Science Classroom Connection

ATTENTION STUDENTS: Due to our unpredictable weather conditions in Michigan, note that during our next school day, which is on Monday, February 04, 2019, we will be having a test on conversions between scientific notations and regular values like we have been practicing in class and at home through our homework assignments. Therefore, be prepared upon your return to school to take the scheduled test.

If you were absent on Friday, February 01, 2019, print, view, complete, and glue down in your ISN the attached video handout, below the video.

Handout: Eclipse Video Worksheet

Student see the attachment below for further practice on regular and scientific notations since we will be having a summative evaluation upon them sometime next week.

Scientific Notations Practice

Students make sure that you have completed the 2-sheet handout on regular and scientific notations by tomorrow, Wednesday, January 23, 2019, since we will be having a summative evaluation upon it early next week.

You want to start Marking Period 3 with this first summative evaluation on the right foot. Take advantage of it, because you are merely working with two mathematical notations only.

Midterm test scores have been posted. Results were mixed. Therefore, per your classroom teacher’s earlier class discussion, this particular test has been counted as 40% rather than the standard 80% for summative evaluations. Further discussion to be followed tomorrow, Friday, January 18, 2019.

Since students will be having abbreviated sessions/classes on Friday, Tuesday, and Wednesday of January 18, 22, and 23 respectively, we will be exploring and working on regular notations versus scientific notations, since scientific notation application may  be a key variable in learning certain scientific aspects in high school next fall.

Students, remember that we’ll be having our midterm this Thursday, since many of you have been asking, even though the classroom teacher has mentioned it last week.

See iblog entry dated January 9, 2019 along with the link for the study guide if you have not done so.

Students will be evaluated cumulatively on their learning of the subject matter for Semester 1. This evaluation will center on inquiry, analytical thinking, and problem-solving among other variables.

Again, here is the link for your Midterm Study Guide:

January 2019 Midterm Study Guide

ATTENTION SECOND HOUR: Since you are behind, you have been assigned a group number (1, 2, 3, or 4). Use your group number to answer, in your ISN, your set of questions that is attached below like you were informed in class today.

What Is an Eclipse – A Study Guide

ATTENTION HOURS 3, 4, 5, and 6:

Make sure that you work on and complete all remaining questions for the OTHER groups that you were NOT assigned in class, since you are responsible for knowing ALL the answers for the remaining questions for our future evaluation.

Students remember to complete the vocabulary tier 2 & 3 in the margins of your article handout titled, “What is an Eclipse?”

This will be verified tomorrow while you will be working independently on another new group assignment, using the same article.

Students below is the attached video link from our demonstration about magnetic field lines. View it and study the notes that are below it.

Key takeaways from the video:

“Faraday who realized that it’s a changing magnetic field that actually can generate electric current; so, as the magnet is falling through the pipe, it’s creating a changing magnetic field that generates little electric currents so called eddy currents in the pipe, and these create an opposing magnetic force on the magnet, slowing it down; so, it actually turns the pipe into an electromagnet, which pushes the magnet up, and this is what’s known as electromagnetic induction; so, causes the LED to light up, but it’s important that you the magnet moves quickly, because if you move it too slowly, the magnetic field is not changing fast enough to generate enough voltage to light this LED. This is actually the way all electricity is generated. You move a magnet near a conductor, and it creates an electric current. But where is this electrical energy coming from? You can’t get energy for nothing. Faraday realized that there must be a force pushing back on the magnet; it’s the same force that slows this magnet down, as it falls through the pipe; so, there’s actually energy being converted from gravitational potential energy into electrical energy and eventually heat energy; so, this pipe is warming up by taking some of the energy out of the falling magnet that these currents coming around; this way will induce a magnetic field, pushing in the opposite direction.”
