Welcome to 8th Grade Science!!!!

FYI: If I didn't specifically say to email or dropbox your homework, then the expectation is that you must WRITE IT or PRINT IT OUT BEFORE CLASS. If not, I won't accept it.

3/7

3 ways you can turn in the video:

1) Save to DVD and give me the disc.
2) Save to flash drive and copy to my computer BEFORE CLASS.
3) Upload to Youtube and send me the link.

HEre's the video project sheet:



Remember: PROGRESS CHECK IS ON MONDAY 1/7
DUE DATE: THURS. 4/7

8th:

TUESDAY:

NO 8TH

WEDNESDAY:

WORK ON ROUGH DRAFT

  • Steps 1-3 on the directions should already be completed. Work on steps 4-6, since these will take multiple days to thoroughly research and report. Most of your attention should be focused on step 4 today. They probably devoted most of their time to #4 on Monday as well. There are a lot of components, so I recommend they use the notes section to keep themselves organized.

  • Students can send me emails if they have any clarifying questions or concerns that you are unable to resolve. I will respond in the evening.

  • There is a copy of the 8th grade Characteristics of Life Project on my desk in the center for your reference. Cloe’s copy is in the 8th absent folder of the homework box. She can also download it from the previous post on the Wiki.

Please remind them that the draft should NOT simply be their research notes typed up. They should have transformed their notes into a well-organized paper. There is a BASIC outline of the paper written on their project handout that they should refer to for guidance. While grading the rough draft, I can help them decide which points to elaborate further upon to have a more solid paper for the final draft.


THURSDAY**:

WORK ON ROUGH DRAFT

  • DUE ON FRIDAY NO LATER THAN THE BEGINNING OF CLASS (12:40)
  • You must submit a paper copy (However, if anyone is absent from school that day, you are still expected to email the paper as an attachment ON TIME in order to receive credit.)
    • o No excuses/ No exceptions
    • o If you don't have a printer at home, it is your responsibility to plan ahead and have it printed from the school printer.
    • o You must include your list of sources with your paper so that I can verify that you are using reliable sources, and assist you if you are not
  • I will give you feedback Monday
  • Your final draft will be due WEDNESDAY (June 26)



14/6

Today we introduced your final project for the trimester. I will provide a second sheet on Monday to better describe the video portion of the project and the presentation requirements.
