that have earned an “A” on this test. You are well-organized. There were 30 of you. Keep up the great work!

The remaining ones need to stay on top of their material and be more organized so that they do not fall behind further.

Students, some of you asked about people who unable to hear. Here a diagram of the process for you.

“A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants do the work off damaged parts of the inner ear (cochlea) to provide sound signals to the brain.”*

Students, here is the information that you will be evaluated upon this coming Friday.

Topics include:

• Anchor Text #1 (What Is Sound?) & Anchor Text #2 (Auto-Tune). Reread articles and check you annotations.
• Videos: Glass Bottles (Billie Jean) and Glass Cups (Glass Music Xylophone)
• Glass bottle Exploration Activity & Its Expectations
• Note-Taking page (Sound, Mediums, Wave Parts, Auto-Tune)
• Vocabulary Foldable
• Brainpop Video on Waves & Self-Quiz
• Oscilloscope Virtual Lab Activity & Its Expectations plus Video

Make sure that your ISN is in order so that you will have all pertinent information, in order to succeed on the test this coming Friday.

Like our recent bellwork tests, we will be having an ISN test, due to the fact that many students have chosen to do a poor job on having an organized ISN. Therefore, those who are on top of their game in their organization skills are expected to excel on our Friday ISN test.

Note that this coming Wednesday, the students will be informed from what date to what date they will be held accountable for this upcoming short test.

Students see the attachment below for vocabulary terms and cross-check your work with the answer key.

Scores for both parts on Unit 2 have been posted. The total to look at is 82 points rather than 83; a question was dropped. Retakes will be discussed in class the week after this coming week, due to the fact that many students were either absent or school-related.

Once all of the makeups have occurred, corrected, and posted, retakes will be discussed. Until then, please refrain from pursing your classroom teacher for retake prior to the said schedule. Furthermore, remember that a retake is a different form of the actual test, since all questions have been shared on the iblog under the study guide posting.
