Mrs. Brown’s Earth/Environmental Science Class

The Great Pacific Garbage Patch

BOYAN SLAT Born July 1994 (now 26 years old)   In 2011, at age 16, Slat came across more plastic than fish while diving in Greece. He decided to devote a high school project for deeper investigation into ocean plastic pollution and why it was considered impossible to clean up.    He later came up with the idea to build a passive system, using the circulating ocean currents to his advantage. He founded The Ocean Cleanup in 2013, and shortly after, his TEDx talk went viral after being shared on several news sites.   It raised US$2.2 million through a crowd funding campaign with the help of 38,000 donors from 160 countries.

There are 1,000 rivers that contribute to 80% of the plastic that gets into the ocean. Many are in Indonesia, China, India, or Africa.

TEST Mon 1/13 and Tues 1/14

The last test of the second quarter will be on Monday and Tuesday for Surface and Groundwater. The Honors test will be worth 93 points and the Academic Test will count for 90 points. The flashcards for the test are located in the previous post and can count for extra credit on the Test if you bring them with you to class on test day. These grades will be the final additions for the semester. Our next unit on Oceanography will begin the 3rd Quarter grade book in Powerschool. Please study so that you can finish the Quarter strong!

Surface and Groundwater Unit

Our Test for Surface and Groundwater will be Monday Jan 13th for A-Day and Tuesday January 14th for B-Day. Remember that you can make flashcards for extra credit on the test. Just bring you flashcard set to class on test day. Here are the flashcards for this test.

Using your cellphone, or prohibited technology, during a Test (or even during class) can get you into big trouble at Broughton High School. Certain violations in the classroom can trigger a chain of events that are outside my control. Violations of Honor Code or the Integrity Policy have a set procedure that must be followed according to Wake County School Board Policy. It involves an official discipline referral to the Principal with consequences, notifying the parents, as well as a different assessment for the offender. An additional reminder that “Cheating” does include taking a picture of your work to send it to another student. Using Copies of review sheets is never permitted during Testing. A dishonest act can keep a student from participating in the certain Honor Societies at Broughton and may have repercussions for student-athletes. As we enter 2020 let us recommit to follow the rules outlined in the Student Agenda.

Here is the Powerpoint for Phases of the Moon and Eclipses

The Test for this unit will be Wed Dec 4th for B-Day and Thursday Dec 5th for A-Day. There are Test diagrams that cover eclipses, tides, phases of the moon, etc. I also have created a flashcard template for most of the Vocabulary on the test.

Weathering, Erosion, and Soil

The Test for our new unit on Weathering, Erosion, and Soil will be Wed Nov 6th for B-Day and Thursday Nov 7th for A-Day. B-Day will lead this unit after Halloween due to our Make-Up day creating TWO B-Days in a row! (B-Days =Thurs Oct 31st and Monday Nov 4th)

Here are the flashcards for this unit–PLUS a few test diagrams to use in your study.

There will be 2 Honors assignments for this unit. The first will look at the events that led up to the Dust Bowl in the 1930’s Plains States. We will use two video clips to examine this work: Ken Burns’ PBS documentary “The Dust Bowl” and the Science Fiction Movie “Interstellar” directed by Chris Nolan. Here is a companion document to help guide your analysis of the Science Fiction viewpoint versus the PBS documentary (based on the actual event).


The Test for Earthquakes, Faults, and Volcanoes will be Tues 10/22 for A-Day classes and Wed 10/23 for B-Day classes. Flashcards for extra credit are located in a previous post, and are due on Test Day.

HONORS students must turn in their project by their class period Tues or Wed. If you need links, rubrics, or clarification please visit the earlier post where those items are located. My “Teacher Notes” has links that may be helpful. Remember, you should consider the wider area around your location. For example, If you have Los Angeles search for Quakes in California. Search for all quakes or volcanoes in Mexico if you have Mexico City. Don’t focus solely on your city. For example, Search for most recent earthquakes on the Canary Islands-or recent volcanic eruptions in Hawaii. Include only the most recent 10 events or so. If you have a Powerpoint or Google Slides SHARE with me at

New Quakes and Volcanoes Unit

Our Test for Earthquakes, Faults, and Volcanoes will be Tues October 22nd for A-Day classes and Wednesday October 23rd for the B-Day classes. The Honors projects are due on the same day, Honors students should be prepared to talk/present for approximately 3 minutes on the work that they did. I would prefer that the Honors students turn in a paper copy of your Powerpoint or Google Slides, but you can e-mail it to me at
